106 FXUS66 KSEW 272328 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 328 PM PST Tue Jan 27 2026 .SYNOPSIS... A front, the first in a series of systems, is approaching the region this evening. Expect additional disturbances to track across the region over the next several days, each bringing an increase in precipitation coverage and gusty winds as they approach and cross the area. High pressure is expected to rebuild over the weekend, with another disturbance around Sunday. High pressure then is likely to return next week. && .SHORT TERM /TODAY THROUGH THURSDAY NIGHT/... The leading edge of the next weather system is continuing to advance toward the coastline this afternoon, bringing an increase in gusty winds to the coast along with precipitation offshore that is evident on radar. We`ll see this precipitation continue to spread inland tonight through early Wednesday. While the precipitation will initially be in the form of light snow for most of the Cascades, there`s a small (10-20%) chance of brief freezing rain given the surface cooler air; given the light precipitation and marginal profile, this remains a low probability scenario. Precipitation will remain more widespread over the next few days as additional disturbances reach the area. Snow levels will be rising to around 4500 to 5000 ft by Thursday, but depending on where the plume of moisture and warmer air sets up, this could vary more significantly from north to south over the Washington Cascades. That said, the bulk of the precipitation will be focused along the Olympic Peninsula and this is where the flood potential remains the highest - see the HYDROLOGY section for additional details on this concern. This active weather will also result in gusty winds, mainly for the coast and the areas from Island County northward. Meanwhile, waves near the Pacific coast are expected to approach 18-20 ft late Wednesday into Thursday, bringing the potential for high surf conditions. && .LONG TERM /FRIDAY THROUGH TUESDAY/... Ensemble systems are in lock-step regarding the 500 mb pattern in the long-term forecast. Their solutions favor general upper-level ridging over the West Coast and upper-level troughing over the Gulf of Alaska and NE PAC. This set up will allow for moist southwesterly flow over the region as a series of fronts enter W WA with the first arriving on Friday. Drier weather on Saturday barring a few showers before the next disturbance takes aim on Sunday and so forth. Reoccurring spells of widespread rain and possible breezy with are expected. Snow levels remaining above the passes through the period. Temperatures will remain above average as well with highs in the lower to mid 50s and lows in the upper 30s to mid 40s. McMillian && .AVIATION... An upper level ridge has shifted east of the Cascades this afternoon as an upper-trough looms offshore. With that, south-southwest to southerly flow aloft will prevail. Conditions across area terminals are VFR with mid to high cloud cover streaming in ahead of a frontal system that will move into western Washington this evening. Winds will increase out of the south overnight to 10-20 kt (with gusts to 25-35 kt possible) as the front approaches. The strongest winds will be observed at KBLI. Winds will subside into Wednesday but remain breezy at times. Rain looks to arrive at the coastal terminals late this afternoon (00-02z) and then break into showers as it pushes inland into the interior by this evening (after 04z). Conditions generally look to remain VFR with the arrival of rain showers tonight, but look to gradually decrease to MVFR overnight into Wednesday morning and remain into the day on Wednesday. KSEA...VFR conditions expected to persist at the terminal this evening. However, a front will arrive overnight with the potential for MVFR cigs and breezy southerly surface winds. Brief gusts to 25- 30 kt will be possible at times. Rain showers will likely make it into the terminal between 04-06Z. As mentioned, MVFR conditions are favored to develop at the terminal by Wednesday morning as the HREF is showing 40-60% chance of cigs below 3,000 ft and a 15% prob of cigs below 1,000 ft. Confidence is leaning towards a mix of VFR/MVFR throughout the day on Wednesday. McMillian && .MARINE... Increasing southerly winds over the coastal waters this evening ahead of the frontal system. These stronger winds will expand to the eastern Strait of Juan de Fuca as it moves inland this evening. Small craft southeasterlies are also expected across the remaining marine zones immediately with the front (except for the central Strait). Seas across the coastal waters will build around around 6 ft this afternoon to 10-14 ft overnight. Another system will move across the area waters Wednesday into Thursday, which looks to bring another round of gales to the coastal waters and to the eastern Strait (around a 60-70% chance of gales). In addition to winds, seas will build across the coastal waters to 15-20 ft late Wednesday into Thursday. The pattern will remain active over the weekend, with additional systems expected to move across the area waters. Seas will gradually subside on Friday, but look to remain elevated and range between 10-12 ft through the weekend. && .HYDROLOGY... After an extended period without appreciable, or any, rainfall, multiple rounds of rain will fall over the area through Friday to once again start juicing up area rivers. Rainfall totals will be most pronounced on the Olympic Peninsula. Precipitation on the south slopes of the Olympics, along with snow levels rising from 4000 feet up to 6000 feet, will cause the Skokomish River to begin rising out of its doldrums Wednesday. The river could then reach flood stage as early as Thursday morning but more likely later in the day. The river will remain above flood stage into Saturday. No river flooding expected on the remainder of the rivers. && .SEW WATCHES/WARNINGS/ADVISORIES... WA...None.

520 FXUS66 KPQR 272322 AFDPQR Area Forecast Discussion National Weather Service Portland OR 321 PM PST Tue Jan 27 2026 .SYNOPSIS...The first in a series of frontal systems will push across the area later this afternoon and evening, followed by post- frontal showers tonight into Wednesday morning. Most locations are expected to see measurable precipitation with this system. Light freezing rain is also possible in the central Columbia River Gorge and upper Hood River Valley. The next frontal system will bring another round of rain Wednesday night into Thursday. A few more systems are expected to push across the area Friday, and again on Sunday, though drier and seasonably warmer weather is likely for Saturday. Uncertainty increases early next week, but ensembles are trending drier toward the middle of next week. && .SHORT TERM...Now through Thursday Night...Water vapor satellite imagery this afternoon shows an elongated upper level trough lifting northeast toward the Pacific NW. A frontal band remains offshore but is expected to push inland later this afternoon through this evening bringing a round of light rain to the area. The front will likely fall apart as it moves inland, with inland valleys being ran- shadowed as well. Post-frontal showers develop later tonight and continue through Wednesday morning as the upper trough passes over the area which will bring another round of light to moderate rain, with higher amounts expected along the coast and coast range north of Newport, OR and into the foothills of the south Washington Cascades. Total rainfall amounts through Wednesday afternoon will likely fall within 0.25-0.50 inch at the coast and around a tenth of an inch inland. While precipitation amounts are expected to be light, there is the potential for freezing rain tonight into Wednesday morning in the central Columbia River Gorge, upper Hood River Valley, and into parts of Skamania County, where colder pooling of near to below freezing surface temperatures will likely persist. Guidance suggests there is at least a 30-50% chance of 0.01" of freezing rain, and around a 10-20% chance of exceeding 0.10". This could produce slick roads. Snow levels are generally expected at around 4,000-4,500 ft, except in the central gorge and upper Hood River Valley, where snow levels around 1500-2000 ft should quickly climb overnight. Still not expecting more than an inch or two of snowfall at pass level in the Cascades. Most accumulating snowfall is expected to remain confined to the higher Cascades above 5,000 ft. The next frontal system approaches the coast later Wednesday as a warm front lifts across the area. This will bring another slug of moisture and steady rainfall, highest amounts again across the northern portions of the forecast area. Snow levels continue to rise Thursday to at least 6,000 ft as another warm front lifts across the area. Rain should diminish from south to north Thursday night. /DH .LONG TERM...Friday through Tuesday...A progressive and amplified weather pattern continues through the weekend and into early next week. Frontal system in the NE Pacific will bring periods of rain and dry weather through this long term period. Ensembles provide a little more clarity than 24-hours ago with these systems Friday through the weekend, though there still remains some uncertainty with total rainfall amounts with the frontal systems Friday and Sunday. A frontal band to the north associated with some weak to moderate IVT values (atmospheric river sub-tropical moisture) will likely push across the area on Friday. A few ensembles show potential for that band to hang up along the northern Oregon coast and parts of southwest Washington, but those numbers have been decreasing with total ensemble mean rainfall amounts trending lower. Another warm front lifting north may clip the coast, but most ensemble members are indicating mostly dry weather for Saturday with offshore flow and warmer than normal temperatures likely. WPC 500 mb cluster analysis shows good agreement of a slightly stronger and more negatively tilted upper ridge extending north over the west coast on Saturday. Rain likely returns on Sunday, the first of February, as the ridge transitions east and offshore front pushes inland. More uncertainty into early next week, but models and their ensembles seem to be trending drier as frontal systems remain offshore and clusters showing an anomalously strong upper ridge building into the middle of next week. /DH && .AVIATION...Predominately VFR conditions continues, but probabilities increase for sub-VFR conditions this evening as a cold front moves through the area, bringing widespread rain showers. Light rain is moving inland from the southwest and is expected to spread northeast with rain reaching inland terminals by 01-04z Wednesday. Probabilities for MVFR conditions along the Coast and higher terrain of the Coast Range and Cascades increase to 30-50% after 00z Wednesday and again to 50-70% after 05z Wednesday, continuing through the rest of the TAF period. Probabilities are lower at 10-20% for the same time period in the Willamette Valley, increasing to 40-60% for the Portland area terminals between 07-15z Wednesday. A continued offshore pressure gradient is creating east to southeast winds through the Columbia River Gorge including KTTD with gusts to 30-35 kt. Winds will slowly ease as the front approaches, generally after 01-04z Wednesday. Still expecting light freezing rain or wintry mix in the central Columbia River Gorge and Upper Hood River Valley due to lingering cold air. Accumulations will generally stay below 0.1 inch, with the highest probability around 0.01-0.05 inch. However, slick surfaces and ice accumulation on area runways and outdoor surfaces is likely. KPDX AND APPROACHES...Mainly VFR conditions expected through the period. A frontal system will bring a chance for light rain after 02-04z Wednesday. Low chance (10-20%) of MVFR conditions after 03-06z Wednesday as rain increases and the cloud deck begins to lower, increasing to 40-60% chance between 07-15z. Easterly winds around 10 kts expected to shift more southeasterly after 06-08z behind the front. -03/19 && .MARINE...A front is moving through the waters this afternoon with increasing south to southeast winds. Expecting a period of Gale Force wind gusts 35-40 kts in the outer waters from 10-60 NM out from the coast directly ahead of and along the front, with peak gusts falling below 35 kts quickly behind the front. A Gale Warning is in effect until 10 PM PST. Additionally, the front will weaken as it approaches the coast, and gusts for the inner waters out 10 NM from the coast and for the Columbia River Bar will mainly be sub- gales, up to 25-30 kts with isolated gusts up to 35 kts. A Small Craft Advisory is in effect for the inner waters into Wednesday. Winds across all waters shift southwesterly behind the front and decrease to 20-25 kts by early Wednesday morning before another frontal system begins approaching the waters, with south winds increasing again through Wednesday to 25-30 kts. There`s around a 30-40% chance of isolated hourly gusts reaching gales (34+ kts) in the outer waters with the next frontal system Wednesday night, but currently not expected enough widespread gusts for another Gale Warning. Behind tonight`s frontal system, a persistent westerly swell will quickly build seas to 11-14 ft at 10-11 seconds overnight. Seas decrease slightly by Wednesday morning but are expected to remain around 10-12 feet through Wednesday before another stronger westerly swell increases seas to 15-18 feet Wednesday night into Thursday behind the next frontal system. Because of the elevated seas, a Hazardous Seas Warning will take effect for the outer waters at 10 PM PST tonight after the Gale Warning ends. It will take time for the elevated seas to impact the inner waters, so a Hazardous Seas Warning is in effect beginning at 4 PM PST Wednesday for the inner waters and the Columbia River Bar.

803 FXUS66 KMFR 280030 AFDMFR Area Forecast Discussion National Weather Service Medford OR 430 PM PST Tue Jan 27 2026 .UPDATE...Aviation Discussion Updated. && .AVIATION...27/00Z TAFs...A front is moving inland this evening bringing areas of gusty winds and areas of rain. Gusty winds will continue through around 03z, including in the Shasta Valley (with gusts up to 45 mph) and east of the Cascades (gusts of 25-40 mph). Along the coast, low level wind shear is expected through around 03z. Rainfall will be most prevalent along the coast and coastal mountains but light rain and snow will also spread inland during the evening with the frontal passage. Snow levels of 4500-5000 feet will keep light snowfall limited to mountains and areas east of the Cascades. Precipitation with this front may locally lower ceilings and visibility to MVFR, especially this evening, as well as obscure elevated terrain. Klamath Falls may see a mix of rain and snow this evening with MVFR conditions. Behind the front, late tonight and Wednesday morning, expect mainly VFR with some continued mountain obscurations in light showers. Showers may continue, off and on, into Wednesday, mainly for the coast, Umpqua and Cascades. There is a chance (20-25%) for IFR or MVFR ceilings to develop in the Umpqua Valley, including Roseburg, early Wednesday morning. Confidence is low in this occuring, so we will continue to monitor and update as needed. && .PREV DISCUSSION... /Issued 241 PM PST Tue Jan 27 2026/ DISCUSSION... Key Points: * Widespread hazardous weather is not anticipated this week * Gusty winds today for Rogue/Shasta Valleys - Wind Advisory remains in place for Shasta Valley * Precipitation chances mainly west of the Cascades through Sunday - Overall, total amounts are low for many areas - Coastal areas upwards around an 1.00"-1.50" for totals - Interior ridges and mountains closer to 0.50"-0.75" totals * Light snowfall amounts for higher elevations above 4500ft - Will not warrant any hazards this week Further Details: Breezy to gusty winds anticipated through late this afternoon/early evening. A wind advisory remains in place for Shasta Valley through 7pm, but we canceled the advisory for the southern parts of the Rogue Valley. The Rogue Valley advisory was borderline and hasn`t been reaching criteria this afternoon so decided to cancel it. Much of the westside has a low probability (10%-40%) of reaching 0.10" in any 6hr timeframe this week with much of these "better chances" over the next 24 hours. The coast and areas near the coast (including western Josephine County) have a much better chance at 50%-90% for 0.10"/6hrs. Areas along/near the coast in central to southern Curry County likely to see the higher rainfall totals near 1.00"-1.50". Much of this rainfall will come in the next 24 hours as probabilities drop off after today, but light rainfall chances anticipated to continue through the week. The takeaway here is that this precipitation and subsequent precipitation this week is not going to produce any hazards and will likely be a beneficial rain for most areas. Cluster analysis of 500mb continues to indicate ridging aloft will be favored through Day9 over the PacNW. Guidance from the Climate Prediction Center (as of today) continues to indicate in their 8-14 day outlook a very strong signal for above normal temperatures in addition to a strong signal for below normal precipitation. This completely aligns with the cluster analysis, and may be a telling sign for early parts of February being above normal for temperatures and overall dry. This has been a consistent forecast trend the last several days, so confidence is high for this scenario across the forecast area. -Guerrero MARINE...Updated 200 PM PST Tuesday, January 27, 2026...A frontal system today will bring gale force south winds and very steep, hazardous seas peaking at around 10-15 ft at 10 seconds. Isolated thunderstorms are possible this afternoon and evening with localized wind gusts to 50 kt. Hazardous conditions reach a peak this evening, then gales ease to advisory levels with seas remaining steep to very steep tonight into Wednesday. A building long period west swell is expected Wednesday night into Thursday, which will maintain steep seas. This long period west swell is expected to peak at around 13 to 17 ft at 15 seconds. South winds are likely to remain near or above advisory strength Wednesday into Friday, with seas remaining steep. The outlook for the weekend is for south winds to diminish with seas becoming dominated by another steep, building west swell. && .MFR WATCHES/WARNINGS/ADVISORIES...

160 FXUS66 KEKA 272220 CCA AFDEKA AREA FORECAST DISCUSSION...CORRECTED National Weather Service Eureka CA 220 PM PST Tue Jan 27 2026 .SYNOPSIS...Widespread light to moderate rain this afternoon through early evening will be followed by generally drier weather conditions for much of Northwest California Wednesday through Saturday. Widespread light to moderate rain is expected on Sunday. && .DISCUSSION...Surface observations have been reporting gusts in excess of 50 mph (64 mph at Kneeland RAWS) this afternoon. Lower elevations around Humboldt Bay and Eel delta have gusted to 35-40 mph (KACV and KFOT) as well. So far winds have not picked up at KCEC. Gusts from 45-50 mph per the HREF mean are expected by late afternoon today. A wind advisory for strong and gusty winds for coastal Del Norte and higher elevations of Del Norte and Humboldt Counties remains in effect til 4-6 PM. Southerly winds will rapidly decrease with frontal passage after 4-6 PM as mostly light to moderate and perhaps locally heavy rain develops late this afternoon and evening. HREF continues to indicate a 1 hour window from 3-5 PM for rain rates over 0.25in/hr over SW Humboldt in the King Range. The progression of the cold front, dry antecedent conditions and low flows on the rivers will severely limit potential for any major hydrological impacts. Amounts will generally range from 0.25 to 0.50 inch through 10 PM Tue for Del Norte, Humboldt and NW Mendocino. Lesser amounts from 0.1 to 0.3 inches are expected for Lake County and southern Mendo. We posted estimated rainfall amounts for select cities on our web page and social media outlets. Dew points remain in the mid to upper 20`s across northern Trinity this afternoon. Evaporative cooling could result in lower snow levels and slushy wet snow down to 2500-3500 feet around Trinity Center this evening. No accumulations are expected. 2 to 3 inches of snow is forecast in 6 hours for Scott Mountain Pass on route 3 this evening. This is below advisory criteria for a winter weather advisory. Motorist traveling over the high mountain passes above 4500 feet this evening should be ready for slippery roads. High pressure is expected to return Wednesday afternoon and dominate across much of the forecast areas through Saturday. Light rain or sprinkles with a series of warm fronts will be possible (20-50% chance) primarily for Del Norte and northern Humboldt, particularly in regions of southerly upslope flow. Overall it does not look too wet or impactful with amounts on the order of few one hundredths to perhaps (15% chance) for a tenth in 6 hours across Del Norte. Global ensembles and WPC guidance indicates more widespread light to moderate precipitation this weekend as another shortwave trough heads toward the Pac NW. There is still a some variability with the amounts of rain and timing, however Sunday appears to be the day when most of the rain arrives. Gusty winds will be possible as well in advance of a frontal boundary. Right now 925mb winds do not look strong enough to warrant beefing up the winds above the NBM. Multi-model ensemble continues to indicate a 40-60% chance for 0.25-0.50 inches in 24 hours ending 4 AM Mon, mostly for the northern most zones. Chance for major impacts from rain or snow remains low at this time. Drier weather is expected to return early next week, Mon-Tue, as a ridge aloft builds and light northerly to northeasterly surface winds return. && .AVIATION...(18Z TAFS)...Largely VFR conditions have persisted during the day, though notably gusty south winds and upper level overcast skies have both built in during the late morning and early afternoon. Gusty winds up to near 40 kts will continue until near sunset as a quick moving cold front crosses the area. This will generate gusty surface conditions and modest low level wind shear, especially along the coast. Light rain showers will begin to impact the coast around 2 PM local time. SOme briefly heavier showers are possible through around 7 PM. MVFR visibilities will most likely prevail with brief period down to IFR. Behind the front, lingering instability will likely bringing a return to VFR conditions late overnight though the there is a 30% chance of lingering MVFR ceilings. Similarly for the interior, VFR conditions are most likely though some models indicate a chance (20%) of low valley fog around sunrise Wednesday. /JHW && .MARINE...Gale conditions have built across the outer waters during the day today with some gale conditions pushing close to shore int he inner waters. Some brief gusts up to 40 kts have so far been recorded. Gale conditions will continue into the early evening as a cold front passes the area. Steep short period seas will also build along the wind, up to around 10 kts by later this afternoon. South winds will quickly drop off behind the frond with few gusts even over 15 kts by midnight. Short period seas will also fall, with combined seas likely briefly below 6 feet Wednesday morning. Aside from some moderate gusts up to 24 kts in the outer northern waters Wednesday, wind will be mostly gentle with only moderate short period seas. That said, a steep long period swell up to 14 feet will build in Wednesday evening and persist into early Friday. More moderate conditions will them most likely build for the weekend. /JHW && .EKA WATCHES/WARNINGS/ADVISORIES... CA... Wind Advisory until 6 PM PST this evening for CAZ101-102- 105-106.

595 FXUS66 KMTR 272139 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 139 PM PST Tue Jan 27 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 136 PM PST Tue Jan 27 2026 - Light rain returns tonight across the North Bay and portions of the Bay Area. Up to 0.5" of rain across the North Bay and up to 0.1" across portions of the Bay Area - Warm, dry weather and weak offshore flow return by Wednesday afternoon and continue through late week - Beach Hazards Statement for increased risk of sneaker waves and riptides Wednesday night through Friday Morning && .SHORT TERM... Issued at 136 PM PST Tue Jan 27 2026 (This evening through Wednesday) An approaching shortwave upper level trough and weak surface cold front will reach the Bay Area late this evening. This will bring a return of light rain to the North Bay and portions of the East Bay and San Francisco/San Mateo Peninsula. As of 12PM this afternoon, KMUX has been transitioned back into precipitation mode with the first echoes showing up over the outer coastal waters. Folks across the North Bay will start to see some light rain/drizzle this evening. Light rain will take longer to extend into the rest of the Bay Area with the East Bay and San Francisco/San Mateo Peninsula not seeing any rain until the overnight hours. Precipitation totals increased slightly with this afternoon`s forecast package compared to the overnight package. The highest totals are in the North Bay coastal mountains where up to 0.50" of rain are possible. Across the rest of the North Bay rainfall totals will be between 0.15-0.25" and up to 0.10" are possible across the East Bay and San Francisco/San Mateo Peninsula. The HRRR is in agreement with slightly higher precipitation totals from this cold frontal passage and shows a few showers developing farther south over the Monterey Peninsula. This is mostly worth noting since the NBM does not show showers extending that far south. If an isolated shower or two does develop along the Central Coast, accumulations will be minimal with a trace up to a few hundredths of an inch possible. Winds across the higher elevations will increase slightly as cold frontal passage occurs with gusts peaking around 25 mph. Rain showers clear out by 10/11AM on Wednesday with skies gradually clearing through Wednesday afternoon. Morning temperatures will be slightly warmer, in the low to mid 40s, while afternoon temperatures warm into the 60s. && .LONG TERM... Issued at 136 PM PST Tue Jan 27 2026 (Wednesday night through next Monday) Upper level ridging and dry conditions return by late Wednesday and continue through remainder of the week. The rest of the week will follow a similar trend as last week with chilly mornings and warm afternoons. Most locations will stay in the 60s during the day but the warmest interior locations (e.g. Salinas Valley and interior Central Coast) will reach the low to mid 70s. Long range guidance is showing the potential for an upper level trough to reach the West Coast late weekend into early next week. This will both cool temperatures down and bring a slight potential for rain back to the forecast. Ensemble guidance does show about half of the models indicating a few tenths of an inch of rain while the other half show no rain at all. Rain is most likely across the North Bay with chances decreasing the farther south you go. At this moment it remains possible we will see at least some rain towards the end of the long term forecast but confidence is mixed. Looking way out into the future - ensemble guidance is trying to produce some precipitation throughout the first part of February but no clear consensus currently exists. With the upcoming week shaping up to be warm and sunny, beachgoers should exercise caution. A Beach Hazards Statement is in effect from 9PM Wednesday to 9AM Friday. There will be an increased risk of sneaker waves and rip currents along the entire Pacific Coastline from Sonoma County to Monterey County. For more details see the Beaches Section below. && .AVIATION... (18Z TAFS) Issued at 1006 AM PST Tue Jan 27 2026 Mostly VFR conditions across the region at this hour. As a weak frontal boundary approaches the region look for conditions to deteriorate around mid afternoon across the North Bay and then late this evening and overnight across the Bay Area terminals. At this time, mostly MVFR conditions are expected over this region with fog returning early Wednesday morning at STS and LVK. Looking less likely MRY and SNS will receive anything more than VCSH and brief MVFR conditions this evening and into early Wednesday morning. VFR conditions are expected by Wednesday afternoon in wake of the frontal passage. Vicinity of SFO...VFR conditions will prevail through around 03Z Wednesday when conditions become more likely to reduce to MVFR as rain showers move across the region. A greater probability will be in the 06-09Z Wednesday timeframe for MVFR (temporary IFR if and when RA is present) as the main rain band is forecast to move across the terminals. MVFR will persist through about 18Z Wednesday before improving to VFR as skies clear in wake of the passing frontal boundary. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...Mostly VFR through the TAF period. Drainage winds (southeasterly) once again at SNS will become onshore by this afternoon. A weakening frontal boundary will approach late this evening increasing the probability for MVFR conditions. However, confidence is only moderate at this time. There is greater probability for VFR conditions by 18Z Wednesday. && .MARINE... (Today through Sunday) Issued at 850 AM PST Tue Jan 27 2026 Light to moderate southerly flow will prevail over most of the waters as a weak cold front approaches from the west today through early Wednesday morning. This will bring light rain to the northern coastal waters through Wednesday morning. Winds will be moderate to breezy north of Point Reyes with locally hazardous conditions for small craft. Winds diminish on Wednesday and switch to northerly that night. Moderate seas will prevail through Tuesday, but build rough to very rough Wednesday night. && .BEACHES... Issued at 359 AM PST Tue Jan 27 2026 Long period swells with low wave heights begin to arrive on Wednesday, but wave heights begin to increase that night while periods stay long leading to hazardous conditions. A Beach Hazards Statement has been issued from 09 PM Wednesday through 09 AM Friday. Significant wave heights look to range from 14 to 19 feet. The main threat will be from sneaker waves and rip currents. Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and NEVER turn your back on the ocean. && .MTR WATCHES/WARNINGS/ADVISORIES...

Conditions turn warmer and wetter with midweek system. && .DISCUSSION... Tonight through Friday: Through the next few hours, skies will see stratus over the area transition to overcast skies as a system moves in tonight. Tonight through Friday, a series of shortwaves will move across Washington and Idaho, ushering in moistening and warming air. PWATs with these shortwaves will rise to 100-130 percent of normal on Wednesday, drop briefly on Wednesday evening, and then surge to 150-200 percent of normal by Thursday. This influx of warm air over top of the cold air currently in place will result in a mix of precipitation types throughout the forecast area through Thursday evening. By Friday, temperatures will have warmed enough to result in mountain snow and lowland rain. The most impactful part of this mix of precipitation is a 20-30 percent chance of freezing rain throughout much of the basin and Spokane/Coeur d`Alene areas tomorrow and Thursday morning. This has the potential to cause minor to moderate impacts to the morning commute. People should be prepared to give themselves more time to get to their destination both mornings. There will be a brief break in this wintry mix before another wave moves in Thursday. By Thursday evening, as warmer air continues moving in, snow levels will rise enough to bring mostly rain to the lowlands and snow to the mountains, which will continue through Friday evening. While precipitation totals will be light, this is the first time in a couple weeks that the forecast area has a chance at measurable precipitation. There is a widespread 20 percent chance at seeing a wetting rain (0.10 inches) through Friday. For snow, Stevens Pass has an 80 percent chance of seeing four inches or more, and Lookout Pass has a 50 percent chance of two inches or more. Saturday through Tuesday: By Saturday, temperatures will have warmed into the mid 40s for much of the area. Clusters overwhelmingly show higher heights and warmer temperatures through the forecast area through the weekend. Ridging will strengthen through Saturday night before another weak shortwave moves in Sunday into Monday. Despite the influx of warm and moist air keeping PWATs above 100 percent of normal, only short periods of light lowland rain and mountain snow with little to no accumulation are expected through Tuesday. In line with the clusters, the CPC`s 6-10 and 8-14 Day Outlooks indicate increased chances of above normal temperatures and below normal precipitation. /AS && .AVIATION... 00Z TAFs: Light stratus and VFR conditions will prevail through around 10Z, which is when overcast skies will fill in ahead of the incoming system. There is decent agreement on precipitation moving through around 12Z and bringing ceilings down to MVFR/IFR. This precipitation will be a wintry mix, with ensembles favoring mostly snow (50 to 60 percent chance) at GEG, SFF, and COE to begin with, with COE experiencing snow a few hours longer than GEG and SFF, through 21Z. However, there is a 10-25 percent chance of mixed precipitation including freezing rain at GEG and COE from 12-14Z. These chances do not meet thresholds of being included in the TAF, but worth noting here due to potential impacts should chances increase, which we`ll keep a close eye on. Chances for freezing rain and more mixed precipitation are higher across PUW, with a 20-30 percent chance of freezing rain from 12-14Z before transitioning to rain and snow. LWS has a 90 percent chance of rain throughout the period. Precipitation amounts overall will be very light, with a few hundredths of an inch expected for accumulations. Another wave will begin moving in around 21Z, bringing precipitation to EAT and moving through the rest of the TAF sites during the next period. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence for VFR conditions expected through 10z. Timing of light precipitation reaching GEG, SFF, COE, PUW, LWS is still uncertain, though models are circling arrival around 12Z. Timing may need to be adjusted in future forecasts. Biggest confidence issues lie with precipitation type. While there is a 50-60 percent chance of GEG and COE starting as snow, there is a 10-25 percent chance each of rain and freezing rain. Alternate scenario with biggest impacts for GEG and COE would be these chances increasing and a light glaze of freezing rain occurring at these sites. Will monitor closely. Chances of freezing rain at PUW are more likely, and chances of rain/snow are nearly equal, but still moderate confidence at best. High confidence in rain at LWS. High confidence in VFR skies for MWH. High confidence in VFR skies for EAT until right near the end of the TAF period, where ensembles show ceilings dropping to MVFR. Moderate confidence in another wave moving in around 21Z, bringing snow to EAT before the next TAF period starts. /AS ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports,please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard && .Preliminary Point Temps/PoPs...

607 FXUS66 KPDT 272256 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 256 PM PST Tue Jan 27 2026 .DISCUSSION...Through this Evening: Upper level ridging over the PacNW continues to push east this afternoon, with mid to upper level cloud cover starting to spread northeast. There has been a few breaks in the clouds today, allowing some areas of central OR, Columbia Basin, and adjacent valleys to warm into the upper 30s to mid 40s. The remainder of the lower elevations have remained cool through this afternoon, owing to cloud cover aloft and haze near the surface, but have managed to warm above freezing. Not expecting much change in these temperature trends through the remainder of the daylight hours, as the cold pool impacting most of the region will result in temperatures quickly dropping to or below freezing through this evening. Tonight through Friday Evening: A series of shortwave troughs with attendant surface fronts will impact the forecast area starting tonight, with precipitation chances persisting at least in the mountains through Friday evening. The first of these shortwaves will lift northeast across the PacNW tonight through Wednesday morning, bringing the highest precipitation chances to the Cascade crest, Wallowas, and the Northern Blues through mid morning Wednesday. While the mountains will see light to moderate snow accumulations, the main precipitation concerns will revolve around a wintry mix in the lower elevations, specifically the potential for light freezing rain, as forecast models indicate a warm tongue extending across portions of the lower elevations. Confidence is moderate (50-75%) that pockets of central OR, the OR Columbia Basin, and adjacent Blue mountain foothills will see light freezing rain mix with rain, while a mix of snow and freezing rain is favored in the WA Columbia Basin and adjacent valleys. Snow accumulations in the aforementioned areas will amount to a dusting, while freezing rain accumulations across all the lower elevations will be under 0.05". That said, global and hires ensembles are in disagreement in impacted locations and accumulations, owing to poor handling of the persistent surface cold air pool, cloud cover aloft, and strength of the incoming front/shortwave. As such, this has resulted in low confidence (15-20%) in widespread freezing rain impacts. Light snow will continue across the Cascade crest and upper east slopes through Wednesday, with chances increasing again Wednesday night through Thursday as the next shortwave impacts the region. This next system is expected to have better moisture support, which translates to higher chances of lower elevation precipitation. Ensemble and NBM guidance is mostly in favor of mostly rain in the lower elevations with pockets of freezing rain along the lower portions of the Cascade east slope valleys. That said, the coldest ensemble members (mostly made up of the Canadian ensemble suite) keep the cold air pool in place across the lower elevations, resulting in more widespread freezing rain chances Wednesday night. While a majority of models bring warmer conditions, they have also continued to handle the cold pool poorly over the past few weeks, so forecaster confidence in precipitation type is low-mod (15-35%) for Wednesday night. Confidence in either solution will grow tomorrow depending on how temperatures trends shake out in the lower elevations. A ridge will briefly amplify over the region Thursday, but flatten as the last of the series of shortwaves slides across the PacNW Thursday night. Overall, guidance is in favor of warming conditions across much of the PacNW, with snow levels rising to above 5.5kft to 6kft Thursday night. That said, this last system will have a weak moisture plume that will result in the best precipitation chances across the Cascade crest with a trace at best east of the crest. By Friday evening, upper level ridging will redevelop over the PacNW, resulting in drying conditions. Friday Night through Monday: Ensemble guidance in good agreement of starting the weekend off with dry and mild conditions across the forecast area as an upper ridge parks across the region through Sunday morning. By Sunday afternoon, a shortwave will arrive to the PacNW and lift northeast through Monday, bringing with it a chance of light precipitation across the mountains and lower elevations of the forecast area(confidence 30-60%). Lawhorn/82 && .AVIATION...00Z TAFs...VFR conditions continues through the remaining TAF period for most sites. Even with limited moisture and the lasting colder air, light freezing rain is potential for KPDT/KYKM/KALW/KPSC (30% probability) tonight through Wednesday morning. That said, this led us to issuing an Airport Weather Advisory for KPDT. Low confidence (<30%) for an Airport Weather Warning for KPSC at this time, but will monitor for potential freezing rain. VSBY for KALW has improved, but now with haze lingering until later on today. Low cloud decks will continue across KALW as well into this late evening, though may return Wednesday morning. Guidance is also hinting fog later this evening for KALW, but left it out since confidence level is low given the upcoming system. However, it does depend on the strength on the system. Winds will remain less than 10kts. Feaster/97 && .PRELIMINARY POINT TEMPS/POPS...

244 FXUS65 KREV 272038 AFDREV Area Forecast Discussion National Weather Service Reno NV 1238 PM PST Tue Jan 27 2026 .KEY MESSAGES... * A weak weather system may bring chances for light snow showers, mainly along the Sierra Crest tonight into Wednesday morning. * Dry conditions continue Wednesday onward with high pressure returning to the area. * A slow, gradual warming trend into this weekend will bring above average temperatures by Saturday. && .DISCUSSION... A shortwave trough bringing a quick round of snow showers is still on track to move in the Sierra and NE CA. Peak precip probabilities early Wednesday morning will be around 40-50% for Surprise Valley, Plumas County, and western Lassen County, down to the western slopes of Tahoe. Lesser chances of up to 30% will be seen for Alpine County up through Tahoe and through the eastern portions of Lassen County. Some areas out in Pershing and northern Washoe counties also have a 30% chance to see a light snow shower. Max QPF values will range from 0.10-0.20" for this mini storm and since snow levels are going to hang around 5000 feet or below, snow amounts for the highest Sierra peaks look to be around a trace from Alpine County northward, with only 1-2 inches possible in the highest terrain in western Lassen over to Pershing County. With snow levels that low, be aware that the morning commute Wednesday morning may be slick and icy across Sierra passes, especially Donner. Southwest winds won`t pose much of an issue either, only Sierra ridges may get up to 60-70 mph Wednesday morning. Once this system moves out by midday Wednesday, the clouds will dissipate and we`ll return to our usual dry and calm conditions. Wednesday onward, we`ll see high pressure move in again and keep us dry and sunny through this weekend. High pressure will move in late this week, increasing temperatures to near 60 in lower valleys and upwards of 55 in Sierra communities by Saturday. This warm up will be around 10 degrees above normal for this time of year. Mornings will still be pretty chilly, though. Morning temps this weekend will be around 30-35 for lower valleys and 25-30 for Sierra valleys. After this week, our next best chance for precip looks to be around the 1st or 2nd of February, but confidence remains low this far out. -Justin && .AVIATION... VFR conditions and light winds will be the main story through about 06Z tonight. A brief wave of light snow showers will move in tonight and exit tomorrow morning around 14-15Z. KTRK/KTVL/KSVE have a 40- 50% chance to see snow showers, with accumulations up to 1". MVFR conditions are possible for the Sierra terminals, but are unlikely due to the intensity of the showers. FL100 winds tonight will peak around 09Z at 40-45KT out of the southwest, although Sierra ridges could see gusts up to 60KT. Expect LLWS and turbulence over the Sierra and Sierra Front tonight through about 15Z. Dry conditions and light winds are expected the rest of Wednesday. -Justin && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$

435 FXUS66 KSTO 272127 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 127 PM PST Tue Jan 27 2026 .KEY MESSAGES... - A quick-moving system will bring light rain and snow showers later this afternoon through early Wednesday morning, mainly from HWY 50 northward. Little to no impacts expected. - Dry weather with patchy fog in the Valley and lower foothills late week into the weekend. - Slight chances for very light showers over the Coast Range and Shasta County mountains on Sunday, with little to no impacts. && .DISCUSSION... ...Today through Wednesday Morning... Chances for light rain and snow showers return to the area later this afternoon and continue into early Wednesday morning, mainly from Highway 50 northward as a weak trough moves across the region. Forecast precipitation amounts are expected to remain light, with little to no impacts. WPC precipitation guidance indicates amounts ranging from less than 0.1 to around 0.40 inches in the Delta and the Sacramento Valley, with 0.10 to 0.50 inches over the mountains (locally higher amounts up to 0.75"+). High elevation snow showers are also expected above 5500-6000 feet, with amounts generally ranging from less than 1 inch to around 3 inches, except for locally higher amounts near Lassen Park. Use caution while driving as roads might be slick. For tonight into Wednesday morning, high resolution ensemble guidance indicates a 25 to 50 percent chance of visibilities less than 1/2 mile across portions of the central/southern Sacramento Valley and the northern San Joaquin Valley. However, cloud cover may limit dense fog development. ...Wednesday Afternoon through the Weekend... Upper level ridging builds back in behind the departing system, with dry weather prevailing across the area late week into the weekend. Morning fog potential also returns to the Valley and lower foothills during this timeframe. Be sure to slow down and use low- beam headlights if fog is encountered while driving. Ensemble guidance then indicates the potential for another weak system to approach the Pacific Northwest by the weekend with some additional chances for very light precipitation over the mountains north of Interstate 80 by Sunday. Little to no impacts are expected. && .AVIATION... General VFR conditions for much of interior NorCal except for patchy MVFR/IFR conditions in fog and mist in the northern San Joaquin Valley from 06Z-18Z Wednesday. Valley surface winds mostly below 10 kts through the forecast period, with portions of the central Sacramento Valley seeing gusts up to 20 kts. Foothill and mountain gusts up to 25 kts through 09z Wednesday. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$

164 FXUS65 KMSO 272039 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 139 PM MST Tue Jan 27 2026 .DISCUSSION... KEY MESSAGES: - Light snowfall Wednesday, especially through north central Idaho. - Pockets of light freezing rain in valleys and snow at pass level are possible Thursday into Friday, especially in the mornings. - Mild temperatures expected for the beginning of February. High pressure over western Montana and north central Idaho will begin to break down tonight in advance of a weak weather system. Showers will spread first into north central Idaho Wednesday morning, then into western Montana by afternoon. Enough forcing with this system exists to produce some light snow accumulations through primarily north central Idaho down to roughly 2500 feet, impacting portions of the Highway 12 corridor. There is a 60 to 80 percent chance of seeing at least an inch of snow for locations such as Lolo Pass, Lookout Pass and in the higher terrain, however lower elevations most likely will see half of an inch or less. Though generally light, slick spots are a possibility during the morning commute. Although weak high pressure begins to build back into the region Thursday into Friday, additional waves of moisture are anticipated to move through the ridge, bringing periods of showers to northwest Montana and north central Idaho in particular. Snow levels will likely begin to rise during this timeframe, especially Thursday night into Friday. As this occurs a period of mixed precipitation (including light freezing rain) will be possible in valleys. This overall looks like a light event, but it only takes a tiny bit of ice to make things slick, especially over bridges/overpasses. Showers will be decreasing on Saturday and many valleys will be much warmer than average for this time of year! High pressure looks to be the dominant feature over the western US for much of next week, which is well represented by virtually all ensemble model solutions through at least day 9 (Feb 5th). Mild conditions are anticipated, though valley inversions may strengthen with the ridge in the later part of next week. Forecast models do show a weak disturbance moving through the ridge on Monday, which will briefly increase cloud cover and bring some light snow to mountain passes. && .AVIATION...VFR conditions with dry weather is expected through tonight. Despite a weak ridge of high pressure, increasing clod cover and relatively dry conditions in the lower levels should keep fog formation at bay. A weak wave will bring light snowfall across north-central Idaho generally after 28/1200Z, then transition to mountain snow showers by the afternoon across the remainder of the region. Increasing winds near ridge top levels to around 35kts may lead to some increased mechanical turbulence, particularly after 28/1800z. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None.

721 FXUS65 KBOI 272031 AFDBOI Area Forecast Discussion National Weather Service Boise ID 131 PM MST Tue Jan 27 2026 .SHORT TERM...Tonight through Thursday night...Areas of mist and slightly reduced visibility are occurring in the Treasure Valley this afternoon thanks to limited mixing and light winds. However, this quiet pattern will get a little jolt of excitement tomorrow thanks to an upper level trough moving into the PacNW, bringing a quick hitting cold front to the region. This will bring breezy westerly winds, especially in the Lower Snake Plain to the Magic Valley and on ridgetops. Snow will be the dominant precipitation type in the region with some light showers, with snow levels gradually increasing as the day progresses from valley floors to 3500-4500 feet. Pockets of freezing rain will occur in the Lower Treasure Valley, generally south of Ontario- Caldwell. Snow amounts across the region will generally be a dusting to 1 inch, with up to 2 inches in higher elevations and on mountain tops. Precipitation will end by the mid afternoon, with winds staying elevated in southern portions of our CWA through the day. Another system will move in over top of the rebuilding ridge on Thursday, with light snow showers over Baker County and the West Central/Boise Mountains. Other than the far northern regions, Thursday will generally be dry with cold temperatures lingering in area valleys. .LONG TERM...Friday through Tuesday...A weak shortwave trough moving westward over the top of the persistent upper level ridge will bring a 20 to 30 percent chance of precipitation to the area on Friday before the ridge restrengthens on Saturday and Sunday. Another shortwave will dent the ridge again on Monday and Tuesday bringing another chance of light precipitation forecast area. Temperatures will be near to slightly above seasonal normals for this time of year with a slow warming tend. Snow levels range between 4500 and 5500 feet, so the precipitation type will likely be snow in the mountains and rain in the valleys. For now, there appears to be enough flow to keep the atmosphere from getting too stagnant or foggy. However, the addition of some moisture from the weak systems mentioned earlier in the discussion will increase the chance for valley fog later in the extended forecast period. && .AVIATION...VFR through this evening.

Updated at 1201 PM PST Tue Jan 27 2026 * Light snow likely in Northern Nevada tonight and Wednesday * Warming trend Thursday through Saturday * Near record warmth in parts of Northern and Central Nevada Sunday afternoon && .DISCUSSION... (This afternoon through Monday) WEATHER PATTERN OVERVIEW: An Eastern Pacific trough of low pressure will make landfall along the west coast of the United States this afternoon. The southern extent of this trough of low pressure will progress eastward across Northern Nevada tonight and Wednesday, resulting in the likelihood of light snow. Snow chances will be highest in Northern Elko County Wednesday morning. Here are probabilities of 0.1 inches of snow for select locations in Northern Nevada tonight and Wednesday: Jarbidge - 92% Owyhee - 84% Wildhorse - 78% Jackpot - 75% McDermitt - 70% Denio - 67% Lamoille - 57% Spring Creek - 50% Orovada - 49% Elko - 41% A ridge of high pressure will build northward over the service area Thursday through Saturday. A warming trend is expected Thursday through Saturday. By Saturday afternoon, high temperatures will be around fifteen degrees above normal for this time of year. Near record warmth is expected in Eureka Sunday afternoon. The current record for maximum temperature measured in Eureka on February 1st is 58 degrees, initially established in 2003 and last recorded in 2020. Temperature records at Eureka date back to 1963. A trough of low pressure will move eastward across the Silver State Monday, resulting in a chance of precipitation. FORECAST CONFIDENCE & DEVIATIONS: High forecast confidence regarding the likelihood of light snow in Northern Nevada tonight and Wednesday. High forecast confidence in a warming trend Thursday through Saturday. Moderate forecast confidence in near record warmth in parts of Northern and Central Nevada Sunday afternoon. No deviations from the NBM model output. && .AVIATION... VFR conditions will prevail at all terminals through at least the next 24 hours.
