077 FXUS66 KSEW 221819 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 1119 AM PDT Fri May 22 2026 .SYNOPSIS... Weak high pressure remains in place today, flattening and becoming more zonal over the weekend. Onshore flow will increase over the next several days. A system arriving on Memorial Day will bring widespread rain and cooler temperatures to the region. The rest of the front will move through on Tuesday, keeping showers in the forecast. Weak ridging is possible through the second half of the week. && .SHORT TERM /TODAY THROUGH SUNDAY/... Satellite imagery early this morning shows the stratus along the coast, remaining generally clear around Puget Sound. Temperatures are in the low to mid 50s. Weak high pressure aloft will transition to more zonal, onshore flow through the weekend. This will bring in morning marine stratus clouds that reach the interior by Saturday and Sunday. Afternoon sun is expected as the stratus erodes. Expect highs in the upper 60s to low 70s. The onshore flow will also strengthen the westerly winds through the Strait of Juan de Fuca over the weekend. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... The zonal flow will open the door to the next system arriving late Sunday night into Monday. This one will bring about more widespread rain to western Washington and temperatures that are unlikely to get much warmer than the low 60s by Monday. While not a final forecast, indications of what the QPF could look like at this point suggest around a quarter to three tenths of an inch of rain in the lowlands and one to one and a half inches of rain in the Cascades and Olympics from Sunday afternoon through Tuesday afternoon. After this system moves through, temperatures will only slightly increase into the upper 60s. Beyond Wednesday, there is uncertainty as to whether a trough or ridge rebuilds. The ensembles are split with no real consensus at this point and looks to generally remain dry in the extended forecast. 21 && .AVIATION... West-northwest flow aloft through today with weak ridging over the area. Onshore flow continues at the surface. VFR conditions for the interior early this morning, with LIFR/IFR along the coast. Visibility may towards less than 1 SM for the immediate coast at times this morning. Stratus will then clear late morning into midday with VFR conditions for the afternoon. Light winds this morning will increase from the N/NW this afternoon. KSEA...VFR conditions through the period. Stratus expected to remain well SW of the terminal this morning, with less than a 10% chance of IFR cigs this morning. Mainly NE winds this morning will increase from the NW this afternoon ranging 5 to 10 kts. && .MARINE... Onshore flow continues into the weekend with high pressure offshore and lower pressure inland. Northwest winds will remain over the Coastal Waters through the weekend. West winds increase through the Strait of Juan de Fuca this evening, resulting in SCA gusts to 25 kts into tonight. A stronger west push through the Strait of Juan de Fuca is expected Saturday night, with the potential for localized gales through the Strait during this period. At this time, the probabilities for gale force wind gusts peaks around 75% for the central and eastern Strait. Winds will then ease once again on Sunday. A weather system traverses the area on Monday, bringing widespread SCA wind gusts to much of the area waters. Seas will mainly remain 5 to 9 feet through this weekend, with the largest and steepest waves over the offshore waters. Dominant periods will be around 8 to 9 seconds through Sunday. Waves increase to 10 to 13 feet Monday into Tuesday with the next weather system. JD && .HYDROLOGY...

996 FXUS66 KPQR 221955 AFDPQR Area Forecast Discussion National Weather Service Portland OR 1255 PM PDT Fri May 22 2026 .SYNOPSIS...High pressure will keep the region dry and warm through the weekend, though temperatures ease down a bit after today. Clouds will increase late Sunday/early Monday ahead of a frontal system, with rain and cooler temperatures returning for the start of the week. Breezy conditions are possible with the front, which could affect outdoor Memorial Day plans. For the remainder of next week, cooler and drier conditions are expected through the remainder of the week. && .SHORT TERM...Today through Sunday Night...High pressure remains anchored over the region resulting in generally clear skies and warm, daytime highs. The upper level high is expected to remain the dominant synoptic feature for the region through at least Sunday evening. Afterwards, a pattern change is expected as a broad area of low pressure pushes southeastward out of the Gulf of Alaska. For the remainder of the week and into the weekend, expect warm and dry conditions for most of the CWA. Persistent onshore flow will help to mitigate temperatures. Inland highs through Sunday will be in the upper 70s to lower 80s, along the coast temperatures will be about 15-20 degrees cooler with highs in the low 60s to low 70s, as marine stratus is expected to linger as onshore flow persists along with upwelling from the Pacific Ocean. The Cascades and Cascade Foothills look to "split the difference" between the Coast and the Willamette Valley as daytime highs are expected to be in the mid 60s to mid 70s through Sunday. /42 .LONG TERM...Monday through Friday...Looking towards the start of next week, Memorial Day looks to be cool and wet as the Alaskan Low mentioned above moves from the northwest to the southeast. This system looks to bring anywhere from 0.20" to 1.00" within a 24 hour period (5AM Mon-5AM Tues). Generally speaking, the probabilities for 24 hour rainfall totals of at least 0.25" across are 50% or higher, with the highest probabilities along the Coast and within the Coast Range and Cascades. Looking at the probabilities for 0.50" or more the chances sharply decrease with the Willamette Valley dropping to 10-25% chance, while the Coast, Coast Range and Cascades drop to around 50-90% chance. As for the probabilities for 1.00" or more, from Lincoln City, OR towards the Long Beach Peninsula, there is a 35-55% chance for 24 hour totals to reach 1.00" or more. The other factor to consider for Memorial Day, is the potential of thunderstorms. CAMs are showing the potential for thunderstorms on Monday with CAPE values ranging from 70-300 J/kg. Now, the higher CAPE values are coming from the Canadian Model, which have a tendency to run "hot". Still, this is a semi-favorable patter which does warrant a 15-20% chance for thunderstorms on Monday. The Alaskan Low, will also usher in cooler temperatures across the CWA with daytime highs on Monday in the mid 50s to mid 60s. In addition to the rain, Monday may turn breezy as the front moves through. Currently, there is a 70-90% chance for gusts exceeding 25 mph across the entire CWA. A 30-65% chance of gusts exceeding 30 mph for inland locations with 60-80% chance along the coast. Focusing in on 35 mph gusts, inland locations have a 5-15% chance, while coastal locations have a 20-40% chance. These speeds are not currently suggestive of advisory- level winds, but could create minor issues for unsecured tents, canopies or other light outdoor gear. As the upper level continues to march southeastward on Tuesday, afternoon thunderstorms return to the forecast along with light precipitation totals around 0.05-0.15". While the bulk of the precipitation looks to occur on Monday, some ensembles are slowing the system down which could push the precipitation more into Tuesday. As for the middle and latter parts of next week, cooler and drier conditions are expected to prevail as weak high pressure/zonal flow looks to develop. Overall, expect cooler conditions through the majority of next week, with rain on Monday and Tuesday followed by drier conditions prevailing for the middle and latter parts of next week. /42 On a slightly personal note, with Monday being Memorial Day, it is time to remember those who served that are no longer with us. I want to remind everyone that if you are a fellow veteran or know a veteran that needs help, you can always call the VA Crisis Line by dialing 988 and pressing 1 or text 838255 24/7/365. We must take care of and look out those who stood besides us, who came before us and who will follow in our footsteps. Semper Fi. /42 && .AVIATION...Satellite imagery and terminal observations as of early Friday afternoon depicts clear skies with VFR conditions across the Willamette Valley while marine stratus lingers along the coast bringing IFR conditions. There is high confidence that marine stratus will hold along the coast throughout the day, though there could be intermittent breaks to VFR at KONP. Meanwhile, high pressure will maintain VFR conditions with clear skies continue through this evening for inland terminals. Northerly to northwesterly winds generally around 5-10 kt for most terminals this afternoon, except breezier at KONP with gusts up to 20-25 kt. Tonight, winds weaken as pressure gradients ease and LIFR/IFR conditions return along the coast as marine stratus re- builds. Across the Willamette Valley, increased moisture will support stratus development tomorrow morning with a 30-50% chance for MVFR CIGs at any given hour between 12-17z Sat. Morning stratus should break out with daytime heating after 17-18z Sat. KPDX AND APPROACHES...VFR conditions through the majority of the TAF period. Moister conditions will support a return of low-end VFR CIGs (less than 4 kft) after 12z Sat. There is a 20-40% chance for MVFR CIGs at any given hour between 12-17z Sat for KPDX. Northwesterly winds around 5-8 kt today, weakening below 5 kt tonight. -10 && .MARINE...High pressure offshore will maintain breezy northerly winds through Saturday. The strongest winds are expected during the afternoon and evening periods as the surface thermal trough strengthens over the northern CA/southern OR coast. Small Craft Advisories for northerly wind gusts up to 25 kt remain in effect for the waters south of Cape Falcon through 5 AM Sunday, and through 11 PM Friday for the waters north of Cape Falcon and beyond 10 NM offshore. Seas 6 to 9 feet are expected across all waters through this weekend. The summer-like pattern is expected to break down Sunday night as a front approaches the waters. This system will return breezy southwesterly winds by early Monday morning and a westerly swell that will likely (>80% chance) build seas above 10 ft by Monday afternoon. -10 && .PQR WATCHES/WARNINGS/ADVISORIES...

070 FXUS66 KMFR 221737 AFDMFR Area Forecast Discussion National Weather Service Medford OR 1037 AM PDT Fri May 22 2026 ...New Aviation Section... .AVIATION (18Z TAFs)... Conditions along the coast should improve to a SCT deck this afternoon for KOTH, but expecting IFR conditions are likely (60%) to return tonight with another marine layer push. There is some uncertainty to how far inland this push will be, and there is a chance (30%) we could see MVFR conditions at KRBG, but confidence was not high enough to include this mention at this time. Instead, hinted at this possibility with a SCT deck around 1000 feet. Otherwise, expecting plenty of sunshine for inland sites with typical diurnal breezes across the region. -Guerrero && .PREV DISCUSSION... /Issued 605 AM PDT Fri May 22 2026/ SYNOPSIS... Hot and dry weather continues through the weekend. A cold front will bring some rain to the region during the afternoon of Memorial Day. The threat of showers will persist through much of next week as a low hovers around the region. DISCUSSION... Temperatures will remain high today, even with some onshore flow developing later in the evening as a thermal trough moves further inland. Even with a more zonal flow pattern developing into the weekend, temperatures will remain elevated with highs in the upper 80`s here in Medford on Sunday. Some embedded shortwaves in this flow will bring a very low chance of showers Saturday afternoon. We should also see a fair amount of cloud cover along the coast between Friday and Sunday as this thermal trough retreats farther inland. We usually see plenty of coastal stratus shoot up the coast when these thermal troughs move inland and the NBM does have this in the forecast. Not a huge impact, although temperatures could be cooler along the coast this weekend. Things begin to change up on Monday as a trough in the Pacific approaches the Oregon coast. Ensembles are in really good agreement with the timing of the cold front moving onshore during the afternoon and evening of Memorial Day. It looks like the cold front initially moves onshore between 18Z and 21Z on Monday with the probability of precipitation peaking between 0Z and 6Z with some grid points showing PoPs around 90%. Overall, early Monday should stay dry, although plan for some lighter rain in the afternoon hours. Looking at the forecast soundings, thunderstorms look unlikely as there isn`t much instability and most of it is between the 0C to -10C layer, so not much charge generation in the clouds. As this cold front and trough approach the region, wind speeds near the surface will also increase. 700mb winds are around 30 to 35 knots during peak mixing, so still short of wind advisory thresholds east of the Cascades. Overall, pretty low impact weather unless one has outdoor activities on Memorial Day afternoon. With more cloud cover on Monday, temperatures will trend down notably compared to what we`ll see this weekend. Those temperatures will trend even lower by Tuesday once the colder air funnels into the region. This low will likely become cutoff and stall out around south central Oregon/north western Nevada/northeastern California. The end result should be sporadic cloud cover through the week and the continued chance of some showers or perhaps some thunderstorms. The probabilities are highest on Tuesday, although they generally lower through the week as there are questions about moisture and how this low evolves through the week. Overall, the weather definitely becomes more active next week, although the impacts are not extreme. We do have some fire weather threats noted in the discussion below on Monday, especially around Lake County. -Smith AVIATION...22/12Z TAFs...Along the coast, areas of IFR ceilings will continue through this morning near Coos and Douglas Counties. Offshore flow will keep the coast clear near Curry County this morning. More IFR coastal stratus is anticipated along the coast later tonight. Inland, expect VFR levels with clear skies through the TAF period. MARINE...Updated 300 AM Friday, May 22, 2026...Conditions will remain hazardous to smaller crafts through Friday night due to gusty north winds and high and steep seas. The thermal trough will weaken by Sunday and a cold front will move through the waters by Monday. This cold front will bring some gusty south winds and a high and steep seas to the waters on Monday night into Tuesday. These seas will be hazardous to smaller crafts as wave heights increase up to 13 to 15 feet. -Smith && .MFR WATCHES/WARNINGS/ADVISORIES... OR...CA...None.

728 FXUS66 KEKA 222100 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 200 PM PDT Fri May 22 2026 .SYNOPSIS...Coastal cloud cover kept temperatures mild this afternoon, meanwhile inland temperatures reached into the 90`s. A cooling trend starts this weekend and continues into early next week. Isolated thunderstorms possible in Trinity County late afternoon/early evening. There is a chances of wetting rain for Del Norte and northern Humboldt counties Monday through Tuesday. Northerly winds will begin turning strong again by Monday afternoon, and likely remaining breezy through mid next week. && .KEY MESSAGES... - Chance (10-15%) of isolated mountain showers and thunderstorms across Trinity County, late this afternoon and early evening. - Gradual cooling trend and lighter winds this weekend and into early next week. - Coastal stratus will become more stubborn to scatter out through the weekend. - Light to locally moderate showers are forecast on Monday/Monday night, with lingering showers through Tuesday. - Breezy to gusty northwest winds returns next Tuesday. && .DISCUSSION...High pressure over the PACNW is starting to weaken, while a low amplitude shortwave trough develops over Northern California overnight. Coastal stratus and patchy fog around Humboldt Bay and along much of the immediate coast will likely return tonight and are expected to become more stubborn to scatter through the weekend. The aforementioned weak shortwave will bring a slight chances (10- 15%) of isolated thunderstorms for Trinity County later this afternoon and early evening, with the west-northwest flow keeping the cells over the eastern portion. Cooler temperatures are expected for this weekend and early next as the shortwave trough persist over the area and the flow aloft become more zonal. A lingering chance (below 10%) for convective activity may carry into Saturday afternoon for far northern Trinity County if the cap can break. A deeper trough will work farther south Monday. A late season, weak front off the low has been forecast to clip the area and deliver some light rainfall or drizzle to the northern portion of the region Monday and possibly Tuesday. With a slightly more southerly track modeled, chances for a wetting rainfall (over 0.1 inch) have increased to 30-50%; however, these types of systems usually under perform when arriving into such dry antecedent conditions. Ensemble spread is still quite high, ranging form nothing to 0.4 inches for Del Norte, and this is typical modeling for late season systems. The deep trough will progress SE through the Pacific Northwest/Great Basin region later Monday through Wednesday. With Northern Pacific high pressure strengthening against it, the northerly to westerly winds will once again begin turning strong by Monday afternoon. The strongest winds will initially be focused over the eastern portion of the area, through Trinity and Lake Counties. Chances for gusts over 35 mph are notably high for Lake County Monday afternoon and evening, at 60-75%. Wind gusts over 40 mph are also looking probable (40 to 50%) for the ridges and locations around Clearlake. On Tuesday, these strong northerlies expand westward over the coastal regions. Chances for wind gusts over 30 mph are pretty solid for the exposed coastal headlands Tuesday afternoon, at 40 to 60%. This pattern will not likely quickly breakdown through Wednesday, but chances for stronger gusts are much lower Thursday. /ZVS&JJW&EYS && .AVIATION...(18Z TAFs)...Stratus has partially eroded and lifted early this afternoon, bringing VFR conditions at all terminals. Stratus is likely to return again this afternoon and overnight. Models are pointing at a slightly deeper marine layer as high pressure weakens, but ceilings along the coast are still likely to be LIFR to IFR with occasional visibility reductions, especially near sunrise. Interior areas could see further stratus intrusion tonight as the marine layer deepens. KUKI has about a 40% chance of seeing at least MVFR ceilings overnight. JB && .MARINE...Strong near-gale to gale-force winds continue in the outer waters, especially north of Cape Mendocino. Nearshore winds remain much weaker, aside from around Cape Mendocino and Pt. St. George. Still, strong winds in the outer waters continue to generate steep to very steep, hazardous seas. Northerly winds diminish this weekend as the high pressure shifts eastward and the pressure gradient relaxes. Seas will also subside this weekend and into early next week, and are forecast to be below 5 feet across the waters by Sunday night. Monday, winds shift to west-northwest as a cold front from the Northeastern Pacific (NEPAC) moves through. Seas for Memorial Day will be relatively mild around 4-6ft expected. Winds shift to northerly and increase in the wake of the front Monday night through Tuesday. A NW swell around 7-11 feet at 12 seconds is expected to build in Tuesday. This NW swell is forecasted to be up to 14-16 feet at 12 seconds at its peak on Tuesday/Tuesday night. High confidence (80-100% chance) for gale- force gusts redeveloping on Tuesday for the southern waters. The chances for gale-force gusts increase to the northern waters Tuesday night/Wednesday. /ZVS&JB && .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS...

789 FXUS66 KMTR 221952 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1252 PM PDT Fri May 22 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1250 PM PDT Fri May 22 2026 - Diurnally driven onshore winds during the afternoon and early evening through early next week - Gradual cooling trend continues with seasonal temperatures for the upcoming weekend and cooler temperatures early next week && .SHORT TERM... Issued at 1250 PM PDT Fri May 22 2026 (This evening through Saturday) The marine layer deepen to ~1500 ft this morning and resulted in cooler conditions along the coast and adjacent valleys. May not have lowered temperature in these areas enough, however they are on a warming trend now the sun is out. Thus, expecting afternoon temperatures to warm into the upper 70s to middle 80s across the interior, lower 60s to lower 70s around the San Francisco bayshore, and upper 50s to middle 60s near the coast. Dry conditions persist this afternoon with elevations above 1500 ft are seeing 10%-30% humidity values. As the marine layer is forecast to remain steady, low clouds near the coast will spread further inland this evening and spread deeper into the valleys early Saturday morning. There is also the potential for coastal drizzle, yet the probability is not great enough to include in the official forecast grids. For Saturday afternoon, we are expecting slightly cooler temperatures than today as stratus will be slower to clear. This is also in response to more zonal for developing over the region. && .LONG TERM... Issued at 1250 PM PDT Fri May 22 2026 (Saturday night through next Thursday) Zonal flow will persist on Sunday, thus temperatures will be similar to those on Saturday as far as afternoon maximum temperatures go. During the late evening and overnight hours, cannot rule out coastal drizzle again Saturday night into Sunday morning. By late Monday and early Tuesday, a cold front associated with a deep upper level through is forecast to sweep across the region. This would result in drizzle and/or light rain as the front moves from north to south across the Bay Area and Central Coast. However, widespread rainfall is not expected and will be very light not amounting to much more than a few hundredths of an inch. In wake of the frontal passage, the marine layer may mix out and allow for coastal locations slightly warmer compared to this weekend. Winds are also forecast to strengthen over the coastal waters on Tuesday and Wednesday. From the previous forecaster: "Towards the later part of the week, the ensemble model runs begin to diverge as the evolution of the upper level low and incoming ridging becomes uncertain. Most runs lean towards a warming trend for that period, which is reflected in the current forecast, with a significant minority (around 30-40% of the runs) suggesting that some form of trough lingers through the period." && .AVIATION... (18Z TAFS) Issued at 1132 AM PDT Fri May 22 2026 Stratus is eroding from all non-coastal sites. HAF looks to keep CIGs through the day while the rest of the region sees VFR by the mid afternoon. Wind turn more moderate into the afternoon, but directions will be determined by more localized effects, rather than an overall flow. Winds reduce into the evening, allowing stratus to flow inland and causing IFR/MVFR CIGs to begin to form and push inland. LIFR CIGs and patches of fog will be possible in the near coastal sites as well as in the north bay terminals into Saturday morning. Cloud cover looks to erode into the late morning and early afternoon on Saturday for all but HAF. Vicinity of SFO...Moderate west winds arrive into the afternoon as stratus continues to retreat. Winds will reduce into the late night as scattered clouds arrive. Expect MVFR CIGs to form into early Saturday morning while winds shift more southwesterly. CIGs erode into the late morning ahead of moderate west winds returning into the afternoon. SFO Bridge Approach...Similar to SFO.

Dry conditions with above normal temperatures will continue through the weekend. Breezy winds are expected at times through the Cascade gaps and across the western Columbia Basin especially Saturday and Sunday. There is high confidence for cooler and unsettled conditions to return early next week. && .DISCUSSION... Today through Sunday: Friday starts the breakdown of the ridge. A trough will begin to extend south from the Gulf of Alaska. The period will remain precip free except for small chances (up to 15 percent) along the Canadian border on Friday afternoon. These areas also have a low chance of producing an isolated lightning strike. For the rest of the period, winds will be main concern. Friday afternoon has Southwest gusts into the 20s across the Basin. Saturday will have stronger gusts with a tighter pressure gradient. Gusts into the 30s expected through the Cascade valleys and Western Columbia Basin. Probabilities are at least 50 percent for these areas. Okanogan Valley has a 36 percent probability. Sunday sees the gusts weaken back into the 20s. Highs will be in the upper 70s and 80s. The winds, warm temperatures, and dry conditions will elevate quick fire spread concerns through the Memorial Weekend. Winds are not expected to be strong for dust concerns. But some localized areas near recently worked fields cant be ruled out. Overnight lows will be in the balmy in the upper 40s and 50s. Monday through Thursday: Ensembles have come into decent agreement on a decent Low moving through the Pacific Northwest for Monday and Tuesday. The system will start with gusty winds on Monday morning followed by showers and possible isolated thunderstorms for the afternoon. Winds will be highest across the Basin and through the Okanogan Valley. Speeds will be the upper teens to low 20s with gusts into the upper 20s and 30s. Probability of 40 or greater gusts is highest around Moses Lake and Othello with 20-40 percent. Precip amounts of a tenth or two are expected for Monday. Ensembles continue to struggle with the Monday highs. It continues a 10-15 degree spread of 25-75 percent probability. With increasing clouds through the morning, Monday highs will dip into the 70s. It could inhibit any surface based instability and keep thunderstorm potential to less than 10 percent. The Low will slowly slide east through Wednesday morning. The weather impacts will lessen through the period. Shower activity will mainly be over the higher terrain, Eastern Washington, and the Idaho Panhandle. There is a hint of wrap around showers for the Western Basin overnight Tuesday into Wednesday. Winds will be calmer with gusts into the teens. By Thursday, a broad ridge pattern begins to build off the coast as the Low exits the region. Highs will be coolest on Tuesday with a range of 60s. They will steadily climb Wednesday and Thursday back into the 70s and low 80s. Overnight lows will be mild with the cloud cover. Lows will remain in the 40s to low 50s. /JDC && .AVIATION... 18Z TAFs: VFR conditions with winds generally less than 10 knots are expected for the TAF sites for the next 24 hours. There is a small chance (10-25%) for showers and isolated thunderstorms across the northern mountains this afternoon and evening. The best chances are along and north of the Canadian border, including around Bonners Ferry and Metaline Falls. This will bring a risk of isolated lightning, small hail, and outflow winds up to 30 mph. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in VFR conditions. Low confidence in showers and thunderstorms across the northern mountains. ----------------------- 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...

999 FXUS66 KPDT 221748 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 1048 AM PDT Fri May 22 2026 .KEY MESSAGES... - Warm, dry conditions through the weekend - Breezy to windy through the Cascade gaps Saturday and Sunday - A low-pressure system and cold front are likely (80 percent confidence) to arrive Monday, but details are still uncertain && .DISCUSSION... Dry northwesterly flow aloft today will transition to zonal flow over the weekend, resulting in warm, dry conditions, with temperatures of around 5-10 degrees above normal for our population centers. Breezy to locally windy westerly winds are forecast Saturday through the Cascade gaps as cross-Cascade pressure gradients increase in magnitude to 6-10 mb between PDX and GEG per latest NWP guidance. Don`t have high confidence in the need for wind headlines, but NBM probabilities suggest localized areas with a 50-70 percent chance of reaching advisory-level wind gusts (45 mph or greater) through the eastern Columbia River Gorge, Kittitas Valley, the Simcoe Highlands, and wind-prone portions north-central Oregon. Surface pressure gradients are expected (80 percent confidence) to slacken by several millibars on Sunday, with breezy winds forecast through the same region as Saturday. Monday through the remainder of the week, uncertainty in forecast details becomes noteworthy as ensemble guidance suggests a low-pressure system with origins in the Gulf of Alaska will dive southeastward into the Pacific Northwest, resulting in breezy to windy conditions, cool temperatures, and precipitation chances region-wide (highest for the mountains). While all clusters of ensemble members show the low tracking into the Pacific Northwest by Monday, there are some differences in the depth of the closed low as it approaches the coast. Differences in timing of the low`s arrival also translate to some uncertainty in timing of the cold frontal passage; 00Z ensemble guidance takes the front from west to east across the forecast area sometime between late Monday morning and late Monday evening. Widespread breezy to windy conditions are forecast with the passage of the front. The ECMWF EFI is painting much of the forecast area with values of 0.6-0.9 for wind, and the NBM shows medium-high (50-90 percent) probabilities of advisory-level gusts across wind-prone portions of all of our non-mountain zones. By Tuesday, ensemble systems begin to diverge in their solutions regarding the track and evolution of the closed low. Roughly 40 percent of members show a deeper low centered over western Oregon while the remaining members have a slightly shallower low centered over central Oregon to central Washington. Differences really begin to grow by Wednesday as 13 percent of members show the low transitioning into an open wave while the remaining members keep a broad closed low over the Great Basin extending into the Pacific Northwest. Solutions continue to diverge Thursday with about 70 percent of members retaining the closed low somewhere over the Great Basin while the remaining members favor a progressive solution with either near-normal heights (16 percent of members) accompanied by cool temperatures or above- normal heights (15 percent of members) and warmer, dry conditions. Of the members that advertise a closed-low, roughly half show the low extending far enough north into the Pacific Northwest to result in cool, wet weather while the remaining members take it far enough south into the Great Basin to have warmer temperatures and mostly dry conditions for the Washington side of our forecast area. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...

258 FXUS65 KREV 221900 AFDREV Area Forecast Discussion National Weather Service Reno NV 1200 PM PDT Fri May 22 2026 .KEY MESSAGES... * Showers and thunderstorms expected each afternoon through the holiday weekend, posing impacts to outdoor activities. * Warmer than normal temperatures persist through Monday, but area waterways continue to run dangerously cold and swift. * Gusty winds will pose aviation, recreation, and fire impacts Monday with cooler, showery weather Tuesday and Wednesday. && .DISCUSSION... Showers and thunderstorms are expected to increase in coverage through the afternoon from Lassen County into the E Sierra as surface heating increases beneath weak instability aloft (~200 J/kg of MUCAPE sampled in the 12Z REV sounding). Weak N-NW steering flow will direct showers and storms into far W Nevada, increasing the potential for storm impacts as the afternoon progresses. Additional shower/storm development is expected along the zephyr breeze in the late afternoon. The more robust showers and storms will be capable of strong outflow winds up to 50 mph, small hail, brief heavy rain and sudden temperature drops, and occasional lightning. If you`re getting an early start on outdoor recreation for the holiday weekend, make sure you have ways to receive weather alerts today! Weak low pressure near the West Coast will introduce dry, southwesterly flow across the region this weekend, shifting moisture eastward into west-central Nevada. As such, best chances for showers and thunderstorms Saturday afternoon will reside east of US-95 and in southern Mono County. Shower and thunderstorms will also be possible (10-30%) near the Oregon border Saturday, but will be dependent on how far north moisture is displaced. Sunday may feature an uptick in thunderstorm activity as weak low pressure pivots into southern California. The other notable item to keep in mind is that temperatures this holiday weekend will be warm (daytime highs in the mid to upper 70s/80s), but lakes, rivers, and creeks are still running dangerously cold and swift so avoid cooling off in them. A compact Pacific low and attendant cold front will move through the region early next week, increasing the likelihood of strong/gusty winds, showers and storms, and a sharp cooldown between Monday and Wednesday. Wind impacts seem to be of highest concern with this storm, making flights bumpy and lakes choppy. Critical fire weather conditions are also possible Monday afternoon in parts of NE California and NW Nevada (more details below). Sharply cooler temperatures and increased shower chances arrive Tuesday and Wednesday as the cold front sweeps through the region. -Salas && .AVIATION... The main concern today will be scattered showers and thunderstorms this afternoon with greatest chances (20-40%) in the eastern Sierra. While showers/t-storms may begin as early as 18-19Z, the 20-00Z timeframe is favored for greatest thunderstorm coverage and impacts to terminals -- especially at KTRK-KTVL-KMMH. With time, showers and storms may drift into KRNO-KCXP-KMEV. Stronger showers and storms will be capable of brief heavy rain/flight reductions to MVFR, small hail, sudden/strong wind shifts, and lightning. Elsewhere, VFR conditions will prevail with typical west breezes in the afternoon. Shower and thunderstorm potential decreases Saturday as moisture is displaced eastward into west-central Nevada. -Salas && .FIRE WEATHER... A critical fire weather environment remains on track to unfold Monday afternoon across eastern Lassen Co, the Surprise Valley, and much of NW Nevada where gusty winds overlap low humidities. Duration of critical wind/RH is trending towards 4-8 hours in Lassen and far N Washoe County with 2-5 hours in Pershing County. Fuels are the limiting factor in this case as there is uncertainty in the continuity of receptive fuel beds, but local intel from dispatch centers/GACC suggests the cured grasses and sagebrush will be capable of carrying fire in valleys/midslopes of far NW Nevada. Farther south, elevated fire weather conditions will be possible, but fuel conditions aren`t as dry per local units. Cooler temperatures, higher humidity, and increasing shower chances follow a cold frontal passage Tuesday and Wednesday. However, winds will shift from SW to NW behind the front Tuesday. -Salas && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$

091 FXUS66 KSTO 221825 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 1125 AM PDT Fri May 22 2026 .KEY MESSAGES... - Above-normal temperatures today with isolated mountain showers and thunderstorms. - Cooling trend through the weekend and into early next week. - Increased onshore flow through the holiday weekend, combined with low daytime RHs, will lead to elevated fire weather conditions in the Valley. - Winds switch, becoming gusty and out of the north around Tuesday, with continued elevated fire weather conditions. && .DISCUSSION... ...Today to Saturday... GOES-West visible satellite imagery reveals a cloudless Central Valley with some cumulus beginning to bubble-up over the northern Sierra. Synoptically we currently find ourselves nudged between a sagging trough over the Rocky Mountains and a broad, flat ridge over the northern Pacific. The net result for northern California will be another warm afternoon with temperatures around 10 deg F above late-May climatology, as well as isolated mountain showers and thunderstorms for the afternoon. The latest National Blend of Models (NBM) guidance advertises around a 15-25% chance of thunder for the Sierra as well as a 10-15% chance along the Coastal Range. A healthy Delta breeze is forecast to develop this afternoon with the onshore gradients, and will make for a pleasant Friday evening for Solano, Yolo, Sacramento, San Joaquin and Stanislaus Counties. For Saturday, temperatures start to become noticeably cooler for southern Sacramento Valley, northern San Joaquin Valley, and Delta communities as the continued onshore flow influences the max temps. While cooling is expected elsewhere, such as the northern Sacramento Valley, the day-to-day difference is not forecast to be as notable. The onshore flow will continue, and combined with minimum RHs around 18-25%, will result in brief periods of elevated fire weather concerns, particularly in Valley locations away from the Delta where the marine-influenced RHs aren`t realized. Please do be mindful of any holiday weekend activities that involve fire/flame; the fuels will only continue to dry as we dive into the dry season. // Rowe ...Sunday to Thursday... Similar conditions are forecast for the region on Sunday with breezy onshore west/southwest winds as weak troughing develops along the California coast. This will maintain the elevated fire weather concerns through Sunday and into the holiday on Monday. From Monday to Tuesday, an upper-level low will dive south from the Gulf of Alaska toward the Pacific Northwest, then push inland over Oregon by late Tuesday. While the exact details on the low`s trajectory are still to be determined, this pattern setup would result in offshore northerly winds for NorCal, as well as fire weather concerns. Depending on how much moisture accompanies the low, can`t rule out the chance of some mountain convection, as well. // Rowe && .AVIATION... VFR conditions are expected over the next 24 hours. West- southwesterly winds increase after 20Z Friday in the Delta/Sacramento Valley, with north-northwesterly winds in the northern San Joaquin. Valley gusts 15 to 20 kts until 12Z Saturday. Stronger gusts in the Delta up to 25 kts through 18Z Saturday. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$

838 FXUS65 KMSO 221809 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 1209 PM MDT Fri May 22 2026 .DISCUSSION... KEY MESSAGES: - Warming and drying trend expected through the weekend. - Showers and thunderstorms on Memorial Day (Monday). Any lightning, sudden wind, or rapid temperature drop could be impactful to outdoor recreationalists. Cold front moves through by Tuesday morning. - Tuesday could be quite the wet day as a large upper low becomes situated to our southwest. There`s a 50 to 70% probability for widespread rainfall amounts exceeding 0.25" by Wednesday morning. - Upper low keeps unsettled weather going next week, so keep that rain gear handy! This Afternoon: Scattered showers are expected into this evening across northwest Montana and along the Continental Divide. Impacts will be limited to brief, localized rainfall and gusty winds up to 30 mph. However, marginal instability may be sufficient to trigger an isolated thunderstorm, primarily within Glacier National Park. This Weekend/Water Safety: A significant warming trend will bring summer-like temperatures to the region for the holiday weekend. These warm conditions will likely increase outdoor recreation on and around area lakes and rivers. However, local waterways continue to run dangerously cold due to ongoing mountain snowmelt. Plunging into cold water without acclimatization can induce cold-water shock drastically altering breathing, heart rate, and blood pressure, creating life- threatening conditions. Always wear a life jacket and exercise extreme caution. For more information on cold-water hazards, visit weather.gov/safety/coldwater. Monday (Memorial Day): Ensemble guidance has converged significantly regarding Monday`s weather pattern. A large upper-level low is forecast to drop south and east into the Pacific Northwest by Monday. This setup places the region under south-to-southwest flow aloft, a pattern historically favorable for shower and thunderstorm development. While instability appears marginal, it will be sufficient to support lightning, small hail, and gusty outflow winds. As the flow shifts more southerly later Monday, increasing cloud cover will likely limit greater diurnal instability. Boaters and paddlers on area lakes should remain alert for sudden wind shifts and choppy waters. Monday Night through Tuesday Night: By Monday night, wrap-around moisture will overspread the region as a cold front moves into western Montana. Ensemble clusters strongly agree on broad, large-scale ascent through Tuesday night as the upper-level low meanders across Oregon, Idaho, and Nevada. Consequently, the National Blend of Models (NBM) highlights this timeframe for the highest probabilities of widespread rainfall, showing a 50 to 70 percent chance of exceeding 0.25 inches during the 48-hour period ending Wednesday morning. With extensive cloud cover and precipitation, Tuesday will likely be the coolest day of the week, with highs in the 50s and 60s (5 to 10 degrees below seasonal averages). Wednesday through Friday: As the cutoff low stalls to our south and west, a plume of Gulf moisture is projected to advect northward across the Plains and into western Montana by Wednesday and Thursday. Ensembles highlight Precipitable Water (PWAT) values of +2 to +3 standard deviations, or over 150 percent of normal. This unusually moist airmass will heighten the risk for heavy rain-producing showers and thunderstorms. By Thursday, ensemble clusters depict a slow eastward progression, positioning the center of the low over northern Nevada. The ensemble means show the system accelerating slightly by Friday; however, model discrepancies remain, with the ECMWF ejecting the low toward the Yellowstone region while the GFS ensemble maintains a more southerly track. While a below-normal mountain snowpack means mainstem rivers have ample capacity to handle this rainfall, smaller creeks and streams could be highly sensitive to localized heavy downpours. This hydrologic threat will be closely monitored in upcoming forecast cycles. && .AVIATION...Scattered showers are expected this afternoon into early evening across northwest Montana and along the Continental Divide. Sufficient instability may support an isolated thunderstorm near Glacier National Park. Localized wind gusts of 20-25 knots will be possible near any stronger shower or thunderstorm activity, with potential impacts at KGPI. Otherwise, light and diurnally driven winds will prevail at all terminal sites. VFR conditions are forecast to persist through Saturday as a warming and drying trend establishes across the region. Westerly winds do increase on Saturday afternoon with gusts of 15-25 kts. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None. ID...None. && $$

160 FXUS65 KBOI 222002 AFDBOI Area Forecast Discussion National Weather Service Boise ID 202 PM MDT Fri May 22 2026 .KEY MESSAGES... - Mostly dry with temperatures 10 to 15 degrees above normal for Memorial Day weekend. - Gusty winds Monday ahead of a cold front, resulting in elevated fire weather conditions. - Much cooler with gusty winds and a chance of showers and thunderstorms Tuesday and Wednesday. && .SHORT TERM /Through Sunday Night/... A very stable and quiet weather pattern dominates the short term period as high pressure aloft maintains control over the Intermountain West. Clear skies and light winds will allow for efficient radiational cooling overnight, though morning lows will remain above normal. A steady warming trend will continue across southeast Oregon and southwest Idaho Saturday into Sunday as weak northwesterly flow aloft slowly transitions to a more southwesterly regime. This will increase mid level moisture along the Nevada border Saturday afternoon, aiding in CU development and potentially supporting a few isolated showers and thunderstorms (20% chance). By Sunday, temperatures will push to around 5 to 10 degrees above seasonal normals. A strengthening surface pressure gradient ahead of an approaching Pacific low will lead to increasing westerly winds across the region Sunday afternoon, particularly through the Snake River Plain. Expect gusts to reach 20 to 30 mph by late afternoon. While a slight chance of showers and thunderstorms will exist along the Nevada/Idaho border Sunday afternoon, most of the region will remain dry through Sunday night under mostly clear skies. && .LONG TERM /Monday through Friday/... The extended period begins on Memorial Day with southwest flow aloft strengthening across the region. This will push daytime high temperatures to their warmest levels of the week, topping out around 10 to 15 degrees above normal for late May. While lower elevations and valley locations will remain dry, the increased moisture and afternoon instability will support isolated showers and thunderstorms over the higher terrain of southeast Oregon and the West Central Idaho mountains Monday afternoon. Breezy to gusty conditions will develop area wide as a strong upper level trough inches closer to the coast. A major weather pattern shift takes hold on Tuesday and Wednesday as a deep upper level trough moves inland. A strong cold front will sweep through the area, bringing a sharp drop in temperatures, widespread gusty winds, and a significantly higher chance (25% to 60%) of precipitation. High temperatures on Tuesday and Wednesday will plummet to well below normal. Widespread valley showers and high elevation mountain snow showers are expected, providing much needed moisture to the region. The trough begins to exit the region by Thursday, allowing high pressure to slowly rebuild from the south and west. This will start a gradual drying and warming trend that carries into Friday, bringing temperatures back toward seasonal averages by the end of the work week. && .AVIATION /18Z Friday through Saturday/...

(Today through next Friday) WEATHER PATTERN OVERVIEW: A light northwest flow aloft continues across the region today with winds of 5 to 10 mph gusting 10 to 20 mph this afternoon. Main change for today will be across central NV, generally south of the Highway 50 corridor where mid-level moisture and instability will increase enough for weak cell development. There is a 5 to 15% chance of thunderstorms between noon and 5PM PDT over and near mountains of northern Nye, southern Lander and Southern Eureka counties. Any precipitation would be less than five hundredths of an inch in mountains and probably virga over any valley locations. Increasing clouds across the CWA Saturday afternoon with a 5 to 10% chance of thunderstorms. NBM has isolated showers and thunderstorms Saturday afternoon limited to NW Humboldt and along the southern Lander, southern Eureka and far northern Nye counties. Expecting increased areal coverage of low end thunderstorm chances Saturday afternoon in upcoming model runs as some model ensembles have shown 5-15% chances of thunderstorms for multiple runs. Similar to this afternoon, any storms that may develop on Saturday would be expected to produce less than five hundredths of an inch of rain. Sunday afternoon weak instability is focused across Elko county, with a 10 to 20% chance of afternoon convection mainly over the mountains of northern Elko county and the Ruby mountains. Warmer this weekend with highs ranging from upper 70s to mid 80s. A storm system will impact Northern and Central Nevada Tuesday afternoon through Wednesday night, resulting in a chance of valley rain and mountain snow. Snow levels will start at around 8,000 feet Tuesday afternoon, before dropping to about 7,000 feet Tuesday night. The majority of this precipitation will fall Wednesday. Strong, gusty southwest to west winds are anticipated, mainly in Central Nevada, from 10 AM PDT Tuesday morning until 11 PM PDT Tuesday evening. A Wind Advisory may be required. FORECAST CONFIDENCE & DEVIATIONS: Low confidence in thunderstorm activity across portions of central NV this afternoon. High confidence in temperatures tending warmer through the weekend. High confidence continues with respect to gusty winds Monday and Tuesday. Low forecast confidence in valley rain and mountain snow Tuesday afternoon through Wednesday night. Slight adjustments to the NBM POPs for this afternoon to get thunderstorms mentioned in the forecast across central NV, which now matches up with the Storm Prediction Center Convective Outlook. Also nudged cloud cover up slightly across central NV this afternoon. && .AVIATION...VFR conditions are expected at all TAF terminals today and tonight. Mid-level clouds will increase across portions of central NV this afternoon with a 5-15% chance of thunderstorms. Not expecting any thunderstorms to develop at or in the vicinity of KTPH or KELY however. && .FIRE WEATHER...Thunderstorm chances for portions of Central Nevada both this afternoon and Saturday afternoon will be in the 5 to 15% range. Sunday afternoon the best chances for thunderstorms will be across Elko county, where chances are currently in the 10 to 20% range. Any thunderstorms that may develop today through Sunday are expected to be dry. Strong, gusty southwest to west winds anticipated Tuesday associated with the passage of a cold front. Valley rain and high elevation snowfall is expected Tuesday into Wednesday. && .LKN Watches/Warnings/Advisories...None. && $$ DISCUSSION...96 AVIATION...96 FIRE WEATHER...96
