380 FXUS66 KSEW 241600 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 900 AM PDT Sun May 24 2026 .SYNOPSIS... Another cool and cloudy start to the day is expected, breaking out in the afternoon for more sunshine. A low pressure system brings rain, breezy winds and chances for thunderstorms to the region on Monday. Showery weather continues on Tuesday, with a return to high pressure likely later in the week. && .SHORT TERM /TODAY THROUGH TUESDAY/... With much less stratus across the area this morning, clouds are already starting to erode around the edges and places should get more sun earlier than yesterday. Highs will also be a touch warmer than yesterday. Highs are likely to be in the mid to upper 60s, possibly 70 in locations that clear the stratus first. Today will be the last dry day of the long weekend, as a low pressure system brings rain, breezy winds and slight chances for thunderstorms to the region on Monday (Memorial Day). Rain is likely to arrive on the coast late tonight, spreading inland throughout the day on Monday. QPF looks to be around a tenth to quarter inch for the lowlands, and up to an inch on the windward slopes of the Olympics. Breezy south to southwesterly winds will pick up late Monday morning, and will be strongest along the immediate Pacific coast, Admiralty Inlet, eastern Strait of Juan de Fuca and in the northern inland waters from Skagit county north. These areas may see gusts of 35 to 40 mph. Unsecured outdoor items like tents may be at risk during these winds. Additionally, while SPC has western Washington highlighted for general thunderstorm risk on Monday, outdoor events could still be impacted by typical thunderstorm hazards such as heavy rain and lightning. Chances are slight, around 10 to 20%, but remember to head indoors when thunder roars. Temperatures on Monday will be a lot cooler, down into the upper 50s and low 60s. Showery and unsettled weather continues into Tuesday as the trailing front moves through the region. Isolated thunderstorm chances remain in the forecast. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... The low pressure system responsible for Monday and Tuesday`s weather will continue to dig south, leaving the PNW in split flow to gentle ridging into the mid and late week. As such, temperatures begin to warm from Wednesday onward, reaching highs back into the mid 70s by Thursday. Ensembles and deterministic guidance are hinting at broader troughing over the NE Pacific late in the week for potential for more unsettled weather. With the broader NE Pacific troughing, long period swell arriving Thursday poses a bigger threat for extended wave runup on coastal beaches. 21/62 && .AVIATION... West-southwest flow aloft today will become more southwesterly by this evening as an upper level trough approaches the Pacific Northwest from the northeastern Pacific. Weak onshore flow continues in the low levels. Latest satellite imagery depicts another round of stratus across Puget Sound this morning, however cloud cover is not as thick or extensive as yesterday and satellite trends have already indicated stratus scattering in some spots. Expect this trend to continue over the next few hours, with an overall breakout of the stratus deck expected by 18-19Z. Conditions at the area terminals largely remain low-end VFR as a result, though a few terminals across the central and south Sound in stratus have dropped to MVFR. High clouds will also continue to stream overhead and increase through the day ahead of the next system on Monday. VFR cigs are expected this afternoon with continued SCT/BKN high clouds. Surface winds will primarily remain S/SW between 5-10 kt through the day. KSEA...MVFR conditions this morning in stratus. Stratus will continue to lift and scatter between 16-18Z for a return to VFR by late morning. VFR conditions will persist through tonight with high clouds expected to stream overhead at times. SW winds will persist through this afternoon mainly ranging between 4-8 kt. The cloud deck will gradually lower Monday morning as the next frontal system approaches. 14 && .MARINE... High pressure will weaken through today with lighter winds into this evening across area waters. A low pressure system will move through the waters on Monday bringing increasing south to southwest winds. Winds will peak late tonight into Monday morning for the Coastal Waters and during the day Monday for interior waters. A Gale Watch has been issued for the Coastal Waters, as well as the eastern Strait of Juan de Fuca and northern inland waters. Probabilities for wind gusts exceeding 35 kts range 50 to 80 percent for these areas, thus giving enough confidence for a Gale Watch at this time. Small Craft Advisory winds are also expected for most other waters on Monday. Winds will slowly ease late Monday into Monday night. High pressure will then build back Tuesday into Wednesday bringing the return of Small Craft Advisory northerly wind gusts and steep seas to the outer coastal waters. Seas will range 6 to 8 feet through this evening before building to 12 to 16 feet by late Monday. Waves will peak around 13 to 16 feet into Tuesday morning before slowly subsiding to near 10 feet by Wednesday. A long period swell arrives Wednesday night into Thursday. This, combined with continued northwest surface winds, results in seas building again to 10 to 13 feet. JD && .HYDROLOGY...

624 FXUS66 KPQR 241757 AAA AFDPQR Area Forecast Discussion...UPDATED National Weather Service Portland OR 1057 AM PDT Sun May 24 2026 ...Updated aviation discussion... .SYNOPSIS...High pressure will deliver one more warm, dry day today, while the coast stays cooler at times under patches of marine clouds and drizzle. Confidence remains high in a sharp shift late tonight into Monday as a Gulf of Alaska system spreads widespread rain, breezy winds, and much cooler temperatures across the area. Showers linger into Tuesday with a low-end thunder chance, then conditions trend warmer and drier late next week. && .DISCUSSION...Now through Saturday...Early this Sunday morning, the region remains on the warm side of the pattern beneath upper-level high pressure. Even so, onshore flow near the surface is still enough to bring marine clouds back to the coast and into some adjacent valleys at times. Any coastal drizzle/mist would be confined mainly to the morning hours. For today, temperatures will again run warm inland, but the final outcome will hinge on how much marine cloud cover hangs on near midday. Current expectations still favor the warmest highs of the weekend across interior valleys, generally upper 70s to lower 80s, while the coast stays cooler in the low 60s to low 70s. Cascades and foothills should stay in the mid 60s to mid 70s. If clouds push farther inland or linger longer than anticipated this morning, some locations could end up 5-10 degrees cooler than forecast. The forecast turns much more active late tonight into Memorial Day. A broad low dropping out of the Gulf of Alaska will drive a frontal system into the Pacific Northwest, bringing widespread rain and thick cloud cover. Rain should begin along the coast around early Monday morning, then spread inland during late Monday morning/early Monday afternoon. Recent guidance now supports 24 hour rainfall totals (roughly 5 AM Monday to 5 AM Tuesday) in the 0.20 to 0.90 inch range, with the greatest totals and highest probabilities along the coast, Coast Range, Cascades, and Cascade foothills. Probabilities for at least 0.25 inch are generally 50-90%, while chances for 0.50 inch or more are lower in the Willamette Valley (5-35%) but remain much higher for the coast, Coast Range, and Cascades (around 60-90%). A corridor from Florence OR north toward Seaside OR continues to show the best odds for 1.00 inch or more (roughly 20-40%). Winds will also pick up early Monday as the front moves through. Currently probabilities strongly favor gusts exceeding 25 mph across much of the area (around 80-99%). Gusts over 30 mph are more likely along the coast (about 70-90%) than inland (40-60%). Higher-end gusts around 35 mph or greater remain a lower-probability outcome inland (roughly 5-20%) but are more plausible along the coast (35-55%). Even without advisory-level winds expected inland, these speeds can still impact tents, canopies, and other unsecured items. By Tuesday, the low shifts southeast with showers lingering and a more southerly flow developing. That setup is more supportive of isolated thunderstorms, and a 15% chance appears reasonable for the Willamette Valley and Cascades by late Tuesday morning into Tuesday afternoon. From midweek into late week, guidance trends toward a warming and drying pattern as weaker high pressure/zonal flow returns, though temperatures will likely remain cooler than this weekend`s warm spell. While confidence remains low, ensemble guidance suggests that the weak high pressure ridge will weaken Friday as a broad trough over the Northeast Pacific nears the Pacific Northwest. ~12 && .AVIATION...Satellite imagery as of late Sunday morning depicts mostly sunny skies with a few high clouds as dry westerly flow prevails aloft. Will maintain predominately VFR conditions through this evening with increasing SCT/BKN high clouds ahead of the next system. This system will swing a cold front through the coast after 12-15z Sun, returning light rain and high confidence (60-70% chance at any given hour) for MVFR CIGs after 12z Mon. Still some uncertainty with exactly when MVFR conditions return along the coast, as some guidance has it arriving as early as 06-09z Mon, or as late as 12z Mon. For inland terminals, CIGs gradually fall to low- end VFR by the end of the TAF period as the front doesn`t push through the Willamette Valley until after 18z Mon. Northerly to northwesterly winds under 10 kt through 21z Sun, turning more westerly this afternoon and south-southwesterly tonight. Breezier southerly winds with gusts up to 20-25 kt return after 12z Mon along the coast and central/southern Willamette Valley return as the front approaches. KPDX AND APPROACHES...VFR conditions through the TAF period with increasing SCT/BKN high clouds today ahead of the next system. Northwesterly winds under 10 kt today turn westerly after 21z Sun and southerly after 08-10z Mon. -10 && .MARINE...Breezy winds have weakened early this morning and will continue to weaken through today. Seas will remain around 6 to 8 feet through tonight. A frontal system will impact the waters Monday into Tuesday. Winds turn westerly and increase early Monday morning as the front approaches and moves through the waters. Latest guidance indicates widespread wind gusts up to 25-30 kts, strongest north of Cape Foulweather, with a 35-50% chance of gale force wind gusts, mainly isolated and right along the frontal passage from 2 AM to 8 AM Monday. Waves are forecast to rise behind the frontal passage Monday afternoon into Tuesday morning. There`s high confidence (90+% chance) of significant wave heights exceeding 13 feet. Additionally, there`s around a 25% chance significant wave heights could reach 17-19 feet for locations 20 nm and beyond west of the coast, and a 10% chance of 20 feet seas for locations 30 nm and beyond west of the coast. As a result, a Small Craft Advisory has been issued from 11 PM Sunday to 5 AM Monday for wind gusts around 25 to 30 kt. Additionally, a Hazardous Seas Watch has been issued from 5 AM Monday to 11 AM Tuesday for very steep and hazardous seas, while also highlighting possible isolated gusts up to 35 kt from 2 AM to 8 AM Monday for the waters north of Cape Foulweather OR. Waves forecast to decrease through Tuesday afternoon to around 10-12 feet. ~12/03 && .PQR WATCHES/WARNINGS/ADVISORIES... OR...None. WA...None.

990 FXUS66 KMFR 241101 AFDMFR Area Forecast Discussion National Weather Service Medford OR 401 AM PDT Sun May 24 2026 .DISCUSSION... Not much will change from Saturday as the upper air pattern remains zonal with some weak embedded short waves. Just like yesterday, we had to increase PoPs and the chance of thunder to get some mention of thunderstorms in the forecast around northern California. Any storms or showers that do from will be isolated and fairly weak with limited lightning activity. In any case, it will be another warm day as highs push into the 80`s and perhaps 90 here in Medford. We`ve hit that 90 degree mark the last few days at the office. The weather pattern really begins to change on Monday as a deeper trough in the Pacific approaches the coast on Monday morning. In addition, a well defined cold front should push onshore by the afternoon hours, which is a bit slower than what the models were showing the last few days. The latest set of guidance shows this front bringing wetting rain to the coast, although it will be notably drier farther inland, even for some locations west of the Cascades near the California border. Winds remain the other topic of concern as this front moves into Oregon. Forecast soundings continue to show deep mixing during the afternoon hours with dry adiabatic lapse rates up to 600 mb east of the Cascades. It looks very likely we`ll mix down wind gusts around 40 mph with some areas gusting to 45 mph. The extreme forecast index(EFI) also made a concerning tick upwards with the 0Z ensemble run Saturday evening. It`s now highlighting EFI wind gust values of 0.99 to 0.90 across our forecast area. Values this high denotes the ensemble wind gust forecast exceeding model climatology for the time of year, which is unusual. Another concern is the shift of tails around 1-2, which suggests about 10% of the ensemble members are predicting wind gusts in the extreme of model climatology for late May. So what does this all mean for impacts? Wind gusts this strong could produce isolated power outages. Also, any events outdoors should plan for some stronger wind gusts in the afternoon and evening. There are also some fire weather concerns as wind gusts mixed with low relative humidity farther to the east will increase the fire weather risk, especially in Lake County. Eventually, this front and trough will push through Oregon Monday night into Tuesday and temperatures will trend significantly cooler with highs in the lower 60`s in the Rogue Valley. Thats about a 30 degree trend lower compared to forecasted highs today. This low will become cutoff and bring us a continued chance of showers and perhaps some embedded thunderstorms through most of next week. Given the cooler and wetter airmass, we`re not concerned about major weather impacts from these showers or thunderstorms. If anything, the rain from these thunderstorms will be beneficial given how dry it has been this Spring and Winter. && .AVIATION...24/12Z TAFS... Late tonight and early Sunday morning, expect areas of IFR/LIFR to redevelop along the coast, mainly from Cape Blanco northward and from Gold Beach southward. Conditions are expected to clear to VFR around 18z. Elsewhere, expect continued VFR. Cumulus build ups and isolated showers and thunderstorms are expected in Siskiyou County east-northeastward into far southern portions of Klamath and far southeastern Lake counties. && .MARINE...Updated 345 AM PDT Sunday, May 24, 2026...Gusty north winds will keep seas steep through Sunday morning. Wave heights will be relatively low around 6 to 8 feet at 7 seconds. A cold front will move through the waters on Memorial Day bringing rain and increasing seas. Seas are likely to become steep again on Monday afternoon, with the highest probability, strongest south winds expected to occur north of Cape Blanco. Swell dominated seas are expected to reach a peak on Tuesday at around 13 to 16 ft at 14 seconds. High pressure offshore and lingering low pressure inland are likely to bring increasing north winds on Wednesday with gales possible south of Port Orford. Gusty north winds are likely to continue steep to very steep seas Wednesday night into Thursday while a long period west-northwest swell builds. && .MFR WATCHES/WARNINGS/ADVISORIES... OR...CA...None.

895 FXUS66 KEKA 240754 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 1254 AM PDT Sun May 24 2026 .SYNOPSIS...Stratus continues to dominates over the coastal areas. Above average temperatures persist inland with slight afternoon thunderstorm chances. A cold front arrives Monday evening bringing chillier temps. and light to locally moderate rain Tuesday for the North Coast as well as widespread breezy winds through the week. && .DISCUSSION... .SHORT TERM...Stratus is persistent as coastal eddies recirculate the marine layer towards the lower elevations along the coastline. surface flow back into the lower elevation coastal areas. Stratus has socked in the Pacific coastline from the OR boarder down to San Fransisco Bay. There are slightly higher chances (40-30%) of coastal clouds clearing today compared to the previous days. Overcast conditions return overnight before a low pressure system arrives Monday evening. Through Monday, inland areas can expect continued above normal temperatures with an ever so slight convective potential (10-15%), especially for the Trinity Horn. Warm surface temperatures and above normal PWAT values will most likely allow for isolate thermal updrafts off mountainous terrain to tap into elevated CAPE leading to possible thunderstorms. Models show these storms beginning around 11am at the earliest and remaining through 7pm for Trinity County in the Trinity Horn and near the Yolla Bolly Mtns. .LONG TERM...Monday evening, a cold front will dip into the area increasing the likelihood for rain in Del Norte and Humboldt counties, forcing strong NW winds in its wake, and drastically decreasing inland temperatures on Tuesday (~70F). Rain totals look mostly benign with the more extreme models (75th percentile) showing between 0.25-0.5" in Del Norte Co. and <0.25" for Humboldt Co. for the duration of the storm. Little to no moisture is forecasted outside of the far North Coast area. Winds will increase in the wake of the front for Tuesday and Wednesday afternoon with gusts up to 30-40mph possible. Details on the strength of the wind will depend on the path of the front. Global models are beginning to show more confidence on this path with each new forecast run. As the models close in on a path, a tighter range of timing, location, and strength will be available soon. DS && .AVIATION...LIFR conditions along the coast will continue through the night with minimal clearing during the daylight hours Sunday. There is moderate confidence of conditions better the MVFR (~60%) and IFR (~50%) between 18Z-04Z for the North Coast. Southerly winds will prevail with periodic afternoon gusts at KCEC. Stratus has the potential (~70% of ceilings <3000ft AGL)to reach KUKI again tonight as southerly winds and a deep marine layer remain. VFR conditions will redevelop by 18Z Sunday. A chance (10-15%)of thunderstorms are possible in over NE Trinity County. DS && .MARINE...Strong northerly winds continue to ease and are mostly constrained to the outer waters, especially in the far northern waters in the lee of Cape Blanco. Seas are forecasted to ease through the day Saturday as winds subside. The small craft advisory has been extended through 3am Saturday morning as steep waves continue at the Cape Mendocino buoy. This leaves the steep seas mostly constrained to the outer waters. Winds and seas continue to ease Sunday and Monday, with generally light southerly winds expected. Global models are increasing the forecast confidence for the storm path of a weak cold front entering the area Monday evening. Winds and seas rapidly increase as strong NW winds fill in after the front. Expect these to build substantially through the week, especially for the southern outer waters where there is an 80-100% probability of gale force winds developing by Tuesday. A NW swell this weekend will mix with fresh NW short period seas making a relatively chaotic sea state as combined sea heights build up to 16ft through the coming week.

Issued at 1257 AM PDT Sun May 24 2026 (Today through Monday) Surface troughing will continue through Memorial Day Weekend. This will keep the marine layer deep around 2,000 feet with early returns and late clearings. Sensible weather wise, temperatures will remain near to slightly below normal with onshore flow. Gusts of 25-35 mph are expected along the coast, across ridgelines, and through west- east oriented gaps and passes. && .LONG TERM... Issued at 1257 AM PDT Sun May 24 2026 (Tuesday through Saturday) Global ensemble clusters are in agreement of upper-level troughing arriving Tuesday, marking the coolest day of the week. Strong northerly winds will develop, bringing gusts of 30-40 mph to the coast, across ridgelines, and through gaps and passes with widespread hazardous conditions for small craft across the waters. As the trough digs, it is expected to become a cutoff low. While there is uncertainty in the exact location, strength, and timing, it is looking likely that an inside slider like pattern will develop Wednesday into Thursday. While inside slider is usually synonymous with elevated fire weather conditions, good to excellent overnight relative humidity recovery will help mitigate these concerns for now. This pattern will support northerly (drying) winds, kicking off a gradual warming and drying trend. The aforementioned cut off low will fill and become an open wave by Friday, leaving zonal flow with onshore flow in its wake. && .AVIATION... (12Z TAFS) Issued at 500 AM PDT Sun May 24 2026 The marine layer is well established, leaving the majority of the sites with MVFR cigs this morning. Expect these conditions to continue through the morning, with perhaps a few pockets of IFR cigs being possible. Stratus burns off by mid to late morning, with VFR conditions returning to most interior locations. Stratus should along the coast to some extent which could leave sites like KHAF with MVFR cigs all day. Given no real pattern change today, look for the marine layer to return and bring another night of MVFR cigs. Vicinity of SFO...Stratus has yet to fill in at KFSO, but satellite shows it slowly advancing to the terminal. Expect MVFR cigs to fill in, which will then last through mid to late morning. VFR conditions will then prevail through at least the evening hours. Given the pattern looks to stay the same, MVFR cigs should return to SFO early Monday morning. Pushed the timing back some given what has occurred the last two days, with skies clearing by 17Z. Medium to high confidence in the forecast. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...MVFR cigs plague the terminals around Monterey Bay, as the marine layer holds at about 2000ft this morning.

791 FXUS66 KOTX 241742 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1042 AM PDT Sun May 24 2026 .KEY MESSAGES... - A cold front on Monday will bring isolated thunderstorms to eastern Washington and north Idaho for the late afternoon and evening hours. A few storms may become strong near to and south and east of Pullman/Moscow area. - There is a growing threat for thunderstorms Thursday and Friday with a 20-30 percent chance of being widely scattered across the region. Some thunderstorms may be strong with a risk for hail, gusty outflow winds, and heavy downpours. && .SYNOPSIS... Dry conditions with above normal temperatures will continue through the weekend. A cold front on Monday will bring breezy to windy conditions late in the day. The cold front will also bring showers with a chance for thunderstorms especially in the Idaho Panhandle. Cooler temperatures Tuesday into Wednesday. Widely scattered showers with the potential for Thunderstorms Thursday into Friday. && .DISCUSSION... Today through Monday Night: Satellite shows a large closed low dropping southeast towards the region from the Gulf of Alaska. Dry southwest flow ahead of this low will be over the Inland NW today. Temperatures will be a few degrees cooler compared to Saturday, but still about 7-10 degrees above normal with highs in the mid 70s to low 80s. Then changes arrive Monday as the upper low drops south to just off the southern WA coast Monday evening. This low track will bring an increase in large scale lift, with a passing cold front bringing an added kicker to initiate increasing bands of rain showers. Ahead of the cold front isolated thunderstorms are also forecast to develop due to elevated instability along and east of line from Ritzville to Colville with 850-500mb MU CAPE of 100-300 J/KG. Greater surface based instability will be present from the Blue Mountains into the Central Panhandle Mountains with modeled surface based CAPE as high as 1000-1500 J/KG with strong 0-6km shear of 50 kts. These gradients raises the risk for strong thunderstorms (mainly for the Camas Prairie), although the opportunity is brief as cooler, and more stable surface based air floods in with the cold front. This is something that will continue to be monitored. The other issue with this front will be the winds, with a burst of west winds with the cold front with high resolution modeling show 30-40 MPH gusts from the Wenatchee area into the Columbia Basin. These strong wind bursts can often pick up patchy blowing dust, but confidence is currently low given wetting rains that occurred a week ago, and also past peak spring planting season. Tuesday and Wednesday: The low continues its southeast track, moving into southern Oregon on Tuesday and then central California and Nevada Wednesday. The low is still in close proximity for additional bands of showers, with the highest chances shifting to SE Washington and the ID Panhandle. Tuesday will be much cooler due to the cooler air behind the Monday front passage, and then warmup into Wednesday with the low shifting south. Thursday through Saturday: The low to our south remains parked there going into Thursday. Temperatures will warm further but this will also increase the instability over the region as increased moisture gets drawn up from the southeast with precipitable water increasing to 150-200 percent of normal. Chances for showers and thunderstorms increase further heading into Friday as an upper trough dropping in from the northwest interacts with the warm, moist, air mass. Surface based CAPE increases to 500-1500 J/KG, with gusty outflow winds, lightning, and heavy rain expected to be the thunderstorm hazards. Drier and more stable weather conditions are expected for Saturday as the moisture and instability push east of the area. JW && .AVIATION... 18Z TAFs: VFR conditions will continue through the period into Monday. Breezy westerly winds into this afternoon with gusts of 15-25kts across the Columbia Basin (KMWH) into the Spokane- Coeur d`Alene area (KGEG/KSFF/KCOE) and Palouse (KPUW). A cold front pushes across the Inland Northwest late Monday afternoon. The front will bring widely scattered showers and thunderstorms to the Idaho Panhandle along with gusty and shifting winds.

143 FXUS66 KPDT 241736 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 1036 AM PDT Sun May 24 2026 .Updated Aviation Discussion. .KEY MESSAGES... - Warm, dry conditions today - A low-pressure system and cold front are slated to arrive Monday afternoon and evening, ushering in widespread breezy to windy westerly winds and a slight chance of thunderstorms - Shower and thunderstorm chances continue Tuesday through the week, but uncertainty remains in forecast details && .DISCUSSION... Above-normal temperatures and dry conditions will continue today as the region remains under zonal flow aloft. Locally breezy winds coupled with widespread low afternoon relative humidity will lead to locally elevated fire weather concerns, but no headlines are in effect. The next feature that will drive our weather Monday through the remainder of the week, a deepening closed low, is visible in water vapor imagery, located offshore in the vicinity of the Gulf of Alaska. Ensemble NWP guidance is unanimous in taking the closed low southeast along the Pacific coast into Monday. Ensemble solutions exhibit some subtle differences with regard to timing and location/track as it begins to move onshore Monday, but confidence in the low and its attendant surface cold front providing a pattern change late Monday is very high (99 percent). Monday, flow aloft will turn southwesterly, and widespread breezy winds coupled with low relative humidity are forecast across central Oregon and the Eastern Mountains prior to the arrival of the cold front mentioned in the previous paragraph. This will lead to some elevated fire weather concerns, but none of our fire weather zones have been declared ready for Red Flag Warnings yet so no headlines are currently planned. Temperatures will be well above normal for the aforementioned region as well as portions of the Columbia Basin and Blue Mountain foothills. By late Monday, the upper low and attendant surface cold front are slated to arrive, with the front sweeping from west to east from afternoon through late evening. NBM probabilities of exceedance suggest medium-high chances (40-85 percent) of reaching or exceeding advisory-level wind gusts across all of our non-mountain zones. Moreover, the NBM is advertising a chance (locally 30-60 percent) of exceeding warning-level gusts (58 mph or greater) across wind-prone portions of the Blue Mountain foothills as well as central Oregon, the Simcoe Highlands, the Yakima Valley, and the eastern Columbia River Gorge. Think the latter probabilities are too high relative to what raw guidance is showing; nonetheless, wind headlines may be needed. In addition to the strong, gusty winds Monday afternoon and evening, there is a low (5-15 percent) chance of high-based showers and thunderstorms across the Columbia Basin, Blue Mountain foothills, and Blue Mountains (mainly the northern Blues). All deterministic guidance is highlighting some elevated instability, and synoptic-scale forcing appears to be supportive of kicking off some showers or thunderstorms given a sufficient mid-level moisture field. The NBM has yet to include a mention of these showers and thunderstorms in the forecast prior to 5PM PDT Monday, but does include showers across the region after 5PM as the front moves through. Tuesday through the remainder of the week, shower and thunderstorm chances will continue, tied to the location of the upper-level low as it tracks inland across the Great Basin (likely Tuesday through Thursday) and eventually ejects north- northeast across the Great Basin, Pacific Northwest, or Rockies by Friday and Saturday. Ensemble cluster analysis suggests a pretty even split (40-60 percent, varying by day) regarding the low being in a location supportive (or along a supportive track) for showers, thunderstorms, and notable spring precipitation for the forecast area. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/...

495 FXUS65 KREV 240754 AFDREV Area Forecast Discussion National Weather Service Reno NV 1254 AM PDT Sun May 24 2026 .KEY MESSAGES... * Warmer than average temperatures persist through Monday, area waterways continue to run dangerously cold and swift with continued snowmelt. * Showers and thunderstorms expected each afternoon through the holiday weekend, posing impacts to outdoor activities. * Gusty winds will bring aviation, recreation, and fire impacts Monday and Tuesday with cooler, showery weather from mid to late week. && .DISCUSSION... Showers today will migrate southward as the shortwave moves over central Nevada, bring the best chances (25-45%) over Mono County early this afternoon. Then, chances taper to around 20-35% and move over eastern Mono and western Mineral counties for early evening. Overall, winds will be light and variable this morning, but will become westerly as gusts of 15-20 mph arrive for the afternoon. One exception will be in the vicinity of any decaying storm, where gusty outflow winds may reach 35 mph. Other hazards with these storms may consider a 20-25% chance for embedded lightning, potential for heavy rain, pellet showers or small hail. Additionally, gusty winds associated with storms may bring choppy lake waters, blowing dust over desert sinks. Monday will be our last day of warm weather, it will also see returning shower chances to Mono County (10-25%) for the afternoon. Elsewhere, to the north, gusty westerly winds will be on the increase Monday afternoon. The higher gusts will be found across northern Washoe and Lassen counties into Surprise Valley in Modoc County. Gusts of up to 45 mph are possible for these areas. Further south, across Pershing County, gusts of up to 40 are more likely, as the bulk of the winds will be found along the Oregon Border. This, along with poor overnight relative humidity recoveries and low daytime RH readings, has prompted the issuance of a Fire Weather Watch. See more detail in the Fire Weather section of the discussion below. Those winds will signal the incoming cold core closed low that will drop in from colder Canadian air and drop our temperatures back into mid April territory. This will be about 5 degrees below seasonal average by Wednesday, when widespread shower chances arrive. This low, as mentioned, will draw down cold air that will bring snow levels toward 7000-7500 feet by Wednesday morning. This will introduce snow chances for our higher peaks, although amounts look on the light side fo accumulations, with only 1-2 inches for peaks around the Tahoe Basin, and 2 to 6 inches along the Sierra Crest in Mono and southern Alpine counties. Given that this closed low is slow to move out, shower chances, chilly temperatures and gusty to breezy wind will be our flavor of the week through Friday. A weekend warmup awaits us on the other side of this chilly week ahead. HRICH && .AVIATION... * VFR conditions are expected for most E.Sierra/W.Nevada terminals today with typical afternoon westerly gusts around 15-20 knots. KMMH could see showers this afternoon, 30-40% chances after 20z, with 15-20% chances of isolated thunderstorms which could yield MVFR conditions from brief heavy rain along with lightning, gusty outflow winds, and small hail. * A strong cold front is expected to produce strong and gusty winds Monday into Tuesday. Wind gusts up to 30-40 mph will be favored mainly northward of I-80 on Monday before shifting south of US-50 Tuesday afternoon as the front moves through. * Expect increasing chances for turbulence, LLWS, and areas of reduced visibility due to areas of blowing dust which could impact KLOL, KNFL, and KHTH. Fuentes && .FIRE WEATHER... * Critical fire weather conditions due to gusty winds and low humidity are expected Monday afternoon and evening as a strong cold front approaches the NE California and NW Nevada. * A FIRE WEATHER WATCH remains in effect for eastern Lassen County, the Surprise Valley, N.Washoe County, and the western Humboldt Basin, including the Quartz Fire (NE Pershing County) in anticipation of gusty winds and low RH Monday afternoon. * Southwest to west winds will increase early Monday afternoon with sustained winds of 20-30 mph with gusts up to 45 mph across NE California and N.Washoe County. Areas across Pershing County (W.Humboldt Basin) may see gusts a touch lower around 30-40 mph. Minimum relative humidity is expected to be around 10-15%. * The duration of critical wind/RH is trending towards 3-7 hours in Lassen and far N. Washoe County with 3-6 hours in Pershing County. * Uncertainty remains on the continuity of receptive fuel beds, but local intel from local fire partners and the recent Quartz Fire ignition 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. * Winds remain elevated on Tuesday and will shift from southwesterly to north/northwesterly as a cold front sweeps through the region. Temperatures cool and humidity rises behind the front, with increasing chances of showers Wednesday and Thursday. Salas/Fuentes && .REV Watches/Warnings/Advisories...

Current satellite has clear skies across the area, with 5-15mph winds. Temperatures are expected to reach into the 80s to low 90s today, with minimum RH values in the upper teens to 20s within the Valley and portions of the Sierra. Winds will be breezy at times this afternoon out of the southwest. This combined with the low RH values bring periods of elevated fire weather conditions for the Valley where the winds are highest. Temperatures remain warm Sunday and into Monday, with the warmest conditions in the northern Sacramento Valley and into portions of the northern San Joaquin Valley. An approaching low pressure system from the eastern Pacific will help bring down temperatures in the southern Sacramento Valley and into the Delta by Monday. Highs on Monday will be in the 70s to lower 80s in portions of the southern Sacramento Valley and through the Delta thanks to onshore flow from the approaching system. Other areas will continue to see upper 80s to lower 90s. Winds remain breezy Sunday out of the SW, but as the low pressure moves closer to the region Monday winds do increase. Winds have the potential to gust 25-35 mph Monday. This combined with low RH values in the Valley bring Elevated Fire Weather conditions. 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. ...Tuesday through Friday... The upper level system moves onshore and through the region Tuesday through Thursday switching the winds from the southwest toward the north to northeast. As this happens we increase our winds, with gusts 35-45 mph possible Tuesday and Wednesday within the Valley. Drier air is filtered into the Valley helping to low daytime RH values into the teens. Localized lower RH values are possible in the northern Sacramento Valley. Right now, we are looking at Elevated Fire Weather conditions Tuesday evening through Wednesday when the winds are the highest and combined with low RH values. Confidence in the temporal resolution of RFW conditions are lower as criteria isn`t reached on a consistent basis. None the less, confidence is increasing on the Elevated Fire Weather concerns in general and we will continue to monitor the need for any products for Tuesday through Wednesday as we push through the weekend. On top of fire weather conditions, we have the chance for isolated showers and storms within the Sierra and parts of Shasta county Tuesday through Thursday. A few higher based storms are possible with 15-25 percent chances (highest in the Sierra south of Highway 50). Confidence remains low on timing, strength, and development of these storms as we have limited moisture and instability as the low pressure moves through. Temperatures will start to warm during this time and reach back into the upper 80s for the Valley by the end of the week as a high pressure builds into the region. && .AVIATION... VFR conditions are expected for the TAF period. South to southwesterly winds increase through the afternoon for the Sacramento sites, with northerly winds in SCK and MOD. Winds have the potential to gust up to 20kts this afternoon and evening for the Sacramento Sites. Around 6z winds start to go light and variable, with clear skies overnight. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$

397 FXUS65 KMSO 240920 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 320 AM MDT Sun May 24 2026 .DISCUSSION... KEY MESSAGES: - Warming and drying trend through the today and tomorrow. - Thunderstorms return to western Montana tomorrow and Tuesday. - An upper low arrives tomorrow into Tuesday causing a cool down and active, wet weather the rest of the week. A warming and drying trend under a broad, weak ridge will last through tomorrow. Temperatures will rise to about 15 degrees above average by tomorrow. Models have trended earlier in their timing for thunderstorms ahead of the cold front for tomorrow night. As a result more locations in western Montana will see thunderstorms tomorrow afternoon. The showers and thunderstorms spread across central Idaho and even into northwest Montana by tomorrow evening. Ensembles agree very well on a closed upper level low moving into the region late tomorrow into Tuesday. This will cause a drop in temperatures to about 5 degrees below average for this time of year on Tuesday. The most uncertainty remains in the precipitation amounts that the region will receive. These values are heavily dependent on how fast the upper level low moves and exactly what track it takes, though trends in the ensembles are favoring more rain for western Montana and particularly southwest Montana. After the sharp cool down on Tuesday, temperatures will trend warmer the rest of next week with active weather as the upper level low stumbles out of the region. Ensemble guidance has also been trending wetter for the rest of the week as more members are favoring a slower transition out of the region. && .AVIATION...A broad and weak ridge continues to dominate the weather across the northern Rockies this weekend.

Issued 216 AM MDT SUN MAY 24 2026 Latest models still show Monday the warmest day before a strong surface cold front comes in ahead of a deep upper low currently in the Gulf of Alaska 50N/152W. Models continue to adjust the track of the upper low westward, now forecast on the northern OR coast Monday night, then SSE-ward through Oregon Tuesday, to NW Nevada Tuesday night. The surface cold front should therefore be slower to pass through our CWA, now estimated through SE Oregon Monday night and SW Idaho Tuesday morning. In addition, ahead of the front Sunday and especially Monday will be increasingly windy, with enough mid-level moisture for isolated late afternoon/evening thunderstorms near the ID/NV border. Pre- frontal wind and low-humidity will increase fire danger in SE Oregon, especially on Monday. Behind the cold front Tuesday will average 25 degrees cooler than Monday, but wind speeds have been slightly lowered from previous forecast. && .LONG TERM /Wednesday through Sunday/... Issued 216 AM MDT SUN MAY 24 2026 Model forecasts of the upper low have changed since last night. Last night`s models took the low across NV Wednesday and Thursday, and into Colorado Friday.

893 FXUS65 KLKN 240844 AFDLKN Area Forecast Discussion National Weather Service Elko NV 144 AM PDT Sun May 24 2026 .KEY MESSAGES... * Thunderstorms chances 10-20% this afternoon and early evening * Unseasonably warm through Memorial Day * Gusty SW winds Monday across Humboldt County * Gusty winds Tuesday across much of northern and central NV * Chance of valley rain and mountain snow Tuesday afternoon through Wednesday night && .DISCUSSION... (Today through next Sunday) WEATHER PATTERN OVERVIEW: A weak upper level trough will slide east across central and southern California today. Expect another day of above average high temperatures with 70s and 80s felt by all. Sufficient moisture and instability is expected across portions of US Highway 50 and spreading northeast towards Elko county. This will bring another afternoon of isolated thunderstorms to portions of the forecast area. The main threats will be cloud to ground lightning strikes with limited rainfall of 0.05 inches or less in the valleys. Wind gusts to 40 mph are possible with any storm. Skies will scatter out during the overnight with partial clearing expected Monday morning with overnight lows in the 40s. By Monday, an upper level low will be off the coast of the Pacific Northwest states, while the weak upper trough previously mentioned slides to the east into western Arizona. There will be isolated thunderstorms possible but signs point to a limited area of northern Elko county. Highs will continue to remain above normal with readings in the 80s. Winds will be breezy during the afternoon though some stronger gusts of 30 mph will be felt across Humboldt county. Look for winds to diminish during the overnight with lows in the 40s. On Tuesday and Wednesday, the Pacific coast low pressure system will dive to the southeast. Strong winds are expected to develop across northern and central Nevada. At this time, the strongest winds appear across central Nevada with southwest to west winds of 20 to 30 mph and gusts to 50 mph. A wind advisory may be needed for the afternoon period. Other locations in the north will see gusts to 35 mph. Rain showers are expected to develop later in the afternoon with light amounts of five hundredths or less expected. The system will continue its southeast trek during the overnight. Snow levels will remain between 6500 and 7500 feet through Wednesday morning. However, a cold frontal passage is expected during the night, switching winds to the northwest with colder air funneling in. Overnight lows will be in the 30s and 40s. By Wednesday, scattered rain and snow showers are expected over the region with highs only making it into the 50s. Thursday through Saturday, the upper trough is expected to wobble over the state through the period with cool temperatures. Highs will be in the 50s and 60s with lows in the 20s and 30s. The on and off shower activity is expected to continue across the area through this period as well. FORECAST CONFIDENCE & DEVIATIONS: Confidence remains low to moderate in the placement of convection over northern and central Nevada through Monday. High confidence continues with temperatures remaining above normal through roughly Monday. Confidence is moderate with the Tuesday system. Changes were made to the NBM PoP and weather grids for the short term to account for the possibility of dry convection expected across the area. && .AVIATION... VFR conditions are expected at all terminals today and tonight. Partly cloudy early this morning with increasing clouds this afternoon. Convection across portions of central and northeastern NV this afternoon with FL100-150. Thunderstorms chances today will be 5% for KWMC and KTPH, 10% for KBAM and KENV, with around 15% for KEKO. Outflow wind gusts from any storms that develop today could reach 40 to 50 mph. Isolated showers at KBAM KEKO and KENV may produce up to a few hundredths of an inch of rain. && .FIRE WEATHER... A Fire Weather Watch remains in effect from 12 Noon Monday through 11PM Monday evening for gusty winds and low relative humidity for Fire Weather Zone 437. Sufficient moisture and instability will be present across the central and northeastern fire zones this afternoon to bring another round of isolated dry thunderstorms (probability of ten to twenty percent). Main threats continue to be cloud to ground lightning strikes and outflow wind gusts to 50 mph. By Monday, an incoming east Pacific trough will be moving into the Pacific Northwest states, aiming to dive to the southeast across northern and central Nevada on Tuesday. However, on Monday, elevated fire conditions are expected across fire zone 437 as wind speeds gust to around 30 mph with minimum relative humidity values hovering between 10 and 15 percent. The strong winds will spread south and east Tuesday, where southwest winds 20 to 30 mph with gusts to 50 mph are possible across US Highway 50 in central Nevada. Afternoon highs will cool, though minimum relative humidity values will remain around 10 to 15 percent over the central fire zones. Look for increasing chances for valley rain showers and mountain snow showers over much of the area Tuesday night and Wednesday. High temperatures for the mid-week will cool into the 50s and 60s. && .LKN Watches/Warnings/Advisories...
