322 FXUS66 KSEW 260326 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 826 PM PDT Sat Jul 25 2026 .SYNOPSIS... A weak frontal system will traverse the area tonight into Sunday, bringing cool and cloudy conditions as well as chances for showers. Temporary high pressure Monday before another weak front arrives Tuesday. Dry and warmer weather Wednesday into next weekend as an upper level ridge centered over the southwest builds back towards the Pacific Northwest. && .SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/... Breezy conditions continue over Puget Sound and Northern Interior this evening and should gradually taper off late Sunday morning. Mostly cloudy conditions prevail across most of the area this evening, through much of the Seattle metro and central Puget Sound remains partly cloudy. Light rain showers are being reported along the coast and Olympic Peninsula. These conditions will persist through the rest of the day today as a frontal system works it was across the area tonight. High temperatures remain on track to reach the 60s to low 70s across portions of the interior with the most sunshine. Chances of showers will continue overnight into Sunday, with the best chances remaining along the Olympic Peninsula, through also expanding into the northwest Interior during the day on Sunday as well. This will help keep temperatures unseasonably cool, with highs remaining in the low 60s on the coast, with upper 60s to near 70 across the interior, with the warmest temperatures across the southeastern portions of the area. Monday looks to warm back up closer to normal, in the 70s to near 80 with more sunshine during the day. && .LONG TERM /TUESDAY THROUGH SATURDAY/... An upper level low will remain sitting off the coast of British Columbia through the first half of the week, with another shortwave trough moving over the area on Tuesday. That will bring us another round of cooler, below-normal temperatures Tuesday as well as chances for showers and breezy winds. By Wednesday and through the end of the week, the upper level high centered over the Four Corners region will begin to expand and retrograde west towards the Pacific Northwest. Heights will rise through the end of the week. Troughing off B.C. will get pushed north, but there are the potential for a few shortwaves moving through the flow that may keep us cooler than otherwise possible. Onshore flow in the low levels will also help to keep conditions temperate with at least clouds in the morning. Temperatures generally look to remain right around or slightly below normal through the end of the week. 62 && .AVIATION... Southwest flow continues aloft with an upper level trough moving into the Pacific Northwest. Widespread VFR conditions present over W WA this evening save for along the coast, where MVFR to IFR conditions are present, even though precip along the coast has become more scattered. Deeper moisture with a frontal boundary arrives Sunday with low MVFR or occasional IFR in stratiform precipitation developing along the coast and interior areas from around KPAE northward. A period of MVFR ceilings for central/south sound terminals is also expected Sunday morning before VFR conditions resume here by mid-afternoon. KSEA...VFR ceilings are expected to continue into tonight, but confidence has increased in a period of MVFR ceilings developing 12Z- 20Z Sunday. Surface winds largely remaining S/SW 5 to 8 knots for the TAF period. 27/18 && .MARINE... A stalled front offshore will move inland Sunday into Sunday night. High pressure will build behind the front Monday. Another front will move into the area waters Tuesday with high pressure again building in behind the front Tuesday night and Wednesday. Small craft advisory winds continue to linger over the coastal waters this evening, easing below criteria tonight. Diurnal westerly pushes through the Strait of Juan de Fuca in the evenings in the middle of next week could produce small craft advisory winds. 27/18 && .FIRE WEATHER... Cooler and cloudier conditions are expected across western Washington this weekend as a weather system moves across the area. Showers will remain possible through the weekend, primarily along the coast, west slopes of the Olympics, and portions of the Northern Interior as a front moves inland on Sunday. Chances of wetting rains on Sunday are between 65-75 percent along the North coast and the west slopes of the Olympics. Another frontal system will move across the area on Tuesday, helping further mitigate fire weather concerns through the near term. Warmer and drier conditions return by late next week. However, with low level flow remaining onshore, expect good relative humidity recoveries during the overnight hours and minimum relative humidities to remain above critical thresholds at this time. 14 && .SEW WATCHES/WARNINGS/ADVISORIES...

468 FXUS66 KPQR 260502 AFDPQR Area Forecast Discussion...UPDATED National Weather Service Portland OR 1000 PM PDT Sat Jul 25 2026 ...Updated aviation discussion... .SYNOPSIS...Onshore flow will bring near average temperatures with varying degrees of morning clouds and afternoon sunshine for much of the next week. A series of weak fronts will bring notable chances for light rain and drizzle to portions of the north coast this afternoon and evening, Sunday and then again on Tuesday. && .DISCUSSION...Now through Saturday...Visible satellite imagery reveals a small low pressure moving north-northeastward off the Washington coast. Marine clouds have pushed across much of the region except across the Cascades south of Mt Hood. Doppler radar indicates light returns (rain) spreading onto the north coast this afternoon. While rain reaching the ground has been limited so far, we are expecting at least a few locations, particularly across the higher terrain of Tillamook northward to Pacific Counties to wring out a couple hundredths of an inch of rain by later tonight. While not terribly impactful, south to southwesterly winds will be the most unusual aspect of this storm system with winds currently gusting near 30-35 mph along portions of the coast and between 15-30 mph in the Willamette Valley. Winds should subside this evening as the lower atmosphere stabilizes and the wind field aloft weakens. A secondary stronger front is currently out near 130W off the Pacific Northwest coast. Models are in good agreement it will shift towards the region, but there remains quite a bit of uncertainty in how much it will hold together as it moves towards the region, and more importantly, whether or not it will push into our northwestern zones or stall offshore. At this point, there is a sharp gradient in rain chances between even northern Pacific County and southern Clatsop County on Sunday. Height fields build a touch going into Monday, which will reduce rain chances and allow for high temperatures to climb more solidly into the 80s for inland valleys. Another weak front is slated to clip the Pacific Northwest Tuesday as a shortwave trough lifts northeastward into British Columbia. Rain chances will once again most likely be limited to the far north Oregon and Washington coast, but there is a 30% chance at least some light rain reaches the Kelso/Longview area. There is a just a 10% chance that rain reaches the Portland/Vancouver area on Tuesday with rain probabilities decreasing even more towards Salem and Eugene. Regardless, this passing storm system will reinforce marine clouds and cooler temperatures with high temperatures likely falling several degrees on Tuesday relative to Monday. In general, ensembles are in general agreement that our 500 mb height field will increase midweek with the end result being a warming trend late in the work week. Around 30-40% of the global ensemble guidance suggests a shortwave trough will dampen the weak ridging in place late in the week and allow another weak front to graze our northwestern coastal zones around next Saturday. /Neuman && .AVIATION...Through 06z Monday...Satellite imagery and terminal observations as of late Saturday evening depicts increasing stratus across northwest Oregon following a frontal passage earlier this evening. Willamette Valley terminals currently remain VFR while CIGs remain lower along the coast with MVFR CIGs at KAST and LIFR CIGs at KAST. High confidence for these trends continuing along the coast through Sunday as onshore flow persists. For inland terminals, stratus will gradually blanket the Valley overnight as the low level atmosphere moistens. Generally expecting low-end VFR CIGs (<5 kft) across the Valley with a 20-40% chance for MVFR CIGs at any given hour between 10-17z Sun. After 17-18z Sun, increased mixing from daytime heating will help scatter out stratus and return VFR conditions across the Valley. Light and variable winds tonight <5 kt becoming more west-southwesterly and increasing to 5-10 kt Sunday afternoon. KPDX AND APPROACHES...Predominately VFR conditions with CIGs around 5 kft or less tonight. 20-30% chance for MVFR CIGs at any given hour between 10-17z Sun. Increased cloud breaks after 18z Sun. Variable winds under 5 kt tonight becoming westerly 5-8 kt Sunday afternoon. -10 && .MARINE...A weak low pressure is lifting north-northeastward off the Washington coast this afternoon. This storm system has resulted in Small Craft Advisory level wind gusts of 25 kt and steep seas across portions of the water so far today. There remains about a 10% chance of wind gusts rising briefly into the 30-35 kt range within 20 NM of the coast, but this appears less and less likely based on the latest observations and trends. Expect winds to drop below advisory level thresholds upon frontal passage. This appears most likely to occur between 4-8pm Saturday. Seas will take several hours thereafter to subside, though. Another weak front will approach the waters late Sunday into early Monday with just a 30-40% chance that the far outer waters beyond 40 NM north of Cape Falcon will see southerly wind gusts at least briefly rise into the 22-25 kt range. Another front will push towards the waters late Monday into Tuesday. While this front stands a better chance (~50-60%) of bringing southerly 22-25 kt wind gusts to all of the waters north of Cape Falcon, the probability those winds extend as far south as Cape Foulweather is just 10-20%. Winds appear likely to return to a more typical Summertime northerly wind pattern during the latter half of next week. There is a 30-40% chance another weak front moves towards the Pacific Northwest and turns winds southerly next Saturday-ish. Once we get past the steep seas of today, seas will generally be in the 3-5 ft range for much of the next week unless some of the stronger wind scenarios mentioned above come to fruition. /Neuman && .PQR WATCHES/WARNINGS/ADVISORIES...

483 FXUS66 KMFR 260820 AFDMFR Area Forecast Discussion National Weather Service Medford OR 120 AM PDT Sun Jul 26 2026 .KEY MESSAGES... * Critical fire weather conditions are expected this afternoon and evening for southwest Klamath, southern Lake and Modoc counties due to gusty winds and low daytime humidities. * Wildfire smoke will remain generally northeast of the area today except for areas of smoke moving into northern and eastern Lake county late in the day and into Sunday night. * High temperatures will remain near normal before warming into the upper 90`s for some areas Friday. * Dry weather persists next week. && .DISCUSSION... An upper trough is located to the northwest over the Gulf of Alaska with a high pressure ridge inland, centered to the southeast across the four corners region and southern Plains. With this pattern we will remain under south west to westerly flow. Low clouds present along the coast and into portions of the Umpqua Basin will gradually clear late this morning and this afternoon. Near normal temperatures are expected across the area today. Gusty afternoon/evening winds are expected across inland areas, with strongest winds east of the Cascades. The combination of gusty winds and low daytime humidity is expected to bring critical fire weather conditions for portions of southwest Klamath, southern Lake and Modoc counties. (Please see the fire weather discussion below for detail). On Monday, a short wave trough will move into northern California. However, expect continued dry weather. Another short wave trough will move into the area from the northwest on Tuesday. This may result in a slight increase in winds with afternoon breezy to gusty winds across the region (with gusts up to 20 and 25 mph). This pattern continues through Friday with an upper trough remaining over the Gulf of Alaska and weak shortwaves move across the region. The air mass is expected to remain too dry to support thunderstorms during this period. Temperatures will gradually trend warmer through Friday. High temperatures peak on Friday with highs expected in the 90s for most areas. High temperatures are forecast in the upper 90s for valleys in Jackson, Josephine and western/central Siskiyou counties and in the low to mid 90s for most other inland valleys. Then, the upper trough in the Gulf of Alaska will move eastwards Friday evening through Saturday. A cold front will move towards the area but is expected to weaken before in moves inland. So, expect continued dry weather. Although, light drizzle is possible along the coast. && .AVIATION...26/06Z TAFs...Similar conditions are expected tonight compared to last night. Marine layer will be fairly deep along the coast, so expect MVFR there, including at North Bend, but also areas of IFR. Since the marine layer will be deeper, it is expected to develop in the Umpqua Basin during the overnight (some is already forming to the north around Cottage Grove) with MVFR ceilings most likely. Conditions should clear to VFR later Sunday morning/early Sunday afternoon for both Roseburg and North Bend. We don`t think the marine layer will be deep enough to push over the Umpqua Divide, so we are expecting VFR conditions at Medford. Klamath Falls will also have VFR for the next 24 hours. Inland TAF sites will also continue to see diurnal winds with enhanced breezes Sunday afternoon. -Spilde && .MARINE...Updated 1230 PM PDT Saturday, July 25, 2026...Overall, for the next several days, sub-advisory conditions under light south through westerly winds and low seas are expected. Seas will be a mix of fresh short period northwest swell and low long period south swell. North winds and steep seas could return Wednesday afternoon when small craft conditions are possible across nearly all waters. && .FIRE WEATHER...Updated 200 AM PDT Sunday, July 26, 2026... Ongoing dry conditions with low daytime RH and forecast gusty winds will continue to bring critical fire weather concerns through Sunday. This main area of concern is east of the Cascades across southwest Klamath, southern Lake and Modoc counties, where humidities of 8 to 15 percent and wind gusts of 25 to 30 mph are expected with up to 35 mph over higher terrain this afternoon and evening. A Red Flag Warning is in place this afternoon and evening for FWZs 624 and 285 for gusty winds and low RHs. Winds will be gusty in other portions of the forecast area, although the higher humidities are keeping the fire weather risk lower in those areas. In any case, it will still be a gusty day across the forecast area with gusts of 15 to 20 mph common around the region. Monday, winds trend slightly lower with continued low RHs in the afternoons/early evenings for most inland areas (except for higher humidities in the Umpqua). A weak disturbance is forecast to move over the area on Tuesday but expect continued dry weather with slightly higher daytime RHs and breezy to locally gusty afternoon/evening winds. && .MFR WATCHES/WARNINGS/ADVISORIES... OR...Red Flag Warning from 1 PM this afternoon to 8 PM PDT this evening for ORZ624. CA...Red Flag Warning from 1 PM this afternoon to 8 PM PDT this evening for CAZ285.

788 FXUS66 KEKA 260833 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 133 AM PDT Sun Jul 26 2026 .KEY MESSAGES... * Moderate risk for sneaker waves along the Lost Coast and Mendocino Coast through Wednesday. * Elevated fire danger through Tuesday for interior areas due to breezy afternoon winds. * Near to slightly below normal interior temperatures expected through the middle of next week. * Coastal stratus likely to form each night and clear each afternoon through at least the middle of next week. * Hot interior temperatures likely late next week. && .SYNOPSIS...Near to slightly below normal temperatures likely for the interior areas, while near to slightly above normal coastal temperatures are likely for the coastal areas for the coming days. Breezy afternoon winds elevate fire danger in eastern Trinity, eastern Mendocino, and Lake counties. Hot interior temperatures return late next week. && .DISCUSSION...The weak marine inversion and light nearshore winds allowed coastal temperatures to remain above normal with the immediate coast observing mid 60s to low 70s, and tying a record at WFO EKA on Woodly Island. Winds offshore slightly increase and turn more northerly, which could knock coastal temperatures back towards normal (low to mid 60s); however, the weak marine inversion remains in place through mid next week. The Mendocino Coast will see breezier afternoon winds which will support closer to normal temperatures. The troughing pattern has also brought breezy afternoon winds of 20 to 25 mph in the interior areas, mainly in the higher elevations and channeled terrain (such as Clear Lake and the Trinity River valley). Low afternoon relative humidities in Trinity, eastern Mendocino, and Lake Counties along with these winds brings an elevated fire weather threat. There is high confidence in high pressure rebuilding over the area late next week. NBM is showing moderate to high probabilities for high temperatures in the triple digits for most interior valleys Friday into the weekend. JB/JJW && .AVIATION...(06Z TAFS)..The low level inversion will remain at a weakened state while broad NE Pacific troughing deepens the marine layer slightly. The setup is not favorable for long duration shallow stratus and visibility obscurations; however, soundings show a very shallow saturated layer below the deepened ceiling. MVFR to IFR levels are probable, though statistical guidance (MOS) introduces some brief fog and more solid coverage of LIFR ceilings. Given the mixed signals, there is low confidence on what layer will largely persist. The weak inversion is expected to allow for another day of full clearing Sunday afternoon. /JJW && .MARINE...The sea state is dominated by a small 3 to 4 foot long period southerly swell and some small mid period westerly and northerly swells. A second reinforcing long period southerly swell will arrive Tuesday. Winds will remain very light, only up to 4 to 8 kts Sunday afternoon north of Cape Mendocino. South of the cape, northerly winds of 10 to 15 kts, and locally up to 20 kts around the cape will develop thru Sunday afternoon. The southern zones will continue to see slightly higher winds Monday before the northerlies trend higher in all waters starting Tuesday. Localized areas of gale conditions will develop in the expansion fan around Cape Mendocino. /JJW && .FIRE WEATHER...Breezy westerly winds will continue in the afternoons for interior areas and may be particularly breezy with gusts of 20 to 25 mph over the ridges and channeled terrain in eastern Trinity, northeast Mendocino, and Lake Counties. Afternoon relative humidities remain low in these areas with minimum values in the teens and 20s. Outside the higher elevations of Lake County, which has been observing moderate to poor overnight recoveries, most areas are likely to see good overnight recoveries. This pattern continues through at least mid next week with only minor fluctuations in wind and RH each day. Closer to the coast, a deep marine layer will bring high RH and perhaps stratus and/or fog into the river valleys. Afternoon RH ranges from 70s to 80s at the immediate coast to 30s and 40s in interior Humboldt, Del Norte, and western Mendocino Counties. Hot temperatures return late next week. /JB && .BEACH HAZARDS...A long period southerly swell, up to 22 seconds, has built in from tropical systems in the Eastern Pacific. A second reinforcing long period southerly swell will arrive Tuesday. These energetic swells will bring a low to moderate risk of sneaker waves that would be most hazardous on steep, south and southwest facing beaches along the Lost Coast and Mendocino Coast. Sneaker waves are a unique hazard, with up to 30 minutes between waves. Large, unexpected waves can sweep across the beach without warning, sweeping people into the sea from rocks, jetties, and beaches. These sneaker waves can also move large objects such as logs, crushing anyone caught underneath. Even ankle to knee deep water can knock you down and drag you out when a sneaker wave hits. Pay attention and stay above the high water line and any wet sand to stay safe. If the ground is wet, waves have surged there recently. Stay safe and never turn your back on the ocean! /JJW && .EKA WATCHES/WARNINGS/ADVISORIES... CA... Beach Hazards Statement through Wednesday afternoon for CAZ104-109.

581 FXUS66 KMTR 260733 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1233 AM PDT Sun Jul 26 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1232 AM PDT Sun Jul 26 2026 - Breezy onshore winds expected each afternoon and evening through early in the week - Temperatures near seasonal averages through the first half of the week - Gradual warming starting midweek, with increasing Moderate HeatRisk for interior locations heading into the weekend && .SHORT TERM... Issued at 1232 AM PDT Sun Jul 26 2026 (Today and tonight) Upper level troughing holds over the eastern Pacific and into the PacNW today, slowly meandering eastward. Satellite trends show stratus forming along portions of the northern California coast, which should bring stratus to most coastal locations and down into the Monterey Bay. Uncertainty remains on how deep the marine layer gets tonight, though current thinking is it`ll be between 500- 1000ft. Any stratus that forms tonight should retreat to the coast by mid to late morning with mainly sunny skies prevailing. && .LONG TERM... Issued at 1232 AM PDT Sun Jul 26 2026 (Monday through Saturday) We will remain under an elongated trough through early to midweek, leading to typical summer like days. Look for seasonal temperatures, breezy onshore winds each afternoon and evening, and the return of stratus. The marine layer should get to about 1000ft for the next few nights, with it a 500-1000ft marine layer by midweek for those along the coast. This is when we start to see high pressure over the Desert Soutwest build into southern and central California and begin pushing the trough and making it a bit more compact. Onshore flow should help moderate temperatures near the coast, as we go from a trough to quasi-zonal flow. Warmer temperatures will be expected inland, but overall temperatures will continue to increase as we head into the weekend. Widespread Moderate HeatRisk continues to look likely for interior locations. && .AVIATION... (06Z TAFS) Issued at 938 PM PDT Sat Jul 25 2026 Currently VFR (except for HAF which is IFR) with stratus beginning to develop along the coast. Stratus will continue to expand through the night with high confidence in the coastal terminals becoming IFR. With a compressed marine layer around 1,100 ft, ceilings will likely be IFR/low-end MVFR and difficult to penetrate inland. Moderate confidence on it reaching bayshore terminals, low confidence on it reaching interior terminals. Widespread VFR is expected by tomorrow afternoon. Diurnal winds will prevail. Vicinity of SFO...Currently VFR with westerly flow. Moderate (60%) confidence on a ceiling returning tonight, likely IFR/low-end MVFR, with VFR by late morning. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...Currently VFR with southerly flow at MRY and VFR with northwesterly flow at SNS. High (80%) confidence on ceilings returning tonight, likely IFR, with VFR by tomorrow afternoon. && .MARINE... (Tonight through next Friday) Issued at 938 PM PDT Sat Jul 25 2026 Fresh to strong northwesterly breezes across the inner and outer waters and the afternoon sea breeze will result in hazardous conditions for small craft through Wednesday. Frequent gale force gusts are expected along the coastal jet region of Big Sur. Moderate seas will prevail through Tuesday, building to become rough in the outer waters Wednesday. Long period southerly swell from distant tropical cyclones in the Eastern Pacific Ocean will continue. && .BEACHES... Issued at 911 AM PDT Sat Jul 25 2026 Tropical cyclones in the Eastern Pacific are generating a long- period southwesterly swell which has reached the coastline of the San Francisco Bay Area and Central Coast. As such, sneaker waves and strong rip currents are the primary concerns. However, breaking waves can reach up to 10 feet along some south and southwest facing beaches and break points (like Santa Cruz, Pacifica, and parts of Stinson or Ocean Beach). Sneaker waves can have 20+ minutes in between the larger sets (breaking waves) with significant "flat/calm looking" times between them. This can potentially catch beachgoers by surprise and resulting in people being swept into the cold turbulent ocean; hence the name "sneaker". Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean! The Beach Hazards Statement has been extended through Wednesday afternoon for all beaches along the Pacific Coast. RGass && .MTR WATCHES/WARNINGS/ADVISORIES...

293 FXUS66 KOTX 260714 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1214 AM PDT Sun Jul 26 2026 .KEY MESSAGES... - Periodic breezy winds with seasonably normal temperatures Sunday through Wednesday. Elevated to critical fire weather conditions Tuesday for central WA. - Above normal temperatures return by Thursday with highs in the 90s. && .SYNOPSIS... Breezy winds will linger into Sunday through Wednesday across Central Washington, resulting in elevated to critical fire weather conditions. Temperatures will cool to near seasonal normals in the 80s. Above normal temperatures return later next week in the 90s with continued dry conditions. && .DISCUSSION... Sunday through Monday: In the wake of the cold front that passed through yesterday, the Inland Northwest will remain between troughing off the PNW coast and a strong ridge over the central US for the next couple days. This will enhance the thermal gradient across the Cascades each afternoon and evening, bringing breezy to gusty conditions across central and eastern Washington. Areas that will see the highest winds (25 to 30 mph) each day include the Okanogan Valley, Waterville Plateau, and Columbia Basin. When coupled with minimum relative humidity values 15 to 25 percent each evening, elevated to critical fire weather conditions are expected in these areas. This will result in rapid fire spread for both new and existing fires. Temperatures today and Monday will cool to the mid to high 80s, right around normal for this time of year, resulting in only Minor HeatRisk. Tuesday: On Tuesday, the low off the PNW coast will move inland, ushering another dry cold front through the forecast area. This will bring widespread wind gusts 15 to 20 mph, and more localized higher wind gusts 25 to 35 mph in the usual areas: Cascade gaps, Waterville Plateau, Columbia Basin, and Okanogan Valley areas. With relative humidity values remaining low at 15 to 25 percent, this will bring critical fire weather conditions back to these areas. Temperatures on Tuesday remain near normal. Wednesday through Friday: Once the cold front moves through, the region will again be in between offshore troughing and a ridge over the central US. The thermal pressure gradient will be weaker than on Monday and Tuesday, bringing breezy winds 10 to 20 mph to central and eastern Washington. However, the ridge will begin moving westward and strengthening during the last two days of the work week, resulting in increasing temperatures and a return to the 90s on Friday. This will also increase the thermal pressure gradient, bringing slightly higher wind gusts near 25 mph throughout the basin, Waterville Plateau, and Okanogan Valley areas. Next weekend: Long-term guidance and clusters both favor another trough moving across the region and ushering yet another dry cold front through the area on Saturday. This will again increase winds across the entire forecast area, and relative humidity values remaining low will result in another round of critical fire weather conditions. Throughout the week into next weekend, chances for precipitation remain at or near zero percent, with PWAT values expected to remain only at 70 percent of normal (0.5 to 0.7 inches). /AS && .AVIATION... 06Z TAFS: VFR conditions will mostly prevail through the forecast period. Winds continue to be out of the south/southwest, with GEG, SFF, and PUW still experiencing gusts 10kts or more. By around 09Z, winds across each TAF site will relax to less than 10kts. Smoke impacts from current fires appear to be minimal but any new fires may bring reduced visibilities to any of the TAF sites, briefly dropping sites to MVFR. Breezy winds return around 20Z, with highest wind gusts 15-20kts expected at GEG, SFF, and COE. By around 02-04Z, winds will relax to below 10kts. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Low confidence in smoke reducing visibility at the TAF sites. This is the most impactful alternate scenario. Should smoke reduce visibilities, amendments will be issued. Moderate confidence in the timing of winds weakening. ----------------------- 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...

Satellite imagery this afternoon shows mostly clear skies with elongated plumes of smoke coming from fires in central and eastern OR. Cumulus have also been noted developing within some the plumes emanating from the Shingle, Crosswhite, and Bench fires. Otherwise water vapor imagery shows a shortwave coming ashore in WA. At the surface, westerly winds are increasing across the forecast area as the shortwave and an accompanying cold front approach the forecast area. Today, winds will increase (15-25mph with gusts 30-45mph) across the forecast area as the shortwave and cold front push inland. The cold front boundary will continue to push east today, with winds shifting from southwest to west this afternoon, then shifting again to the northwest late this evening. Winds through the Cascade gaps will stay their usual direction (west to northwest). These increasing winds will also overlap with low relative humidities in the lower elevations, resulting in critical fire weather conditions through this evening. Winds will remain breezy post the cold front passage tomorrow, but will be lighter (10-20 mph with gusts up to 35mph). Dry conditions will remain across the region, but will increase slightly as afternoon temperatures lower slightly. While fire weather conditions will remain elevated, localized areas of central OR and the lower elevations in the eastern mountains may see critical fire weather conditions develop for a few hours in the afternoon (confidence 55-70%). Through Friday, there is great agreement that the forecast area will remain between upper level troughing in the northeast Pacific and an upper level ridge over central and southwest CONUS. This will place a dry, southwest flow aloft over the PacNW that will keep temperatures near seasonable. That said, a weak shortwave and cold front boundary will lift across northwest WA, producing another round of breezy conditions and slight cool down. The most recent run of the NBM shows low probabilities (<20%) of wind/RH overlap Tuesday afternoon. That said, confidence is mod- high that elevated fire weather conditions will be present across the lower elevations. Thursday through Friday, there is good agreement that while the forecast area remains under southwest flow aloft, upper level ridging over the central CONUS will gradually retrograde west, which will allow temperatures to warm from the upper 80s to low 90s into the mid to upper 90s across the forecast area (confidence 60-75%).

332 FXUS65 KREV 260820 AFDREV Area Forecast Discussion National Weather Service Reno NV 120 AM PDT Sun Jul 26 2026 .KEY MESSAGES... * Gusty winds will pose fire and lake recreation impacts this afternoon. Typical afternoon breezes return after today. * Seasonably hot and dry weather prevails through midweek with very low chances of showers and thunderstorms throughout the week. * Hotter temperatures are expected late this week into next weekend, increasing the potential for heat impacts. && .DISCUSSION... A seasonably hot, dry, and breezy weather pattern remains in place through midweek as strong high pressure to the east directs dry, southwesterly flow into the region. W/SW gusts of 25-35 mph will once again mix down to areas from the Oregon border south along the Sierra Front today, renewing fire and lake recreation impacts this afternoon. After today, winds weaken to a more typical 20-30 mph each afternoon. Otherwise, typical July heat continues through Tuesday with daytime highs in the 80s to mid-90s. Moisture aloft continues to be displaced east of the region today, but forecast soundings suggest there may be just enough residual moisture to support isolated showers/virga in S Mono and Mineral counties this afternoon. Thunderstorms are not expected as this moisture is likely too shallow. The upcoming week is favored to be a rather dry one as chances of showers and thunderstorms stay below 5% through next weekend. A couple of weak trough passages around midweek may posses enough lift/moisture to yield a stray shower or storm near the Oregon border, but there is much higher confidence in dry weather prevailing this week. A warming trend remains on track for the second half of the week as high pressure retrogrades towards the Four Corners region. Triple digit heat may return to lower elevations valleys as early as Wednesday with higher chances of 100F+ heat Thursday into next weekend. While shy of record-breaking, these temperatures will increase the potential for heat impacts to health as we head into August so be sure to make plans accordingly. -Salas && .AVIATION... Gusty W/SW winds and minor LLWS impacts remain the primary concern today and Monday with surface gusts reaching 20-30 kts each afternoon. Otherwise, widespread VFR conditions prevail over the next several days. Triple digit heat may return to western Nevada terminals towards the end of the week, increasing the potential of density altitude impacts. -Salas && .FIRE WEATHER... A brief 2-5 hour overlap of marginally critical W/SW winds (sustained 10-20 mph, gusts of 30-35 mph) and RH reductions to 5-15% should unfold this afternoon across far NE California and NW Nevada. A Red Flag Warning will be in effect from 1 PM until 9 PM PDT today for these areas. Nighttime recoveries will be moderate to poor in these areas each night, which may allow fires to actively burn overnight -- especially in W NV where RH struggles to exceed 20-30%. Winds weaken to near/sub-critical levels after today, but will still become breezy each afternoon with gusts of 20-30 mph. Along with hot and dry conditions, these winds may briefly support areas of elevated fire weather conditions each afternoon this week. A warming and drying trend is favored late this week into next weekend, yielding 90F and 100F+ heat with teen and single digit min RH, and poor nighttime recoveries spreading into higher elevations. Some notable potential impacts from this include: drier vegetation -- especially heavier fuels, heat stress/exhaustion to fire suppression personnel, and deeper vertical plume growth on new/existing fires. -Salas && .REV Watches/Warnings/Advisories...

925 FXUS66 KSTO 251942 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 1242 PM PDT Sat Jul 25 2026 .KEY MESSAGES... - Elevated fire weather conditions today and Sunday within the Burney Basin and the northeast foothills due to low relative humidity and breezy southwesterly to westerly winds. - Increasing heat across interior northern California late next week, with Moderate HeatRisk. && .DISCUSSION... Seasonable temperatures continue through early next week, with highs in the 90s across the Valley. Warmest conditions in the northern Sacramento Valley. Winds will be breezy out of the southwest to west, along with onshore flow today and tomorrow. Winds gust up to 25mph out of the southwest to west across the northeast foothills, Burney Basin, and areas in the northern Sacramento Valley towards the higher terrain. Minimum RH values today and tomorrow drop into the teens to potential single digits in the Burney Basin and northeastern Foothills bringing elevated fire weather concerns through tomorrow. The driest conditions will be this afternoon and evening. None the less, we will continue to headline the Elevated Fire Weather Concerns for the Burney Basin and northeastern Foothills through tomorrow due to the low RH combined with the breezy southwesterly to westerly winds. Looking at the synoptic pattern aloft, the ridge of high pressure dominating over central CONUS will start to push back toward the southwestern United States early to mid next week helping to dry conditions out further and increase our temperatures. There is increasing confidence in widespread moderate HeatRisk end of next week and into the first couple days of August, with probabilities of exceeding 100F around 50-70 percent across the Valley. We will be monitoring the heat as we move through the week and determine the need for any heat related products by the end of the week and into the first days of August. We will also be monitoring the low RH values that come along with the heat across the area. && .AVIATION... VFR conditions continue through the TAF period, with breezy surface winds through the afternoon and evening hours. A few gusts to 20kts will be possible for the TAF sites through 04z. Otherwise, winds go light overnight with a few clouds to clear skies. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$

926 FXUS65 KMSO 260736 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 136 AM MDT Sun Jul 26 2026 .DISCUSSION... KEY MESSAGES: - Hot, dry, and smoky conditions continue through this week. - Even hotter, drier, and windy conditions to end next week. - Potential cool down to near average temperatures next weekend, though it remains dry. Our current pattern of high pressure ridge to our east and the Northern Rockies under southwest flow will remain unchanged for the time being. Expect very warm and dry days, unstable atmosphere, and smokey conditions. Our region looks to be cut off from monsoonal flow but isolated thunderstorms during the afternoons in southwest MT and Lemhi County ID will be possible but low probability. The biggest concern in the short term will be degrading air quality from local and regional fires. Each overnight smoke will likely filter into valleys, then during the afternoon solar heating will destabilize the atmosphere allowing for some ventilation. Unfortunately, smoke inherently stabilizes the atmosphere by blocking solar energy and limiting surface heating. Without a cold front to scour out valleys, eventually smoke will increase to the point of stabilizing valleys, degrading visibility and air quality. High resolution guidance would suggest northwest and west-central MT will be among the first valleys for this to occur over the next few days. Relief? The models are notorious for trying to breakdown high pressure ridges too quickly. Current models would suggest successive short waves and eventually ejection of the main Pacific low pressure trough flattening the ridge, could happen as early as Friday/ Saturday. Last night I wrote Thursday/ Friday, so the models are already trying to delay ridge breakdown. When breakdown of the ridge does happen, this would likely lead to a period of heightened fire weather due to an increase in winds. Additionally, a cooling of temperatures and cleaning out of smoke from valleys would also be logical outcomes. && .AVIATION...With a strong ridge over the region, the main aviation impacts will be from wildfire smoke both regionally and locally. Impacts from the smoke have been minimal at area terminals, with visibility getting as low as 5SM in the early morning hours, but generally improving through the day. With the ridge being stationary, we expect this pattern to continue through most of the coming week. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None. ID...None. && $$

Issued 244 PM MDT SAT JUL 25 2026 Southwest flow aloft continues over the area with hot, dry and smoky conditions today. Critical fire weather conditions remain through this evening, with low relative humidities and breezy conditions. Relative humidities are below 5% in some areas this afternoon. Enough lingering moisture over the Owyhees and northern NV will be enough to trigger isolated thunderstorms over far southwest ID this afternoon and the threat will continue overnight as a weak wave moves northeast. A slight chance of thunderstorms overnight over southwest ID mainly SE of a line from Boise to Stanley, ID. Drier air moves into the area on Sunday with slightly cooler temperatures and continued low humidities. Winds aloft will be weaker Sunday and Monday so afternoon breezes will be weaker. && .LONG TERM /Tuesday through Saturday/... Issued 244 PM MDT SAT JUL 25 2026 An upper level four corners high, and a trough over British Columbia, will keep our area under southwesterly flow aloft. Monsoonal moisture will remain south and east of our area in this pattern, leading to a hot, dry, and breezy long-term period. Near (leaning above) normal temperatures will warm to around 5 degrees above normal come Thursday, as the upper-level high shifts west over the Great basin. && .AVIATION /06Z Sunday through Monday/...

181 FXUS65 KLKN 251942 AFDLKN Area Forecast Discussion National Weather Service Elko NV 1242 PM PDT Sat Jul 25 2026 .KEY MESSAGES... * Shower and storm chances through tonight for eastern portions of NV * Moderate risk of heat-related illnesses throughout Northern Nevada this afternoon * Shower and storms chances linger along eastern border through Wednesday * Above average temperatures and HeatRisk continue through the end of the forecast && .DISCUSSION... (This evening through next Friday) WEATHER PATTERN OVERVIEW: An HPC over the Four Corners region responsible for an active monsoon week over the Silver State will deepen and retrograde to the west next week. This effectively will cutoff monsoonal flow to the region (though CAPE/PW values stay robust along the eastern NV border through Wednesday) and create hazardous Heat Risk conditions across the area by end of the week. For the remainder of Saturday, radar/satellite imagery depicts cloud buildups and storms beginning to develop over Elko County this afternoon. Storm coverage is forecast to be mainly over Elko County and northern Lander, Eureka, and White Pine Counties. PW values this afternoon over those areas are ranging 0.8-1.0 inch so localized brief heavy rainfall is possible where storms form. Storm motion is relatively quick but training storm motion especially over locations previously receiving heavy rain this week will keep minor flooding concerns in the forecast for the remainder of the weekend. Other hazards with storms on Saturday include brief strong wind gusts and dangerous cloud to ground lightning. As the HPC deepens on Sunday monsoonal moisture is shunted eastward and storm chances will be confined to extreme eastern portions of Elko and White Pine Counties along the UT border. This setup will remain in place through mid week. Beyond Wednesday the HPC will continue to strengthen and retrograde back westward over the SW CONUS. This will significantly dry out the region even further ending precipitation chances in the near future. The bigger concern will be the increase in afternoon high temperatures under the dome of high pressure. Highs in the upper 90s and triple digits late week and next weekend will increase the risk of heat related illness across the area. Heat advisories and other products are most certainly possible later this week as a hot weather pattern entrenches itself over the region. FORECAST CONFIDENCE & DEVIATIONS: Typical adjustments were made to the Wind/WindGust grids as NBM normally undervalues wind speeds for hot/dry/windy conditions such as those created in NW NV today. High confidence exists in shower and storm chances over eastern NV Saturday afternoon. A combination of SST and SerpISC was used to edit hourly Wx grids this afternoon as NBM misrepresented storm chances and coverage today. Moderate confidence exists in lingering storms over the eastern border through Wednesday. Moderate confidence exists in above average temperatures and HeatRisk later this week and next weekend. && .AVIATION... VFR conditions are expected at all terminals through Sunday afternoon. -TSRA forecasted at KEKO, KELY, KBAM, and KENV will create momentary MVFR/IFR conditions along with brief gusty and erratic winds. Westerly afternoon wind gusts at all terminals will range 22-25 KTs. Gusty winds will diminish after sunset Saturday evening. && .FIRE WEATHER... Minimum RH values in zone 437 today passed critical thresholds in the latest forecast. A Red Flag Warning has been issued as a result, with winds gusting around 35 mph in that area. This criteria may be reached again tomorrow in the same area. Thunderstorm chances also continue today, with isolated storms forecast mainly in Elko County. After tomorrow, winds will be elevated to near critical but no critical fire weather conditions are expected. && .LKN Watches/Warnings/Advisories...
