757 FXUS66 KSEW 241615 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 915 AM PDT Fri Jul 24 2026 .SYNOPSIS... An upper-level trough offshore will push inland over the weekend, bringing cooler temperatures to the area and additional chances of showers. Troughing will persist through early next week, allowing for temperatures to trend just below to near normal with continued PoPs. Drier conditions favored midweek onward. && .SHORT TERM /TODAY THROUGH SUNDAY/... The upper-level pattern can be characterized by an upper-low over the NE PAC and stout ridging centered over the SW US. At the surface, low-level onshore flow is ongoing across W WA with marine stratus this morning. Satellite imagery already indicates some scattering across portions of SW WA this morning, which will further allow the stratus to retreat back to the coast by this afternoon with help of diurnal heating. Today, subtle ridging is amplifying across the region, bringing a brief spell of above average temperatures. Interior highs are forecast to range between the upper 70s to mid 80s. Coastal areas of course cooler in the lower to mid 60s. Dry conditions again tonight but the aforementioned upper-low will begin to show signs of progression as it becomes ingested within the mean flow. Marine stratus on track to redevelop overnight into Saturday morning under continued onshore flow. Min temperatures will fall between the lower to upper 50s. The upper-low will finally move inland on Saturday as PoPs return into the forecast, primarily over the coast and mountain areas. Models have rain showers straggling into Sunday as well as upper-troughing becomes the main influence across W WA. This pattern favored onshore flow as reoccurring spells of marine stratus and slightly below-normal temps trend throughout the weekend with highs 70s. 41/62 && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... Looking forward into next week, upper level troughing remains the dominant influence across the area as several systems move down from the Gulf of Alaska. Some model solutions show the upper level high over the Four Corners region retrograding westward, which may allow conditions to trend drier and warmer towards the second half of the week. Otherwise temperatures generally remain around climatological normals. 41 && .AVIATION... Southwest flow aloft is expected over Western Washington today with an upper ridge centered east of the region and an upper trough offshore. The low level flow is onshore and will increase today. Widespread IFR/LIFR stratus across much of the lowlands will burn back toward the immediate coastline by early this afternoon. MVFR ceilings will develop most areas west of the Cascades overnight into Saturday morning. KSEA...IFR/LIFR stratus will lift and scatter toward 18Z. Increasing onshore flow will lead to a deeper marine layer tonight into Saturday morning with MVFR ceilings persisting into at least mid- afternoon Saturday. Surface winds W/SW rising to 7 to 10 knots becoming southerly tonight. 27 && .MARINE... Low level onshore flow continues today with strongest winds through the central/east Strait of Juan de Fuca - a Small Craft Advisory is in effect. A frontal system will stall offshore on Saturday then shift inland late Sunday. Another front will cross the waters on Tuesday. 33 && .FIRE WEATHER... More benign fire weather conditions expected today through early next week. The low offshore will finally make its way over the region. This will result increased onshore flow with cooler temperatures and shower chances through the weekend into the first part of next week easing fire weather concerns. Additional thunderstorms are not likely but can`t be ruled out at this time. 41 && .SEW WATCHES/WARNINGS/ADVISORIES... WA...None. PZ...Small Craft Advisory from 5 PM this afternoon to 5 AM PDT Saturday for Central U.S. Waters Strait Of Juan De Fuca- East Entrance U.S. Waters Strait Of Juan De Fuca. && $$ 793 FXUS66 KPQR 242203 AFDPQR Area Forecast Discussion National Weather Service Portland OR 303 PM PDT Fri Jul 24 2026 .SYNOPSIS...More seasonable temperatures return across the region this weekend. A passing front will being chances for light showers to the coast and Coast Range. Similar conditions persist into next week. && .DISCUSSION...Now through Thursday...A closed upper level low off the coast will open into another trough that will drop southward from the Gulf of Alaska. The axis of an upper level ridge over the Great Basin will shift eastward over the Rockies and Plains. This will allow onshore flow to strengthen, bringing a more noticeable cooling trend this weekend, along with a return to more marine influence and night/morning cloud cover. Temperatures trend slightly below normal on Saturday and closer to normal on Sunday with highs in the upper 70s to low 80s inland along with overnight lows in the 50s. A weak cold front will move onshore saturday, increasing southwesterly winds across the area and a slight chance for rain showers along the coast. Chances for precipitation are 10-30% north of Lincoln City with the highest chances over the Long Beach peninsula. QPF totals will be very light at 0.05 inches or less. Wind gusts 20-25 mph will be possible with locally higher gusts up to 30-35 mph along the coast and within the Columbia River Gorge. Looking beyond the weekend, more seasonable temperatures hang on into early next week before uncertainty increases during the middle of the week. Cluster analysis favors the ridge slowly building back into the PacNW which in turn would bring an increase in afternoon high temperatures. The NBM 10th-90th percentile shows an 8-12 degree spread for most days next week, ranging from the low to upper 80s for inland locations. There is not a signal for a major warm-up at this point. Shortwaves transiting the region within the southwesterly flow aloft may bring further chances for light precipitation, particularly along the coast, but the uncertainty in the position and timing of these features is low at this time. -19/36 && .AVIATION...Through 00z Sunday...Satellite imagery and terminal observations as of early Friday afternoon depicts VFR conditions with mostly sunny skies across the Willamette Valley, and a mix of MVFR/VFR conditions along the coast as marine clouds linger. The best clearing along the coast would be from now through 00-03z Sat. After 00-03z Sat, IFR/MVFR marine stratus completely returns to the coast. Inland terminals remain predominately VFR through the TAF period, with a 15-30% chance for MVFR stratus at any given hour between 10-16z Sat as the low level atmosphere moistens. West-southwesterly winds around 5-10 kt through this evening for most terminals, turning more southerly Saturday morning as a front approaches. Winds increase with the frontal passage Saturday afternoon with gusts up to 25 kt along the coast and up to 20 kt across the Willamette Valley. KPDX AND APPROACHES...Predominately VFR through the TAF period with a 15-30% chance for MVFR CIGs at any given hour between 10-16z Sat. Northwesterly winds under 10 kt through this evening, turning southerly and increasing near 10 kt Saturday morning. -10 && .MARINE...Weak low pressure offshore continues to support light winds under 10 kt and seas of 4-5 ft early this afternoon. As a front approaches the waters on Saturday, southerly winds will increase to 15-25 kt with gusts up to 30 kt Saturday afternoon. A Small Craft Advisory remains in effect from 8 AM through 8 PM Saturday across the waters, and from 11 AM through 8 PM Saturday at the Columbia River Bar. Seas during this time will also build slightly to 6-7 ft with a dominant northwest swell at 8-9 seconds. Behind the frontal boundary, winds quickly ease down to around 10-15 kt out of the south and seas to 4-5 ft, persisting through at midweek. Seasonable northerly flow returns Wednesday through the end of the workweek. -10/36 && .PQR WATCHES/WARNINGS/ADVISORIES... OR...None. WA...None.

Hot and dry weather continues this afternoon as a low continues to spin 200 to 300 miles off the Oregon coast. A new wild fire has developed in eastern Douglas County sometime last night and continues to burn this afternoon with some intensity. Most of this smoke will move towards the northeast and east this evening based on the wind forecasts. Gusty winds are also a concern with some spotty gusts to 45 mph east of the Cascades this afternoon. A few RAWS sites have reported wind gusts to 40 mph east of the Cascades already. We should see those increase in coverage with continued mixing and surface heating. By tonight into early Saturday morning, this surface low will be ingested by the next approaching trough and start to move into Washington. Persistent southerly and south westerly winds will cover the region into Saturday. Luckily, no fires to our southwest should mean pretty clear skies for most of us as the air is unusually dry for southern Oregon and parts of northern California. Northern Lake and Klamath Counties could be the exception to that rule. Some coastal stratus will also linger along the Oregon coast with very few clouds making it inland. The trough that kicked the low out Friday evening will push some energy into the Pacific Northwest by Sunday afternoon and evening. This keeps our area under a stronger south west flow aloft as a ridge remains situated to our east. Temperatures will remain near normal with highs in the lower 90`s here in Medford. Heading into next week, nothing really stands out weather wise as unusual. One could consider it as normal summer weather for our region with highs in lower 90`s here in Medford. Temperatures do start to trend warmer towards the end of the week based on the latest forecast. The NAEFS 500 mb percentiles do show us in the 90th percentile towards next weekend, so we`ll probably be pushing into the upper 90`s or perhaps 100 here in Medford next weekend. && .AVIATION...24/18Z TAFs...VFR will prevail through the TAF period for most locations. The exception being along the coast where IFR conditions north of Cape Blanco and LIFR conditions south of the Cape will waver on and offshore today, most persistent south of Cape Blanco. VFR should prevail for most of the day north of Cape Blanco, but since the marine layer will hover just offshore, it will be quick to return this evening. Some of this marine layer could make it into the Umpqua Basin, resulting in patchy MVFR ceilings overnight, but confidence is not high enough to include in the Roseburg TAF at this time. Expect gusty southwest to westerly winds to develop area wide around 21-23z, strongest east of the Cascades and across northern California. Winds will ease after sunset. /BR-y && .MARINE...Updated 130 PM PDT Friday, July 24, 2026...Overall, sub- advisory conditions under light south through westerly winds and seas at or below 5-6 ft are expected into early next week. South winds briefly increase late tonight through early Saturday as a dry cold front moves through the region. Winds could approach advisory criteria north of Cape Blanco, and while this will be shortlived, it could result in isolated areas of low end steep seas north of Bandon through Saturday afternoon. North winds and steep seas could return around mid-week. /BR-y && .FIRE WEATHER...Updated 230 PM PDT Friday, July 24, 2026... Ongoing dry conditions (illustrated by areas of single-digit daytime RHs) and forecast gusty winds are bringing critical fire weather concerns through the weekend. This concern will be the most constant east of the Cascades, where wind gusts of 25 to 40 mph for most areas and up to 45 mph over terrain in southern Lake and Klamath counties are expected in the afternoon and evening of today and Saturday. Areas of moderate to poor recoveries in easternmost Lake and Modoc counties are also expected overnight. A Red Flag Warning is in place for this afternoon through Saturday evening for FWZs 623, 624, 284, and 285 for gusty winds and low RHs. With winds having a more southerly orientation today, critical conditions are also expected in western Siskiyou County, including the Scott and Shasta valleys. In these areas, afternoon and evening wind gusts may reach 35 to 40 mph today. A Red Flag Warning covers FWZs 281 and parts of 280 this afternoon and evening. Winds in these areas ease somewhat on Saturday, reducing the need for a RFW but still supporting elevated concerns. While Warning criteria is not expected to be met in the Rogue and Umpqua valleys, dry daytime RHs and periods of gusty winds in the 15- 20 mph range can still present concerning conditions. Critical fire weather conditions will probably continue into Sunday east of the Cascades, and we`ve issued a fire weather watch for Sunday afternoon. Models are predicting humidities to trend slightly higher when compared to Friday and Saturday afternoon. The fire weather watch area is also smaller and covers southern sections of FWZ 624 and most of FWZ 285. -TAD/Smith && .MFR WATCHES/WARNINGS/ADVISORIES...

Breezy afternoon winds elevating fire danger in eastern Trinity, eastern Mendocino, and Lake Counties. && .DISCUSSION...A weak upper level low off the coast of the Pacific Northwest continues to slowly move northwestward. This troughing pattern will bring a deeper marine layer with elevated stratus and possibly coastal drizzle over the coming days. Interior temperatures will remain about or slightly below normal with most valley seeing high 80s to mid 90s. A weak and deep marine inversion will bring elevated stratus to the coastal areas and extend fairly far inland overnight into the Eel, Klamath, and Trinity River valleys. Coastal temperatures will moderate somewhat, but could still reach slightly above normal depending on how fast stratus erodes to the coast in the morning and early afternoon. Low to mid 60s are generally expected for the immediate coast and high 60s to low 70s are likely just a few miles inland. Should the stratus erode early, the immediate coast may see high temperatures in the high 60s to low 70s. The troughing pattern will also support breezy afternoon winds in the interior, especially in the higher terrain and channeled terrain in the afternoon. West winds could gust to 20 to 25 mph in these areas this afternoon. Relative humidity in the teens and 20s will support an elevated fire weather threat for eastern Trinity County, eastern Mendocino County, and Lake County. Relative humidity creeps upwards in the coming days, although winds will remain breezy most afternoons through early next week. /JB && .AVIATION...(18Z TAFs)...Stratus has largely eroded to the immediate coastline, through some periodic impacts of IFR ceilings are possible into the mid afternoon at the coastal terminals. A deeper marine layer is expected overnight with stratus intruding into the interior river valleys. IFR to MVFR ceilings are expected at the coastal terminals. Outside the immediate coast and river valleys, VFR conditions are expected to continue for the next 24 hours. /JB && .MARINE...Light winds continue across the waters with southerly winds being observed north of Cape Mendocino and northerlies south of the Cape. Seas are dominated by mid to long period northwesterly and southerly swells of 2 to 5 ft. Northerly winds start to increase south of Cape Mendocino Saturday night into Sunday, with sustained winds of 15 to 20 kts likely in the outer waters by Sunday evening. This pattern continues through mid next week. Wednesday, northerly winds increase again across the waters with strong breezes and steep seas expected for the outer waters. /JB && .FIRE WEATHER...Breezy westerly winds are likely starting this afternoon for the 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 RH today is forecast to be in the teens and 20s, which will bring an elevated fire weather threat. Relative humidities begin to rebound somewhat this weekend with most interior areas in eastern Trinity, northeast Mendocino, and Lake County seeing afternoon RH in the 20s with 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. /JB/MKK && .EKA WATCHES/WARNINGS/ADVISORIES... CA... None.

Updated at 1206 PM PDT Fri Jul 24 2026 - Breezy onshore winds expected each afternoon and evening through the weekend - Temperatures near seasonal averages throughout early next week - Gradual warming for the second half of next week with increasing Moderate Heatrisk potential across the interior && .SHORT TERM... Issued at 1206 PM PDT Fri Jul 24 2026 (This evening through Saturday night) Stratus has cleared to the coast and out over the Pacific this afternoon. As such, temperatures are forecast to reach the 60s to lower 70s in the west/northwest facing locations near the coast, 70s to lower 80s across the bayshore and Santa Cruz region, 80s to lower 90s across the interior, and mid-to-upper 90s across the warmest spots in the interior Central Coast. For tonight into Saturday morning, the marine layer is forecast to compress slightly to around 1,000 feet as high pressure over the Desert Southwest continues to strengthen. However, stronger winds above the marine layer will mix down and make for a difficult cloud cover forecast. That said, look for similar conditions as this morning with less of an inland extend into the interior valleys tonight. Patchy fog is also likely along the coast, in the Russian River Valley, and into Santa Rosa/Petaluma region. Looking like a rinse and repeat for Saturday and Saturday night. && .LONG TERM... Issued at 1206 PM PDT Fri Jul 24 2026 (Sunday through next Thursday) The ridge over the Southwest is forecast to strengthen into early next week as the trough off of the Pacific Northwest coast weakens slightly. This will keep a shallow marine layer in place while also allowing for a slight warming trend across the interior into early next week. The ridge over the Southwest looks to expand westward into southern California allowing for additional warming across the interior mid-to-late next week. Given the shallow marine layer forecast to remain intact, expecting typical ebb and flow of stratus returning to the coast late in the evening and into the valleys overnight. Stratus will retreat to the coast by mid-to-late morning each day. There is the potential by late next week to see more widespread Moderate HeatRisk across the interior. && .AVIATION... (18Z TAFS) Issued at 1037 AM PDT Fri Jul 24 2026 Outside of HAF, VFR is anticipated to prevail this afternoon at all terminals. Stratus continues to erode even across the San Mateo peninsula and there`s some confidence that cigs will lift at HAF. Satellite imagery indicates a disorganized marine layer and this increases the degree of uncertainty with regard to the return of stratus tonight into Saturday morning. Confidence is highest that LVK, SJC, and APC. Local effects along the Russian River Valley should support the development of IFR ceilings/visibility at STS, though the duration may be shorter than the previous night. Stratus should develop along the immediate Pacific Coast between 00Z-03Z with HAF having the greatest potential for MVFR and IFR ceilings. The wind field should support MVFR to IFR ceilings at OAK, but confidence is low to medium. If the marine layer struggles to develop, VFR may prevail through the entire TAF period. Otherwise, onshore breezes will increase this afternoon, with gusts of 20-25 knots, especially HAF, APC, and OAK. Vicinity of SFO...Clouds will continue to scatter this afternoon, with VFR and winds elevating to near 20 knots. Peak wind gusts are advertised to approach 30 knots, with a reasonable worst case scenario gust forecast of 32-35 knots. Confidence in the ceiling forecast is low, and it`s possible that VFR may prevail through the entire TAF set. This seems a little too optimistic, however, and there`s enough indication that some stratus will push through the San Bruno Gap and impact the terminal near or just after sunrise Saturday (though it may be intermittent). The latest TAF set has pushed the onset time for MVFR back by a few hours. Depending on when coastal stratus develops, additional refinements to timing are likely. Winds will rebuild through the day on Saturday, but peak magnitudes are expected to be closer to 25 knots. SFO Bridge Approach...The potential to remain VFR with just a few clouds is higher compared to SFO. Otherwise, conditions will be similar to SFO. Monterey Bay Terminals...VFR currently with a delay in the return of MVFR and IFR ceilings tonight. Ceiling onset has been pushed back as there`s indication that coastal stratus may be slower to re-develop. There`s low confidence in the onset time of MVFR stratus at MRY. While MVFR stratus may arrive prior to 07Z, it is anticipated to be intermittent. There`s around a 60% chance for cigs to lower into the IFR category at MRY. The potential for IFR farther east drops down to under 50% at SNS and at this time MVFR, should it transpire, is anticipated to be the predominant flight category. VFR should make a return prior to the end of the current valid TAF set, but trends will be monitored. Otherwise, largely typical onshore breezes are forecast with speeds between 8 and 12 knots. && .MARINE... (Today through Wednesday) Issued at 1037 AM PDT Fri Jul 24 2026 Moderate to fresh northwest breezes with strong to near gale-foce gusts will continue through the weekend. Moderate wind driven seas will also prevail, resulting in potentially hazardous boating conditions, even across the portions of SF and Monterey Bays. Long period southerly swell from tropical cyclone activity will arrive tonight and persist into the beginning of next week. && .BEACHES... Issued at 830 AM PDT Fri Jul 24 2026 Hurricane Fausto in the tropical Eastern Pacific will generate a long period southwesterly swell which is forecast to reach the coastline of the San Francisco Bay Area and Central Coast this weekend. 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 water; 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!

Any new or ongoing wildfires will be capable of spreading rapidly. - Stable, cooler, and calmer conditions expected Sunday into next week. && .SYNOPSIS... Wildfire smoke continues to bring hazy skies and may keep high temperatures cooler than currently forecasted. Low relative humidity and gusty winds today and especially Saturday will result in critical fire weather conditions. Temperatures will cool into the 80s by Sunday and will stay there into early next week before gradually warming again. && .DISCUSSION... Today through Saturday: A ridge firmly in place over the western US is bringing yet another hot day to the Inland Northwest. High temperatures today will be in the mid to upper 90s with triple digit temperatures in the deeper Basin and Lewiston areas. Widespread moderate HeatRisk remains over the forecast area, so all those sensitive to heat should continue being cautious and have access to adequate cooling and hydration. A strong thermal trough will result in a breezy evening as the east-west pressure gradient across the Cascades tightens this afternoon. Areas that will see the highest wind gusts (20 to 25 mph) are the Columbia Basin, Waterville Plateau, and Okanogan Valley areas. As a result, a Red Flag Warning has been issued for these areas through late tonight due to these wind gusts combined with high temperatures and relative humidity values 10 to 20 percent. Elsewhere, expect wind gusts 10 to 15 mph. As Saturday nears, a jet streak will strengthen over the area, with 500 mb flow nearing 50 to 60 knots. Additionally, a low pressure system off the coast will usher in a dry cold front Saturday morning. This cold air advection combined with steep low level lapse rates will result in 30 to 40 kt winds at 700 mb mixing down to the surface. The drier air moving in will keep relative humidities across the Inland Northwest confined to 10 to 25 percent. Thus, a widespread Red Flag Warning has been issued from 11am to 10pm Saturday. These fire weather conditions could result in rapid fire spread with any new or ongoing fires. Additionally, with wind gusts of this magnitude, there is a risk for blowing objects, damage to small trees, and localized power outages. High temperatures will decrease by about 5 to 10 degrees between today and tomorrow, and low temperatures will decrease by about 5 degrees. Sunday onward: A series of low pressure systems will keep heights lower off the PNW coast, allowing temperatures to fall into the mid to high 80s for much of the area Sunday through Wednesday. These values are right around normal for this time of year. Onshore flow and the thermal trough will continue to bring breezy afternoons to central and eastern Washington. Dry conditions will continue through this time. By Thursday and into the beginning of next weekend, the low pressure off the PNW coast will weaken and a broad ridge forms over much of the western US. Long term and cluster guidance both favor this ridge strengthening into next weekend. This will bring a return of minimum relative humidity values in the teens, as well as keep conditions dry with little to no rainfall expected across the Inland Northwest through next weekend. The CPC reflects this, with increased chances for above normal temperatures and below normal precipitation. /AS && .AVIATION... 18Z TAFS: Expect mostly VFR conditions over the next 24 hours. Regional wildfire smoke will occasionally bring MVFR conditions, especially across the northern valleys of WA and ID. Winds will increase through the afternoon and early evening, before subsiding; gusts of 15-25 kts are possible.

Current satellite shows some fire activity down in central Oregon. Fires appear to be relatively active on the landscape today, especially those under the Red Flag Waring. Humidity in the area around the fire is in the low to mid teens and winds are from the west at about 10 mph. These conditions will persist through the rest of the day today. Other than the smoke there are no clouds over the region today with the exception of some cumulus building over the Cascades. Today will remain clear with temperatures reaching into the mid to upper 90s with isolated locations in the Basin see near 101. Models show an upper level low off the coast of the PacNW. The low has begun shift across the Cascades is bringing elevated winds across the region. NBM raw ensembles shows there to be 80-90% probabilities of sustained winds of 20-25 mph through the Gorge, foothills of the southern Blues, north central and central OR, Yakima and Kittitas Valleys. So far ground observations show the Gorge has seen gusts to 20 mph. Winds are expected to pick up a bit later in the afternoon according to the NBM Raw ensembles after 1600. Saturday raw ensembles show the same probabilities for the same locations but winds are 25-35 mph sustained. Red Flag Warning are in effect and cover the vast majority of the region. As the low continues to move onshore, gradients will tighten a bit more and winds will peak Saturday. Confidence in the winds and RHs criteria is high (80-90%) As we move into the remainder of the weekend and into next week, models show the low to eject northeastward leaving the region with a trough and dry southwest flow aloft. This will continue to usher in dry conditions and slightly cooler temperatures. Even with this slight cool of, daytime humidities will still remain critical. Winds will be a typical diurnal pattern with some isolated breezy conditions, mainly through the gaps. Nothing that warrants anything other than continue elevate fire weather concerns. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/... VFR conditions to prevail through the period. Breezy winds developing today and tomorrow is expected to keep smoke from settling at sites, so there is low confidence (20%) in smoke impacts through the period.

Hot and generally dry weather continue this weekend. Skies are mostly clear as this morning with some cumulus development in the southern portions of the CWA. We are currently seated under a sort of dry slot between an upper ridge to our east and an upper low off the PacNW. The ridge to our east is dirty with trapped moisture under it, which will lead to showers and isolated thunderstorms in portions of Mineral and Mono each afternoon this weekend per the HREF members. Main concerns with any storm will be gusty outflow winds to 35-40 mph, brief periods of heavy rain and dry lightning outside of rain cores. Furthermore, this set up allows for stronger afternoon winds compared to the last few days, especially for the Sierra Front and NE CA with gusts generally between 25-35 mph and isolated gusts up to 40-45 mph over mountain ridges. This will lead to minor impacts to aviation and recreational interests, as well as critical fire weather conditions in the aforementioned areas. More of this in the Fire Section below. Temperatures this weekend will be seasonably hot with temps in the upper 90s to around 100F in valleys of western NV and NE CA, higher elevations including Sierra communities will be in the 80s. A similar pattern continues next week with the upper high moving towards the Southern Plains, and the upper trough becoming deeper to our west, and leading to a looser the pressure gradient over our region. Therefore, typical afternoon winds return along with drier conditions, POPs below 5%, and high temperatures around 5 degrees cooler than this weekend. For the second half of the week, the upper high retrogrades back towards the Desert Southwest. Main hazard at the moment will be heat. Temperatures climb back up late next week into the upper 90s and around the triple digit mark for all valleys. There is a 75-90% chance of reaching 100F next weekend per NBM guidance if this weather pattern persists. -HC && .AVIATION... VFR conditions prevail through the next 24 hrs. Exceptions possible near KMMH and KHTH due to a 10-30% chance of -SHRA/-TSRA. Otherwise, dry weather prevails. Winds will be the main concern with W to SW gusts to 25-30 kts. Minor turbulence and LLWS is possible between 00Z and 18Z Saturday due to FL100 SW winds around 30 kts. -HC && .FIRE WEATHER... Enhanced zephyr breezes with gusts up to 35 mph (isolated gusts up to 40 mph) today through Saturday will create 3 to 6 hours of Red Flag conditions in the afternoon and evening hours across portions of northeast CA and western NV. They also overlap with the Biscar Fire and the new Macy Fire in northern Washoe County. These winds will coincide with minimum RHs of 5-15%, with overnight recoveries 20-45% over the aforementioned areas. Elevated to critical wind/RH is possible Sunday afternoon in similar areas. A Fire Weather Watch was issued to address this potential fire threat. After Sunday, high pressure with a dry airmass will move overhead, with afternoon winds returning back to our typical breezes (10-15 mph gusting 20-25 mph). -Justin && .REV Watches/Warnings/Advisories...

High temperatures are forecast to remain in the mid to upper 90s across the Sacramento Valley and San Joaquin Valley. Breezy winds are expected to develop for part of the southern Cascades and into the Burney Basin today and Saturday during the afternoon/evening hours, with gusts from 20 to 30 mph at times. These breezy winds along with low humidity will bring elevated fire weather conditions to the Burney Basin and possibly the northeast foothills today through Sunday. However, winds are expected to be lower on Sunday. High pressure will continue to dominate the synoptic pattern across the area through the extended period. The upper level ridge over the Four Corner will push back toward the west and builds over the entire WRN CONUS late next week allowing high temperatures climbing into the triple digits. With the expanding heat there will also be an increasing HeatRisk across interior northern California. && .AVIATION...VFR conditions prevail across interior NorCal TAF sites next 24 hours. Surface wind gusts up to 20 kts at northern Sacramento Valley sites from around 23z today through 06z Saturday. Delta breeze influenced areas with gusts up to 25 kts this evening.

KEY MESSAGES: - Elevated fire weather conditions (hot, dry, breezy) lasting into the weekend region-wide. - Wildfire smoke degrading air quality and reducing visibility for the next several days and likely well into next week. Western Montana and north central Idaho will remain under southwest flow aloft with high pressure to our east and low pressure to the west. This will maintain hot, dry and breezy condition through the weekend. Windy conditions are expected to peak Saturday afternoon, with widespread southwest winds gusting 20 to 30 mph. The combination of hot, dry, and breezy conditions will cause elevated fire weather concerns across the region. In addition, choppy conditions on area lakes should be anticipated for those recreating on area lakes. The southwesterly flow will also continue to transport regional smoke from fires in Oregon and Washington into the region. Air quality will be diminished at times. Forecast models are hinting at thunderstorm development as far north as Butte in southwest Montana and across Lemhi county Saturday afternoon and evening. The dry low levels of the atmosphere will set the stage for high based storms capable of very strong outflow wind gusts, possibly as high as 50 to 60 mph for localized areas. The upper level pattern changes very little for early next week, with hot, dry and smoky conditions continuing. Monsoonal moisture will remain predominantly suppressed to the south, limiting thunderstorm potential to occasional, slight chances across Lemhi County and southwest Montana. Forecast models do hint at high pressure strengthening over the area by Wednesday/Thursday, which would allow for further warming of temperatures and possibly for thicker smoke to settle into valley bottoms && .AVIATION...Breezy southwest to westerly winds will persist this afternoon through early evening across central Idaho and western Montana. Wildfire smoke aloft will continue to cause limited reductions in visibility at times, though visibility should remain at or above 6SM for the region over the next 24 hours. Expect wildfire smoke to remain through the weekend into next week. For KBTM and KSMN, thunderstorm development through 25/0300Z could produce gusty erratic outflow winds if they cross near the terminals. && .MSO WATCHES/WARNINGS/ADVISORIES...

Southwest flow aloft continues over the area with hot, dry and smoky conditions today and Saturday. Critical fire weather conditions remain through Saturday evening, with low relative humidities and breezy conditions during the afternoons. Single digit relative humidities possible across eastern OR this afternoon and much of the area Saturday afternoon as a dry slot sets up over eastern OR and southwest Idaho. Lingering monsoon moisture will slowly get eroded away by the dry slot. Scattered thunderstorms across southern Twin Falls County through this evening with gusty outflow winds up to 50 mph, and a 10 percent chance of thunderstorms over the Boise and Owyhee Mountains this evening. Westerly flow on Saturday will allow for northwest winds to develop through the Baker Valley corridor to Ontario Saturday evening and Sunday evening with gusts in exposed areas up to 40 mph. This will help to bring smoke over central OR down the Baker Valley into the Snake Basin both days as well. New large fires in eastern OR and Owyhees will also contribute to increased smoke. Temperatures cool a few degrees on Saturday and a few more on Sunday. && .LONG TERM /Monday through Friday/... High pressure aloft over the Four Corner region, and troughing off the British Columbia coast, will keep our area under southwesterly flow aloft. This troughing will help keep monsoonal moisture south and east of our area, leading to hot, dry, and breezy conditions throughout the long-term period. Late in the week the Four Corners high will begin to shift west over the Great Basin, allowing for a warming trend. Temperatures will be near normal to start the coming week, before rising to around 5 degrees above normal come Wednesday. && .AVIATION /18Z Friday through Saturday/...

(This afternoon through next Friday) WEATHER PATTERN OVERVIEW: Thunderstorms are kicking off in central Nevada and are expected to spread into the eastern part of northern Nevada over the next several hours. Very warm conditions are also present, with heat advisories in effect in northern Nevada through this evening. Above average temperatures are expected to continue through the forecast period, with highs in the 90s to very low triple digits, but the humidity is expected to decrease over the next couple days. This is due to an upper level high pressure system over the plains shifting west and cutting off the monsoonal moisture flow. This will also decrease storm chances tomorrow and end them entirely starting Sunday. The high and associated ridging are favored to stay in place through the rest of the forecast, which would keep conditions dry and warm. FORECAST CONFIDENCE & DEVIATIONS: High confidence in thunderstorms today and tomorrow, although confidence is moderate regarding areal coverage tomorrow. High confidence in above average temperatures over the next several days. Moderate confidence in the forecast past Tuesday due to model variability regarding the upper air pattern. No changes were made to NBM output. && .AVIATION...Afternoon thunderstorms will continue to impact terminals, with KEKO/KENV/KELY/KTPH in the thunderstorm zone today. As usual, thunderstorm impacts will include strong erratic winds and potential short lived visibility drops due to heavy rain. KWMC, KBAM and KTPH can also expect prevailing gusty winds up to 25KT through this evening. Otherwise, expect light winds less than 10KT and VFR conditions. && .FIRE WEATHER...Isolated to scattered thunderstorms continue today, with isolated thunderstorms tomorrow.
