930 FXUS66 KSEW 100350 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 850 PM PDT Tue Jun 9 2026 .SYNOPSIS...Showers will taper off outside of convergence zone showers and thunderstorms today, with drier and warmer conditions settling into the region through the weekend and into early next week. Areas of Moderate (Orange) HeatRisk will expand across the lowlands by Sunday and continue into Monday with pockets of Major (Red) HeatRisk possible. && .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...A frontal system moved across the region earlier today, leaving widespread breezy winds and light shower activity in its wake. A Puget Sound Convergence Zone is well underway this afternoon over Snohomish County, and has produced a few lightning strikes so far in heavier shower activity. While most other areas dry out, convergence zone activity is expected to persist overnight and will likely be stalled over Snohomish County due to breezy southwesterly winds. Wednesday will kick off a warming and drying trend across western Washington as weak high pressure passes over the region and a high pressure ridge begins to build offshore. Wednesday morning will likely feature another round of marine stratus creeping inland, with sunny skies prevailing by the afternoon. The region will see some warming, though temperatures will still peak a few degrees below normal on Wednesday in the mid to upper 60s across the lowlands. Northwesterly flow aloft will prevail on Thursday as the upper level ridge offshore to the south slowly amplifies northward. Despite a cool and cloudy morning, Thursday will bring additional warming with sunny skies in the afternoon. Highs will peak in the upper 60s to lower 70s. This will introduce widespread Minor (Yellow) HeatRisk across much of the lowlands. && .LONG TERM /FRIDAY THROUGH TUESDAY/...A warming and drying trend will continue into the weekend as an upper level ridge continues to build offshore. A thermal trough moving up the coastline will reach western Washington by late Saturday, with easterly offshore flow developing as a result on Sunday and Monday. Temperatures Sunday are on track to peak in the upper 80s to lower 90s, with even warmer conditions south and east of the Puget Sound Monday with temperatures peaking in the low to mid 90s. This will introduce widespread Moderate (Orange) HeatRisk both days, with up to a 30% to 50% chance for Major (Red) HeatRisk near the metro areas on Monday. A few locations may even break daily temperature records on Sunday and Monday. Longer range models suggest a pattern change may be on track for the middle of next week, bringing an end to the incoming heat wave. 15 && .AVIATION...A post-frontal convergence zone continues in Snohomish County this evening, wit a 20% chance of thunder remaining with this activity throughout the evening. Conditions with this convergence zone have dropped locally to MVFR/IFR at times, with cloud tops less than 20,000 ft. Showers in the southwest interior/coast have also resulted in brief drops to MVFR as they pass over the terminal. The shower activity will continue into early Wednesday morning. Breezy southwest winds also continue this afternoon, with sustained winds up to 20 kt and gusts up to 30 kt. Winds will taper down tonight into Wednesday to around 4-8 kt, with only the Strait of Juan de Fuca area remaining breezy part way into Wednesday. A few Puget Sound locations will see winds turn to the north late Wednesday afternoon (via diffluence from the strait). There remains a 40-60% of widespread MVFR ceilings redeveloping tonight and into Wednesday morning through 18-21Z (with the highest chance for LIFR/IFR conditions remain in the mountains). KSEA...VFR through tonight, with convergence zone activity remaining north of the terminal. Will remain breezy through tonight with sustained winds 15-20 kt with gusts up to 30 kt diminishing to around 4-8 kt by Wednesday morning. Potential for north winds at around 5 kt or less after 00Z Thursday. MVFR probabilities increase to 40-60% around 10Z through 20Z, before scattering out. HPR/Mazurkiewicz && .MARINE...A strong onshore push in wake of a front that went through late last night/this morning continues. Showers will continue across a majority of the waters through the evening/Wednesday morning. The only threat for thunder remains in the north Puget Sound/water areas adjacent to Whidbey Island with a convergence zone continuing into the evening. Winds remain breezy across the interior waters, with Strait of Juan de Fuca winds continuing to remain the breeziest with gale gusts through this evening into tonight. Breezy southwest winds also continue in the Puget Sound, Admiralty Inlet, and Northern Inland Waters through tonight. Diurnal pushes through the Strait of Juan de Fuca will continue through the week, although probability has decreased with the potential for small craft winds. A thermal trough building along the coast this weekend/early next week may result in periods of offshore flow. Seas at 6-8 ft today into Wednesday will decrease to 4-6 ft Thursday through the weekend/next week, with a brief increase to 6-8 ft seas Friday. HPR && .FIRE WEATHER...After some wetting rains, western Washington will see a warming and drying trend settle into the region through early next week. A thermal trough will develop offshore by late Saturday, causing winds to shift easterly offshore. This will allow fine fuels to cure, with RH dropping to near critical levels over the weekend. Larger fuels may also see drying with this heat wave. Fire weather concerns will remain elevated into the weekend and will peak on Monday, corresponding with the warmest expected day of the heat wave. The thermal trough will shift inland on Monday before potentially shifting eastward by Tuesday and allowing the region to see cooler temperatures. 15 && .SEW WATCHES/WARNINGS/ADVISORIES... WA...None. PZ...Gale Warning until 5 AM PDT Wednesday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca. Small Craft Advisory until 11 PM PDT this evening for Admiralty Inlet-Northern Inland Waters Including The San Juan Islands. Small Craft Advisory until 10 PM PDT this evening for Puget Sound and Hood Canal. && $$

450 FXUS66 KPQR 100505 AAA AFDPQR Area Forecast Discussion...UPDATED National Weather Service Portland OR 1004 PM PDT Tue Jun 9 2026 ...Updated aviation discussion... .SYNOPSIS...Cool and dry becomes hot and dry for the region as an upper level high slowly builds into the region over the next 24-48 hours. This will result in a multi- day heat event focused over the weekend and into early next week (June 13-16th). This time period will present some of the hottest temperatures we`ve seen so far this year. There is at least growing confidence in a return of cooler, closer to normal temperatures (70s/80s) by Wednesday of next week. && .SHORT TERM...Now through Thursday...The core of the upper- level trough which brought widespread rain and locally breezy conditions to much of the region has moved northeastward out of our CWA and into Washington state. Model guidance maintains broad WNW flow across the region today with diminishing shower activity and slightly cooler than normal temperatures. While this pattern can be favorable for weak thunderstorm activity, and the NBM which generally drives the base layer of our forecast suggests a 10-20% chance for thunderstorms this afternoon, deterministic CAM soundings reveal CAPE values of 100-200 j/kg and is rather shallow in nature (surface to 8,000 ft) with the CAPE pool well below charge separation level which occurs around -10 degrees C to -20 degrees C. Wednesday is the start of the next major pattern change. Upper- level troughing which has been the dominant synoptic pattern to the start of the week will continue to get slowly shoved eastward by an upper-level ridge amplifying over the eastern Pacific. As this high pressure develops and becomes the dominant synoptic feature, daytime highs are expected to warm into the mid 60s to low 70s across the inland valleys, low to upper 50s for the Cascades and mid 50s to low 60s along the coast. Thursday, looks to be very similar to Wednesday with dry conditions persisting, with daytime highs to be 5-10 degrees warmer than 24 hours prior. /42 && .LONG TERM...Friday through Tuesday...Hot and dry conditions will be well entrenched across the Pac NW. Expect daytime highs to be the hottest of the year so far. These conditions are the main driver of our weather impacts through the remainder of the week, over the weekend and into the start of next week. Friday through early next week, models and their respective ensembles are in very good agreement that an upper level ridge will continue to strengthen over the far northeastern Pacific before shifting eastward. This will result in daytime highs about 5-10 degrees warmer than normal (normal this time of year is in the 60s along the coast and Cascades and in the 70s for inland valleys). By Saturday, June 13th, the NBM probabilities for daytime highs above 90 degrees F are 20-50% for the Willamette Valley. NBM probabilities for daytime highs at or above 100 degrees F on Sunday June 14th are 15-40% and 20-70% on Monday June 15th, with the highest probabilities each day towards the northern portions (Portland/Vancouver Metro) of the Willamette Valley. Also, there is a 5-15% chance for daytime highs on June 14th and June 15th of 105 degrees F or higher for locations between Salem, OR and Kalama, WA. For reference, HeatRisk levels are as follows: Little to None, Minor, Moderate, High and Extreme. Probabilities for a Moderate HeatRisk or higher on Saturday June 13th are 85-95%, then on Sunday/Monday (June 14th and 15th) 90-99% across almost the entire region. For Major HeatRisk, there is a 55-80% probability on Sunday June 14th and 25-80% probability on June 15th (highest Portland Metro, lowest near Eugene and along the coast). At least through this period the probability for Extreme HeatRisk across the CWA is 5-15% or less. Anyone who is sensitive to heat or those who have outdoor plans should prepare for and takes steps to mitigate potential heat impacts. For those planning to seek relief by swimming in local area rivers and/or lakes to cool off, be mindful of cold water temperatures and swift currents which can become life threatening if precautions like wearing a life preserver is not taken. It`s worth noting with this upper level pattern, a thermally induced surface trough also will establish itself somewhere west of the Cascade Crest-line which could result in locally breezy winds within the Cascades and/or Willamette Valley depending on its orientation. As daytime highs increase, relative humidities will also decrease. Therefore, with conditions drying out AND the potential for gusty winds, there are increasing fire weather concerns for the latter part of this week through the start of next week. So, be aware of potential ignition sources such as chains dragging on the pavement, hot vehicle components, as well as cigarette butts as these could easily result in the ignition of dry, fine fuels. Larger fuels may not have the time to dry out, but this is a variable that is being closely monitored by State and Federal Fire Partners. By June 16/17th (Tuesday and Wednesday of next week), ensemble modeling systems do hint at the ridge finally breaking down and shifting eastward, bringing a return of relatively cooler, westerly flow. However, there`s a large degree of uncertainty as to whether this transition takes place on Tuesday or Wednesday, but at least the majority of models do push temperatures downward back into the 70s and 80s by the middle of next week as in general the 25th-75th percentiles fall in-between these two values. The latest NBM only gives the inland valleys a 10-15% chance for highs to exceed 90 degrees F on Wednesday. So, confidence is moderate to high in a return closer to normal daytime highs by the middle of next week. /42-99 && .AVIATION...Radar imagery as of late Tuesday evening depicts scattered light showers across far northwest Oregon and southwest Washington as an upper level low over the Pacific Northwest weakens and moves eastward. CIGs trend predominately VFR for most areas while coastal terminals maintain a 20-40% chance for MVFR CIGs at any given hour between 06-18z Wed. Showers should gradually decrease overnight and completely dry out by late morning Wednesday. High pressure re-builds Wednesday afternoon, leading to increasing cloud breaks and scattered high clouds by the evening. Winds generally light and south-southwesterly, turning more north-northwesterly after 18-21z Wed with high pressure. KPDX AND APPROACHES...Predominately VFR conditions through the TAF period. Showers in the area will gradually decrease overnight and dry out Wednesday morning. High-end VFR CIGs scatter out after 00- 03z Thu. -10 && .MARINE...Lingering Small Craft conditions through the late evening across all waters as winds and seas gradually subside. Seas around 8-10ft at 9-10 seconds will slowly subside toward 5-7 feet by Wednesday morning and remain there through the weekend. Westerly winds with gusts up to 25 kt will also decrease through tonight and fall below 15 kt gusts by the middle of the week. From here our focus shifts to high pressure building offshore through the remainder of the week. West winds of 10-15 kt on Wednesday evening/Thursday will become more northerly. Typical summertime northerlies lock in place from this point forward, with gusts up to 25 kt each afternoon and evening from Thursday through the weekend. This may necessitate daily Small Craft Advisories. /42 && .PQR WATCHES/WARNINGS/ADVISORIES... OR...Extreme Heat Watch from Sunday morning through Monday evening for ORZ109-111-112-120.

351 FXUS66 KMFR 100605 AFDMFR Area Forecast Discussion National Weather Service Medford OR 1105 PM PDT Tue Jun 9 2026 ...Updated the Aviation and Marine Sections... .AVIATION (06Z TAFs)... Areas of MVFR are expected along the coast north of Gold Beach, and into the Umpqua Valley through around 17Z Wednesday morning. Also, gusty north to northwest breezes on Wednesday afternoon and evening will not be quite as strong, except at the coast south of Cape Blanco where gusts will again be at 20 to 30 kt. Otherwise, VFR will persist across the area through Wednesday evening. && .MARINE...Updated 800 PM PDT Tuesday, June 9, 2026...Swell dominated seas will diminish slightly into Wednesday morning. But, by Wednesday afternoon, a thermal trough brings gusty north winds and steep wind driven seas south of Cape Blanco, except very steep seas south of Gold Beach and beyond 3 nm from shore. Steep seas are likely to spread to all areas by Thursday and last through the weekend, except for periods of gales and very steep seas south of Gold Beach. && .PREV DISCUSSION... /Issued 602 PM PDT Tue Jun 9 2026/ SYNOPSIS... Frost and freezing temperatures will cover locations east of the Cascades tonight. Temperatures will trend warmer into the weekend. Moderate heat risk will likely develop by Sunday as highs push into the lower 100`s with lows in the mid 60`s. Temperatures trend cooler by next week. DISCUSSION... Nothing on radar this afternoon, although some surface stations have reported light rain over the previous hour in northern Douglas and Coos counties. Models continue to dry things out through the evening and overnight hours as the boundary layer dries out a bit. Cooler onshore flow mixed with clearing skies will really allow temperatures to drop tonight east of the Cascades. Lows will approach the freezing mark in Klamath Falls, which has a 35% chance of lows below freezing tonight. Frost is definitely the more likely threat as Klamath Falls and Chiloquin have the highest chances of dropping below 36 tonight at 70% and 75%. Lakeview has a 50% chance while Alturas has a 60% chance of falling bellow 36. By Wednesday and Thursday, a thermal trough will set up along the southern Oregon coast with some very light 5 knot easterly to north easterly breezes around 850mb. Temperatures will continue to trend warmer both days over southern Oregon and northern California as a ridge remains well to our east. It looks like temperatures peak in Brookings during this time with highs in the upper 70`s and perhaps mid 80`s on Thursday. The theme of warming temperatures continues into Friday and the models are in pretty good agreement with 500 mb heights starting to increase over the Pacific Northwest. Things begin to diverge around Saturday and Sunday when a small set of ensembles(~25%) bring a short wave through eastern Oregon. The other set of ensembles strengthen the ridge over southern Oregon and northern California. The latest NBM run, which has now ingested the 12Z ensembles, has cooled a bit with a high of 100 here in Medford, which is 3 degrees short of the record of 103 on Sunday. However, highs near 100 with overnight lows in the mid 60`s still puts us a moderate heat risk for this weekend. Moderate heat risk affects those sensitive to heat and without access to cooling/hydration facilities. It can also impact some health systems during the heat event. Eventually, this ridge breaks down and ensembles hint at more zonal flow by Tuesday. Both the GFS and ECMWF show a well defined dry cold front pushing through Tuesday night of next week, so that will have to be something to watch. -Smith && .MFR WATCHES/WARNINGS/ADVISORIES...

678 FXUS66 KEKA 100705 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 1205 AM PDT Wed Jun 10 2026 .KEY MESSAGES... - Temperatures will warm quickly with moderate to major HeatRisk expected Thursday through the weekend. - Elevated fire weather conditions in Lake County with low afternoon relative humidity and gusty winds Wednesday through Thursday. - Breezy winds are expected along the coast Wednesday and Thursday afternoons. && .SYNOPSIS...Temperatures are expected to warm to the upper 90s to around 100 in interior valley locations by Thursday through the weekend. Breezy winds are expected along the coast each afternoon and evening through at least Thursday. High temperatures in the upper 60s to around 70 degrees can be expected along the coast, warmest possibly this weekend. && .DISCUSSION...The main story this week will be a building ridge of high pressure that will bring widespread heat to the interior portions of Northwestern California. As the heat builds, the pressure gradient will tighten over the coastal waters resulting in gale force winds just off the coast and gusty conditions in coastal locations during the afternoon and evening hours through at least Thursday and possibly Friday. This will keep temperatures a bit cooler at the coast but still 60s and potentially 70 degree temps are expected through the weekend. Interior areas will warm into the upper 90s to over 100 degrees for many valley locations, starting in the south in Mendocino and Lake counties on Thursday and Friday, spreading north into Humboldt, Del Norte, and Trinity counties Friday through the weekend. Overnight low temperatures may not cool very effectively in Lake and southern Mendocino counties Thursday and Friday, resulting in increased HeatRisk for those areas. Thus, a Heat Advisory has been issued for those specific areas on those two days. Elsewhere the HeatRisk is currently on the edge of the need for heat products into Trinity and possible interior Humboldt counties over the weekend. The heat will persist into early next week but there may be some moderation around mid next week as a trough begins to deepen over the eastern Pacific pushing the ridge axis farther east. /RPA && .AVIATION...VFR is expected to prevail over much of the area over the next 24 hours. A few clouds have been stuck on the near coastal ridges of Humboldt County and it is possible moisture may pool in the Eel River Valley north of the King Range overnight resulting in the development of stratus. If conditions are just right this stratus could then spread north toward Arcata. The TAF includes a few low clouds to account for this possibility. Otherwise the main concern will be afternoon gusty winds along the coast and in north- south oriented valley locations in Mendocino County and northwest- southeast oriented valleys in Humboldt, Del Norte, and Trinity counties during the afternoon hours. /RPA && .MARINE...North winds will continue to ramp up over the next 24-36 hours as the pressure gradient tightens over the coastal waters. Gales are expected to develop in the southern zones on Wednesday and then expand north into the northern outer waters zone Wednesday night. Very steep seas will build in response to the winds. Closer to the coast along Humboldt and Del Norte counties the fetch will be smaller and winds slightly less, so only a small craft advisory has been raised for this area. Winds will remain strong through Thursday. The thermal trough will push toward the coast on Friday allowing the orientation of the winds to shift farther north and eventually nearly completely west of the waters late in the weekend. Winds may become light out of the south near the coast as a return surge moves up the coast over the weekend. /RPA && .FIRE WEATHER...High pressure is building into the area and bringing warmer and drier conditions. Nearly 10 degrees of warming is expected on Wednesday over Tuesday with nearly a similar jump again on Thursday. Along with the warming temperatures, very dry air is expected to move in and this will lower RH each day. The ridges are expected to see poor RH recoveries by Thursday morning. This will combine with some northerly winds over many of the higher ridges. The strongest winds are expected to be in the Yolla Bolla`s and down into the higher terrain of eastern and southern Lake County. This will increase the fire danger so have issued a red flag warning for Thursday morning. Fuels are likely still marginal, but winds of 15 to 30 mph and RH expected to increase only to 20 to 40 percent is concerning enough to highlight the threat with a red flag product. Thursday afternoon RH is expected to drop into the low teens in much of the interior valleys, but the winds are expected to diminish by the afternoon so have ended the red flag warning in the morning. Modeled wind trends will be monitored to determine if an extension into Thursday afternoon is needed. && .EKA WATCHES/WARNINGS/ADVISORIES... CA...

361 FXUS66 KMTR 100735 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1235 AM PDT Wed Jun 10 2026 ...New CLIMATE... .KEY MESSAGES... Updated at 1201 AM PDT Wed Jun 10 2026 - Warm and dry weather expected today through Saturday with a moderate risk of heat-related illnesses for interior locations today and Thursday - Increased risk of sneaker waves and strong rip currents along south and southwest facing beaches through Thursday morning - Critical fire weather concerns for the interior North Bay and the East Bay Mountains late tonight into Thursday morning - Minor coastal flooding near high tide beginning this evening for low-lying Bayshore locations && .SHORT TERM... Issued at 1201 AM PDT Wed Jun 10 2026 (Today and tonight) Clear conditions will generally prevail through the night as a ridge over the eastern Pacific moves into the region, kicking off the first of several days of warm to hot temperatures across the region. High temperatures today range from the upper 80s to the middle 90s across the inland valleys, with the warmest spots reaching the triple digits, while areas near the Bays see highs in the middle 70s to middle 80s, perhaps the lower 70s near southern Monterey Bay, and the coastal regions see highs in the 60s. The interior regions will see Moderate HeatRisk develop, meaning that there is a risk for heat related illnesses among heat sensitive populations, including children, the elderly, pregnant women, people with chronic health conditions, and people who work or live outdoors without adequate shelter, cooling, or hydration. There will be some relief tonight through Thursday morning as the valleys cool to the middle 50s to lower 60s, while those in the thermal belts will see low temperatures hover in the middle 60s to lower 70s. This is also when strong north to northeast winds will develop in the interior mountains of the Bay Area, especially across the North and East Bays where peak wind gusts of 35 to 45 mph are expected across the area with gusts of 60 mph or higher possible in the ridgetops. These offshore winds will contribute to poor humidity recoveries across the area overnight, and the combination of the hot, dry, and windy conditions will result in critical fire weather conditions where any fires that start could take hold and spread rapidly. A Red Flag Warning has been issued for the North and East Bay interior mountains, to come into effect tonight at 11 PM and lasting through 9 AM Thursday. Fire weather concerns are also elevated across the eastern mountains of Santa Clara County, although the wind gusts will not be as strong. See the FIRE WEATHER section for more information. High astronomical tides, combined with around half a foot of surge driven by southerly swell and thermal expansion, will result in minor flooding in low-lying areas near the Bayshore beginning this evening, mainly around low-lying locations in the North Bay and particularly eastern Marin County, and expanding to cover the rest of the San Francisco Bayshore beginning Thursday evening. Coastal Flood Advisories will go into effect at 6 PM tonight for the North Bay, and on 7 PM Thursday for the rest of the San Francisco Bayshore. At the San Francisco tidal gauge, high tide is expected to be 0.6 ft above normal (6.58 ft MLLW) at 811 PM on Wednesday the 10th, 1.2 ft above normal (6.98 ft MLLW) at 851 PM on Thursday the 11th, and 1.5 ft above normal (7.23 ft MLLW) at 934 PM on Friday the 12th. The astronomical tide predictions will support an extension of the Coastal Flood Advisories through the weekend and into the early part of next week. As a final note, long-period southerly swell is causing an increased risk for potentially dangerous sneaker waves and rip currents. A Beach Hazards Statement is in effect for parts of the Pacific Coast. See the BEACHES section for more information. && .LONG TERM... Issued at 1201 AM PDT Wed Jun 10 2026 (Thursday through Tuesday) Thursday should be the warmest day of the week as the ridge persists across the region. Temperatures in the inland valleys will jump into the 90s to near 102, with the warmest spots going up to around 105, while the Bays see highs ranging from the 80s to the middle 90s and the coastal communities range in the middle 60s to lower 80s. A Heat Advisory will come into effect from noon to 11 PM on Thursday for the North Bay valleys and interior mountains, the Sonoma coastal range, the East bay, the Santa Clara valley and eastern mountains, and the San Francisco Bay shoreline. The current forecast shows a gradual slight cooling trend beginning on Friday, which is a little curious given the lack of an obvious large scale change to the upper level pattern. Once again, I`ve opted to bump up the temperatures slightly on Friday owing to the model diagnosis, but there are models that are trying to put marine layer influence back into the region, although how far it goes depends critically on what it can do against the high pressure system. By Saturday, an shortwave trough tries to form over northern California, which could bring us another burst of offshore flow. Considered bumping temperatures up on Saturday as well, but my confidence isn`t high enough to pull the trigger as of yet. Ensemble model cluster analysis converges on the ridge continuing to impact the state for the early part of next week as the ridge axis builds into the Pacific Northwest into southwestern Canada. Beyond that, they hint at the ridge breaking down in the middle of next week, although whether that will manifest as weaker ridging over the western US or more zonal flow is to be determined. && .AVIATION... (06Z TAFS) Issued at 936 PM PDT Tue Jun 9 2026 Widespread VFR through the TAF period. Winds are reducing across the region and look to become light overnight. A dry airmass is building into the area and will prevent chances for cloud cover and fog formation. Expect light winds to last into the late morning and early afternoon before becoming more moderate westerly winds arrive. These winds will reduce into Wednesday night. However, winds aloft over the North Bay sites look to increase into the night and turn more northerly, leading to LLWS concerns through much of that night. Vicinity of SFO...VFR through the TAF period. Winds have reduced through the late evening, and will reduce further into the night, becoming light by the mid morning. Moderate winds return Wednesday afternoon but ease again that night. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...VFR through the TAF period. Expect light winds into the night and through much of the morning. SNS sees winds increase into the mid morning while winds stay light at MRY. Breezy northwest winds return in the mid afternoon. Expect light winds to return into that night, with spotty low clouds in the Monterey Bay, but not over the terminals. && .MARINE... (Tonight through next Monday) Issued at 936 PM PDT Tue Jun 9 2026 Gale force gusts are spreading across the northern waters, with gusty northwest winds continuing across the rest of the waters, resulting in hazardous conditions for small craft. Winds and seas begin to ease by Thursday evening and are expected to stay light through the remainder of the forecast period. && .FIRE WEATHER... Issued at 750 PM PDT Tue Jun 9 2026 Hot temperatures, gusty north winds, and low humidities across the North Bay interior mountains into the Diablo Range will raise the fire weather threats late on Wednesday into Thursday, with a particular emphasis on the interior mountains of Napa County. Red Flag Warnings have been issued for the interior mountains of the North and East Bay from 11 PM Wednesday night through 9 AM Thursday morning as the greatest risk of rapid fire spread arrives. Although the strongest winds will remain within the Sacramento Valley, gusts of 30 to 40 mph are expected to spread into Napa County and the Diablo Range south through Santa Clara County, with stronger gusts of 50-60 mph possible along the Vaca Mountains along Napa County`s eastern edge. Meanwhile, daytime humidity retention will be very poor with relative humidity values as low as 10-15%, while overnight recoveries are likewise poor as RH values top out at 20-30%. Thus, fuels are expected to dry rapidly, leading to the elevated fire weather concerns. Also important to note that even with the drizzle and light rain coming through the region, wetting rains (rain totals above 0.1") are not expected, limiting any relief that will be realized for the midweek period. Elsewhere across the district, conditions remain hot and dry, but we`re not expecting winds to be as strong as they are across the interior North Bay. Remember, one less spark, one less wildfire. DialH && .BEACHES... Issued at 750 PM PDT Tue Jun 9 2026 Long period southerly swell is moving through the waters with buoy observations suggesting that a swell of around 4 to 6 feet is coming from 190 degrees, just west of due south, with a period of around 19 to 21 seconds. The long period swell will result in an increased risk of sneaker waves and strong rip currents along south and southwest facing beaches. As a result, a Beach Hazards Statement has been issued for the Pacific Coast of the North Bay, San Mateo, and Santa Cruz counties through 5 AM on Thursday. Sneaker waves will run up the beach much farther than other waves, potentially catching beachgoers by surprise and resulting in people being swept into the water. 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! DialH && .CLIMATE...

902 FXUS66 KOTX 100805 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 105 AM PDT Wed Jun 10 2026 .KEY MESSAGES... - Drier and warmer late week through weekend increasing HeatRisk. && .SYNOPSIS... A dry warming trend is expected for the rest of the week. Temperatures will be warming. Widespread 80s to low 90s are forecast by the weekend. && .DISCUSSION... Today through Friday: A high pressure center of the California coast will support a ridge building along the Pacific coastline into the Gulf of Alaska. A few lingering showers over the Idaho Panhandle will dissipate by Wednesday afternoon as the earlier Low exits the region. The gradient is slow to loosen and keeps wind in the teens through the day. Ensembles have slowed on how fast the ridge builds. It has trended the highs a milder from previous forecast. It cold be do to the a strong Low over Manitoba supporting a trough stretching over BC. But minor HeatRisk is still the main concern through the end of the week. Highs for today will be in the 60s and low 70s and 70s and low 80s for the rest of the week. Overnight lows will be in the upper 30s and 40s. Saturday through Tuesday: By early Saturday morning, the trough drops into the US. There is poor agreement on the ensembles the track. Currently it is expected to clip the North Idaho Panhandle and Northeast WA. The trough could generate light precip and isolated thunderstorm. It is the best chance of any precip through the start of next week. The north to south flow pattern with the trough will bring gusty winds of 25 to 30 mph down the Okanogan Valley late Friday night into Saturday morning. The ridge axis will move over Washington Sunday through Tuesday and continues the dry, warming trend. Minor to Moderate HeatRisk will be widespread across the Inland Northwest. By Monday, highs are expected to be in the 80 and 90s. Lows will be in the 50s. /JDC && .AVIATION... 06Z TAFs: Westerly winds will also remain gusty up to 15-20 kts overnight through Wednesday.

806 FXUS66 KPDT 100444 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 944 PM PDT Tue Jun 9 2026 .KEY MESSAGES... - Scattered mountain showers through Wednesday morning - Breezy to windy conditions through this evening, with breezy conditions Wednesday - Warmer, drier conditions Thursday through the weekend && .UPDATE... The number of observations showing strong gusts to 40 mph or more has significantly diminished and are mostly relegated to a few higher exposed ridges. Wind advisories have been cancelled. LAMP guidance shows continued breezy winds overnight blending seamlessly into the anticipated breezy conditions for Tuesday. 71/Russell && .DISCUSSION... Today through Wednesday: Showers have retreated to the mountains this afternoon as an upper trough swings into northern ID and MT. Partly cloudy to cloudy conditions are evident across much of the forecast area, though some "clear" pockets have develop across portions of central OR and the Horse Heaven Hills. Breezy winds also continue across much of the area post a cold front passage this morning, with some "exposed" stations having recorded gusts 45mph or over so far. Today, shower activity will continue across mountain areas as northwest flow aloft develops behind the trough axis exit. Weak instability will develop across far northeast OR and southeast WA late this afternoon, resulting in a slight chance (10-20%) of isolated thunderstorms. However, thunderstorm activity is expected to diminish early this evening as the trough lifts further into MT. Otherwise, widespread breezy southwest to west winds (15-25 mph with gusts up to 40 mph) will continue into this evening behind a cold front passage from earlier this morning. In the lower elevations, stronger periodic gusts to around 45 mph and sustained winds up to 30 mph will continue to impact areas of the Columbia Basin, Blue mountain foothills, and in portions of the Kittitas valley. By Wednesday, the trough will slide further east of the region while upper level ridging will develop over the northeast Pacific. Any lingering shower activity over the mountains will diminish by the late morning as a shortwave rounding the trough exits to the east and the region comes under the influence of the upper ridge offshore. Breezy to locally breezy winds will continue into Wednesday evening, but will become light Wednesday night into Thursday. Thursday through Monday: There is good agreement amongst ensemble guidance that the PacNW will be under the influence of an upper level ridge in the northeast Pacific through early next week. Conditions across the area will trend drier and warmer, with the peak of the heating corresponding with the upper level ridge axis drifting closer to the PacNW (confidence 60-70%). Per the NBM, chances of reaching 90 degrees have dropped to 15-30% for Saturday across portions of the Columbia Basin, with Sunday showing 35-60% chance, and Monday a 45-85% chance across most of our lower elevation locations. While winds would generally trend light through this period, ensemble guidance is in good agreement in locally breezy conditions developing Saturday and Sunday as a shortwave trough dives down the northern Rockies (confidence 65-70%). This would bring elevated fire weather conditions across the Columbia Basin into portions of Central OR and the OR Cascade east slopes over the weekend, with the NBM showing a 30-50% chance of critical wind/RH criteria (RH < 25% and winds > 15 mph) being met. Lawhorn/82 && .AVIATION /06Z TAFS THROUGH 06Z THURSDAY/... Breezy westerly winds will persist though the overnight hours and through most of the day Tuesday before dropping to light (under 12 knots) by Tuesday evening. Lighter winds are expected at RDM and BDN. Showers remain relegated to the mountain zones, and the terminals are likely (95% confidence) to remain in the the VFR category (visibility greater than 5 sm and ceilings above 3,000 ft) for the duration of the TAFs. && .Preliminary Point Temps/PoPs...

Afternoon breezes will be enhanced today, compared to the rest of the week, with gusts up to 30 mph. Otherwise, afternoon zephyr breezes will continue through the rest of the week, gusting up to 20-25 mph each afternoon. Mostly clear skies will prevail through the remainder of the work week with dry conditions as the ridge axis sets up off the coast of the PacNW. This will bring a warming trend, with afternoon highs reaching the mid 90s for W NV valleys and mid 80s for Sierra communities by Saturday. Widespread Moderate HeatRisk is on tap by Friday for W NV valleys, including Sierra Front communities such as Reno, Carson City, Stead, and Minden. Moderate HeatRisk also starts to creep into the Sierra around the Tahoe Basin, as well. Outdoor plans this weekend? Make sure to stay hydrated, wear sunscreen, and take breaks in the shade. Planning to be on the water? Lakes, rivers, and streams are still running cold; it is still very easy for the body to go into shock from sudden exposure to cold water. Wear a life jacket and keep an eye on children and pets while near bodies of water. -Giralte && .AVIATION... VFR conditions prevail through the next week for all terminals.

Mostly clear skies this afternoon as the upper level trough begins to fully exit the region. Near normal max temperatures continue today, with the Valley seeing highs in the mid to high 80s this afternoon. As the early-week trough shifts into the Great Basin, we`ll see winds become stronger and more northerly on Wednesday and into Thursday. As north winds increase, conditions will dry out with daytime relative humidity dropping into the single digits to teens across the Sacramento Valley with limited overnight recovery. Ensemble guidance and EFI are in good agreement with highest threat across the typical western side of the Sac Valley. Our Red Flag Warning remains in place from 11am Wednesday to 5pm Thursday, and now includes the western foothills along the central and southern Sacramento Valley (in addition to the majority of the Sacramento Valley). As critical fire weather conditions continue on Thursday, temperatures will also see significant increases as upper level ridging builds along the West Coast. Triple digit Valley highs are forecasted starting Thursday and continuing through at least the early weekend in many locations. Widespread Moderate HeatRisk is expected starting Thursday, with areas of Major HeatRisk on Friday and Saturday. To this point, we have issued a Heat Advisory for the northern and central Sacramento Valley and adjacent foothills from 11am Thursday, June 11, to 11pm Saturday, June 13. While other areas in the Valley will benefit from the Delta`s cooling influence, especially in the evening, it remains important for everyone in interior NorCal to practice heat safety! Stay cool and hydrated, and consider checking in on those more sensitive to heat. There remains some uncertainty in regards to the rate of cooling into next week, but regardless temperatures should begin to cool again slightly starting Sunday as ridging gradually flattens. && .AVIATION...

023 FXUS65 KMSO 100703 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 103 AM MDT Wed Jun 10 2026 .DISCUSSION... KEY MESSAGES: - Cool, breezy, and showery today. - Localized frost Thursday morning, mainly south of the I-90 corridor. - Breezy with scattered showers Friday-Saturday, focused on western Montana (Glacier Region) while Idaho stays dry. - Warm up early next week. Today through Thursday Morning: Periodic showers will continue today under a moist northwest flow. Expect shower coverage to increase by late morning as a disturbance drops into the Northern Rockies and combines with daytime heating-induced instability. Breezy conditions will return by mid to late morning, with widespread gusts of 20 to 30 mph and localized gusts up to 45 mph near stronger showers. High- resolution guidance limits the thunderstorm potential to a slight chance (under 20%), primarily focused from north-central Idaho southeastward into southwest Montana. Daytime temperatures will remain roughly 15 degrees below normal. Morning snow levels will range from 5,000 to 5,500 feet, bringing a few inches of accumulation to the higher terrain. Backcountry recreationists should prepare for winter-like conditions and an elevated risk of hypothermia. Showers and winds will gradually diminish after sunset, leading to partial clearing overnight. Localized valley frost is possible Thursday morning, primarily south of the I-90 corridor. The National Blend of Models (NBM) indicates a 30 to 40% probability of temperatures dropping below 35F in the Bitterroot Valley, roughly 70% in Salmon, and 40 to 50% for the higher valleys along the Continental Divide. The primary caveat to this frost potential is residual cloud cover, as uncertainty remains regarding how quickly skies will clear within the moist northwest flow. A warming and drying trend takes hold later Thursday, bringing mostly sunny skies and a return to seasonal temperatures. Friday through Early Next Week: The next weather system arrives Friday afternoon and lingers through the weekend as a weak cold front and upper-level disturbance settle south. While temperatures will only cool slightly, shower chances return, primarily across western Montana, while north-central Idaho remains generally dry. The most widespread showers and isolated thunderstorms will focus over the Glacier Region. Rainfall amounts appear light, with NBM means generally under 0.10 inches in the valleys, though up to 0.50 inches is possible across the higher terrain of Glacier. Breezy conditions will persist, with afternoon gusts reaching 20 to 25 mph each day. Looking into early next week, ensemble clusters strongly favor an unseasonably strong high pressure ridge building along the West Coast. This pattern will bring dry conditions and a significant warming trend, with temperatures climbing into the lower 80s for western Montana valleys and the lower 90s in north-central Idaho. The only exception to the dry weather will be a few isolated showers along the Continental Divide. && .AVIATION...Moist northwest flow will maintain periodic showers today, with coverage increasing by late morning as an upper-level shortwave moves through. While VFR conditions will generally prevail, brief MVFR ceiling and visibility reductions and mountain obscurations are possible within heavier showers. Widespread westerly wind gusts of 20-25 kt will develop by late morning, with localized gusts up to 40 kt possible near stronger convective showers. A slight chance (<20%) of thunderstorms exists this afternoon, primarily from north-central Idaho southeastward into southwest Montana. Showers and winds will diminish after sunset with partial clearing overnight. Patchy valley fog may develop early this morning near KSMN, with localized valley fog potential across north-central Idaho and northwest Montana Thursday morning. && .MSO WATCHES/WARNINGS/ADVISORIES...

Issued 155 PM MDT TUE JUN 9 2026 A trough that brought breezy westerly winds and isolated showers and thunderstorms this morning will continue to move east this evening. Breezy westerly winds will continue through the evening, with high terrain in the central Idaho still seeing a 20-30% chance of lingering showers through the night. Temperatures will cool down about 5-10 degrees tomorrow, with overnight lows in high terrain near freezing. This will bring isolated snow showers to the central Idaho mountains as well, with snow levels dropping to 5500-6500 feet MSL by tomorrow morning. Minimal, if any, accumulations are expected. Conditions will dry tomorrow, with breezy wind gusts up to 35-40 mph in south-central Idaho by the afternoon. As the trough moves east tomorrow, a ridge of high pressure will build over the eastern Pacific early Thursday, bringing a steady warming and drying trend through the weekend. && .LONG TERM /Friday through Tuesday/... Issued 155 PM MDT TUE JUN 9 2026 Ensemble guidance remains in excellent agreement regarding the synoptic evolution through the extended period. A broad upper- level trough will remain anchored over the Pacific Northwest, keeping southeast Oregon and southwest Idaho under a persistent cold cyclonic flow. This pattern will suppress any substantial thermodynamic warming and keep convective potential minimal, though daytime heating could trigger a few terrain- induced clouds each afternoon. The latest NBM and NWS forecast continue to exhibit their typical warm bias, significantly overestimating daytime highs given the seasonably low 500 mb heights present in the cluster analysis. Thus, temperatures throughout the long term period will remain very close to climatological normals for mid-June. Expect afternoon maximums to hover in the low 80s across the lower valleys, while the higher elevations and mountain communities peak in the upper 60s. No high-impact weather systems are anticipated through early next week. && .AVIATION /06Z Wednesday through Thursday/...

175 FXUS65 KLKN 100844 AFDLKN Area Forecast Discussion National Weather Service Elko NV 144 AM PDT Wed Jun 10 2026 .KEY MESSAGES... * Elevated fire weather conditions through Wednesday. * Fair weather and warmer temperatures are expected during the latter half of the week and into the upcoming weekend && .DISCUSSION... (Today through next Wednesday) Fair weather returns to NE Nevada as an upper level ridge builds offshore of California, and a long wave trough continues to reside over the northern plains. This pattern keeps NE Nevada under WNW flow aloft, which for us is normally a dry pattern, and this week is no exception. The main factor will be occasional shortwave troughs transiting the westerly flow over Canada and dropping into the northern Rockies. These system will act to tighten the pressure gradient over NV leading to breezy westerly to WNW winds during the afternoon. This pattern will keep winds elevated Wednesday afternoon with W-NW winds of 15 MPH to 25 MPH with gusts up to 35 MPH continuing. Thursday through next Tuesday The ridge will build slowly eastward, with heights slowly rising during the week. This will cause the pressure gradient to relax some allowing for wind speeds to drop during the afternoons to 10 MPH to 20 MPH with a few gusts up to 30 MPH possible generally out of the west. Another factor will be a slow warm-up of temperatures this week into the weekend. High temperatures look to warm from the mid 70s to mid 80s Wednesday, back into the mid 80s to mid 90s by the weekend. Overnight lows will also warm, from the low 30s to low 50s Thursday morning, rising back into the upper 40s to upper 50s by Sunday morning. Models are hinting at developing a shortwave upper trough somewhere over the NW US late Sunday into Monday of next week. Models have wavered on the location of this trough with little to no run to run consistency in either the GFS or ECMWF ensembles, and the latest is no exception, although both seem to like central Idaho this evening. Still even with the proximity of this trough, both keep NV dry while only elevating winds across the northern tier of the silver state. FORECAST CONFIDENCE & DEVIATIONS: There is high confidence for quiet, dry weather conditions with warming temperatures lasting through next weekend. && .AVIATION... VFR conditions look to be the primary flight conditions through Wednesday. Winds will remain breezy out of the W-NW during the afternoon and evening hours with gusts to 25KT to 35KT. Localized areas of BLDU for northern and central NV terminals possible through 03Z Wednesday. && .FIRE WEATHER... Elevated fire weather concerns possible over the next few days as a Winds will remain breezy Wednesday as an upper level ridge builds offshore of California, and the upper trough resides over the high plains. This will place NV in between these two features, under WNW flow aloft. This pattern will keep winds breezy Wednesday, but after Thursday the ridge will build east, allowing for the westerly winds relax a bit during the afternoons, to 10 to 20 MPH with a few gusts up to 30 MPH possible. However, this will be offset by dry conditions, and warming temperatures peeking in the mid 80s to mid 90s by the weekend. && .LKN Watches/Warnings/Advisories...
