178 FXUS66 KSEW 090334 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 834 PM PDT Mon Jun 8 2026 .SYNOPSIS...Cool and unsettled conditions will continue across Western Washington through Tuesday. A pattern shift toward dry and considerably warmer conditions is expected late in week as strong high pressure aloft builds into the region. && .SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...A low pressure system offshore will move into Western Washington tonight. Steadier rain along the Olympic Peninsula will continue to progress eastwards during this period, with the heaviest rain during the overnight period for Puget Sound. This will be a beneficial rain for the region, with QPF amounts ranging 1 to 2.5 inches for the Olympics and Cascades, with 0.50 to 1 inch for the majority of the lowlands. Showers will develop after the system moves through on Tuesday, with a convergence zone expected in the vicinity of Snohomish County during the afternoon. Rather marginal instability may result in a few thunderstorms, mainly associated with the CZ Tuesday PM. Otherwise, lingering showers into Tuesday night will taper off into Wednesday morning. In addition to the precipitation, south-southwest winds increase tonight through Tuesday with increasing onshore flow. Widespread wind gusts of 20 to 35 MPH - notably breezy for mid June. Localized gusts to 40 MPH also can`t be ruled out, mainly along Whidbey Island due to west winds (REFS probabilities peak around 60-70%), and also in south sound around Tacoma. Winds will subside Tuesday night. Upper level ridging will begin to build into Western Washington on Wednesday. This will result in conditions slowly drying out through the afternoon, widespread morning clouds clearing for some sunshine. Temperatures remain cooler than normal through midweek with highs in the mid 50s to mid 60s. && .LONG TERM /THURSDAY THROUGH MONDAY/...An upper level ridge will continue to build over the NE Pacific Thursday and Friday resulting in dry conditions and a warming trend for Western Washington. The ridge axis will remain over the NE Pacific through Friday with weak troughing over the intermountain West. Temperatures on Thursday will reach the 70s for most locations away from the water, with low 80s for south Sound by Friday. This results in widespread minor HeatRisk by Friday. Ensembles are in general agreement of the upper ridge building further over the NE Pacific Saturday, with the ridge axis shifting towards the Pacific Northwest by Sunday into Monday. Thermal troughing that develops will allow for offshore by late Saturday and continuing into early next week. Temperatures are expected to be the warmest they`ve been so far this season. Highs by Sunday and Monday will range in the 80s into the mid 90s for some locations. Widespread Moderate HeatRisk is expected Saturday through Monday, with the potential for Major HeatRisk Sunday and Monday as well, particularly away from the water. It will be important to be aware and prepare for hotter temperatures going into the weekend. JD && .AVIATION...South to southwesterly flow aloft becoming westerly tonight as a surface low moves into the area and brings widespread rain with it. MVFR cigs have already developed along the coast this afternoon, with MVFR ceilings spreading into the interior early this evening and throughout the overnight. Will also see vsby reductions in areas with heavier stratiform rain, ranging from 4-6 statue miles at times. Stratiform rain will continue through the evening, even with MVFR ceilings being the predominant condition, IFR conditions likely at the coast and areas along the Olympic Peninsula, with a 15-25% chance of IFR conditions developing within the interior. Light and variable winds mainly under 7 kts for the interior through this afternoon. Winds will then turn south/southwesterly this evening while increasing to 14 to 18 kts sustained, with potential gusts up to 20 to 25 kts. KSEA...MVFR cigs this evening as widespread rain has moved near the terminal. MVFR cigs continuing through Tuesday AM. Cigs may fluctuate to IFR at times tonight, particularly between 07-12z (20% chance). Within MVFR/IFR ceilings, could see vsby reductions 4-6 statue miles within heavier rain at the terminal during the evening and overnight period. Winds are expected to remain mainly W/SW this afternoon. W/SW wind speeds will increase tonight up to 14 to 18 kts sustained, with gusts up to 15 to 20 kts. Winds will remain gusty into Tuesday morning, increasing even further Tuesday afternoon with gusts up to 25 kts. JD/Mazurkiewicz && .MARINE...A surface low and associated frontal system will move onshore and weaken into tonight. Elevated southwest winds over the Coastal Waters into this evening will transition more northwest tonight into Tuesday in a post-frontal onshore flow regime. Southwest winds also increase for interior waters Tuesday morning, continuing through the afternoon. Small Craft Advisory wind gusts are expected for most waters on Tuesday due to the strengthening onshore flow. Furthermore, a strong west push through the Strait of Juan de Fuca is expected to result in gale force wind gusts for the central and eastern Strait on Tuesday. A Gale Warning has been issued for this reason. Winds slowly ease Tuesday night into Wednesday. Winds become lighter Wednesday as high pressure builds back into the Coastal Waters. Northwest winds over the Coastal Waters increase Thursday into late week as high pressure continues to build offshore. Flow will transition to offshore at times over the weekend into early next week as a thermal trough expands northwards along the coast. Seas will range between 6 to 9 feet through Tuesday. Brief 10 foot seas are possible along the central and southern outer Coastal Waters as well during this period. Seas subside to 4 to 7 feet by Wednesday and remain in this range into late week. JD && .FIRE WEATHER...The upper ridge building into the area starting Thursday and continuing into early next week will result in hot, dry conditions. Current NBM minimum RH values are running in the 20-35 percent range by next Monday across portions of the area, but lower values are entirely within the realm of possibility. If the cross Cascade gradient goes negative by Sunday, RH values may drop into the teens in the Cascades valleys and portions of the Southwest Interior. This pattern results in elevated fire weather conditions, especially Saturday through at least Monday. JD && .SEW WATCHES/WARNINGS/ADVISORIES... WA...None.

145 FXUS66 KPQR 082134 AFDPQR Area Forecast Discussion National Weather Service Portland OR 234 PM PDT Mon Jun 8 2026 .SYNOPSIS...Cool and wet to hot and dry. This is a simple, concise and accurate summation of the weather conditions as we progresses through the next 7-9 days. Tonight will remain rather soggy and cool, with a very slow warming and drying trend expected through the remainder of the week. Confidence continues to increase for a multi-day heat event in the June 12th through June 16th timeframe. Don`t get caught off guard and start preparing for heat related impacts, you`ll thank yourself later. && .SHORT TERM...Tonight through Wednesday...Cool, wet, and showery conditions will continue through the overnight hours as a upper level low moves northerly over the region. As the low moves over the region, southerly winds looks to increase which could bring isolated gusts up to 35-40 mph for inland locations from around 4PM through 10PM. Deterministic models and their ensembles remain in good agreement for broad upper level troughing to hold over the region Tuesday helping to maintain a cool and showery weather pattern. Given that more cloud breaks and slightly warmer daytime (think low to mid 60s for inland locations) highs are expected on Tuesday, general instability will also increase. Thus there is a 10-20% chance for thunderstorms across the CWA starting in the late morning through the late evening. Wednesday, is the start of the next major pattern change. The low which has been the dominant synoptic feature for the start of the week, will get slowly pushed eastward by an upper level ridge moving in from the eastern Pacific. As high pressure develops, daytime highs are expected to warm into the mid 50s to mid 60s along the coast and in the Cascades, with inland daytime highs reaching into the mid 60s to low 70s. As far as precipitation totals concerned, the bulk of the precipitation is set to end around 5 AM PDT Wednesday. QPF amounts from the deterministic NBM during this 48-hour period range generally between 0.5-1.0" over inland valleys, around 1" at the coast, and 1-2" in the Coast Range, Willapa Hills, and Cascades. Probabilities for over 0.5" of rain have settled around 85-95%, and probabilities for 1" of rain or more are 25-50% over the Central Willamette Valley into Portland metro (only 10% near Eugene), and 80-95% along the coast, Coast Range, Willapa Hills, and Cascades. /42-99 .LONG TERM...Thursday through Monday...Now that the cooler part of the week has been discussed, lets look at the warm and dry conditions of the long term forecast. As mentioned above, and upper level ridge looks to slowly build over the region for the latter part of the week and remain over the Pac NW through the weekend and into the start of next week. This synoptic pattern is resulting in moderate to high confidence in a prolonged multi-day heat wave beginning on Saturday. However, before the heat kicks in, expect rather pleasant weather on Thursday with mostly sunny skies and high temperatures in the mid to upper 70s for inland locations and , upper 60s to mid 70s for the coast and Cascades. Friday through early next week, models and their ensembles show an upper level ridge amplifying over the far northeastern Pacific, with some lingering uncertainty regarding exactly how far east the ridge axis will move. Despite the uncertainty with the location of the ridge axis, confidence is high temperatures will be heating up significantly June 13-16. For Saturday, June 13th, the NBM probabilities for daytime highs above 90 degrees F is 45-75% for the Willamette Valley. NBM probabilities for daytime highs at or above 100 degrees F on June 14th are 30-60% and 20-70% on June 15th, with the highest probabilities each day towards the northern portions (Portland/Vancouver Metro) of the Willamette Valley. Also, there is a 10-20% chance for daytime highs on the 14th and 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. Given the likely record breaking daytime highs, probabilities for a Moderate HeatRisk or higher on June 13th is 70-85%, on June 14th and 15th is 85-99%. For Major HeatRisk or higher, there is a 40-75% probability on June 14th and 25-70% on June 15th. The probability for Extreme HeatRisk across the CWA is 10% or less through June 13th through June 15th. Anyone who is sensitive to heat or those who have outdoor plans should pay attention to the forecast over the coming days and be prepared for potential extreme heat. Those planning on swimming in rivers or lakes to cool off should be mindful of cold water temperatures and swift currents, which can become life threatening. Typically with this upper level pattern, a thermally induced surface trough also looks to establish itself somewhere west of the Cascade Crest, which could result in gusty winds within the Cascades and Willamette Valley. 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. /42 && .AVIATION...Steady rain continues as a frontal system traverses the airspace through the period. Flying conditions are currently mixed, but vis/cigs are expected to be restricted to at least IFR along the coast and to MVFR at inland terminals. Chances for IFR cigs inland reach 15-35% tonight at inland terminals, while LIFR chances increase to the south along the coast from 25% at KAST to 75% at KONP. Vis restrictions to MVFR are most likely, but periods of IFR during heavier rain rates are possible at all terminals. Vis/cigs will tend to improve behind the frontal passage, after 09-15z Tue. South to southwest winds continue to build this afternoon. Peak gusts are expected to reach 25-30 kt at most terminals this evening (through 03z Tue) along the coast and this evening into tonight (through 09z Tue) inland. Periods of low-level wind shear exceeding 30 kt in the lowest 2 kft are most likely at KONP through 03z Tue. Wind speeds will tend to ease behind the frontal boundary while turning out of the southwest to west after 09-15z Tue. KPDX AND APPROACHES...Deteriorating flying conditions are expected as cigs fall below 2 kft this afternoon. Chances for IFR cigs remain at 25-35% through 03z Tue. MVFR conditions are otherwise favored to persist through 12-15z Tue while cigs slowly lift behind the front. Southerly wind gusts reaching 20-25 kt continue through 12-15z Tue, before winds ease and begin to turn out of the southwest late in the period. -36 && .MARINE...A robust frontal system continues to traverse the coastal waters this afternoon, bringing a period of gale-force gusts reaching 30-40 kt south of Cape Falcon through 7 PM this evening. Otherwise, relatively steep seas of 7-10 ft at 8-9 seconds with a dominant westerly swell are expected, while southerly wind gusts of 20-30 kt turn out of the west behind the front this evening. Conditions across the waters and including the Columbia River Bar will therefore remain hazardous to small craft through much of Tuesday. As high pressure builds offshore through the remainder of the week, west winds of 5-10 kt on Wednesday will steadily shift out of the north. Typical summertime northerlies will reach diurnal peaks of 15-25 kt each afternoon and evening from Thursday through the weekend, which may necessitate daily Small Craft Advisories, especially beyond 10 NM south of Cape Falcon. Seas will persist at 4-7 ft at 9-11 seconds with a continued westerly swell. -36 && .PQR WATCHES/WARNINGS/ADVISORIES... OR...None. WA...None.

805 FXUS66 KMFR 082347 AFDMFR Area Forecast Discussion National Weather Service Medford OR 447 PM PDT Mon Jun 8 2026 ...Aviation Discussion updated... .SYNOPSIS... Cool showery weather continues through tonight into Tuesday. Temperatures gradually trend warmer through the week. A heat wave will impact the region around the weekend into early next week. Heat risk will become high in some valleys Sunday night as overnight temperatures remain relatively warm. .DISCUSSION... There are plenty of showers on radar this afternoon with rain falling over most of the forecast area under warm air advection. Coastal locations are reporting 0.5 inches of rain with lower totals <0.1 inches around the westside valleys and even lower totals east of the Cascades. We`ll see a cold front eventually hit the coast later tonight and bring one last shot of rain mainly to coastal locations. With the relatively cooler air moving in, we`ll see the showers persist along the coast during Tuesday. Thermodynamic profiles haven`t changed with very little convective available potential energy(CAPE) around the boundary layer. This hints at just plain old showers with no electrification of the cloud. The air aloft is relatively stable and drier above 9000 feet, so these showers will be fairly shallow and likely lighter with little or no rain falling. Conditions begin to dry out by Tuesday night with some relatively cooler air already in place. There is a threat of frost over populated areas east of the Cascades early Wednesday morning as skies will begin to clear out with the trough moving east. Therefore, we put some frost in the weather wording for locations east of the Cascades Wednesday morning. Conditions trend warmer heading into Wednesday as high pressure continues to build across the region and highs move about 4 to 5 degrees warmer and meet climatological normals for this time of year. No weather concerns on Wednesday with deeper northerly flow and a short wave flying through eastern Oregon. This departing shortwave will build a healthy north east to south west pressure gradient across the state of Oregon By Thursday morning, a thermal trough begins to set up over south western Oregon and north western California. One can see this in the inverted 850mb heights and 1000-500 mb thickness values in the GFS. Temperatures will further increase as a result with some broader northeast to east flow across the region. Net result of these winds should be temperatures moving warmer. The 500 mb ridge is still situated west, although temperatures will move warmer without much change in the 500 mb heights. From Friday into the weekend, heat risk will gradually increase as temperatures continue to trend warmer. Heat peaks on Sunday as the ridge axis likely settles over our area with 592dm heights. Right now, we`re forecasting a high temperature of 105 in Medford on Sunday with a low of 65 Sunday night. The extreme forecast index(EFI) is hinting at an unusually strong heat event with max temps and min temps right around 0.8 to 0.85, which is fairly strong for early June, yet not extreme. Confidence is pretty high with the placement of this ridge based as well, so this heat is definitely on the way for southwest Oregon and northern California. Finally, it looks like this ridge flattens out around Wednesday of next week(16th-17th) based on analysis of the GEFS 500 mb heights. Therefore, this heat wave should be of the shorter variety. -Smith && .AVIATION...09/00Z TAFS...A late season system will bring continued IFR/MVFR conditions and local LIFR along the coast tonight and into Tuesday morning, then lifting to VFR around 18-20z. Inland, expect a mix of VFR and MVFR conditions with widespread terrain obscurations through early Tuesday. Showers will decrease in coverage this evening, then taper off late tonight into Tuesday morning. Areas from the Cascades west have moderate chances (40-60%) for MVFR conditions tonight into early Tuesday morning, including at Roseburg and Medford. East of the Cascades, expect areas of MVFR conditions to develop this evening. Klamath Falls has a 40% chance of MVFR ceilings in showers around 04-08z. Conditions will gradually improve Tuesday morning, becoming mainly VFR around 18z. && .MARINE...Updated 1200 AM PDT Monday, June 8, 2026...A cold front is moving through the region today, bringing gusty south winds and steep to very steep seas. The steepest seas are expected north of Cape Blanco where south gales will persist through the afternoon. Winds ease late this afternoon, but seas will remain steep for all areas into Tuesday morning, with very steep seas lingering north of Bandon through tonight. && .MFR WATCHES/WARNINGS/ADVISORIES...

217 FXUS66 KEKA 082232 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 332 PM PDT Mon Jun 8 2026 .KEY MESSAGES... - Rain will be coming to an end tonight with dry and slightly below normal temperatures Tuesday. - Temperatures are expected to warm up quickly Much warmer weather next week into the weekend. - Elevated fire weather conditions in Lake County with low afternoon relative humidity and gusty winds Wednesday through Thursday. && .SYNOPSIS...A cold front is bringing rain to the area this and this is expected to come to an end tonight. Clearing skies are temperatures below seasonal normals is expected Tuesday. Temperatures are expected warm to the upper 90s to around 100 late in the week with a moderate heat risk. && .DISCUSSION...A cold front is bringing some light to moderate rain to the area this afternoon. This will be coming to an end this evening. High pressure and northerly winds start to build back into the area on Tuesday. The low clouds in the valleys may take some time to clear out, although most areas are expected to see clear skies by midday. Highs are expected to warm into the 70s in most of the inland areas although Lake county may be close to 80. Tuesday night into Wednesday morning is expected to be a chilly night with most areas falling into the 40s. Frost is possible in the coldest spots in Trinity and eastern Humboldt counties, such as Ruth, Hayfork and Valley. The high pressure starts to build in on Wednesday with inland highs warming around 10 degrees over the previous day yielding highs in the upper 80s to low 90s. Thursday the temperatures are expected to increase by another 10 degrees or so with highs climbing into the upper 90s to around 100 in many of the inland valleys. At the coast offshore flow each night is generally expected to keep coastal areas clear with the ridge axis to the west of the coast. Breezy north winds are expected each afternoon and this will likely keep coastal temperatures in the low 60s through Thursday. Friday may start to be a transition day with some marine influence returning to the Mendocino coast. On the Humboldt and Del Norte coast Friday will be a tricky day. Winds start to weaken. This may either allow temperatures to warm up into the 70s or stratus will form and keep them around 60. Farther inland the warming continues with highs over 100 in many valleys Friday and Saturday. Moderate to locally major heat risk is expected to start on Thursday in most inland areas and continue through Saturday. One of the big factors will be the overnight lows. In the valleys the temperatures may end up dropping slightly more than currently expected and this could diminish the overnight heat risk. The details remain uncertain, especially in the coastal counties, but this is starting to look like it will be some of the hottest weather so far this summer. MKK && .AVIATION...The cold front is currently bringing some lower CIGS and VIS to the northern areas as the front moves through. Currently this is bringing variable conditions with some areas as low as LIFR. These are generally expected to remain low through the night as the front fizzles out. Tuesday northerly winds start to pick up and with the weaker inversion behind the front skies are expected to clear fairly quickly in the morning. Farther south Ukiah may see some periods of low clouds, although confidence is low on low they will get. They are also expected to clear by mid- morning on Tuesday. MKK && .MARINE...The southerly winds are expected to diminish later this evening and become northerly again overnight. Wind driven waves associated with these southerly winds have built to 3 to 6 feet in the northern waters and will diminish overnight. Early Tuesday morning a fresh northwest swell is expected to build to around 7 or 8 feet at 10 seconds. Tuesday afternoon high pressure starts to build into the waters ranging from 15 kt in the north to 25 kt in the south. So have added a small craft advisory to the southern waters to highlight this. These winds continue to build Tuesday night and Wednesday with gales expected at some point on Wednesday. So have added a gale watch to the southern waters Wednesday afternoon. At some point late Wednesday afternoon or overnight the northern waters will also see near gales or gales and a gale watch may be needed. These are expected to remain near gale or gales into Thursday and possibly into Thursday night. Thursday afternoon the gales start to push farther off the coast and this will diminish the winds in the southern waters. Friday and into the weekend the gales are expected to push farther offshore, although confidence is low on how far off the coast they will go. MKK && .FIRE WEATHER...Wetting rains are expected to come in to an end tonight in Del Norte and Humboldt counties. Dry conditions will then return Tuesday into Wednesday with temperatures warming considerably across the interior. By Thursday, high temperatures could be exceeding 100 degrees in some interior valley locations. This is expected to drop afternoon RH into the mid to upper teens Wednesday and low to mid teens Thursday across Lake county, eastern Mendocino and Trinity counties. Wednesday night into Thursday morning Rh recoveries are only expected to be around 20 to 40 percent in eastern and southern Lake county as well as far eastern Mendocino county. Wednesday night northerly winds are expected to pick up over the higher terrain of southern and eastern Lake county as well up into the Yolla Bolla mountains of NE Mendocino and SE Trinity counties. Sustained winds of 15 to 30 mph with gusts to 40 mph in some areas. The strongest winds are expected to begin very early Thursday morning and start to taper off by mid to late morning. In general this looks on the low end of the red flag criteria and there is still some uncertainty on the fuel moisture so will continue to hold off on the fire weather watch. && .EKA WATCHES/WARNINGS/ADVISORIES...

Updated at 320 PM PDT Mon Jun 8 2026 - Chance for coastal drizzle this evening into early Tuesday - Warmer and dry weather expected Wednesday - Saturday - Moderate risk of heat-related illnesses for interior locations on Wednesday and Thursday - Elevated fire weather concerns for the interior North Bay and the East Bay and Santa Clara Hills late Wednesday and Thursday && .UPDATE... Issued at 824 PM PDT Mon Jun 8 2026 The band of showers that currently extends from the Santa Cruz Mountains over to the East Bay has been overperforming so far this evening, with public reports of drizzle across the Bay Area, centered mainly on favored locations in the foothills. As a result, have added a chance for drizzle along the coastal and higher elevation locations across the Bay Area into Santa Cruz County through the night, but note that accumulations are still very light with rain totals generally a few hundredths of an inch outside the move favored locations. DialH && .SHORT TERM... Issued at 320 PM PDT Mon Jun 8 2026 (This evening through Tuesday) A disturbance will continue to track through the PacNW through tomorrow morning. So far, this has spread high clouds across the region with radar showing light returns over the North Bay. Looking at sounding data, profiles have moistened some, but favor a drier air mass. As the system progresses and a front approaches, we could see this interact with the marine layer later this evening and into Tuesday morning. This would result in coastal drizzle and perhaps even some light rain/coastal drizzle for the northwestern portion of Sonoma County. The front is expected to pass across the region Tuesday morning, with drier air working in behind it. Skies will begin will clear behind the front, which will kick off the warming trend for the week. Highs for Tuesday will be in the mid 70s to mid 80s for interior valley locations and for the interior mountains. Along the coast, temperatures will range from the upper 50s to low 70s. && .LONG TERM... Issued at 320 PM PDT Mon Jun 8 2026 (Tuesday night through next Sunday) The upper level pattern begins to change on Friday as high pressure builds over the Eastern Pacific, while troughing sets up over the west. This will lead to a stretch of warmer and drier weather through the rest of the forecast period. Some uncertainty remains in a few areas, such as where does the upper low go? The latest guidance continues to favor a inside slider type upper level trough, leading to offshore flow for our neck of the woods Wednesday through Thursday morning. The strongest winds look to occur over the interior North Bay region and along the East Bay and the Santa Clara Hills, where gusts up to 35-55mph are expected over favored ridges, gaps, and passes. On Thursday, ridging builds in ever so slightly leading to the warmest day of the week. Widespread moderate HeatRisk is expected, with temperatures rising in to the 90s for many interior valleys, with some areas even cracking 100. Along the coast, temperatures will be warm as well, ranging from the mid 60s along the immediate coast to to mid 80s inland. Warmer weather lasts into the weekend, as the ridge holds over the EPac; however, temperatures will falter a few degrees each day. There is a sign we could see the marine layer start to return Saturday or Sunday, but confidence is low on when that occurs. If there is no major synoptic change, temperatures could also trend warmer for Friday and Saturday. && .AVIATION...

Issued at 545 PM PDT Mon Jun 8 2026 Hot temperatures, gusty north winds, and low humidities across the North Bay interior mountains will raise the fire weather threats late on Wednesday into Thursday, with a particular emphasis on the interior mountains of Napa County. Although the strongest winds will remain within the Sacramento Valley, gusts of 25 to 35 mph are expected to spread into Napa County, with stronger gusts of 40-50 mph possible along the Vaca Mountains along the 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. It`s a little too early to put out fire weather products at this stage, but this will be re-evaluated today and Tuesday as the dry conditions approach. 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. && .MTR WATCHES/WARNINGS/ADVISORIES...

659 FXUS66 KOTX 090040 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 540 PM PDT Mon Jun 8 2026 .KEY MESSAGES... - Increasing rain this evening and tonight. 10-30% chance of thunderstorms Tuesday afternoon. - Drier and warmer midweek through weekend with potential Heat Risk. && .SYNOPSIS... A system brings rain into the region Monday evening into Tuesday morning. Tuesday will be breezy with showers and a threat for isolated thunderstorms. The rest of the week will be mostly dry, with warming temperatures. Widespread 80s to low 90s are forecast by the weekend. && .DISCUSSION... Today and tomorrow: Rain will begin to increase this evening as a plume of of moisture ahead of a cold front swings through the region. The trough axis is currently right off the WA/OR coast and the radar is filling in with light rain downstream. Seeing some radar returns as low as 10000 ft AGL east of the Cascades already early this afternoon. It will take a couple hours for the boundary layer to moisten from the top down. This will bring some highly beneficial rains to the entire region through tomorrow. The well defined surface low and cold front off the coast will lose its definition as it moves inland tonight, but high pressure nosing in behind this system and a low meandering through central Canada will increase pressure gradients for Tuesday. This will lead to breezy west winds across the Inland Northwest with sustained speeds around 15-30 mph and gusts around 30-50 mph. Considered wind advisories for the Waterville Plateau and the foothills of the Blue Mountains, but was not confident enough for a period of 45+ mph gusts lasting more than brief spurts. As the stable band of rain departs early tomorrow morning, attention will turn to shower and thunderstorm development as the 500 mb cold pool moves overhead. It is not particularly impressive around -20C so forecast instability is only around 100- 300 J/kg east of US-97. Cells will be capable of producing 30-50 mph outflows, pea size hail, isolated lightning strikes, and brief heavy rain. From 5 PM this evening to 5 PM tomorrow, there is a 60-near 100% chance of a quarter inch of rain for most locations outside of the lower Columbia Basin. In the lower Basin, those chances decrease to 30-50% chance. Wednesday through Monday: Wednesday will be a transition day towards warmer weather as troughing departs into Montana and ridging starts to strengthen off the Pacific coast. Showers limited to the mountains will taper off through the afternoon as height rises nose into the Inland Northwest. Temperatures will steadily climb through the rest of the week and into early next week as the upper level ridge strengthens off the coast. Temperatures will trend from the 60s and 70s Wednesday to the mid 80s to mid 90s by next Monday. The risk for heat related illness will steadily climb through the weekend and into early next week. /DB && .AVIATION... 00Z TAFs: Showers are bringing precip to many TAF sites and expected to to continue through the overnight. Ceilings will trend towards MVFR this evening into tonight as rain decreases T/Td spreads. Gusty Southwest winds will start mid morning on Tuesday. Isolated thunderstorm potential increases enough to include prob30 groups for 21-00Z. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: Moderate confidence in MVFR conditions developing between 03-08Z tonight. There is a low confidence risk (10-15%) for IFR conditions between 06-12Z at KEAT/KMWH/KGEG/KSFF/KCOE. Moderate confidence on gusty winds.

537 FXUS66 KPDT 082200 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 300 PM PDT Mon Jun 8 2026 .KEY MESSAGES... - Widespread rain shower chances and isolated thunderstorms across the forecast area Today into Tuesday - Breezy lower elevations winds develop tonight through Wednesday - Drying and warming trend late week through the weekend && .DISCUSSION... Today through Wednesday: Satellite imagery this afternoon shows a shortwave trough with an attendant surface low just offshore the PacNW, with cloudy conditions across much of the region. Area radar shows the western half of WA/OR covered in showers, with shower activity extending to the east slopes of the Cascades, eastern Columbia River Gorge, and central OR. A shortwave trough and surface low will continue to swing across the PacNW today through tonight. A rain shield will spread north and east from the Cascade crest through the remainder of this afternoon and evening, with isolated to scattered showers developing overnight. CAMs continue to indicate weak surface based instability developing across the eastern OR mountains this afternoon will also result in low chances (5-15%) of isolated thunderstorms. In the Columbia Basin, breezy winds will develop ahead of the precipitation late this afternoon, with wind gusts generally remaining less than 35 mph. Tuesday, shower activity will retreat mostly to the mountain areas and Blue mountain foothills as northwest flow aloft develops behind the trough axis exit. Weak instability will develop across the WA Cascade crest, far northeast OR, and southeast WA late in the morning and afternoon Tuesday, resulting in a slight chance (15-20%) of isolated thunderstorms. However, thunderstorm activity is expected to diminish late in the afternoon as the trough lifts into MT. Otherwise, widespread breezy southwest to west winds (15-25 mph with gusts up to 40 mph) will develop tonight through tomorrow as a cold front boundary passage tightens pressure gradients across the forecast area. In the lower elevations, the strongest winds (sustained winds 25-35 mph with gusts up to 50 mph) are expected to develop across portions of north central OR, the eastern Columbia River Gorge, Simcoe Highlands, OR Columbia Basin, OR Blue Mtn foothills, and 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 afternoon as 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 Sunday: Late in the work week through the weekend, there is great agreement amongst ensemble guidance in warmer and drier conditions developing as upper level ridging continues to build offshore the PacNW. That said, uncertainty does grow in the amplitude and position of the ridge offshore. While ensemble cluster solutions all keep the region dry through this period, about half of the members keep the upper ridge further offshore with a northerly flow into the intermountain PacNW. These solutions also favor a shortwave trough to clip the region, which would increase winds in the lower elevations and bring elevated fire weather concerns. The other half of solutions keep the ridge axis much closer with northwest flow over the region. This solution would keep the trend of light winds, but would favor increased warming across the forecast area over the weekend. Speaking of temperatures, the NBM shows a 40-60% chance of areas of the Columbia Basin/Gorge and Yakima valley reaching 90 degrees Saturday, with a widespread 40-75% chance of 90 degrees across most lower elevation locations Sunday. Lawhorn/82 && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/... Current radar shows widespread light showers across the region, with heavier showers/isolated thunderstorms near the Cascade Crest. Current guidance doesn`t support thunderstorms at TAF sites for this period, but a small (0 to 10 percent) chance proceeds through Tuesday that a storm impacts the TAF sites. Light to moderate rain showers will continue through the evening hours, with most areas chances of rain dropping to PROB30`s by the early morning hours. Winds for the most part will be breezy to windy with sites gusting up to 35 to 45 mph through the TAF period. Although VFR conditions are currently forecasted to prevail, small confidence (5 to 15 percent chance) remains that the more moderate/heavier showers could produce less than 3000 feet cloud decks and less than six mile visibility. && .Preliminary Point Temps/PoPs...

Current radar imagery shows a line of showers progressing across the northern portion of the central valley of California. Light showers are expected to fall over Lassen county of NE CA and in far northern Washoe county along the OR border. As day turns to night, shower chances across the Tahoe Basin increase, though remain less than 35%. Last night`s 12Z sounding out of Reno shows low level dry air, which will inhibit significant rainfall out of the showers today. QPF values top out at a couple hundredths at best; virga will likely be the precipitation type for today. Along with the light rain, we are expecting gusty winds across the area. As such, Lake Wind Advisories have been hoisted for many lakes, including Donner Lake, Topaz Lake, and Eagle Lake, among others. Please see the product at www.weather.gov/reno for more details. Gusts up to 40 mph are expected areawide, with wind prones gusting upwards of 45 mph and ridges upwards of 50 mph. These enhanced winds will bring a couple hours of elevated fire weather conditions for the Basin and Range where lower humidity values reside. Additionally, blowing dust downwind of desert playas and sinks may reduce visibilities along I-80 and US-50 east of Fernley and Fallon, respectively. Showers are expected to continue through the overnight hours into early Tuesday. At that point, a stray shower will be possible over Pershing and Churchill counties. As mentioned previously, chances for accumulating rainfall remain little to none. Wednesday and beyond, we warm up and dry out with earnest. Afternoon highs will reach the low 90s for valleys and upper 80s for Sierra communities, introducing areas of Moderate HeatRisk by Friday at the latest. Have outdoor plans this weekend? Make sure to stay hydrated and plan for activities during the cooler times of the day (before 10am and after 6pm). -Giralte && .AVIATION... VFR conditions for all terminals today.

With increasing confidence in critical fire weather conditions, we`ve upgraded the current Fire Weather Watch to a Red Flag Warning. We did trim off the southern end (Delta to Sac Metro) as it looks like limited duration of red flag level winds. In tandem with critical fire weather conditions, temperatures will begin to heat up as strong upper level riding builds along the West Coast. By Thursday, widespread triple digits are expected in the Valley with much above normal temperatures across higher elevations.

KEY MESSAGES: - Cool, breezy and wet conditions Tuesday through Wednesday - Another frost possible Thursday morning, especially along and south of the Interstate 90 corridor An incoming weather system from the Pacific Northwest will bring increasing clouds through this afternoon. By this evening, rain falling from these clouds may initially evaporate before reaching the surface, a process that can produce sudden, gusty winds of 30 to 40 mph. Rain will eventually reach the ground and become widespread overnight into Tuesday morning, with periods of showers and scattered thunderstorms continuing through Wednesday. The heaviest precipitation is forecast across north-central Idaho and along the Continental Divide in northwest Montana, where a half- inch or more of rain is highly likely (80 to 90 percent chance). The broader western Montana valleys will experience lighter rainfall amounts due to the rain-shadowing effect of the surrounding mountains, though localized areas could see heavier amounts under stronger showers or thunderstorms. In addition to the rain, breezy winds of 25 to 35 mph and noticeably cooler temperatures will create raw, cold conditions in the higher elevations. Backcountry recreationists should be prepared for winter-like weather, as snow levels are expected to drop to roughly 6,000 to 6,500 feet by Wednesday morning, bringing the potential for 1 to 2 inches of snow accumulation. In addition, area lakes will see choppy conditions. Forecast models indicate a drier trend for Thursday. However, clearing skies will bring the potential for frosty conditions Thursday morning, especially for locations along and south of the Interstate 90 corridor. Moving into Friday and the upcoming weekend, unsettled weather is expected to linger across the Northern Rockies. While the exact timing and intensity of individual weather disturbances remain uncertain, a weak cold front dropping from the north will keep temperatures near seasonal averages. Periodic chances for showers will also persist, primarily across western Montana, with relatively drier conditions expected across north-central Idaho. && .AVIATION...Clouds will be increasing from west to east today. A southerly gradient has developed across the region and southerly gusts 15 to 25 kts will be possible at KGPI, KHRF, and KBTM. After 09/0900z light precipitation will develop at area terminals.

Issued 229 PM MDT MON JUN 8 2026 A cold front is advancing eastward across Oregon, preceded by extensive mid-level cloudiness. Ahead of the front, a very dry air mass is in place, with humidity values near 10 percent through much of the Snake Plain, amidst winds gusting to 20-30 mph. Scattered to widespread showers will develop through this evening first across central Oregon, reaching the Treasure Valley after around 9 PM MDT. Although coverage will be high, rainfall amounts and intensity will be limited by how dry the sub-cloud layer is. In fact, the 18Z BOI precipitable water reading of 0.43" is close to the 25th percentile for the date.

(This afternoon through next Monday) WEATHER PATTERN OVERVIEW: Mid and high clouds continue to march across northern and central Nevada this afternoon. The reason for this is due to low pressure pushing across the Pacific Northwest later this afternoon and tonight. Winds are breezy to locally windy this afternoon and it will continue into the overnight. Light rain showers will develop later this evening through tomorrow. Forecast amounts appear scant with the highest probabilities expected across northern Elko county. The percent chance for a tenth of an inch or greater is sixty-five percent in Owyhee and fifty-seven percent at Jackpot. For locales along the Humboldt River valley in Elko county, expect probabilities of eighteen, twenty, and seventeen percent across Elko, Wells, and West Wendover, respectively. Overnight low temperatures will generally be in the 40s. For Tuesday, the base of the upper trough will be passing across northern Nevada. Another round of light showers are expected across the east and north during the afternoon. Lifted indices are forecast to be slightly negative across the Jarbidge wilderness and will continue the threat for isolated thunderstorms in northern Elko county. Winds will become breezy to locally windy during the afternoon, mainly out of the west. Winds will be 10 to 20 mph with gusts to 35 mph. High temperatures will be in the 70s with some low 80s in central Nevada. Look for the winds diminishing during the overnight with lows in the 30s and 40s. From Wednesday through the weekend, upper level ridging will remain off the west coast of the United States. This will bring typical breezy afternoon winds with highs during the mid-week period ranging in the 70s and 80s. Look for warming each afternoon with highs on Friday in the 80s and 90s. Overnight lows will be in the 40s and 50s. At this time, no precipitation is forecast. FORECAST CONFIDENCE & DEVIATIONS: Confidence remains high in a weak weather system moving across northern Nevada. Confidence is moderate to high with respect to northwest flow keeping things dry across the area after Tuesday with gradually warming temperatures. Minor modifications done with the NBM PoP, weather, wind, and wind gusts grids in the short term to better depict elevated/critical fire conditions across northern and central Nevada. && .AVIATION... Expect VFR conditions through the upcoming twenty-four hour period. Winds will remain gusty during the afternoon and evening hours with gusts to 30KT. Localized BLDU can hamper VSBY but not expected to be widespread. -SHRA will develop mainly north of US Highway 50 later this evening and tonight. Strong winds to 30KT will redevelop 18Z Tuesday. && .FIRE WEATHER... Critical fire conditions continues today across the northeastern and east-central zones as a red flag warning remains in effect until 11PM PDT tonight. Minimum relative humidity values will be lowest across east central Nevada as readings remain in the single digit to the low teens and will combine with winds gusting to 35 mph. Light, on and off, shower activity is expected to develop later this evening and tonight with precipitation amounts varying between a trace to 0.20 inches across northern Nevada with the highest amounts expected in the mountainous locales. Not much in the way of precipitation is expected in the valleys. By tomorrow, a weak cold front is expected to progress to the south and east across the forecast area. The best chance for an isolated dry thunderstorm or two will be Tuesday afternoon, focused in and near fire weather zones 469 and 470. Though precipitable water and instability remain marginal, cumulus buildups will be the most likely scenario with the majority of thunderstorm activity residing to the east in Utah. Look for elevated fire weather conditions tomorrow afternoon as west-northwesterly winds redevelop with gusts to 30 mph. Minimum relative humidity looks to remain around 15% or higher Tuesday afternoon across most of the forecast area though readings around 15% or lower will likely be present across the southern half of fire weather zones 425 and 427 as well as zone 426. Quieter and less windy weather is expected Wednesday over most of the area, though some wind gusts to 25 mph are possible across the northern third of fire zone 470, leading to another day of elevated fire weather conditions across northeast Nevada. && .LKN Watches/Warnings/Advisories...
