966 FXUS66 KSEW 070326 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 826 PM PDT Sat Jun 6 2026 .SYNOPSIS...An upper level trough over Western Washington today will shift eastward tonight. A weak upper ridge will produce a brief drying trend on Sunday before a series of systems produce cool and unsettled conditions for the first half of the coming week. A pattern shift toward dry and considerably warmer conditions is expected late next week as strong high pressure aloft builds into the region. && .SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...Showers and thunderstorm threat winding down this evening as an upper low departs the region. Current trends look good and match the forecast. 33 Previous forecast...Daytime heating coupled with an upper trough axis over Western Washington will produce scattered showers, isolated thunderstorms and unseasonably cool temperatures into this evening. The higher terrain of the Cascades and Olympics above 4500 feet will see some light snowfall, but it is not expected to produce any travel impacts across the passes. The trough will shift eastward tonight and a weak shortwave ridge will slide onshore on Sunday allowing the area to briefly dry out though temperatures will remain below normal. The next in a series of troughs will spread additional clouds and showers into the region Sunday night into Monday. It`s eastward progression will, however, be hindered as a weak surface low developing off the Oregon coast splits the system apart and takes the focus of the bulk of the precipitation into Oregon. && .LONG TERM /TUESDAY THROUGH SATURDAY/...The cool and unsettled pattern continues into the middle of the coming week as another upper trough digging southward along the British Columbia coast keeps showers and cool temperatures in the forecast. The narrative takes a decided turn from that point forward. Ensembles are virtually unanimous that we`ll see a substantive change in the synoptic pattern heading into late next week and the days that follow. A building upper ridge will produce a warming trend that will result in temperatures climbing back to just above normal levels swiftly on Thursday. The climb upward continues as we round out the week and likely beyond. High temperatures by the beginning of next weekend could run 10 to 15 degrees above seasonal averages as anomalously strong upper ridging takes up residence just to our west. Longer term guidance strongly suggests that the upward trend in temperatures will persist beyond the 7 day period. Probabilistic HeatRisk suggests a 90-100% chance of Minor HeatRisk across much of the lowlands by Friday and Saturday and a 40-70% probability of Moderate HeatRisk on Saturday for the interior lowlands of south Puget Sound and the Southwest Interior. Though it`s early yet, current probabilistic data has a considerable portion of the CWA likely reaching Moderate HeatRisk as we enter the June 14th/15th period with potential daytime temperatures in the mid 80s to mid 90s for interior areas from Seattle southward. Stay tuned. 27 && .AVIATION... An upper trough axis over the interior this afternoon will shift east of the Cascades tonight. Westerly flow aloft will become north to northwesterly tonight. Low level convergence will enhance some additional showers this evening across central Puget Sound, with most shower coverage diminishing tonight. MVFR ceilings can be expected around heavier showers. Remnant low level moisture and light surface winds will lead to greater coverage of MVFR ceilings across the region on Sunday morning. This will gradually lift to VFR Sunday afternoon. KSEA...VFR conditions at the terminal this evening as most of the thunderstorm activity has diminished near the terminal. More predominant MVFR ceilings are expected Sunday AM as remnant low level moisture remains in the area. These will lift to VFR Sunday afternoon. Surface winds south to southwesterly 9 to 13 knots into the throughout the evening. 27/Mazurkiewicz && .MARINE...A weak trough over the coastal waters will shift inland tonight as weak high pressure builds just offshore. Another trough and associated frontal system will approach the outer coastal waters Sunday evening then slow and dissipate in response to a weak surface low moving toward the Oregon coast. Onshore flow will increase Tuesday and Wednesday as broad high pressure gradually expands into the coastal and offshore waters. Onshore flow weakens late next week as thermally induced low pressure begins to expand northward across Western Oregon. Coastal seas are expected to remain below 10 feet through the period. 27 && .FIRE WEATHER...As upper level ridging builds into the area starting Thursday, conditions, including fuels, will need to be monitored as temperatures are expected to climb to above normal values entering into the week 2 time period. && .SEW WATCHES/WARNINGS/ADVISORIES... WA...None. PZ...Small Craft Advisory until 5 AM PDT Sunday for Central U.S. Waters Strait Of Juan De Fuca-East Entrance U.S. Waters Strait Of Juan De Fuca. && $$

619 FXUS66 KPQR 070539 AFDPQR Area Forecast Discussion National Weather Service Portland OR 1039 PM PDT Sat Jun 6 2026 Updated aviation discussion. && .SYNOPSIS...Numerous showers and isolated thunderstorms Saturday afternoon will quickly dissipate from west to east Saturday evening. Weak high pressure will bring mainly dry conditions Saturday night through at least Sunday afternoon. Scattered light showers return late Sunday evening/night before widespread steady rain arrives on Monday (85-95% chance). Steady rain will then transition to off-and-on showers Monday evening and continue through Wednesday, maintaining cooler than average temperatures. Trending much warmer and drier June 11-15 with increasing heat concerns next weekend, especially for inland valleys. && .DISCUSSION...Saturday afternoon through Friday night...Radar, satellite, and surface weather observations from Saturday afternoon showed numerous heavy showers and isolated thunderstorms over southwest WA and northwest OR. The strongest showers and storms are producing brief heavy downpours, small hail up to the size of peas, and gusty outflow winds up to around 30-35 mph. Cloud to ground lightning will also pose a safety hazard for any thunderstorm that develops. Areas that have observed repeated heavier showers or storms have picked up another from 0.2-0.9 inches of rain over the past 6-12 hours. Despite the heavy rain rates with the strongest cells, these showers and storms are moving too fast to warrant a threat of flooding as heavier bursts of rain are typically only lasting anywhere from 5-15 minutes. However, ponding of water on roads and reduced visibilities during heavier showers will be hazardous to motorists. The latest suite of CAM guidance remains in agreement for an abrupt end to the ongoing convection after 6 PM west of the Cascade foothills and after 10 PM for the Cascades and Cascade foothills. This timing seems reasonable given high pressure will be building into the area this evening while peak daytime heating wanes. Weak high pressure will then remain in place tonight through at least Sunday afternoon, bringing a brief break from precipitation. However, cloud cover will be on the increase ahead of the next weather system, resulting in the continuation of below average high temperatures in the 60s. Model ensemble guidance has come into better agreement on the arrival time of rain with the aforementioned weather system. It now appears a steady stratiform rain will arrive Monday morning into the early afternoon (85-95% chance) before transitioning to off-and-on post-frontal showers Monday evening. We will then remain in a cool and showery onshore flow regime through Wednesday. There is also a 10-20% chance of short-lived thunderstorms Tuesday afternoon, however these would be sub-severe and isolated due to limited instability. The latest NBM 48-hr probabilities for rain amounts over 0.50" now peaks between 5 AM PDT Monday and 5 AM PDT Wednesday, showing anywhere from a 60-80% chance for most locations in southwest WA and northwest OR, except an 80-95% chance in the Cascades, Cascade foothills, and Coast Range. Conditions should dry out with temperatures trending towards seasonal normals on Thursday as high pressure builds into the area. Our focus then shifts to a significant warming and drying trend late next week through next weekend. Cluster analysis for June 11-15 for 500 mb heights generally suggest upper level ridging will gradually develop over the region. This will bring a prolonged stretch of dry weather, with temperatures likely warming each day. However, there is still considerable uncertainty in regards to exactly how warm temperatures will get, which could wind up anywhere in the 80s, 90s, or even lower 100s for inland valleys. That said, confidence has increased for high temperatures of at least 90 degrees or warmer by June 13-15. By June 15, probabilities for highs above 90 degrees peak near 55-75% for inland valleys per the latest NBM guidance, and less than 10% at the coast. With the increase in temperatures, there is a 25-45% chance for a moderate HeatRisk or higher over inland valleys on June 12, a 50-75% chance on June 13, a 65-85% chance on June 14, and a 70-90% chance on June 15. There is a 5-20% chance for a major HeatRisk or higher on June 13, a 15-35% chance on June 14, and a 20-40% chance on June 15. Those who plan on swimming in lakes or rivers to cool down should be mindful of the dangers that come with cold water temperatures and/or swift currents. Anyone who is sensitive to heat and/or has outdoor plans June 12-15 should pay attention to the forecast over the coming days. -23 && .AVIATION...Predominately VFR conditions through Sunday evening, although a wet ground surface along with clearing skies and light winds will result in a 25-45% chance of MVFR clouds across the interior lowlands or fog development in sheltered locales at some point between 10-16z Sun. Any lowered flight conditions should improve to VFR by 18-21z Sun. West winds decreasing less than 6 kts with most locations becoming southerly or variable overnight as high pressure builds over the region, remaining so through Sunday. KPDX AND APPROACHES...VFR conditions most likely to prevail through the period, though there`s a 25-35% chance of MVFR ceilings developing sometime between 10-18z Sun due to the wet ground, clearing skies, and light winds. Any lowered flight conditions should improve to VFR by 18-21z Sun. Westerly winds less than 5 kts becoming variable overnight. -03 && .MARINE...An active weather pattern continues through midweek with repeated frontal systems bringing periods of rain and increased winds. Isolated rain showers this afternoon will rapidly decrease in coverage in the hours before sunset while west-northwest winds of 10-15 kt ease to around 5 kt and turn out of the south tonight. A brief dry break from Sunday into Monday as a shortwave ridge passes overhead will see southerly winds build to 15-20 kt with gusts up to 25 kt, peaking early Monday morning. Small Craft Advisories may be needed if confidence increases in the duration of wind gusts greater than 21 kt. Seas of 4-8 ft at 8-9 seconds continues with a dominant westerly swell. This next, more robust frontal system will arrive Monday night into Tuesday with additional rain and winds again turning west-northwesterly behind the boundary. Beyond midweek, there is high confidence that high pressure will build offshore, turning winds northerly over the coastal waters. Diurnal winds will peak in the afternoon and evening, reaching 15-25 kt with wind gusts near 30 kt. Seas of 6-8 ft at 10 seconds with a dominant westerly swell look to continue. -36 && .PQR WATCHES/WARNINGS/ADVISORIES... OR...None. WA...None.

037 FXUS66 KMFR 070534 AFDMFR Area Forecast Discussion National Weather Service Medford OR 1034 PM PDT Sat Jun 6 2026 ...Aviation Discussion updated... .DISCUSSION... Showers are ongoing west of the Cascades as some surface stations are reporting 0.01 inches of rain in the last hour around Roseburg. Clouds have also been sticking around due to sufficient moisture and surface heating mainly west of the Cascades. As for tonight, colder temperatures are anticipated east of the Cascades with frost covering many locations with sub freezing temperatures in much of Klamath County and northern/western Lake County near Chiloquin, Sprague River, Bly, Dairy, Chemult, Crescent and Silver Lake. Klamath Falls and Lakeview have a 60% chance of seeing temperatures < 32F tonight. Temperatures in the lower to mid 30s are expected across eastern Siskiyou and Modoc counties. Temperatures should be warmer west of the Cascades due to sporadic cloud cover and the lower elevations. Even so, overnight lows will be about 5 degrees lower than normal for early June. The trough axis will eventually swing through Sunday morning with a really weak ridge briefly setting up. Temperatures will move slightly higher compared to this afternoon, although end up right around normal for early June. A warm front will then approach the coast by Sunday night with some rain starting to fall along coastal areas. Meanwhile, ensemble members are starting to converge on that higher rain solution we talked about yesterday. The vast majority of 12Z ENS members show a surface low starting to spin up off the Oregon coast. Most of them push it a bit farther to our north near Astoria and Portland, yet a few bring the low farther south, which would lead to more rain than what is currently in the forecast. Overall, we`re looking at a solid 0.25 inches of rain for most locations west of the Cascades with lower totals east of the Cascades and in northern California. Medford is of course a dry spot, yet we`ll likely see some rain here too as PoPs are >90%. A wetting rain indeed for early June. Minimal impacts are anticipated with this rain. Once this low moves through, some slightly cooler air will move in and keep the showers going for most of Tuesday. The rain will be notably lighter and the chances of thunderstorms are <5%. Not much instability appears to make it to -10C based on the forecast soundings, so basically no electrification of the cloud. Showers should also be very shallow and light based on small amounts of convective available potential energy(CAPE) in those forecast soundings. The chances for showers decrease to <10% on Wednesday as high pressure starts to build with the departing long wave trough. We`ll see a thermal trough starting to build along the Oregon coastline Wednesday night with some 10 to 15 knot easterly winds off the Cascades and well defined inverted 850 mb heights. Main impacts for us will be warming temperatures and drying conditions towards the end of the week. It looks like the odds of 100 degrees have decreased on the other hand. We now have a 25% chance to break into the 100`s on Saturday as a thermal trough remains over our forecast area. && .AVIATION...07/06Z TAFS...VFR conditions should prevail overnight except for local mountain obscurations along the Siskiyous and Southern Oregon Cascades. Areas of MVFR ceilings are expected to develop in the Umpqua basin late tonight and early Sunday morning, including at Roseburg. Local IFR/MVFR is also possible (15%/25% chance) at North Bend but confidence is low so have kept this out of the TAF for now and will continue to monitor.. Then, late Sunday morning through Sunday evening expect VFR areawide. && .MARINE...Updated 1200 PM PDT Saturday, June 6, 2026...Gusty north to northwest winds will persist today, strongest south of Gold Beach. Seas will generally be northwest swell dominated today. The exception will be south of Pistol River where borderline advisory level winds could result in an area of steep seas beyond 1 to 2 nm from shore through tonight. As such, have made some adjustments to the Small Craft Advisory...considering seas will be swell dominated north of Gold Beach, the Small Craft Advisory for the northern outer waters was canceled while the headline was expanded closer to shore south of Pistol River. Wind ease overall on Sunday with sub-advisory conditions expected through the evening. Winds turn southerly late Sunday afternoon ahead of another cold front expected Sunday night into Monday. Gusty south winds are expected with this front, with high confidence in advisory level winds for all areas Monday morning. North of Cape Blanco, high end advisory level winds (gales?) are possible late Monday morning as a secondary surface low pressure moves onshore somewhere between Newport and Astoria. Steep seas are very likely, with very steep seas possible north Cape Blanco if winds are stronger. Improved conditions are expected for Tuesday and Wednesday. Confidence is increasing in the return of a thermal trough pattern for the latter half of next week that likely persists into the following weekend. Expect the return of gusty north winds with steep to very steep seas from Thursday onward. && .MFR WATCHES/WARNINGS/ADVISORIES... OR...Frost Advisory from 2 AM to 9 AM PDT Sunday for ORZ029>031.

938 FXUS66 KEKA 070711 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 1211 AM PDT Sun Jun 7 2026 .SYNOPSIS...Dry weather continues today with breezy afternoon winds. Low relative humidities in the interior will bring an elevated fire weather threat. Rain is likely for the North Coast Monday. Much warmer interior temperatures are likely late next week. && .KEY MESSAGES... - Near normal temperatures, dry weather, and breezy afternoon winds continue today. - Elevated fire weather conditions in the interior with low afternoon relative humidity. - Rain likely Monday for the North Coast, with the highest amounts north of Cape Mendocino. - Much warmer weather likely likely next week into the weekend. && .DISCUSSION...A trough moving through the Pacific Northwest Sunday will bring a few high clouds and bring slightly lighter winds than the previous days. This will bring slightly warmer high temperatures to the interior areas. Winds could still be breezy with afternoon gusts up to 20 mph. Wet weather is expected to return to portions of the area on Monday. Models are in good agreement for generally light to locally moderate rain for Humboldt and Del Norte Counties starting late Monday morning and through the day. Total rain amounts in Del Norte range from just under 1" to localized 1.5" or more in the mountains. Precipitation drops off significantly farther south, with only around 0.10" to 0.50" in Humboldt and coastal Mendocino, and only a few hundredths in Trinity and interior Mendocino. Models have generally been trending wetter, and westerly flow could support higher rain amounts in Humboldt and Del Norte. Some high-res models are showing this possibility with the REFS showing fairly high chances (70%) for over an inch of rain for northern Humboldt. Lake County may only see a few sprinkles, if any. South winds may be breezy in Del Norte, especially in the higher terrain and coastal headlands where gusts could briefly reach 30 to 35 mph Monday afternoon. Interior high temperatures will also drop 5 to 10 degrees, with 60s or 70s forecast for most interior valleys. This front quickly moves out of the area Tuesday with temperatures rebounding slightly to the high 70s. Low temperatures Tuesday morning may drop into the 30s in the coldest valleys, including Hayfork and Ruth. Frost is currently not expected, but this will need to be watched. Warming temperatures are expected to start on Wednesday and will likely continue to to warm through the end of the week and into the weekend. Interior high temperatures in the 90s and possibly into the triple digits for the warmest valleys are possible by Thursday and Friday. Warm and dry weather is expected to continue into the weekend. JB && .AVIATION...(6Z TAFs)...Only a few patches of coastal stratus are being observed so far. A weak marine inversion will likely keep stratus impacts minimal overnight, still some brief MVFR to VFR ceilings are possible. Low ceilings will clear shortly after sunrise. High clouds will increase today, but conditions will remain VFR at all terminals. Breezy north winds of up to 20 kts are possible this afternoon. JB && .MARINE...Winds ease today as a front approaches the area from the north. The main exception is in the lee of Cape Mendocino where near- gale to gale force gusts are possible this afternoon. North winds continue to diminish tonight and turn southerly as the front approaches. Generally, seas are forecast to subside significantly as north winds ease, and could be as low as 4 ft Sunday night into Monday. South winds could be strong north of the Cape and briefly near or exceed gale force in the northern outer waters. A post frontal swell of around 7 ft at 10 seconds arrives Monday night into Tuesday. This could bring combined seas back to 8 to 9 ft. Strong northerly winds return Tuesday and are likely to continue through the work week. JB && .FIRE WEATHER...Breezy west-northwest winds continue today, but are expected to be slightly lighter than previous days. Gusts of 20 to 25 mph are possible over exposed ridges and in channeled terrain. Minimum relative humidity in the afternoon is expected to drop into the teens or 20s for the eastern portions of the area (Trinity, eastern Mendocino, and Lake Counties). These afternoon winds along with low RHs will bring elevated to locally critical fire weather conditions. Wetting rain is very likely for Del Norte, Humboldt, coastal Mendocino, and western Trinity. Probabilities drop off farther south and east to near zero in Lake and southern Mendocino. JB && .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS...

The forecast remains on track. DialH && .SHORT TERM... Issued at 103 PM PDT Sat Jun 6 2026 (This evening through Sunday) A deep upper level low will move into the PNW today. This will bring a cooler airmass and below normal surface temperatures to our region. Temperatures are running between 3 to 7 degrees below normal across the lower elevations and around 10 to 15 degrees below across the higher elevations. Coastal temperatures stay in the 50s to 60s while interior areas stay in the 70s to mid 80s. Seasonally cool temperatures continue into Sunday with high temperatures remaining similar to Saturday. Coastal residents and anyone driving through elevated terrain and mountain gaps/passes may notice gustier winds today. As of noon, most coastal areas have seen gusts between 20 to 35 mph while the higher elevations/mountain gaps and passes have seen gusts to around 45 mph. The SFO-WMC gradient is expected to strengthen to +10 to +13 mb this afternoon with surface winds to remain gusty throughout the day. For the most part wind gusts should stay similar to what was observed this morning but cannot rule out locally stronger gusts across areas that promote terrain wind funneling (the Altamont Pass and San Bruno Gap). Winds ease heading into Sunday as the SFO-WMC pressure gradient relaxes overnight. Breezy winds return along the coast and across mountain gaps/passes during the day on Sunday with the SFO-WMC gradient restrengthening to around +7 to +8 mb. Winds will be weaker on Sunday than on Saturday with gusts peaking between 20-25 mph along the coast and locally stronger gusts across mountain gaps/passes. && .LONG TERM... Issued at 103 PM PDT Sat Jun 6 2026 (Sunday night through next Friday) Upper level troughing and seasonally cool temperatures continue into the early work week with drizzle/light rain possible late Monday into early Tuesday. High temperatures stay in the 50s to 60s on the coast and in the 70s across the interior on Monday before a warming trend kicks off Tuesday. As upper level troughing persists, it will bring a good stream of moisture to the West Coast Monday night into early Tuesday. PWATs are particularly impressive for an early summer system with values ranging from 1" to 1.3". As the night shift noted, June is typically the start of our dry season when we typically see no rain. The current forecast shows up to a tenth of an inch across the North Bay and a few hundredths of an inch along coastal San Mateo County and the SF Bay shoreline. Looking at ensembles, models are in agreement that any precipitation will be light and generally less than a tenth of an inch. On the higher end of the forecast, ensembles suggest up to three tenths of an inch in the North Bay Mountains with around a tenth of an inch across the Bay Area. The higher end forecast seems unlikely at this current moment, with most models in support of the most likely forecast. Not currently seeing much thunderstorm potential with this system for MTR`s warning area. MUCAPE values are generally negligible with more likely potential for thunderstorms to the north and south of our service area. The most likely scenario is drizzle to light rain across the North Bay with drizzle extending into the Bay Area/along the coast. Totals will be light but, given that we are now in the dry season, any rain at all is beneficial. Tuesday acts as a transition day with temperatures warming into the mid 70s to low 80s across the interior before a more substantial warming trend kicks off mid to late week. Temperatures will be seasonally warm (60s to mid 70s) along the coast and above normal (mid 80s to mid 90s) across the interior. This is still a ways out but ensemble cluster guidance does support ridging building in mid to late week as upper level troughing moves eastward. There is some potential for gusty northerly winds across the North Bay Interior Mountains Wednesday into Thursday as upper level troughing digs into the Intermountain West. Cluster guidance is in good agreement that ridging will be centered over the Eastern Pacific/extend into the West Coast but it disagrees as to how much the trough will dig/how deep it will be over the Rockies. Any fire weather concerns from this may be semi abated (depending how much precipitation falls) by drizzle/light rain on Tuesday. && .AVIATION...

362 FXUS66 KOTX 070550 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1050 PM PDT Sat Jun 6 2026 .KEY MESSAGES... - Frost expected across the Northern Valley`s Saturday night and early Sunday. - Rain moves in Monday night with an 80% chance of at least a tenth of an inch over much of extreme eastern Washington and into the Idaho Panhandle. Precipitation turns showery on Tuesday with a 10-30% chance for thunderstorms. - Trending drier Wednesday into next weekend with high confidence for above normal temperatures by Friday. There is a 30-50% chance for temperatures in the upper 80s to low 90s by next Sunday and widespread minor to moderate HeatRisk. && .SYNOPSIS... Gusty west to southwest winds will continue through Saturday afternoon before winds relax through in the evening. Temperatures tonight will be chilly in the northern mountain valleys with overnight lows in the 30s with frost development expected. A wetter storm system with widely scattered light rain across the region late Monday into Tuesday morning. Breezy with showers Tuesday afternoon with the threat for isolated thunderstorms. The rest of the week will be drier with warmer temperatures. && .DISCUSSION... Rest of this afternoon through Sunday night: An upper level low pressure system will push across the Inland Northwest. A -27 degree Celsius cold pool at 500 mb is moving into the Cascades and into the Okanogan Highlands which is steepening the mid level lapse rates explaining the developing convection over these areas. A good amount of drier air descended down the east slopes of the Cascades into the Columbia Basin with the cold front and this will make it more difficult for much appreciable precipitaiton to fall with developing convection over the Columbia Basin this afternoon. There will be isolated showers that pop up into the evening and these showers will develop and drift over the Spokane/Coeur d`Alene areas and the Palouse as well; low levels appear to be too dry though to see enough charge separation for thunderstorms, but cannot completely rule out a one hit wonder with a probability of occurrence at around 10 percent today. The Pasayten Wilderness and mountainous areas across northeast Washington will see higher probabilities for thunderstorms at 20-30% chance through the rest of the afternoon. Good mixing with a modest southwest gradient will keep winds gusty into the early evening with gusts up to around 25-30 mph. Showers and wind gusts will wane through the late evening hours. Some breaks in the cloud cover and dew points in the low 30s across the northern mountain valleys will bring the risk of frost formation overnight. Make sure to cover any sensitive vegetation or bring them indoors to protect from frost damage. Showers will linger over the mountains of northeast Washington and the Idaho Panhandle on Sunday. Isolated thunderstorms in the afternoon is expected for the Northeast Mountains closer to the Canadian border and over North Idaho. Chances will be less than today at 20 percent probability. Overall, tomorrow will see drier conditions over north-central Washington and across the Columbia Basin. It will still be a bit breezy with western winds gusting up to around 25 mph and temperatures 2-5 degrees warmer with less in the way of cloud cover, especially in the western Columbia Basin, Okanogan Valley and valleys in the east slopes of the Cascades. Temperatures are not expected to be as cold Sunday night, but there could be some isolated pockets of frost developing for the colder pockets in the northern mountain valleys. Monday through Wednesday night: A second shortwave trough of lower pressure will swing through around Monday night into Tuesday. This disturbance will push across as an open wave off of the eastern Pacific will be accompanied by a more robust P-Wat plume that traces all the way back to the subtropical regions of the west-central Pacific. Integrated Vapor Transport (IVT) of between 250-500 kg/m*s will be directed into the state of Oregon. A fraction of this moisture content then pushes northward across the Inland Northwest with a warm frontal band Monday night quickly followed by the cold front early Tuesday. This storm system will look different that our typical June precipitation events in that the precipitation along the warm front will more likely move across as a greater areal coverage stratiform band. Milder temperatures with the warm front will push snow levels up a bit, but still could see an inch or snow of light snow at the higher peaks about 6,000 feet in the Cascades as colder air moves in the cold front. Otherwise, looking at rainfall across the rest of the region. There is an 80-90% chance for wetting rains (at least 0.10 inches) across the eastern half of the forecast area, and a 70% chance of at least a quarter of an inch of rainfall. Tuesday morning may be a bit damp outside. The Columbia Basin will also see a shot at rain with a 25-50% of seeing at least a tenth of an inch. The stratiform portion of the precipitation comes to an end Tuesday morning with the passage of the cold front. We then transition to showery precipitation in the afternoon and the morning rainfall will prime the pumps for convection in the afternoon with skinny CAPE sounding profiles. Just enough instability to get pop up thunderstorms across much of the Inland Northwest, especially east of the downslope areas of the east slopes of the Cascades. Thunderstorms will be pulse type storms featuring occasional lightning, heavy downpours, and brief small hail. Pressure gradients will tighten as well with breezy westerly winds for the afternoon. Winds will be strongest across central Washington in the lee of the Cascades from Wenatchee/Chelan into the western Columbia Basin with gusts up to 30-40 mph expected. Showers will continue into Wednesday primarily along the Cascade crest, and over the Northeast Mountains and the Idaho Panhandle. Isolated thunderstorms in the afternoon is expected mainly for the higher terrain over the Northeast Mountains into North Idaho. Temperatures for Monday through Wednesday will remain below normal with highs generally in the 60s to low 70s. Thursday through Saturday: There is good consensus from the model ensembles for a ridge of high pressure to be pumped up over the eastern Pacific Ocean. This means high confidence in the far extended portion of the forecast for temperatures warming above normal. Some uncertainty remains with where the ridge axis will set up and this will play a part in how warm we get. There is a 30% chance for moderate HeatRisk to be a factor by next weekend though with a 30-50% chance for widespread 90 degree temperatures by next Sunday into the beginning of the following week in the Columbia Basin, in the Lewiston- Clarkston Valley, at Wenatchee, and in the Okanogan Valley. /SVH && .AVIATION... 06Z TAFs: A cold upper-level low will move through the Inland Northwest Sunday with shower chances retreating to far northeast Washington and the Idaho Panhandle. The boundary layer remains dry with widespread VFR conditions expected through the period. Flat cumulus development is anticipated Sunday afternoon with cloud bases above 7k feet. Winds will become breezy in the afternoon from the west to southwest with gusts 20 to 25 knots. There will be enough instability across far northeast WA and north Idaho to support a 15-20% chance of lightning. KCOE has a 10% chance Sunday afternoon, which was too low to include in the TAF.

827 FXUS66 KPDT 070528 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 1028 PM PDT Sat Jun 6 2026 .Updated Aviation Discussion. .KEY MESSAGES... - Isolated Thunderstorms and scattered showers across the Cascade Crest with breezy conditions in the lower elevations today - Widespread rain shower chances and isolated thunderstorms across the forecast area Monday into Tuesday - Breezy lower elevations winds develop Tuesday through Wednesday && .DISCUSSION... Today through Sunday: Satellite and radar imagery this afternoon shows an upper low swinging into the PacNW with shower/isolated thunderstorm activity mostly west of the Cascade crest. A few isolated showers have made there way east into portions of the WA Columbia Basin. Otherwise, breezy Cascade gap winds have spread into the lower elevations. Breezy winds and mostly Cascade crest rain showers will continue through the evening as the upper low tracks across the PacNW. A few isolated thunderstorms will be possible along the Cascade crest and east slopes through this evening thanks to weak CAPE (100-250 J/kg), moderate mid-level lapse rates, and upslope flow. Shower activity will diminish across the Cascade crest tonight as the upper low pushes east of the forecast area with a transient ridge following close behind. However light showers will be possible through the early morning across the Eagle Caps and ridges in eastern Wallowa county. Breezy winds today will become locally breezy tomorrow as a cross-Cascade pressure gradient weakens slightly under the transient ridge. Mid to high elevation valleys will see near to below freezing temperatures develop Sunday morning. Temperatures below freezing in central Oregon and Wallowa county will be dependent on how quickly a drier airmass on the backside of the low settles into the region tonight, as well as winds becoming light and terrain induced. Monday through Wednesday: Ensemble cluster guidance starts in great agreement Monday of an upper shortwave trough amplifying over the PacNW as it rounds a closed low in the northeast Pacific. The trough will continue to swing east over the region through Tuesday and push into the northern Rockies by Wednesday morning. Offshore, ensemble guidance is in agreement in an upper level ridge developing sometime Tuesday through Wednesday, but disagreement grows in the positioning and amplitude of the ridge Tuesday night through Wednesday. Confidence is mod-high (65-80%) in widespread showers developing Monday as the trough moves inland, then shower activity retreating to the mountains Tuesday as the trough axis moves east of the Cascade crest. Isolated to widely scattered weak thunderstorms will also develop in areas underneath and just east of the trough axis Tuesday afternoon into the evening hours. By Wednesday, forecast confidence becomes low-mod(30-50%) in shower activity continuing across the Cascade crest and eastern mountains through Wednesday, owing to the ensemble uncertainty in the evolution of the offshore ridge. Otherwise, there is mod- high confidence (70-80%) in breezy winds (15-25mph with gusts up to 45mph) developing through the Cascade gaps and spreading into the lower elevations Tuesday and Wednesday. Thursday through Friday: Ensemble guidance remains in disagreement over the evolution of the synoptic pattern through the end of the work week. About 40% of ensemble cluster members favor the upper ridge extending across the PacNW, resulting in drier and warmer conditions developing during this period. Meanwhile, the remaining members favor the PacNW just on the edge of a broad upper level low centered over the Canadian Plains while an upper ridge amplifies poleward offshore. These solutions would all result in light rain showers over the WA Cascade crest and higher terrain over the northern Blues, and weaker warming trend across the forecast area. Confidence in the forecast through this period is low (20-35%). Lawhorn/82 && .AVIATION /06Z TAFS THROUGH 06Z MONDAY/...

588 FXUS65 KREV 062015 AFDREV Area Forecast Discussion National Weather Service Reno NV 115 PM PDT Sat Jun 6 2026 .KEY MESSAGES... * Gusty westerly winds and low relative humidities have prompted widespread critical fire weather concerns for today. * Temperatures cool off to near or slightly below early June seasonal averages Sunday through much of next week. * Gusty winds and shower chances return early next week, then a return to drying out and warming up for late-week. && .DISCUSSION... The dry cold frontal passage today has been kicking winds up already, strongest winds will continue through this evening. Gusts are already being observed 35-40+ mph, with ridge gusts creeping up to 55-60 mph territory. This timing will coincide with low relative humidity values, especially across the Basin and Range of western Nevada and portions of northeastern California. This combination, along with fuels that have become more receptive to spark, have prompted the Red Flag Warning for today through 11 PM tonight. See the Fire Weather section below for more details. Exercise caution today, including avoiding creating sparks with dragging trailer chains, target shooting or driving over dry vegetation. Once this frontal boundary sweeps through the region, Sunday will be marked by cool northerly winds that will nudge temperatures across western Nevada a few degrees cooler than today`s high temperatures. This downward temperature trend will continue into Monday, taking daytime highs closer to seasonal averages for the beginning of June. This reinforcement of cooler air will be supported by a secondary frontal passage, with a source region of the Gulf of Alaska. This suggests a more moist and cool airmass, which translates to the cooler temperatures and shower chances that are currently taking aim at the late Monday time frame for our area. In fact, recent modeling suggests the main time frame of concern for showers will be late Monday into early Tuesday. Some CAMs hint at lingering showers through Tuesday evening, but largely are out of the area by overnight Tuesday into Wednesday. Best chances exist along the Oregon border into the northern Sierra, where chances range 40-80%, but are concentrated to the overnight hours as mentioned. Various solutions have suggested other durations, but this trend has been depicted in the majority of 12z runs of both mid-range and CAM guidance. As for the winds associated with the early week FROPA, several context clues lean toward wind speeds similar to today`s winds across the ridges, with similar to leaning slightly lighter for valleys. The evidence to this includes a robust jet streak associated with the next front, however the angle at which it approaches is less favorable, despite wind speeds contained within. Another consideration is the lack of thermal gradient due to overall cooling from today`s first frontal passage. So, while 700 mb winds are on par for Monday to reflect today`s ridge winds, the mixing of the winds to the valley floors looks limited. This will undoubtedly evolve in future iterations of the forecast cycle, so stay tuned as we work out the details. Alrighty then, we will wish a fond farewell to showers and gusty winds by Wednesday, but we will notice light east winds developing on the backside of the front for late Wednesday into Thursday. By Friday, typical afternoon summer breezes return, along with a ridge that will advance from the Pacific that will bring back a heating and drying trend to our forecast. HRICH && .AVIATION... * Gusty winds will be 35-40 kts to area terminals today, with FL100 westerly winds at 30-35 kts. This may induce pockets of LLWS and turbulence with mountain wave behavior. Winds are expected to taper after 06z Sunday. * Showers are aiming to arrive around 06z Tuesday to KSVE, KLOL, KTRK and even KTVL. Chances range 15-20% for the above mentioned terminals through 12z Tuesday, then decrease to 5-10% as day breaks. Justin/HRICH && .FIRE WEATHER... A Red Flag Warning is valid for this afternoon and evening across western NV and portions of northeast CA. The winds will be highest over western Nevada with a 75-95% chance for gusts to 40 mph. Elsewhere in the eastern Sierra, there`s a 50-70% chance for gusts to 40 mph in valley locations with stronger winds for midslopes and ridges. Minimum RH ranges 9-13% in NV valleys and 10-18% in northeast CA for this afternoon. Longer critical wind/RH overlap supports 8-10 hours of Red Flag conditions across western NV and into eastern Lassen County. Other areas such as lower Mono County valleys, including the Chalfant Valley, will also see a couple hours of elevated fire weather conditions. -Justin/HRICH && .REV Watches/Warnings/Advisories...

An approaching system brings cooler, near normal temperatures through the weekend, with mid to upper 80s expected in the Valley, Delta, and lower foothills. Daytime humidities remain low, primarily in the teens to low 20s (though areas in the northern Sacramento Valley may dip down into single digits on Sunday). This, in combination with gusty winds will bring a few intermittent hours of elevated fire weather concerns in the northern Sacramento Valley. On Sunday, strongest winds will occur overnight into the early morning, tempering some of the risk for elevated fire weather concerns since they do not coincide with minimum daytime humidities. ...Monday and Tuesday... A secondary trough will move in behind the first early next week. The primary impacts expected from this system at this point are below normal maximum daytime temperatures (low to mid 80s for the Valley) and increased daytime relative humidities. There is still a slight chance (15 to 40%, highest near Lassen National Park) for a quarter inch of rain or more in the mountains and portions of Shasta County, but chances continue to diminish as we get closer to the early parts of next week. ...Wednesday through Friday... Northerly winds increase as the early-week trough shifts into the Great Basin. Gusty winds and low humidity will bring increased fire weather concerns across the Valley, Delta, and lower foothills, especially Thursday and Friday. Temperatures trend higher late in the week, with hints of mid 90s to potential triple digit highs in the Valley by the weekend. && .AVIATION... VFR conditions over the next 24 hours. Northwest surface wind gusts 15 to 23 kts in the northern San Joaquin Valley until 05Z Sunday and in the northern Sac Valley through 19Z Sunday.

KEY MESSAGES: - Scattered showers, isolated thunderstorms, and cooler temperatures today. - Frost potential in northwest Montana this morning, becoming more widespread on Monday morning. - Cool and wet conditions Tuesday through Wednesday Today through Monday... A cold front will continue to slowly push through the Northern Rockies this morning, bringing widespread showers primarily south of I-90. Snow levels will drop to 5,000-6,000 feet, resulting in 1 to 2 inches of light accumulation in the backcountry. Partial clearing near the Canadian border will also introduce localized early-morning frost concerns. By this afternoon, scattered rain showers will develop across the remainder of the region. Daytime temperatures will be 10-15 degrees below normal with westerly wind gusts of 20-30 mph, thus it will feel cool for June. As skies clear and drier air settles in tonight into Monday morning, widespread frost will threaten sensitive vegetation in the valleys of western Montana and the high valleys of north-central Idaho. Additional Frost Advisories will likely be required. Monday will provide a brief period of calm weather before the next system approaches. Tuesday through Wednesday... An incoming weather system on Tuesday will increase shower and thunderstorm activity across all of western Montana and north-central Idaho. Recent model guidance suggests this system will be more progressive (faster-moving) than previous runs indicated. A high probability (70% to 90%) remains for at least 0.50 inches of rain along the Continental Divide in northwest Montana and north-central Idaho, with lighter totals expected in the broader valleys of western Montana. There is a lower (10% to 20%) chance of heavier rainfall totaling 1 to 2 inches or more along the Divide. If this wetter scenario develops, localized flooding could become a concern for recently saturated areas, including the Mission Mountains and surrounding valleys. Looking further ahead, a general trough remains over the Northern Rockies Thursday into next weekend. Temperatures return to seasonable levels but the pattern leaves open daily shower chances. && .AVIATION...Frontal lift and jet dynamics will drive widespread showers this morning, primarily from I-90 southward. Expect considerable MVFR ceilings and visibilities, with frequent mountain obscurations. Freezing levels will drop to around 5,000-6,000 feet MSL, though backcountry snow accumulations will remain light. Behind the front, a cold core aloft and daytime heating will induce instability, generating scattered afternoon showers. Westerly wind gusts of 20 to 30 knots will be common this afternoon before diminishing around sunset. Showers will taper off mid-to-late evening, with skies clearing overnight. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...Frost Advisory until 11 AM MDT this morning for Kootenai/Cabinet Region.

835 FXUS65 KLKN 061930 AFDLKN Area Forecast Discussion National Weather Service Elko NV 1230 PM PDT Sat Jun 6 2026 .KEY MESSAGES... * Critical fire weather conditions this afternoon * Fair weather and cooler conditions Sunday * Elevated fire weather conditions ahead of the cold front Monday * Chance of precipitation Monday evening thru Tuesday night && .DISCUSSION... (This afternoon through next Saturday) WEATHER PATTERN OVERVIEW: Cold front associated with an upper level trough to the north is pushing through Nevada with winds strengthening throughout the day on an already dry surface which has promtpet Red Flag Warnings across the region until 11 PM today. Sustained west-southwesterly wind gusts near 35 mph with relative humidity below 10%. Winds will shift from a west/southwest to a more northerly flow as the front passes over as well as dissipating to lower speeds overnight. There is still a low chance (below 10%) for some dry thunderstorms this evening and into the early morning hours with best potential over White Pine County and Elko County, however confidence remains low and will not include in the gridded forecast at this time. High temperatures this afternoon in the upper 70s to 80s with cooler temperatures starting to enter over northern Nevada this evening. Overnight lows in the 40s to 50s with parts of northern Nevada along the state border dropping into the 30s. Tomorrow, fair weather conditions expected throughout the day as the front has passed over Nevada, with lighter winds than the day prior but still seeing gusts up to 15-20 mph. Cooler temperatures with highs in the 70s across the region, 60s north of I-80. Monday, a second upper level trough with a cold front will move across Nevada in the afternoon. Ahead of the front, winds are expected to increase again with sustained west/southwesterly winds up to 15-25 mph, and gusts as high as 25-40 mph. The strongest winds are expected in central Nevada and eastern Elko County. Elevated fire weather conditions expected as winds with dry surface with relative humidity below 10% will prompt a Fire Weather Watch for central and eastern Nevada from 11 am to 11 pm. Conditions will lessen in the evening has humidity levels increase to well above thresholds as moisture is expected to enter the state with the passing front. Chances for precipitation increase with northern Nevada (mainly along the I-80 corridor) seeing a 40-50% chance of light rain up to 0.01 with a 20% probability of seeing up to 0.05 inches of rain. South of the I-80 corrdior, Eureka has a 20% chance of light precipitation, however the rest of US-50 corridor and central Nevada see less than 10% chance which will keep the area dry. Fire weather conditions improve across the state as humidity levels rise above 15% with winds becoming lighter. High temperatures slightly higher as warmer temperatures move back in just before the cold front in the 70s to 80s. Chances of precipitation continue into Tuesday and dissipate by the afternoon as the trough weakens and moves north. By late afternoon into the evening, fair weather conditions take hold over Nevada with cooler temperatures as highs expected to be in the 70s. Rest of the week, fair weather conditions with warming temperatures back into the 80s. Winds expected to be light each day. && FORECAST CONFIDENCE & DEVIATIONS: High confidence of critical fire weather conditions this afternoon and evening. Moderate confidence of elevated fire weather conditions Monday afternoon ahead of the second cold front. Moderate confidence for periods of precipitation across northern Nevada Monday evening through Tuesday. Moderate confidence fair weather conditions return Tuesday evening through the rest of the week. No changes to the grids at this time. && .AVIATION... Look for VFR conditions across all terminals over the next 24 hour period. Strong gusty winds affecting all terminals as a cold front passes over with west/southwesterly winds up to 10-20 kts, gusts as high as 20-30 kts. Strong winds may cause BLDU conditions at terminals. Winds this evening will shift from west/southwesterly to a more northerly direction and dissipate to lighter speeds below 10 kts with the exception of KENV staying above 10-15 kts. Build up in clouds with CIG levels between FL100-150 over the eastern terminals as mid-level moisture increases with a 10% chance for dry thunderstorm activity this evening and overnight near KELY, KEKO and KENV, however confidence remains low at this time and will keep dry thunderstorms out of the TAFs. && .FIRE WEATHER... Critical fire weather conditions across all zones this afternoon and evening as strong gusty west/southwesterly winds up to 30-40 mph with min RH values below 10% as a cold front pushes over Nevada. Red Flag Warning is in effect until 11 pm this evening for all fire zones. There is a low probability (10% or less) for a dry thunderstorm or two this afternoon or evening. The best potential will be within zones 425, 469 and 470. At this time, the thunderstorms will be omited from the forecast as confidence remain low for the scenario to occur. This will increase cloud cover over the area. Winds will shift from a west/southwesterly to a more northerly direction as the front passes over. Fair weather and cooler temperatures Sunday with some light breezes. A second upper level trough will move into Nevada Monday and bring increasing chances for precipitation across the northern zones, while central zones remain dry. Ahead of the front, elevated fire weather conditions as wind increase with dry conditions of min RH below 10% throughout the day. Fire weather watch has been issued for zones 425, 426, 427, and 470 for Monday from 11 am to 11 pm. By the evening, fire weather conditions will improve as RH values increase above critical thresholds with winds dissipating once the cold front passes over. && .LKN Watches/Warnings/Advisories...
