573 FXUS66 KSEW 291550 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 850 AM PDT Mon Jun 29 2026 .SYNOPSIS... A broad upper level trough will continue to produce unsettled and cool conditions across Western Washington into midweek along with chances for mainly mountain showers. Drier conditions and a modest warming trend are expected for the upcoming holiday weekend with a weak ridge of high pressure aloft. && .SHORT TERM /TODAY THROUGH WEDNESDAY/... No significant updates to the forecast this morning. Stratus will prevail through much of the day, with clouds trying to break late this afternoon. This will keep temps moderated, currently in the mid 50s, reaching the mid to upper 60s this afternoon. 62 Western Washington remains under the influence of broad upper troughing aloft and low level onshore flow. At the risk of sounding like a broken record, the forecast into midweek will largely mimic what we saw yesterday. Night and morning low clouds will stubbornly give way to a few peeks of late day sun over the interior lowlands and temperatures will be held several degrees below seasonal averages. A series of weak disturbances moving through the trough will occasionally kick off a shower over the higher terrain or squeeze out some coastal drizzle, but otherwise mainly dry conditions will prevail. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... The long term forecast period begins with much the same trend of cool unsettled conditions. A few of the operational model runs attempt to bring a weakening frontal system into the area on Thursday, but it may well encounter a building ridge offshore and result in little if any precipitation away from the coast and Olympic Peninsula. As we move toward the upcoming holiday weekend, ensembles are continuing the trend of previous runs which have upper troughing retreating into the northern Gulf of Alaska and at least some upper ridging rebuilding into the Pacific Northwest. There`s still a decent spread in solutions with regard to the strength of the ridging, but the overall ensemble averages suggest a return to temperatures near, if not a little above, seasonal norms for early July along with dry conditions. 27 && .AVIATION... Broad upper troughing over the interior West will continue to maintain northwesterly flow aloft over Western Washington. MVFR to IFR cigs prevail across western Washington this morning, but is expected to slowly lift throughout the morning to low-end VFR by the afternoon for interior terminals. Clouds will likely try to break but ceilings are not expected to fully scatter. Ceilings will likely deteriorate back to low MVFR or localized IFR once again tonight and through much of Tuesday morning. KSEA...MVFR with occasional periods of IFR this morning. Expecting slow improvement through the morning, with low-end VFR after around 21Z. Ceilings may become broken but not expecting full scattering. Ceilings will fall back to MVFR late tonight and continue through Tuesday morning. Surface winds south to southwesterly 7 to 10 knots rising to 9 to 12 knots later this evening. 27/62 && .MARINE... A broad surface ridge centered well offshore and lower pressure across the interior will remain the dominant weather pattern into midweek. This will maintain onshore flow with gusty northwesterlies and steep seas for the coastal waters. Diurnally driven westerly pushes will occur in the Strait of Juan de Fuca as well. The offshore ridge is expected to weaken during the later half of the week as a broad surface low approaches the central British Columbia coast. This will weaken onshore flow allowing winds over the coastal waters to ease and seas subside. 27 && .FIRE WEATHER... Little in the way of fire weather concerns remain in the picture into the week ahead with upper troughing maintaining cool conditions, high RH, and periodic chances for shower activity. A trend toward more seasonable temperatures is indicated toward late week, but a significant warm and dry spell is not expected in the next 7 days. && .SEW WATCHES/WARNINGS/ADVISORIES... WA...None. PZ...Small Craft Advisory from 5 PM this afternoon to 2 AM PDT Tuesday for Central U.S. Waters Strait Of Juan De Fuca- East Entrance U.S. Waters Strait Of Juan De Fuca.

Conditions will be mainly dry aside from a few stray sprinkles, mainly over higher terrain. A gradual warming trend develops Friday into the holiday weekend with inland valleys likely warming above 80 degrees by the 4th of July (70-90% chance). && .DISCUSSION...Monday afternoon through Sunday night...Visible satellite imagery Monday afternoon shows mostly cloudy skies across NW OR and SW WA. Temperature observations at 2 PM are only in the low to mid 60s across the interior lowlands and 50s to low 60s elsewhere under the cloud cover. This is due to longwave situated over the Western US bringing cooler and moist air from the north into the PacNW. Model ensemble guidance continues to suggest this pattern will continue through Thursday, allowing cool onshore flow to persist with extensive cloud cover each day during the morning and early to mid afternoon hours. This will keep temperatures cooler than average for this time of year with high temperatures ranging from the mid 60s to lower 70s each day, coolest at the coast. The latest forecast is trending mainly dry each day aside from a few stray sprinkles from time to time, mainly over higher terrain. Conditions will begin trending warmer Friday into the upcoming holiday weekend as weak upper level ridging develops. Although there is still a large degree of total model spread for temperatures, confidence has increased highs will warm to at least 80 degrees for inland valleys by the 4th of July Saturday (70-90% chance per the latest NBM guidance). Probabilities for highs of 80 degrees or warmer are similar on July 5th as well. Chances for highs of 90 degrees or warmer are under 10% on Saturday, increasing Sunday to 10-25%. That being said, chances for highs at or above 95 degrees are only 0-5%, suggesting the warmest possible scenario would be somewhere in the lower 90s. In addition, overnight lows are expected to be in the 50s, which will offer excellent relief for those without access to air conditioning regardless of whether or not temperatures end up in the 80s or lower 90s. -23/03 && .AVIATION...Widespread cloud cover continues while coastal terminals bounce between IFR and VFR, and inland terminals bounce between MVFR and VFR. Expect prevailing VFR conditions inland and prevailing MVFR conditions along the coast by 22-23Z Mon. With a 50-80% chance of MVFR CIGs at coastal terminals through the TAF period, brief VFR CIGs may occur. Additionally, there is a 10-20% chance of IFR CIGs at KONP through the period. Between 11-20Z Tue, there is a 30-50% chance for MVFR CIGs at inland terminals. Otherwise, expect generally northwesterly winds around 5-10 kt during the afternoon, becoming light and westerly/southwesterly overnight. KPDX AND APPROACHES...Currently overcast and VFR, with CIGs around 3500-4000 ft. Expect CIGs to increase above 4000 ft by 22-23Z Mon. There is a 30-40% chance for MVFR CIGs between 11-20Z Tue. Northwest winds around 5-10 kt are expected through the TAF period, likely becoming light and more westerly to southwesterly overnight. ~12 && .MARINE...Northwest winds around 10 to 20 kt with steep seas near 7 to 9 ft at 9 to 10 seconds driven mainly by a northwest swell continue today through early Wednesday. These northwest winds will increase significant wave heights towards 8 to 11 ft Tuesday morning. Seas will be highest over the outer waters, mainly north of Cape Falcon, with a 10-20% chance significant wave heights will peak slightly over 11 ft. Winds and seas will ease significantly Wednesday afternoon and evening, with benign conditions expected Thursday and Friday. Given steep seas and wind gusts upwards of 20 kt, a Small Craft Advisory is in effect for both the inner and outer waters through Tuesday night. Rough bar conditions are also expected within the main channel of the Columbia River Bar late Monday morning through late Tuesday morning with steep seas around 7 to 10 ft at 9 seconds and northwest winds around 10 to 15 kt. There is also a Small Craft Advisory on Tuesday morning for a strong ebb current and seas near 10 ft at the Columbia River Bar. ~12/23 && .PQR WATCHES/WARNINGS/ADVISORIES... OR...None. WA...None.

Key Points: *Localized AM frost possible east of the Cascades this morning. *A gradual warming trend is expected through Thursday. Dry weather is likely. However, weak instability and moisture may bring some cumulus build ups to southeast Lake County on Tuesday. *Breezy to gusty north to northwest winds are expected in the afternoons and evenings through Thursday. *Friday into Saturday, a weak high pressure ridge will bring warmer than normal temperatures and continued dry weather. Temperatures will peak on Saturday with highs around 5 to 8 degrees above normal. *Temperatures trend slightly cooler on Sunday as the ridge shifts east and a trough approaches. An upper low centered to the northeast over northern Montana will continue to shift eastward while a broad trough remains over the Pacific Northwest. Cool morning temperatures are expected for areas east of the Cascades and localized or brief frost may develop in the Klamath Basin and surrounding areas. Otherwise, expected mild daytime temperatures across the area today with dry weather with breezy to gusty afternoon and evening winds. Temperatures trend slightly warmer Tuesday. Additionally, a shortwave moves into the area from the northwest on Tuesday. This will bring a marine push into coastal areas and the Umpqua basin Tuesday morning with a very low chance for light showers (5%). Some weak instability and mid level moisture may result in some cumulus buildups over far southeast Lake County on Tuesday afternoon but chances for any showers or thunderstorms are very low (5%). Additionally, enhanced afternoon/evening northwest winds are expected Tuesday. Warm and dry weather is expected Wednesday. Temperatures trend slight warmer into Thursday, reaching near normal values. Another weak shortwave trough moving north of the area may result in enhanced afternoon breezes on Thursday and some cumulus buildups, mainly east of the Cascades and in Northern California. However, chances for showers or thunderstorms are forecast to remain very low (5% or less). Friday into Saturday, weak ridging develops across the region. This will result in a stronger warming trend. Temperatures are expected to peak on Saturday with highs 5 to 8 degrees above normal. High temperatures in the upper 80s to mid 90s are likely for most inland valleys on Saturday. Then, the high pressure ridge moves eastward on Sunday as an upper trough pushes in from the northwest, resulting in a slightly cooling trend and a potential for enhanced northwest breezes on Sunday. && .AVIATION...29/18Z TAFs...VFR levels persist across northern California and southern Oregon late this morning. Northerly flow continues to push clouds into Douglas and Coos counties. Ceilings at North Bend and Roseburg may periodically reach MVFR levels, but this is not generally expected during the day. The Umpqua Divide is keeping these clouds from traveling farther south. Some midlevel cumulus is developing over terrain in Jackson County. MVFR ceilings are possible along the coast and into the Umpqua Valley overnight. There`s a slight chance of these ceilings reaching Medford if the clouds can spill over terrain. Any MVFR ceilings that develop overnight look to dissipate by the end of the TAF period. -TAD && .MARINE...Updated 200 AM PDT Monday, June 28, 2026...Gusty north winds continue this morning, with very steep and hazardous seas from Gold Beach southward. North of these areas, incoming swell and north winds will maintain steep seas. This pattern will further strengthen Monday afternoon through Tuesday evening, with gales expected to develop south of Gold Beach. Elsewhere, northerly winds and strengthening northwest swell will continue steep seas through Tuesday evening. This pattern may persist into Wednesday. Winds ease slightly Thursday and Friday with improving conditions. && .MFR WATCHES/WARNINGS/ADVISORIES... OR...CA...None. PACIFIC COASTAL WATERS...Small Craft Advisory until 11 PM PDT Tuesday for PZZ350-356-370-376. Hazardous Seas Warning until 11 AM PDT Monday for PZZ356-376.

If there was available moisture with this passing perturbation, nocturnal thunderstorms would be possible. Interior valleys warm to the mid 80s to 90 degrees Monday afternoon. The northerly winds gusted in excess of 30 mph along the coast Sunday, with higher strength gusts along Cape Mendocino and Point St George. Very similar conditions as described will continue through mid week. The strong Pacific high responsible for this pattern begins breaking down Thursday. A weak trough may move through late Thursday through Friday, with little impact expected other than some potential light drizzle. Interior temperatures look to quickly rebound through next weekend behind the trough as a desert southwest high strengthens in advance of a stronger Pacific trough. There are high probabilities for high temperatures over 90 Saturday and Sunday for the interior valleys. Probabilities quickly lower for highs over 95 outside of a couple of the hottest valleys. This would result in some minor HeatRisk. && .AVIATION...Northerly winds eased overnight Sunday. The well-mixed and dry environment will extend the period of VFR conditions, with the exception of around Humboldt Bay. Some stratus formed around Humboldt Bay again, with MVFR to IFR ceiling levels. Coverage and duration of ceilings will be very limited from expected light easterly winds. Winds will continue to be the main concern as they quickly increase Monday, with gust 20 to 30 kts expected again at the coastal terminals. Higher gusts will occur near Point St George and CEC. && .MARINE...Strong northerly winds are over the waters while steep seas build in response. Gale Warnings remain over the outer waters, but gale conditions can be expected around Point St George and Cape Mendocino. The proximity of gale conditions to the inner zones will favor poorly modeled large to hazardous seas to pulse into the inner waters at times, as is being observed. The greatest threat for this will be over the late Monday, Tuesday, and Wednesday after maximum afternoon winds are achieved. A Hazardous Seas Warning has been issued to cover this threat given what was observed Sunday night. && .EKA WATCHES/WARNINGS/ADVISORIES... CA... None. NORTHWEST CALIFORNIA COASTAL WATERS...

Updated at 1200 PM PDT Sun Jun 28 2026 - Seasonally cool temperatures along with breezy afternoon winds persist into the middle of the week - Increased risk of sneaker waves and strong rip currents through Wednesday morning along the Pacific coast - Gradual warming trend begins late week and into next week && .SHORT TERM... Issued at 1222 PM PDT Mon Jun 29 2026 (This evening through Tuesday night) GOES-West visible satellite imagery reveals marine stratus hugging the Monterey Bay shoreline and points south while the vast majority of the San Francisco Bay Area is mostly clear. As of noon PDT, temperatures are generally running within a few to several degrees of what they were compared to this time yesterday. By the time the afternoon concludes, expect temperatures along to coast to peak in the upper-50s to 60s, warming to the 70s to to around 90 for inland communities. All-in-all, a very typical summer day. Western North America has been dominated by a long-wave trough with upper-low centered over the Northern Rockies. This troughing pattern will continue through much of the week with onshore flow prevailing for the Golden State. This will result in the usual marine stratus for coastal communities and near- to slightly cooler than seasonable temperatures inland. While inland temperatures are forecast to rise by a few degrees from Monday to Tuesday, coastal communities may reverse and cool as a result of the continued onshore flow. That said, forecast HeakRisk for the Bay Area and Central Coast will remain in the Low (green) to Minor (yellow) categories through the middle of the week. The risk of minor coastal flooding continues through Monday night along low-lying areas in the Pacific coast and the San Francisco and San Pablo Bays. The combination of thermal expansion within the Pacific ocean, a full moon on Monday, and southerly swell will account for a little over half a foot of surge over the astronomical tide. In addition, long-period southerly swell will continue to increase the risk for sneaker waves and strong rip currents along the Pacific coast, particularly at south and southwest facing beaches. A Beach Hazards Statement remains in effect through Wednesday morning, see the BEACHES section for more details. Never turn your back to the ocean! && .LONG TERM... Issued at 1222 PM PDT Mon Jun 29 2026 (Wednesday through next Sunday) The long-wave trough will gradually loose its grip over western North America by the end of the work week as a zonal flow re- establishes over the region. This will result in rebounding temperatures by Friday and Saturday with high returning to the 90s for the warmest interior communities. Cluster analysis of the ensembles suggests a building ridge over the Desert Southwest by early next week. There is still some variance in possible solutions, but something worth keeping an eye on for next week. Latest Climate Prediction Center guidance does give increased likelihood of above normal temperatures in the 8 to 14 day outlook. && .AVIATION... (18Z TAFS) Issued at 1003 AM PDT Mon Jun 29 2026 Currently a mixed bag of MVFR-VFR at the terminals with clearing making its way down the Pacific Coast. Moderate to high confidence in IFR-MVFR ceilings developing at bayshore and coastal terminals respectively tonight. Diurnal winds will prevail. Vicinity of SFO...Currently VFR with northeasterly flow. Winds will back through the morning to become westerly this afternoon. Moderate confidence on a ceiling returning to the terminal tonight, likely on the cusp of IFR/MVFR. Reasonable best case scenario is a donut hole develops over the terminal with stratus remaining confined on the north and west sides. SFO Bridge Approach...The San Mateo Bridge Approach has low probabilities (<30%) for developing a ceiling below FL045. Reasonable best case scenario is clouds remain confined to the terminal and northward. Vicinity of SJC and OAK...Currently VFR with southerly flow at both terminals. High confidence in VFR and diurnal winds prevailing at SJC. Moderate confidence in an MVFR ceiling developing at OAK tonight via a stratus feed through the Golden Gate Gap. Monterey Bay Terminals...Currently MVFR with southwesterly flow at MRY and MVFR with westerly flow at SNS. An otter eddy in the Monterey Bay will add some complexity and uncertainty in clearing times this morning; however, clearing is expected to continue along the Pacific Coast with high confidence in VFR by the afternoon. High confidence in IFR ceilings returning to both terminals tonight. && .MARINE... (Today through Saturday) Issued at 1003 AM PDT Mon Jun 29 2026 Strong to very strong northerly breezes will continue through Friday for the outer waters and the coastal jet region of Point Reyes, creating hazardous conditions for small craft. Frequent gale force gusts are expected across the northern outer waters and along the Point Reyes coastal jet region. Moderate to fresh northerly breezes will prevail elsewhere. Rough to very rough seas will continue through Wednesday before abating to become moderate to rough Thursday into Friday. && .BEACHES... Updated at 1225 AM PDT Sun Jun 28 2026 A Beach Hazards Statement remains in effect for the Pacific Coast Beaches through Wednesday morning as long period southerly swell returns to the coast, creating an increased risk of sneaker waves and strong rip currents, especially for south and southwest facing beaches. Hazardous beach conditions are advertised, specifically for moderate to steeply sloped beaches along the Pacific Coast of the North Bay, San Mateo, Santa Cruz counties. Sneaker waves will run up the beach much farther than other waves, potentially catching beachgoers by surprise and resulting in people being swept into the water. Rip currents are strong enough to pull the strongest swimmers away from shore. Swim near a lifeguard if possible. Stay back from the beach, and away from jetties, piers, beachside rocks, and other infrastructure near the water. Never turn your back to the ocean! && .MTR WATCHES/WARNINGS/ADVISORIES...

Through Monday evening, scattered showers and thunderstorms are expected over north ID and northeast WA. Cooler than normal conditions continue through the week with isolated mountain shower activity. By the weekend, a ridge will build bringing temperatures back up to normal in time for the holiday weekend. && .DISCUSSION... Tonight and Tuesday: The region is being influenced by a long wave trough pattern along the Pacific coastline with a Low over central MT. Wrap around bands, from the Low, will continue to bring showers and isolated thunderstorms to portions of the region. Cape values are in the 500 plus J/KG. The best chances are North ID and Northeast WA with a 20-30% chance through 11 PM PDT. Areas from the Okanogan Valley, north of hwy 2, and to the ID/MT border have a 10-20% chance. Main impacts will gusty winds, infrequent lightning, brief heavy rain, and small hail. Outside of thunderstorms, these areas have at least a 50% probability of a tenth or greater rainfall. The threat will decrease has the Low continues to drift East overnight. Tuesday will similar to Monday but area will be drier and more stable. Early stratus clouds through the morning and clearing by the afternoon. Instability is weaker with only 200-300 J/kg of Cape along the northern mountains. An isolated thunderstorm is possible but chances are less than 15% for the afternoon and early evening. Afternoon winds will continue to breezy through the Cascades Gaps with sustained in the teens and gusts in the upper 20s and low 30s mph. Highs will be in the upper 60s and low 80s. Overnight lows will be in the 50s tonight. The drier air will cool Tuesday night with lows in the 40s. Wednesday through Friday: The trough pattern will continue through the period but a off shore High will begin to nudge into the region. It will push the moisture further North and promote a warming, drying trend through the end of the week. Clusters show a quick moving trough moving the region Friday afternoon. It brings increased thunder chances(5-10%) to the Inland Northwest. It will be something to keep an eye for the start of the upcoming holiday weekend. Any chance of precip will be over the mountains with little to no accumulation expected. Afternoon winds will continue to be breezy through the Cascade Gaps. Highs will be in the 70s to low 80s on Wednesday and upper 70s and 80s by Friday. Overnight lows will be in the 40s to low 50s.

Overnight lows will be in the 50s to low 60s. /JDC && .AVIATION... 18Z TAFs: MVFR stratus is slowly dissipating for the GEG/KSFF/COE areas. For the afternoon attention turns to scattered showers and thunderstorms developing over the northern mountains, with a 20 percent chance of thunderstorms impacting KGEG/KSFF/KCOE between 21z-04z. Thunderstorms today will be capable of producing brief downpours, small hail, and wind gusts up to 35 MPH. A combination of rain saturating the boundary layer and low level upslope will continue to promote IFR/MVFR stratus this morning at KPUW, KCOE.

This is in response to an upper level low pressure currently over Montana, that will continue to depart to the northeast and into southern Manitoba over the next 24 hours. A weak, transient ridge of high pressure is beginning to break up earlier cloud cover through the Columbia Basin, but an incoming shortwave will return clouds overnight into Tuesday. These synoptic features have also allowed a pressure gradient to develop along the Cascades to attribute to breezy conditions across the Columbia Gorge, east slope of the Cascades, Lower Columbia Basin, and the Kittitas Valley. The weak shortwave stalls along the coast overnight tonight before slowly passing through the area Tuesday followed by a second shortwave on Wednesday. The first shortwave will erode the backside of the transient high pressure ridge, which will provide enough instability for isolated thunderstorm development across the east and south edges of Grant, Union, and Wallowa Counties. Enough moisture should be present in any developing storm cells to provide wetting rain amounts (>0.10"). Wednesday`s system is expected to be much drier as the shortwave stays further north and passes along the Canadian border. This should only lead to an uptick in cloud cover and afternoon winds. Flow aloft turns from the northwest to more westerly Thursday, then more from the southwest Friday into Saturday, which initiates a warming and drying trend through the latter half of the week. Below normal high temperatures will become near to above normal values on Saturday, with highs breaking into the low to mid-90s across portions of the Lower Columbia Basin on Sunday. These high temperatures, coupled with overnight lows only dipping into the mid-to upper 50s, will attribute to isolated pockets of moderate HeatRisk across the Lower Columbia Basin and northern Blue Mountain foothills Sunday and Monday. However, guidance is not in full agreement regarding how enhanced the southwest flow aloft and upper level ridge will be over the weekend. At this time, 80% of ensemble members advertise a similar or slightly cooler outcome. The 20% warmer outcome is rather substantial though, suggesting Sunday`s high temperature being 5 degrees warmer than the current forecast. This may be an outlier as 27% of ensemble members were suggesting this warmer outcome just 24 hours ago. Further analysis of this trend is necessary, which may lead to more areas of moderate HeatRisk Sunday. Stay tuned. 75 && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... VFR conditions currently at all sites, which will stay the course through the period. Breezy conditions at most terminals as gusts of 20-30kts will be possible. KRDM/KBDN are the only sites that will experience lower winds of 5-15 kts. Winds subside through the evening, but will stay elevated between 15-25kts through Tuesday morning. 75 && .FIRE WEATHER... Minimal fire weather concerns this week as early week winds will be accompanied by afternoon humidities between 35-45% with excellent overnight humidity recoveries of 70-85%. There is a slight threat for isolated thunderstorms across Grant, Union, and Wallowa counties Tuesday, but chances are minimal as coverage is confined to the south and east of OR 693, 694, and 695. Minimum humidities trend lower toward the end of the week and through the weekend, but winds should stay rather light as upper level ridging develops. 75 && .Preliminary Point Temps/PoPs...

Transient low pressure to the west will maintain mild temperatures today with daytime highs in the 60s and 70s. A relatively more favorable overlap of instability and moisture will support a low probability of showers and isolated storms from Alpine-Mono counties into S.Lyon-Mineral counties this afternoon. A stray afternoon shower may also develop near the Tahoe Basin, but confidence is low. A persistent troughing pattern remains in place throughout the week, allowing temperatures to slowly warm to late June standards leading up to the holiday weekend. While most areas will stay dry this week, each afternoon will feature low chances (10% or less) of an isolated shower or a stray thunderstorm. Winds will become breezy each afternoon this week -- especially Tuesday and Thursday -- but winds aren`t expected to be stronger than our typical zephyr breeze. Still, breezy conditions may pose minor impacts to fire and recreation at times. The Independence Day weekend is trending towards being a hot one as temperatures sharply warm-up in response to building high pressure. Daytime highs are slated to breach the 80s for Sierra communities and 90s across NE CA/W NV valleys over the weekend. While there is no strong signal for widespread thunderstorm activity this weekend, warming surface temperatures tend to support at least some potential for thunderstorms across the higher Sierra terrain. If you have outdoor plans to celebrate the holiday, be sure to frequently check the latest forecast. -Salas && .AVIATION... VFR conditions and typical afternoon breezes prevail today with a low 10-15% chance of showers and thunderstorms near KMMH between 20Z and 06Z.

Area of concern along and west of the I-5 corridor in the Sacramento Valley. - Chances for isolated mountain thunderstorms this afternoon/evening; best chances south of I-80. - Cooler temperatures and breezy onshore flow expected Tuesday onward. && .DISCUSSION... An upper level low is positioned directly over interior NorCal this afternoon. Most of the Valley is still experiencing north winds at the time of this writing, with Red Bluff AP observing a gust of 26 kts. North winds expected to continue through the rest of the morning into the early afternoon. Positioning of low will allow some forcing/lift along the Sierra crest this afternoon, where a slight chance (10-15%) of a thunderstorm is possible. The best chances will remain mainly south of I-80. Low is forecast to dig further south then east tomorrow, prompting slight enhancement of onshore flow and lowering of high temperatures. NorCal looks to retain some upper level troughing influence as we move through the middle of the week. High temperatures will remain slightly below late-June early July normals through Thursday. By the weekend, upper level troughing breaks down slightly as high pressure builds in the Pacific and in the desert southwest. High temperatures will respond by returning to normals Friday and through the July 4th Holiday weekend. Triple digit highs are in the forecast for the northern Sacramento Valley on July 4th, however with the relatively cooler temperatures we have experienced lately and overnight lows in the upper 50s to mid 60s will keep Minor HeatRisk in the forecast the next 7 days. && .AVIATION... VFR conditions are expected over the next 24 hours. There is a 10-15% chance for isolated mountain thunderstorms south of I-80 in the Sierra this afternoon/evening which may lead to isolated MVFR/IFR conditions.

KEY MESSAGES: - Flooding of small streams and creeks due to ongoing heavy rain is imminent or occurring in the Mission valley and in Glacier National Park - Strong showers and thunderstorms capable of rainfall rates of 0.50" to 0.75" per hour possible for locations along and north of I90 in northwest Montana through this evening - Widespread heavy rain tapers off late tonight, however an active pattern supportive of showers and thunderstorms with locally heavy rain continues through Friday Widespread prolonged rainfall continues this afternoon as anomalous moisture (200 percent of normal) continues to rotate around an upper level low pressure system moving slowly through central Montana. Observed 24 hour precipitation amounts of 1 to 2 inches of rain are common across much of western Montana and north central Idaho with focused amounts of 3 to 6 inches occurring in the higher terrain along the Continental Divide in Glacier National Park as well as the Mission and Swan Ranges. With additional amounts of 1 to 3 inches of rain possible through Tuesday morning in these locations, areal flood warnings have been posted for small streams and creeks of Glacier National Park and in the Mission valley. High resolution forecast models show an area of instability through portions of Sanders, Lake, Lincoln, Flathead and Missoula counties this afternoon and evening, which may allow for convective precipitation (thunderstorms and strong showers) to develop. This activity will be capable of 0.50 to 0.75 inch per hour rainfall rates, which could accentuate ongoing flooding or potentially impact additional flood prone basins/burn scars. Precipitation intensity is expected to decrease late tonight into Tuesday morning as the low pressure system exits the region. However, a general trough with a wave of energy will move through the region Tuesday afternoon and evening. Anomalous moisture will remain in the atmosphere, which may allow for thunderstorms capable of localized heavy rain. This will mainly be focused through Idaho county, Lemhi County and southwest Montana. A moderating trend is expected later this week with possible thunderstorms each day. With the added low-level moisture from all the rain, this could enhance instability each day through Friday. && .AVIATION...Low pressure continues to spin east of the Continental Divide this afternoon, sending wraparound moisture into the Northern Rockies airspace. Precipitation will continue, lowering visibility and ceilings into Tuesday morning. Heavier rainfall producing short bursts of 0.50 inches per hour rates will last through about 30/0400Z, reducing visibility down to IFR at times. Expect terrain to be obscured over the entire Northern Rockies airspace well into Tuesday. Fog could also form over KMSO and KGPI early Tuesday morning, though confidence was not yet high enough to include fog in the 29/1800Z TAFs. && .MSO WATCHES/WARNINGS/ADVISORIES...

Light showers will continue across the area through this evening under lingering moisture and weak dynamics on the back side of the departing low pressure system. As the upper level support departs, skies are expected to clear overnight, allowing temperatures to reach about 5 degrees below normal values. A shortwave passage is on track for Tuesday afternoon and will combine with residual low level moisture and weak instability to support isolated thunderstorm development. High resolution models indicate a few storms will initially develop across Malheur and Baker County Tuesday afternoon before tracking eastward into southwest Idaho during the late afternoon and early evening hours. The main threats with these storms will be gusty outflow winds and lightning. By Wednesday, the shortwave exits to the east, bringing mostly clear skies back to the region. Daytime heating will lead to cumulus clouds developing over the higher terrain by the afternoon. While most of the forecast area will remain dry, isolated thunderstorms are possible (20% chance) along the Idaho/Nevada border and across the central Idaho mountains where moisture and instability remain sufficient. Temperatures will gradually warm through the short term period, reaching the low 80s in the Western Snake River Basin by Wednesday. && .LONG TERM /Thursday through Monday/... Continued troughing will remain over the region Thursday and Friday, with the last of the embedded shortwaves moving through Thursday into Friday. This final push will bring isolated showers and thunderstorms across the higher terrain of SW Idaho, and cooler than normal conditions through the end of the week. Over the weekend, the Four Corners ridge look to intensify, brining higher geopotential heights and rising maximum daily temperatures. This will bring temperatures back up to near normal. The timeliness of warming (but not too warm) temperatures and dry conditions should make for a pleasant Fourth of July. There is an outside chance (10-20% probability) of temperatures exceeding 95 degrees on July 4th through the lower Snake Plain. Ensembles hint that on Sunday and Monday, the region will develop southwesterly flow aloft between weak troughing moving into the Pacific NW and the persisting Four Corners ridge. This would continue the warm trend, with showers and thunderstorms coming back into the forecast. && .AVIATION /18Z Monday through Tuesday/... Issued 1157 AM MDT MON JUN 29 2026 Generally VFR.

(This evening through next Monday) WEATHER PATTERN OVERVIEW: Current conditions across the area are sunny and calm, with satellite imagery showing only a few high clouds across northern Nevada. Persistent ridging over the eastern US will slow the retreat of the trough over the West but a slow warming trend is still expected, with highs in the 70s today increasing to the 80s by Friday. Conditions will mostly remain dry during this time, although a weak low center riding the trough on Wednesday could spark some isolated showers and thunderstorms in northern Elko county. Winds will mostly be light, with the exception of Thursday when breezy conditions develop in central Nevada. The high to the east diminishes by the weekend, allowing the upper air pattern to progress and ridging to begin to return to the West. This will allow temperatures to spike for the holiday weekend, with temperatures reaching the mid 90s and some early, low confidence, excessive heat indicators developing. Heat is expected to continue into next week, with highs in the mid 90s and breezy conditions returning in central Nevada. FORECAST CONFIDENCE & DEVIATIONS: High confidence in increasing temperatures through the weekend, however confidence in excessive heat potential Saturday and Sunday is low. Low confidence in shower and thunder potential on Wednesday, and moderate confidence in quiet conditions for the rest of the forecast. No changes were made to base NBM output. && .AVIATION...VFR conditions and winds less than 10KT at all sites today. && .FIRE WEATHER...Low fire weather conditions are expected today and tomorrow due to humidity around 20% in northern Nevada and light winds across the area. Conditions dry out starting Wednesday, in connection with a warming trend. Elevated conditions are expected for Thursday due to wind gusts 20-25 mph, with about a 20% chance of winds increasing to above critical thresholds. Winds die down again Friday through Sunday as temperatures continue to warm. && .LKN Watches/Warnings/Advisories... None. && $$ DISCUSSION...94 AVIATION...94 FIRE WEATHER...94 |
