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.

535 FXUS66 KPQR 291757 AAA AFDPQR Area Forecast Discussion...UPDATED National Weather Service Portland OR 1057 AM PDT Mon Jun 29 2026 Updated Aviation Discussion... .SYNOPSIS...Cool onshore flow and persistent cloud cover will maintain below average temperatures over the area through Thursday with little change in the overall weather pattern. 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...Now through Sunday night...Very little change is expected to the overall weather pattern Monday through Thursday. Model ensemble guidance continues to suggest cool onshore flow will 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 (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 over the weekend are generally under 10%, except on Sunday when chances increase to 10-20%. 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 we wind up in the 80s or lower 90s. -23 && .AVIATION...Currently as of 18Z Mon, widespread cloud cover bringings IFR/MVFR conditions along the coast and a mix of MVFR/VFR CIGs inland. By 19-21Z Mon, expect prevailing VFR conditions inland and prevailing MVFR conditions along the coast. With a 40-70% chance of MVFR CIGs at coastal terminals through the TAF period, brief VFR CIGs may occur. Around 12Z Tue to the end of the TAF period, there is a 30-40% chance for MVFR CIGs at inland terminals. Otherwise, expect generally northwesterly winds around 5-10 kt during the afternoon, becoming light and westerly to southwesterly overnight. KPDX AND APPROACHES...Current MVFR CIGs will improve to VFR by 19-20Z Mon, likely lifting to above 4000 ft through the afternoon. There is a 20-30% chance for MVFR CIGs to return by 12-15Z Tue and persist through the morning. 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 seconds driven mainly by a fresh northwest swell will continue on Monday. Although weak high pressure will be building over the waters, northwest winds will continue to build the ongoing northwest swell with significant wave heights increasing slightly to 8 to 11 ft Monday afternoon. Seas will be highest over the outer waters. There is a 30-50% chance significant wave heights will peak slightly over 11 ft beyond 40 NM offshore on Monday, mainly to the north of the Columbia River Bar. Northwest winds and a fresh northwest swell then continues Tuesday through Wednesday morning, maintaining steep seas and hazardous conditions for small craft. 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 evening. 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 with northwest winds around 10 to 20 kt. A strong ebb current will occur Tuesday morning, which is when seas are expected to peak near 10 ft. As such, a Small Craft Advisory has been issued for the Columbia River Bar. -23 && .PQR WATCHES/WARNINGS/ADVISORIES... OR...None. WA...None.

366 FXUS66 KMFR 291755 AFDMFR Area Forecast Discussion National Weather Service Medford OR 1055 AM PDT Mon Jun 29 2026 .DISCUSSION... 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.

615 FXUS66 KEKA 290722 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 1222 AM PDT Mon Jun 29 2026 .SYNOPSIS...Seasonably warm and dry conditions will build through midweek with gusty north wind along shore each afternoon. && .KEY MESSAGES... -Gusty north winds each afternoon along shore through mid week. -Gradual warming and drying trend. -Temperatures turn hotter over the holiday weekend .DISCUSSION...Temperatures warm Monday behind a dry, southward passing shortwave disturbance. 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...

014 FXUS66 KMTR 291928 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 1228 PM PDT Mon Jun 29 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... 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...

291 FXUS66 KOTX 291755 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 1055 AM PDT Mon Jun 29 2026 .KEY MESSAGES... - Wetting rains into Monday for eastern WA and north ID including over 1.00" of rain in the mountains of ID. - Thunderstorms in northeast WA and north ID Monday afternoon and evening. - Warmer and drier for the end of the week && .SYNOPSIS... On Monday afternoon and 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... Monday through Tuesday: Bands of rain are moving through the Inland Northwest and will continue to do so through late Monday night, with the exception of the Northern Mountains and the Idaho Panhandle. For much of the area, these rains will be beneficial, with ~0.10 inches expected from Colville down to Spokane and eastward. Highest rainfall totals will be seen in the Idaho Panhandle due to its closer proximity to the upper level low. Rainfall totals in Shoshone County could reach 1.0 to 1.25 inches. In addition to the rainfall, in the afternoon and evening there is a chance (20 to 30 percent) for thunderstorms due to elevated instability in the Northern Mountains, northern ID Panhandle. There is a lesser chance in the Spokane/Coeur d`Alene area (10 to 20 percent). High-res models favor a couple hundred Joules of CAPE, high PWATs of over 1 inch, and slow storm motion at around 10 kts. When combining high PWATs with low storm motions, main concerns with thunderstorms will be isolated heavy rainfall alongside small hail and lightning. This will be monitored closely for any flooding issues, alongside any storms that pass over burn scars. Maximum temperatures across the Inland Northwest remain lower than normal by 5-10 degrees and will remain in the low 70s to low 80s. Minimum temperatures also remain below normal in the low 40s to low 50s. Wednesday through Friday: The middle to the end of the work week will be relatively dry apart from showers in the mountains due to orographic lift as lower heights remain over the area. Temperatures will continue to be cooler than normal, though a weak ridge moving closer to the coast near the end of the week will allow for some warming. Holiday Weekend: Clusters near the holiday weekend begin showing signals for said ridge strengthening and moving through the forecast area, supporting a warmup. Saturday, July 4th, shows temperatures in the 80s alongside breezy winds and low relative humidity. On Sunday, temperatures are projected to get into the high 80s and low 90s, which will bring a return of isolated Moderate HeatRisk to the area. /AS && .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. For KGEG/KSFF forecast leans towards VFR conditions persisting. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence VFR conditions persist through the TAF period at KEAT/KMWH. Moderate confidence of VFR conditions at KGEG/KSFF this morning. Thunderstorms producing gusty outflow winds and brief heavy rain may result in TAF amendments this afternoon and evening at KGEG/KSFF/KCOE, but with 20% chances did not mention in the TAF for now. /JDC ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports, please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard && .Preliminary Point Temps/PoPs...

Deep northerly flow is seen in the satellite data overnight as the area ins on the backside of the upper low now lifting across northern Montana and with SPC analysis indicating some weak moisture transport across eastern Washington with mid level clouds and light rains overspreading much of this area. Gradient induced wind gusts continue between about 25 an 35 mph across the Columbia Basin overnight and are forecast to continue the pattern through the day. Winds across the Kittitas valley look to have a weakening trend in the afternoon based on probabilities of gusts to 40 mph at 7 AM around 80% but falling to around 30% by 2 PM before up ticking in the evening to around 50%. A similar trend can be expected across the Eastern Columbia River Gorge, and the Foothills of the Blue Mountains/Oregon Columbia Basin Today and This Evening. Mid level clouds and showers will linger across southeast WA and the Oregon Blue Mountains/Wallowas though about mid afternoon while breaks of direct insolation will be found farther west and afternoon high climb back into the 80s for sections of the Lower Columbia Basin/Yakima Valley. Although weak synoptic troughing lingers across the region into Tuesday, the wind will be much lighter on Tuesday, and the character of the day drier and warmer. Winds may still be noticeably breezy to windy across the Eastern Columbia River Gorge and Kittitas Valley but more tied to locally terrain than a widespread wind episode. Toward the end of the week, enough similarity exists between the ensembles clusters to bring fairly high confidence in any precipitation over the July 4th Holiday weekend would be relegated to the higher terrain/mountain zones an light (only a few hundredths of an inch over a 24 hour period). Additionally these clusters show little in the way of MUCAPEs, which would point to showers rather than risk of anything more than isolated thunderstorms. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... VFR conditions currently at all sites, which will stay the course through the period. Light rain still impacting KPSC/KPDT/KALW over the early afternoon before drier conditions return as ceilings lift to 25kft this evening. 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... Breezy conditions Today could impact any fire ongoing. The breezy conditions will begin to wane this afternoon leaving Tuesday with much lighter winds across the greater area. Tuesday can still see some locally breezy to gusty conditions across the Eastern Columbia River Gorge and Kittitas Valley. The cooler conditions Today will continue to mitigate the overall impact of relative humidity (keeping it elevated). An isolated thunderstorm cannot be ruled out over eastern Wallowa county Tuesday afternoon (less than 20% chance).

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. Expect similar conditions Tuesday, except with lower shower/storm chances and a slight uptick in afternoon breezes. -Salas && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$

706 FXUS66 KSTO 291922 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 1222 PM PDT Mon Jun 29 2026 .KEY MESSAGES... - Elevated fire weather conditions today due to north winds and low daytime RH. 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. North winds with gusts 15 to 25 kts in the northern/central Sac Valley until 00Z Tuesday. West-southwest gusts 15 to 20 kts in the Delta from 23Z Monday through 18Z Tuesday. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$

236 FXUS65 KMSO 290852 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 252 AM MDT Mon Jun 29 2026 .DISCUSSION... KEY MESSAGES: - Potential for rapidly rising water levels in small creeks and streams across northwest Montana this afternoon and evening, due to heavy rain showers and thunderstorms. Localized rockfall and/or debris flows are possible as well. - Hypothermia risk continues through the day Monday in the backcountry. - Near seasonable temperatures along with daily thunderstorm chances are possible Tuesday through Friday of next week. Satellite and radar observations show a large low pressure system spinning over central Montana, near Great Falls this morning, that is spreading moderate to heavy rainfall across western Montana. Moderate snowfall is also occurring for elevations above 6,500 feet across the Northern Rockies. As such, Winter Storm Warnings remain in effect through mid-morning. Along with impassable backcountry Forest Service roads, the risk for hypothermia for unprepared recreationists remains due to the cold and wet conditions. Rainfall totals over the past 36 hours ending this morning have ranged between 0.30 to 1.50 inches across the Northern Rockies. The highest totals have fallen in the terrain along the Continental Divide from the Canadian Border, south to Butte. Several inches of snow have also been reported across the region with 6 inches at Lost Trail Pass, 7 inches near Porters Corner in Granite County, Montana, and 8 inches near Cobalt in Lemhi County, Idaho. Widespread moderate to heavy rain at times will continue through mid-morning today. Rainfall rates this morning will generally range from 0.10 to 0.20 inches per hour. These rates are expected to increase later this afternoon and evening, when heavy showers and thunderstorms develop between 2 PM and 10 PM. During this time, rates of 0.50 inches per hour or more are expected under the heavier showers. The latest forecast ensemble models show additional rainfall totals through Tuesday morning ranging between 0.75 and 1.50 inches across the Northern Rockies. The higher terrain along the Continental Divide and the Mission Range has additional expected amounts of 1 to 2 inches. Some of these totals account for the potential for heavy rainfall with scattered thunderstorms this afternoon and evening, so not everyone will see these higher amounts. This will be on top of what has already fallen. Small streams and creeks may experience rapid rises this evening with the expected additional rain, along with the threat for rockfall and/or debris flows. The highest risk for these impacts is most likely to occur in the higher terrain along the divide and the Mission Range, north of Missoula. Additional Flood Watches may need to be issued this morning to account for these risks. Given the widespread precipitation, fog and low clouds could cause travel issues across the region Tuesday morning. The lingering moisture will also support scattered showers later in the day. 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. && .AVIATION...Satellite and radar observations show a large low pressure system spinning over central Montana, near Great Falls this morning, that is spreading moderate to heavy rainfall across western Montana. Moderate snowfall is also occurring for elevations above 6,500 feet across the Northern Rockies. The widespread rainfall will periodically reduce visibility and ceiling for all aviation sites throughout the day, along with mountain obscurations. This afternoon heavier showers and scattered thunderstorms are expected to develop between 29/2000Z and 30/0400Z this evening. These showers and thunderstorms will be capable of producing short bursts of 0.50" per hour rainfall rates as they pass overhead. KGPI, KMSO, and KHRF will have the highest risk for these heavier showers. Given the recent widespread precipitation, fog and low clouds could cause travel issues across the region Tuesday morning. Afternoon showers will remain in the forecast, through the widespread persistent precipitation will have ended by sunrise Tuesday. && .MSO WATCHES/WARNINGS/ADVISORIES...

945 FXUS65 KLKN 291947 AFDLKN Area Forecast Discussion National Weather Service Elko NV 1247 PM PDT Mon Jun 29 2026 .KEY MESSAGES... * Dry this afternoon with high temperatures in the 70s * Showers and thunderstorms Wednesday in Elko county * Temperatures trend warmer through the week && .DISCUSSION... (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
