638 FXUS66 KSEW 021749 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 949 AM PST Mon Nov 2 2026 .SYNOPSIS... Dry conditions will continue across western Washington through this afternoon. A weak system will brush the region tonight, bringing chances of light rain to the area into early Tuesday. The weather pattern becomes more active mid to late week as a series of systems brings lowland rain, mountain snow, gusty winds, and the potential for high surf to western Washington. A brief break in the unsettled weather is possible Friday night into Saturday, before the next round of unsettled weather moves in late in the weekend. && .SHORT TERM /TODAY THROUGH WEDNESDAY NIGHT/... Satellite imagery shows another round of low stratus and fog developing across the interior lowlands early this morning. Expect low stratus/fog to continue to increase in extent through the early morning hours before scattering by late morning into early this afternoon. A few areas may see fog become dense, with visibilities dropping down to around a quarter mile or less at times. Dry conditions will continue across western Washington through this afternoon as an upper level ridge pushes inland across the Pacific Northwest. A weak, splitting system offshore will then brush the region tonight into early Tuesday and will bring slight chances of showers to the area. The most likely areas to see any precipitation are the Pacific coast, Olympic Peninsula, and areas primarily north of Everett. Conditions will dry out across western Washington again by Tuesday morning, making for a another mostly dry day for many spots. Precipitation chances will increase midweek as the first in a series of weather systems moves across the area on Wednesday. This first system will bring more widespread rain and high elevation snow to western Washington, with the bulk of the moisture focused over the Olympic Peninsula and the North Cascades. Rainfall amounts for the Pacific Coast are expected to range between a quarter of an inch to half an inch. Many spots across the East Puget Sound lowlands will get rain shadowed, with only a few hundredths of an inch expected for most areas. Snow levels generally hovering near 5500 ft will bring a few inches of snow to the higher peaks of the Olympics and North Cascades. Winds will also increase as this system approaches the area, with southerly winds expected to pick up along the coast during the late morning to early afternoon hours and increasing across the interior during the evening hours. Winds will be the strongest along the Pacific Coast, with the most likely scenario at this time highlighting wind gusts reaching 25-35 mph. Winds across the interior will increase to 10-20 mph, with gusts to 25-30 mph possible. Winds will ease again overnight into Thursday. && .LONG TERM /THURSDAY THROUGH SUNDAY/... Precipitation will gradually taper across the area during the day on Thursday, however a stronger system will move into the area Thursday night into Friday. This system will bring another round of gusty winds, lowland rain, high elevation snow, and the potential for high surf along the Pacific Coast. The bulk of the moisture with this system will remain aimed at the Olympic Peninsula and the North Cascades, with the highest rainfall amounts likely being along the North Coast, where half an inch to an inch of rain is expected. Many areas across the interior lowlands will be rain shadowed again and generally look to receive a couple hundredths of an inch to a quarter of an inch of rain. Snow levels between 4500-5000 ft will bring some additional snowfall to the higher peaks of the Olympics and North Cascades. Winds will become gusty as the system approaches, with latest probabilistic guidance indicating a 50% chance of wind gusts exceeding 40 mph along the Pacific Coast and a 40-50% chance of wind gusts exceeding 40 mph for areas from Whidbey Island northward. Increasing potential for high surf along the coast could also bring localized beach erosion to coastal communities and create hazardous conditions for beachgoers. Ensemble clusters continue to hint at a brief break in the unsettled weather Friday night into early Saturday as a ridge of high pressure temporarily moves back over the region. Discrepancies remain in regards to the amplitude of the ridge over the area at this time, however it does look to aid in directing the bulk of the moisture of the next incoming system more into British Columbia. The ridge does look to push inland rather quickly though, which would open the door for the system impacting British Columbia to move into the area by Sunday. 14 && .AVIATION... High pressure will slowly drift east with a weak front remaining offshore through the period. Satellite and cameras this morning shows a mix of low MVFR or IFR/LIFR in stratus and fog. Expect conditions to slowly improve later this morning, and by the early afternoon most places will likely improve to VFR - with some locations seeing localized MVFR. The coastal terminals have a 20 percent chance of showers later this afternoon and evening. Remaining terminals will likely stay dry. Higher clouds likely remain overnight tonight, and keep low ceiling/fog potential limited to the south interior. Winds at the surface will generally flow out of the southeast, with winds of 5-10 kt in the mountains/coast, and 5 kt or less in the interior. KSEA...LIFR in fog this morning. Conditions will slowly improve to VFR around 19z/20z as high clouds start to filter in. VFR conditions for the remainder of the TAF period. Light southeast winds at 5 kt or less, with a switch to NE winds this evening, but remaining generally light. HPR/Mazurkiewicz && .MARINE... High pressure will slowly drift eastward today with a front remaining offshore in the coastal waters. This will result in some breezy winds in the far outer coastal waters up to 20 kt. The pattern will become active again from Wednesday through the weekend as an atmospheric river pattern begins to take shape, The first system on Wednesday will primarily bring wind impacts to the coastal waters, with a 60-80% chance of winds gusts over 20 kt. The next system on Friday will be stronger, with gusty winds covering the coastal and the interior waters as southerly winds increase with the system passing through. There is a 25-40% chance of gale gusts in the coastal waters and the east Strait of Juan de Fuca. 2 additional systems may also impact the waters through the weekend and early next week, with again chances for wind gusts over 20 kt. A small craft advisory continues for seas of 8 to 11 ft in the coastal waters/west Strait of Juan de Fuca. Seas will decrease to 6- 8 ft on Tuesday before building back to 10 ft to 13 ft Thursday, and further increase to 15 to 20 ft on Friday before decreasing back to 11 to 15 ft next weekend.

208 FXUS66 KPQR 022207 AFDPQR Area Forecast Discussion National Weather Service Portland OR 207 PM PST Mon Nov 2 2026 .SYNOPSIS...Mostly dry conditions likely persist through Tuesday as a weak frontal boundary grazes the coast to the west. Then, after ample inland fog/low clouds to start Wednesday, an active and wetter weather pattern returns late Wednesday through the end of the week and beyond. However, weather related impacts over the next 5-7 days remain fairly limited, staying within climatological norms for early November. && .DISCUSSION...Now Through Sunday...An upper-level ridge of high pressure continues to progress eastward this afternoon with weak offshore flow helping to scour out a much wider swath of low clouds/fog compared to this time yesterday. Still, the inversion and low clouds have remained persistent from roughly Salem/Albany southward. It may take until the late afternoon for the south Willamette Valley to see improvement. Otherwise, both satellite and radar observations are also depicting a weak system brushing the coastline which is responsible for some of our added high clouds and filtered sunshine for the locations devoid of low stratus/fog. There is a 10-15% light precipitation brushes the north Oregon coast towards the Long Beach Peninsula/Willapa Hills this evening, but more likely the dry conditions hold. Come Tuesday the low pressure system off the northern California coast moves east, remaining south of the forecast area while dragging a broader weak large scale trough feature overhead by the late afternoon and evening. That said, models are in good agreement in dry weather persisting. Before the axis of this feature is able to move inland, the resulting offshore surface pressure gradient likely peaks Tuesday morning with continued breezy east winds through the Columbia River Gorge and Cascade gaps before weakening late in the day - the NBM gives a 40-55% chance for max gusts to exceed 40 mph in the western Gorge. At least the weak troughing moving overhead, cooling temperatures in the mid-levels Tuesday afternoon should weaken the temperature inversion and help any lingering low cloud/fog clear out by the afternoon. On Wednesday, a shortwave trough moving across the NE Pacific quickly pushes a frontal system toward the coast later in the day. Conditions appear rather conducive to fog and low stratus formation again to start the day, followed by increasing precipitation chances across the area in the afternoon through Wed night. Most ensembles indicate this system will be weakening with just light amounts of rainfall, most likely 0.1-0.30" coast range, <0.10" inland valleys. Cluster analysis of 500 mb heights are in relatively good agreement heading into the latter part of the week with zonal to southwest flow aloft allowing for a somewhat active pattern over the NE Pacific to approach the coast. By the weekend, ensembles are in decent agreement depicting a broader ridge axis building east of the Cascades. There is still quite a bit of uncertainty in regards to exact rainfall coverage and amounts, but there is continued potential for multiple rounds of systems moving across the area into next weekend. At this point, no significant precipitation impacts are expected with any of these weather systems over the next 5 to 7 days, and snow levels hold around 5000-6000ft. However, beyond day 7 into next week (11/10-11/14), almost all ensemble systems like the EPS, GEFS, etc. are beginning to show a growing consensus for a much more impactful and active weather pattern - a period of time we`ll have to watch closely. -99/DH && .AVIATION...Through 00Z Tuesday...Satellite imagery and terminal observations as of early Monday afternoon depicts predominately VFR conditions with increasing high clouds across northwest Oregon and southwest Washington. Tonight, expect these trends to continue for most terminals. An exception would be KHIO and KEUG, where there is a 15-30% chance for IFR/LIFR CIGs/VIS at any given hour between 12-18z Tue. Light northerly winds under 5 kt expected across the central and southern Valley today. Elsewhere, offshore pressure gradients will support increasing easterly winds along the coast and eastern Portland Metro Area, with gusts up to 22-24 kt at KTTD. KPDX AND APPROACHES...Predominately VFR conditions through the TAF period with high clouds. Easterly winds around 3-5 kt. -10 && .MARINE...Light east to southeast winds continue through this evening as a low pressure system remains well offshore. A long period west-northwest swell will maintain seas around 8 to 10 feet at 14-17 seconds through Tuesday. Will keep the Small Craft Advisory for the outer coastal waters up for now, however, seas are marginally hitting small craft conditions, so this Advisory could potentially be dropped early if seas end up falling. This long period swell will also result in a moderate threat for sneaker waves at the coast today through Wednesday. Caution should be used at beaches when in or near the water. Winds become light and variable on Tuesday, then turn more southerly by Wednesday ahead of an approaching frontal system. This system is expected to be relatively weak, with around a 50-60% chance for wind gusts up to 25 kt north of Cape Falcon. By the end of the week, model guidance hints at a stronger system entering the waters, resulting in a 50-70% chance for maximum wind gusts exceeding 34 kt north of Cape Falcon on Friday. In addition, another long period westerly swell will likely build seas into the mid-teens with a 10-20% chance for significant wave heights exceeding 20 ft. -10/DH && .PQR WATCHES/WARNINGS/ADVISORIES...

669 FXUS66 KMFR 021914 AFDMFR Area Forecast Discussion National Weather Service Medford OR 1114 AM PST Mon Nov 2 2026 ...Updated the Aviation and Marine Sections... .AVIATION....02/18Z...Low ceilings are lingering late this morning in the Umpqua Valley, including Roseburg(KRBG). Improvement to VFR is expected around 20-21Z. Otherwise, conditions are VFR with high clouds. Overnight into Tuesday morning, around 11Z through 19Z, LIFR low clouds and fog are expected to develop in the Umpqua Valley. Patches of LIFR are also possible in the Rogue Valley, including the vicinities of Grants Pass and Medford, around sunrise (15Z through 18Z). && .MARINE...Updated 800 AM PST Monday, November 2, 2026...Long period west-northwest swell builds into tonight with steep seas in the outer waters. Shorter period southwest swell will then also build tonight into Tuesday with seas also becoming high and steep in the inner waters Tuesday through Tuesday evening. Conditions briefly improve on Wednesday. An active pattern resumes Wednesday night with building seas, including another long period west-northwest swell. Seas may become high and steep again on Thursday with the long period swell dominated seas forecast to reach a peak on Friday night at around 13 to 17 feet at 15 to 17 seconds. An active weather pattern will likely continue during the weekend into next week. && .BEACH HAZARDS...Updated 1100 AM PST Monday, November 2, 2026... Long period WNW swell will continue building into the area into this evening. Originating from near the western Aleutian Islands, these high-energy waves will have the ability to run much farther up the beaches and shorelines than normal and will likely produce dangerous sneaker waves. The swell will build to around 8 to 11 feet at 15 to 17 seconds. The sneaker wave risk will also be enhanced during the incoming high tide early this evening. The risk of sneaker waves will lessen later tonight as wave periods become shorter. && .PREV DISCUSSION... /Issued 349 AM PST Mon Nov 2 2026/ KEY MESSAGES... * Cooler weather and some chances of rain will arrive in northern California Tuesday with lower chances of rain in southern Oregon. * A weakening cold front will push into the coast Wednesday night. * Temperatures trend higher by Saturday. DISCUSSION... High clouds are currently moving over the forecast area ahead of the next short wave. We`ll see mostly cloudy skies this afternoon with temperatures right around the climatological normals for this time of year. Otherwise, not a lot happening through the day weather wise. The bigger change will come on Tuesday when the aforementioned short wave moves into northern California. It`s not looking very wet, although the PoP forecast does increase to about 30 to 40% over northern California with 10 to 20% chances here in southern Oregon. Pretty low impact weather continues now through Tuesday. High pressure will likely build in Wednesday afternoon in the wake of this short wave and temperatures will likely move a bit higher. Valley fog could form in a few valleys by Wednesday morning if there is enough surface moisture and dewpoints are high enough. By Wednesday night, models are suggesting a cold front and quick moving shortwave will swing into the Oregon coastline. The probability of precipitation increases to 40 to 60% along the coast with probabilities dropping off significantly farther to the south and east. Again, this is just a little rain with only a few hundreths along the coast. Finally, it looks like yet another deeper wave will be moving into the state of Washington, although the trough axis is not deep and just skids over Oregon. However, the cold front associated with this trough will approach the Oregon coast and bring low chances of precipitation around the Sunday time frame. Again, this isn`t a wetting rain, just enough to push the PoP forecast slightly higher. Overall, the weather pattern is exceptionally active, although most of the moisture is missing us to the north. The weather impacts will remain low and the biggest impacts will be the morning valley fog in some of our valleys. Lastly, the second week of November 8th to the 15 is looking wetter for our area based on the ensemble forecasts. There are few members still staying very dry for this week, although most are trending wetter with heavier precipitation. && .MFR WATCHES/WARNINGS/ADVISORIES...

039 FXUS66 KEKA 022135 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 135 PM PST Mon Nov 2 2026 .KEY MESSAGES... * Another round of light to locally moderate rain likely Tuesday. * Warmer temperatures for the end of the week and through the weekend. * Stronger storms with heavy rain possible starting around November 10th. && .SYNOPSIS...Light to moderate rainfall quickly moves through Tuesday. Conditions will then remain mostly dry apart from low chances for additional light rain or showers through the week and weekend for the North Coast. There continues to be indications a stretch of stronger Pacific storms capable of heavy rainfall and strong winds will begin near the 10th. && .DISCUSSION...The radar is already showing some light showers drifting toward the coast Monday afternoon. The showers are moving off of an approaching area of low pressure, which will continue generally towards southern Mendocinco. An associated surface low will initially have some stronger southerly winds on approach, but the low will be quickly weakening. Some gusty south winds are still likely, mainly over the ridges Monday night through late Tuesday morning. Rainfall will generally be light with this feature, particularly north of the King Range where downsloping winds will enhance the drying rain shadow. Of note, there will be instability around the low, bringing a chance for thunderstorms along the Mendocino coast and perhaps into Lake County. This convective activity will bring oportunity for locally high rainfall amounts in the described locations. Some weak fronts will bring some chances for light rainfall for mainly the Far North Coast through the week and weekend, but chances for over 0.1 inch of rain is only up to 35% for Del Norte county. High pressure will also be building in, allowing for warmer temperatures late week and through the weekend. Attention remains focused on the extended forecast when models and ensemble clusters are coming into closer agreement on a shift to a more active weather pattern. The threat start after the 9th, likely near of after the 10th. For that period, there is a 40 to 50% chance of exceeding two inches of rain over a two day period, and a 30 to 40% chance of exceeding three inches, respectively. Cluster analysis shows 50% of the members with over 2 inches in a 24 hour period. The possible atmospheric river storm system would be capable of strong southerly winds as well. JJW && .AVIATION...18Z UPDATE...Prefrontal conditions are expected through the day today with light, variable winds with a slight south to southeast component. Overcast clouds over 15k ft are present as a weak marine layer exists along the coast. Large breaking waves are increasing the exposure of coastal terminals to hazy, misty conditions down to MVFR status. Tonight, winds will turn more southerly for all areas as a cold front approaches NW CA. Expect weak rainshowers and possible gusty breezes near storms with downbursts possible. Winds near terminals by terrain could be turbulent as well. MVFR is expected through tomorrow morning between 12Z and 18Z. DS && .MARINE...An approaching cold front will impact the area over the next 24 hours. Southerly winds increase ahead of the front up to moderate breezes. A narrow area north of Cape Mendocino will likely have localized stronger winds up to fresh breezes. As this front approaches, winds continue to increase overnight into the morning. A brief period of near-gale gusts is possible from around 3AM to 6AM or so for all waters as the frontal boundary passes overhead. A pre- existing long period, NW swell is being recorded with waves of 9- 12ft at 18-20sec. This swell is expected to build through the day. Short period seas will also build as winds increase. This NW swell and the Southerly winds waves will cause a chaotic sea state. A small craft advisory has been issued as a result for the outer waters. Winds weaken slightly after the frontal passage, yet the NW swells are likely to continue through the week. DS && .BEACH HAZARDS...A very long period northwest swell is peaking Monday afternoon, but the size and energy will be very slow to subside. This continues to bring an extreme threat for sneaker waves through the evening as winds remain light and other wave groups remain limited. A Beach Hazard Statement is in effect through this evening for this sneaker wave threat. Sneaker waves are relatively large, unexpected waves with long period between large sets. Up to 30 minutes may pass between waves. Large, unexpected waves can sweep across the beach without warning, sweeping people into the sea from rocks, jetties, and beaches. Avoid jetties, steep beaches, and stay much farther back from the ocean! && .EKA WATCHES/WARNINGS/ADVISORIES... CA... Beach Hazards Statement until 10 PM PST this evening for CAZ101-103-104-109.

Updated at 1234 AM PST Mon Nov 2 2026 - Hazardous beach conditions through Tuesday evening and again Thursday through Saturday - Seasonal to slightly below seasonal temperatures through Thursday - Light rain for Tuesday except interior Central Coast && .UPDATE... Issued at 945 AM PST Mon Nov 2 2026 Below normal temperatures continue today with highs peaking in the mid to upper 60s. Rain remains on track to return tonight with the highest totals (0.50-0.70") across the North Bay coastal mountains. Showers pick up overnight and continue into Tuesday morning so expect wet roads along the coast and across the North Bay during the morning commute. There is a low potential for thunderstorms as the main rain band moves onshore tomorrow morning for the coastal North Bay. && .SHORT TERM... Issued at 1229 AM PST Mon Nov 2 2026 (Today and tonight) The system that brought precip over the weekend is now carving its way through the Four Corners region. In its wake upper level ridging is currently building over the CA. As such, expect warmer and drier conditions to kick off the work week. Speaking of the weekend rain, residual low level moisture may lead to some patchy fog, but widespread fog impacts are looking less likely this morning. High clouds associated with the next rain maker are spilling over the ridge, which is limiting radiational cooling potential. Temperatures this afternoon will be a few degrees warmer than Sunday and in the 60s to lower 70s. The dry weather will be short-lived as the next rain maker will make is presence known after midnight tonight. The ridge weakens and moves eastward. Behind the ridge is another upper level low. This feature will bring precip back to the region. Rain chances initially develop over the North Bay late tonight. && .LONG TERM... Issued at 1229 AM PST Mon Nov 2 2026 (Tuesday through Sunday) Will likely be a wet commute Tuesday morning as the associated surface low begins to move closer to the coast. Precip chances will spread S and E through the day, but loose some steam over the interior Central Coast. In addition to precip, instability increase over the northern coastal waters during the afternoon. Thunderstorms have been added to the forecast. Will leave them out of the forecast over land at this time, but some hi-res models suggest instability does briefly drift into Sonoma county during the afternoon. Thunder may need to be added on the next forecast update. Precip chances linger into early Tuesday before drier weather returns by Wednesday. Rainfall amounts will be greatest over the North Bay 0.10-0.50", Bay Area 0.01-0.25", Central Coast little to no accum. Wednesday kicks off a warming and drying trend that will last into next weekend with quasi-zonal flow transitioning to ridging aloft. Temperature rebound will be impressive too as highs reach the 70s to lower 80s next weekend. Looking out into fantasy land the Pacific stays active with additional rain chance on the horizon. Next rain chance return around Nov 10-11. && .AVIATION... (18Z TAFS) Issued at 1023 AM PST Mon Nov 2 2026 VFR conditions prevail as high clouds blanket the majority of the region this morning. These conditions will continue through the rest of today, with a pattern change occuring by Tuesday morning. An upper level low will cut across northern California brining rain to the Bay Area and perhaps into the northern area Central Coast region. The best chances look to be over North Bay and around SF Bay, with chances decreasing as you go inland. Started bringing -RA into the North Bay around 15Z, though some models show a 20% chance of it starting around 12Z for KSTS and areas north and west of there. Rain chances continue to spread to the southeast through the morning with showers being possible for the afternoon. We continue to keep an eye out at the thunderstorm chance. Probabilities over Sonoma County range from 0-20% favoring the west side of the region. Opted to not add any thunder to KSTS for the time being, but if thunder were to happen the best time frame would be from 18Z-22Z based on the latest guidance. Expect MVFR cigs with rain, though lower cig and vis are possible with stronger bands or cells of rain. Vicinity of SFO...High clouds, VFR conditions, and drainage winds are on tap for today. This evening winds back and gradually take on a southerly component ahead of the next weather system. Rain chances move in mid to late morning, with showers lingering into the afternoon. Winds begin to pick up as the rain arrives, with 10-15kt winds expected for Tuesday afternoon. SFO Bridge Approach...Similar to SFO. Monterey Bay Terminals...Mainly VFR conditions should prevail today with southeasterly flow at MRY and southwesterly winds at SNS. Moderate to high confidence of lower clouds overnight at MRY. High confidence of diurnal wind patterns through the TAF period. There is low confidence for rain early tomorrow morning, but it can`t be ruled out completely. && .MARINE... (Today through Saturday) Issued at 945 AM PST Mon Nov 2 2026 Rough seas will build into the outer waters tonight through Wednesday morning, bringing hazardous conditions for small craft. Gentle to moderate northwesterly breezes will increase and back tonight to become moderate to fresh southwesterly breezes ahead of an approaching cold front. Rain moves in Tuesday with this system, bringing with it a 15-20% chance of thunderstorms north of Pigeon Point. Moderate to fresh northerly breezes and moderate to rough seas will prevail Wednesday through Friday. && .BEACHES... Issued at 1229 AM PST Mon Nov 2 2026 Hazardous beach conditions will be present at Pacific Coast beaches Monday and Tuesday as long period (15-19 second) northwesterly swell will bring an increased risk for sneaker waves and strong rip currents.

Drier air moving will result in conditions being seasonal and mostly dry through Wednesday. Mountain snow showers and rain showers return mid to late week as two systems move through. && .DISCUSSION... Monday through Wednesday: High pressure has moved into the region bringing increased potential for fog and low stratus for the Columbia Basin and Spokane area Monday morning. Once the low clouds and fog dissipate late Monday morning, the INW will be left with slowly increasing high clouds in the afternoon. Temperatures will be near normal in the upper 40s to mid 50s. A shortwave trough moves near the northern California coast Tuesday morning, PWATs increase to 120-160% of normal across central and eastern Washington, bringing a small chance of sprinkles Tuesday morning. Weak high pressure stays in place through Tuesday night into Wednesday leading to dry conditions, but changes arrive Wednesday night. Thursday and Friday: A pair of systems will move through the region early Thursday and Friday, bringing periods of high mountain snow and very light valley rain. The best chance to get snow down to the mountain passes is Thursday night in the Cascades but it is not a guarantee. Snow levels are forecasted to be in the 4000-5000 foot range overnight Thursday. Thursday night into Friday is working with more impressive PWATs around 150-200% which brings a higher chance of rain making it into the valleys. The cold front passage Friday will bring breezy southwest winds gusting around 20-30 mph across the Columbia Basin, Palouse, and Spokane/Cda metro. From 4 PM Thursday to 4 PM Friday there is a 10% chance of 4 inches or more of snow at Stevens Pass and a 30% chance at Washington Pass. Saturday through Monday: There is generally good agreement of ridging returning behind this pair of systems into the weekend but not all the ensemble clusters are dry. A deep surface low will form in the Gulf of Alaska, drawing in moisture from subtropical origins. There is about a 50/50 split in the global ensembles that brings the longwave trough closer to the Pacific northwest which would favor rain and high mountain snow in the east slopes of the Cascades, northeast WA, and north ID. Southeast Alaska and British Columbia coastlines are most favored to receive rain and high mountain snow from this, but any eastward track of the longwave and the shortwave responsible for the deepening surface low will bring the moisture plume more towards the Pacific NW. /DB && .AVIATION... 18Z TAFS: Fog and stratus is slowly dissipating across much of northeast Washington and North Idaho. Fog and stratus could continue to bring brief MVFR conditions for KGEG/KSFF/KCOE /KLWS/KPUW through 21Z. Widespread improvements back to VFR expected by the afternoon. Widespread high level clouds will increase this afternoon from the west as a shortwave trough approaches the Pacific Northwest. This may reduce the fog and stratus development Monday night into Tuesday morning, but the NBM is carrying a 20-30% chance for IFR/LIFR conditions at KGEG/KSFF/KCOE/KLWS.

GOES-18 water vapor imagery shows an amplified upper-level ridge extending from California northeast through the Canadian Rockies. Upstream in the Pacific, a low-pressure system is developing in the vicinity of 39N, 142W. Nighttime microphysics imagery reveals mostly clear skies across the forecast area, albeit with low stratus and/or fog in portions of the eastern Columbia River Gorge, lower Columbia Basin, Blue Mountains, and cold mountain basins. At the surface, most valley/basin locations are nearly saturated at around 90-100% RH, and additional fog formation remains a concern for early morning. Have held off on any headlines due to the patchy nature, but will continue to monitor the situation. The aforementioned area of low pressure is expected (90% confidence) to develop into a closed low by Tuesday, eventually moving inland over southern Oregon or northern California by late Tuesday. Ensemble guidance suggests the low will be too far south to produce significant precipitation for our forecast area, and mostly dry conditions (PoPs of 20% or less) are forecast to continue until late Wednesday into Thursday when ensemble guidance highlights the arrival of a shortwave trough. Clusters of ensemble solutions continue to indicate significant spread in how much precipitation will accompany the shortwave; roughly one-third of members place noteworthy precipitation across the forecast area, while the remainder keep precipitation confined to the Cascade crest. By Friday, ensemble clusters are showing medium potential (~65%) of wet weather for the Washington Cascades, with significantly lower chances (~30%) for wet weather east of the Cascades. Ensemble guidance is trending towards mostly dry solutions (75-85%) by Saturday with an upper-level ridge overhead and precipitation displaced to the northwest of our forecast area. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... KDLS is buried in stratus with 700 ft ceilings this morning and the LAMP guidance in addition to REFS sounding profiles suggests these ceilings breaking out by 19 or 20z.

857 FXUS65 KREV 022002 AFDREV Area Forecast Discussion National Weather Service Reno NV 1202 PM PST Mon Nov 2 2026 .KEY MESSAGES... * A quick-moving low pressure system will bring gusty winds and increased chances for light rain/mountain snow showers on Tuesday. * Dry and mild weather prevails after Tuesday with temperatures trending warmer through the week. && .DISCUSSION... Today, an upper-level ridge is building over the region, sandwiched between two troughs. This pattern will lead to dry conditions and warmer daytime high temperatures. Nevada valleys and Sierra communities are expected to see highs in the mid 50s, roughly 5-10 degrees warmer than yesterday. Winds will remain light for most areas this afternoon and evening. Cloud coverage is already starting to increase this afternoon across the region, which will help moderate overnight cooling. Overnight lows will be 5-10 degrees warmer in the Sierra and western Nevada compared to the previous night, generally in the mid 20s for the Sierra and mid 30s for western Nevada valleys. Tomorrow, a low pressure system will move across northern California and into northern Nevada by tomorrow night. This system will usher in gusty winds and a chance for light rain and mountain snow showers. Latest model guidance such as the NAM (in it`s last full day of operation today) shows Sierra ridgetop winds increasing significantly, gusting 60-80 mph out of the south- southwest. These strong winds may mix down into eastern Sierra valleys and along the Sierra Front, with surface gusts up to 25-35 mph, potentially reaching 50 mph in wind-prone areas. Precipitation chances will increase through the day on Tuesday. Light showers will move into the Sierra and NE California around 11 AM-12 PM PST, reaching the Sierra Front by 3-4 PM, and the Nevada Basin and Range by 5 PM, before exiting the region by 8-9 PM. PoP values range from 60-80% in NE California and the Tahoe region, with lower chances (~20% or less) elsewhere. Accumulations are expected to be light, generally a trace to 0.15 inches, with higher amounts at the Sierra crest. The NBM shows a 50-60% chance of 1+ inch of new snow at the Sierra crest from Tahoe southward through Mono County, which could lead to minor travel impacts along Sierra passes. Snow levels will generally be around 6000-7500 feet, increasing to the higher end in the afternoon. Wednesday, the upper low will depart, and a flattened upper ridge will begin to build over the region. This will result in a return to dry conditions across the entire forecast area. Temperatures will remain mild, with a slight warming trend beginning. Highs are forecast to be in the low 50s in the Sierra and upper 50s in western Nevada, warming to the low 60s in the Sierra and upper 60s in western Nevada valleys by Saturday. These dry conditions and mild temperatures will continue through this weekend, with light winds. -Justin && .AVIATION... VFR conditions are expected for most area TAF sites today. Relatively light winds are expected with high cloud coverage increasing through the day. This cloud cover, along with the potential for stronger winds aloft mixing down to the surface overnight, may inhibit fog reformation near KTRK later tonight. Increased winds and rain/mountain snow shower chances are expected in the region on Tuesday, with Sierra ridgetops gusting up to around 60-70 kts causing potential mountain wave turbulence and LLWS along and east of the Sierra. Timing of the precipitation will be from 22Z-03Z tomorrow afternoon. Snow levels will be around 6000-7500 ft tomorrow, so snow accumulation for Sierra terminals is unlikely. -078/Justin && .REV Watches/Warnings/Advisories... NV...None. CA...None. && $$

723 FXUS66 KSTO 021958 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 1158 AM PST Mon Nov 2 2026 .KEY MESSAGES... - Drier and near seasonal normal temperatures today - Quick moving system brings shower/isolated thunderstorm chances and breezy winds Tuesday - Drying and warming trend Wednesday through the weekend, with near to slightly above normal heading toward the weekend && .DISCUSSION... Today: High pressure has begun to shift eastward today, promoting dry and near seasonal normals temperatures. Partly to mostly cloudy skies are observed across the area as high-level clouds stream around the northern periphery of the ridge. Afternoon temperatures are forecast to be in the 60s for the Valleys, mid-50s to mid-60s for the foothills and mid-40s to mid-60s for the mountains. Tonight-Tuesday: A deepening upper-level trough and associated cold front will approach the region tonight into Tuesday. A frontal boundary will bring breezy southerly winds late tonight through Tuesday. Gusts around 20 to 35 mph are likely, with the strongest winds along the Sierra. Locally strongest winds up to 45 mph are possible over the higher terrain. A quick progressive cold front will bring rain and high elevation snow (above 6500 feet) showers on Tuesday. Expect light to locally moderate rain showers with this system. Rainfall total amounts range from a few hundredths to a quarter of an inch, with locally higher amounts in the Coast Range. Snow level will remain generally above 6,500 feet, but with light moisture moving across the area. That said, up to 2 inches of snowfall is expected for the Northern Sierra Nevada and southern Cascades, including Lassen National Park. There remains a 10% or less chance of thunderstorm. Lingering showers are expected to dissipate Tuesday night as high pressure build rapidly into the region in the wake of the trough. With clearing skies, areas of valley fog are expected to develop into Wednesday. Wednesday-Weekend: A period of north to east winds is expected to develop on Wednesday, with the breezier north winds through the Valley/Delta west of Interstate 5 in the afternoon transitioning to breezy downslope easterlies along the Sierra overnight into Thursday. A weak shortwave is expected to traverse the area Wednesday night into Thursday, but mostly dry weather and seasonable high temperatures is expected. Ensemble guidance suggest drier and warmer weather conditions across northern interior California late this week and through the weekend as the 500 mb ridge build across the region. && .AVIATION... VFR conditions are generally expected to prevail at TAF sites through the next 24 hours; however, ceilings will begin lowering around 14z Tuesday, reaching as low as 3,500 ft by 21z Tuesday. Ceilings should remain above MVFR criteria though. Winds generally southerly and less than 12 kts across the Valley TAF sites. Gusts up to 35 kts over higher elevations in the mountains from 06z Tuesday to 00z Wednesday. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$

137 FXUS65 KMSO 021917 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 1217 PM MST Mon Nov 2 2026 .DISCUSSION... KEY MESSAGES: - Mild and quiet weather expected through Wednesday, though morning low clouds or valley fog is possible. - Two weak systems bring showers Thursday and Friday with light dusting of snow above 5,000 feet, and westerly breezes. - Mild and dry conditions return for the weekend, with morning fog remaining possible. High pressure building over the region will lead to stagnant conditions and trapped surface moisture, creating a favorable setup for locally dense valley fog tonight into Tuesday morning, and again on Wednesday morning. Motorists should exercise caution, as visibility will vary significantly over short distances on local roadways. Fog will generally dissipate by each afternoon, allowing daytime temperatures to warm near or slightly above seasonal averages, peaking in the 40s to low 50s. A pair of weak weather systems will pass through the region on Thursday and Friday, bringing a return to active weather but minimal impacts. Light showers will primarily be focused across northwest Montana, though overall precipitation amounts will remain limited. Snow levels will hover near 5,000 feet. In addition to the showers, expect an uptick in afternoon breezes, particularly on Friday. High pressure returns this weekend, bringing a stretch of mostly dry conditions, mild afternoons, and localized morning valley fog. By Sunday and Monday, remnant moisture from an atmospheric river impacting the Pacific Northwest coast will spill inland, bringing renewed chances for light showers to northwest Montana. Looking further ahead to Nov 11-14 suggests a broader pattern shift. Atmospheric rivers initially aimed at the Pacific Northwest coast are forecast to sag southward and push inland. This transition would increase the likelihood of more widespread precipitation across our region, including the potential for accumulating mountain snowfall. Confidence in this pattern setup is low to moderate, but it is certainly something we will keep an eye on. && .AVIATION... Mostly VFR weather conditions will prevail this afternoon with light terrain-driven winds at the surface and some lower broken clouds hugging terrain creating localized obscurations especially near the Continental Divide. Localized morning fog or low stratus is very likely to develop overnight into Tuesday morning. Any low ceilings or fog is anticipated to lift or burn off by mid- day. Areas of wildfire smoke from prescribed burning may enhance the obscurations due to smoke and fog in the overnight and early morning hours. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None.

Near to slightly above normal temperatures through the week. - Dry today, then a slight chance of showers late Tuesday through Friday. && .SHORT TERM /Through Wednesday Night/... Quiet conditions will persist through the short term period with no significant weather expected across southeast Oregon and southwest Idaho. Upper level ridging centered over the Pacific Northwest will provide dry weather and mostly clear skies tonight into Tuesday morning. Patchy valley fog or low stratus remains possible during the late night and early morning hours, mainly within sheltered mountain basins and river valleys. A compact upper level low tracks eastward across the Great Basin on Tuesday. The primary impact from this system will be an increase in mid and high level cloud cover. There looks to be enough moisture and weak instability for a slight chance (15 to 20 percent) of light rain showers along the Idaho/Nevada border Tuesday afternoon and evening. Elsewhere, dry conditions will prevail with light winds. The low will exit into the central Rockies on Wednesday while weak upper ridging rebuilds from the west. This will result in clearing skies and continued dry weather through Wednesday night. Temperatures will remain near to slightly above seasonal normals through the period, with daytime highs generally in the mid 50s to lower 60s in the valleys and upper 40s to lower 50s across the higher terrain. Lows will dip into the upper 20s and 30s for most locations. && .LONG TERM /Thursday through Monday/... A pair of weak upper level troughs will move through on Thursday and Friday, bringing a 10-30% chance of showers to northern areas. QPF totals are expected to stay under 0.10" for both events combined. Snow levels will range from 5500-7000 ft MSL, so some of the higher peaks will see a light dusting. Temperatures will be near normal with light winds. An upper level ridge will build in over the weekend, with temperatures warming to 5-10 degrees above normal by Sunday. Another upper level trough will approach the Pacific Northwest early next week, ushering in low chances of showers by Monday night. Temperatures will be similarly warmer than normal on Monday with breezier conditions Sunday and Monday as the system approaches. && .AVIATION /18Z Monday through Tuesday/...
