153 FXUS66 KSEW 060446 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 846 PM PST Thu Nov 5 2026 .UPDATE... No changes made in the inherited forecast. We`re currently in a lull before the next system offshore arrives later this evening into early Friday morning with widespread rain and gusty winds. Wind advisories are still on track to go into effect for the coast, Whidbey & San Juan Islands along with the Northern Interior late overnight. Wind gusts upwards of 50 mph are possible during this time. Overnight lows are forecast to bottom out into the 40s. The previous discussion remains below along with an updated aviation section. && .SYNOPSIS... A strong frontal system will bring gusty winds and additional rainfall to western Washington tonight and Friday. A warm front will boost temperatures as it moves northwards into the area Saturday. A follow-up cold front Saturday night into Sunday will bring another round of rain and gusty winds. The weather pattern remains active into at least the first half of next week. && .SHORT TERM /TONIGHT THROUGH SATURDAY NIGHT/... Current satellite imagery shows typical autumn cloudy skies over W WA in advance of the incoming frontal system. Radar is starting to clearly show the leading edge of this system over the outer coastal waters. A weak shortwave ridge will hold that system at bay briefly, keeping conditions dry for much of W WA this afternoon and into the early evening before rain moves in tonight. Gusty winds will accompany the incoming front with particular concern for higher wind speeds along the coast and the NW Interior /including the islands as well as portions of western Whatcom and Skagit counties/...where speeds could get as high as 20-30 mph with gusts to 50 mph. Models have remained consistent with these speeds and as such, inherited Wind Advisory for the aforementioned areas remains on track. As this system mainly impacts the area through the day Friday, this is when the bulk of the rainfall is expected with amounts ranging one-half to three-quarters of an inch on the high end...mainly expected over the higher terrain and along the coast...to one tenth to one quarter of an inch most remaining lowland locations. Snow levels will rise throughout the event, starting the day off at around 5000-6000 ft and lifting to around 9000 in the afternoon. As such, not much of a concern for high elevation snowfall at this time. The front pushes out of the area very late Friday night, allowing for another weak, short-lived shortwave ridge to enter the area. This feature will not be terribly effective at dispelling clouds nor lingering post-frontal showers, but does provide a relative lull in activity for much of Saturday before the next frontal system comes knocking on the coastline come Saturday night. Another round of strong winds will accompany this front as it moves through during the overnight hours, with wind impacts being felt over much of the CWA. While the more wind prone locations along the coast, the islands and the NW interior will likely see headline conditions, it is entirely possible that other locations along the Sound may see speeds high enough to qualify. It is a little too far out to make decisions on headlines just yet, but situation is being monitored. Even though the short term will be active, temperatures are expected to remain mild with daytime highs still a few degrees above seasonal normals. Saturday will actually see a boost in temperatures with daytime highs that day getting into the 60s for most lowland locations. Overnight clouds will keep lows from sinking too much, mostly ranging from the mid 40s to around 50 for the entire short term period. 18 && .LONG TERM /SUNDAY THROUGH THURSDAY/... Winds ease quickly Sunday with most breezy conditions wrapping up by mid-morning. Frontal passage throughout the day will drag its feet a bit, but a follow-up shortwave ridge should begin to impact the area Sunday night into Monday. This break in the action continues until Monday afternoon, when the next frontal system will begin to enter the area. By this point, snow levels will have fallen to around 4000- 5000 ft, but are quick to rebound late Monday to above 6000 ft. The frontal passage late Monday will extend into Tuesday with another potential break possible Wednesday as upper level ridging builds over the Rockies. Models fall into disagreement here as the westward extent of the ridge is a point of contention. The operational deterministic models show the split well, with the ECMWF keeping the ridge east enough where rain could get at least as far east as the Olympic Peninsula while the GFS shows the ridge west enough to keep any systems off the coast. Ensembles show a wide array of solutions, however the mean does trend slightly drier...leaning more toward the ECMWF and perhaps even dragging precip slightly further east. The NBM falls in line with this latter thinking and is a good starting point for the forecast this far out. Neither daytime highs nor overnight lows stray too much from the temperature pattern established during the short term. 18 && .AVIATION... Generally VFR across western Washington terminals this evening, with areas of MVFR ceilings along the Pacific Coast as a frontal system with rain approaches the coast. An OVC100 ceiling across the region will gradually lower tonight as a frontal system pushes through the area, trending towards low end VFR to MVFR, with potential for lower IFR conditions in heavier rain. Rain will start moving in along the coast around 06Z and fill into the interior terminals after 10Z tonight. Additionally, gusty winds will develop tonight into Friday, mainly along the coast and north of PAE, where sustained wind speeds of 15-25 kt with gusts toward 30-40 kt are possible after 09z Fri. Southeasterly winds will also become breezy elsewhere, with gusts up to 20-30 kt through Friday afternoon. KSEA...VFR this evening with mid to high clouds gradually lowering early Friday morning closer to low end VFR/MVFR as a frontal system moves inland. Rain will spread over the terminal in the early morning Friday, likely bringing MVFR conditions after 09z Fri. SE winds around 5-10 kt, with gusts up to 20 kt possible during the day Friday. 29/15 && .MARINE... An active weather patter across area waters will continue into next week as a series of frontal systems cross the region. These frontal systems will bring both the combination of seas and winds. The next frontal system will impact the waters tonight into Friday, bringing elevated seas around 14-20 ft and gale force winds across the coastal waters and portions of the interior waters. Additionally, there is a slight chance (15-20%) for storm force winds at times for the coastal waters, East Strait, and Northern Inland Waters. A stronger system will arrive this weekend for elevated seas and possible widespread gale force winds. Models are hinting at a 30-40% chance for storm force gusts over the coastal waters and Strait on Saturday afternoon and a 20% chance for for Admiralty Inlet, Northern Inland Waters, and Puget Sound. Additionally, models continue to be consistent with the chances for seas above 20 feet by early Sunday morning. Brief high pressure will build over the waters Sunday night into early Monday. Multiple systems will move over the waters next week, with the continued potential for additional headlines. A period of strong afternoon ebbs are expected for Grays Harbor Bar starting Friday, which could coincide with with a rough to severe bar at times. 29 && .HYDROLOGY... River flooding is not expected through the next seven days. However, a series of increasingly wet weather systems will bring rain (and high mountain snow) to the region, especially from Friday onward. While current forecasts are not expected to cause flooding, this will begin to saturate soils and raise base flows that could bring a concern with subsequent storms systems into next week. && .SEW WATCHES/WARNINGS/ADVISORIES...

978 FXUS66 KPQR 052254 AFDPQR Area Forecast Discussion National Weather Service Portland OR 254 PM PST Thu Nov 5 2026 .SYNOPSIS...Mostly dry weather today before wetter and more active weather returns Friday. Additional chances for rain return late Saturday afternoon into Sunday, and Monday through the middle of next week. South winds become breezy later Saturday afternoon and evening. && .DISCUSSION...through Wednesday...Clouds are clearing enough for the sun to peek through this afternoon as weak, transient ridging moves over NW OR and SW WA today. Expect calm and dry weather to continue through tonight, though mostly cloudy skies will return by Friday morning as the next weather system approaches the region. Rainy season has officially arrived for the Pacific NW. The next week will be characterized by repeated weather systems producing multiple rounds of rain and occasionally breezy winds. At this point, precipitation amounts associated with each weather system will be on the lighter side, leading to limited widespread flooding concerns. The next weather system will bring rain to the coast Friday morning, spreading inland Friday afternoon through the evening. The surface low associated with this system will move farther north into British Columbia, so rain will mainly be limited to locations northwest of a line stretching from Newport to Corvallis to southern Hood River County. Highest rain amounts will be along the north OR and south WA coast, ranging from 0.25-0.75 inch of rain with anywhere from a few hundredths to 0.25 inch for inland areas. A brief break between weather systems will bring dry conditions everywhere except the far north OR and south WA coast during the day Saturday with daytime temperatures rising into the low to mid 60s along the coast and inland valleys. However, expect skies to remain mostly cloudy as a stronger low pressure system quickly moves through the eastern Pacific towards the coast. This system will speed through the area Saturday night with most rain falling before Sunday morning, though post-frontal scattered showers will linger into the day. This rain will be more widespread, though still on the lighter side with 0.2-0.5 inch for inland valleys and 0.3-0.75 inch for the coast and terrain. Breezy winds will accompany the frontal passage with this weather system, especially along the coast and over terrain. There`s a 20-40% chance of wind gusts of 55 mph for the beaches and headlands along the coast and 5-20% chance for coastal communities off of the beach. This probability increases to 35-55% for the high Cascades. Inland valleys are more likely to see peak gusts up to 25-35 mph with a 40-70% chance of wind gusts over 30 mph. Winds will increase along the coast in the afternoon, spreading inland by 8-11 pm, and decreasing by 5-8 am. Winds of this magnitude along the coast could cause some downed trees and power outages, though inland impacts would mainly be some downed tree limbs, especially as many trees still have leaves. Ensemble guidance is in good agreement that another round of brief, dry weather returns Sunday afternoon into Monday morning before yet another weather system impacts the PacNW. High uncertainty remains with the evolution of this system, in terms of both location and intensity. Both the GEPS and EPS indicate this system could sustain IVT values between 250-500 kg/ms for a much longer duration than previous weather systems, generally around 72 hours, with a 55-70% chance that IVT values exceed 500 kg/ms for at least 48 hours of that period. This would support higher rain accumulations than previous weather systems, though NBM probabilities for even 1 inch of rain in 48 hours ending Wednesday morning is around 50-70% for the coast and 25-60% for the Cascades and inland valleys. Probabilities for 2 inches in the same 48 hour period decrease quite a bit. These probabilities are likely on the lower side due to the significant uncertainty on where in the PacNW the main plume of moisture will fall. Widespread flooding impacts are not expected at this time with only 1-2 inches in 48-72 hours, though antecedent rainfall from earlier weather systems could lead to more saturated soils and increased areal flooding in low lying or flood prone areas. Keep an eye out on the forecast for any changes. -03 && .AVIATION...Through 00Z Saturday...This afternoon generally VFR conditions are in place across the region as a weak ridge of high pressure moves overhead accompanied by some high clouds. Headed through the evening and overnight hours, this trend of generally VFR conditions should hold. However, we`ll have to keep an eye on patchy fog formation mainly in the Tualatin Valley, and in central/southern Willamette Valley, after 09-11z through 18z Friday. Probabilities for sub-MVFR/IFR conditions are around 15-30% for most inland sites, highest in the aforementioned areas. The approaching weather system also brings chances for light rain to KAST in the morning before those chances shift inland in the afternoon. Expect winds along the coast to increase out of the south on Friday as well with gusts around 20-30 knots during the afternoon. -99 KPDX AND APPROACHES...VFR conditions likely persist through the evening hours. We`ll have to keep an eye on fog/low stratus formation late overnight but the overall set-up is more marginal due to high cloud cover compared to the last several days. The probability for IFR conditions are only 15-20% locally between 09-15z. Winds gain a southerly component of Friday but stay fairly light overall. -99 && .MARINE...A very active and winter-like weather pattern will take hold across the coast waters headed through the weekend into next week. Expect south winds increase late tonight through Friday as our next frontal system pushes towards the waters. Confidence is high wind gusts exceed 34 knots around and north of Cape Falcon Friday morning through the afternoon so a Gale Warning is in effect during this time period. Steep and hazardous seas will also be possible later Friday as significant wave heights likely build to 14 to 18 ft prompting a Hazardous Seas Warning for the coast waters south of Cape Falcon. Headed through Friday evening/night winds ease briefly, however, an even stronger front is expected to quickly approach the area late Saturday morning into the afternoon hours, bringing more widespread chances for Gales (85-95%) across our entire coastal waters - winds peak Saturday evening. It now appears as winds peak right along the frontal boundary, there is a decent chance (30-55%) for a period of Storm Force winds across the waters as well, with the highest probabilities Cape Falcon northward. Another westerly swell is expected to build seas into the mid to upper teens, with around a 25-45% chance of wave heights exceeding 20 ft. The active weather pattern likely continues into early next week as additional weather systems parade into the Pacific Northwest facilitating a similar array of impacts. -99/DH && .PQR WATCHES/WARNINGS/ADVISORIES...

964 FXUS66 KMFR 052346 AFDMFR Area Forecast Discussion National Weather Service Medford OR 346 PM PST Thu Nov 5 2026 .Updated AVIATION Discussion... && .AVIATION...VFR conditions prevail across the area this afternoon with some high level cirrus streaming overhead. With drying of the boundary layer today, VFR conditions should prevail for most locations south of the Rogue-Umpua Divide and east of the Cascades. Can`t completely rule out some patchy fog in the more narrow valleys west of the Cascades, but with drying today and continued high level cloud cover, fog development should be less extensive. Along the coast and into the Umpqua Divide, where moisture has been more consistent, patchy LIFR conditions are possible tonight, including at North Bend and Roseburg. Any lower conditions that develop, should clear to VFR by late Friday morning. && .PREV DISCUSSION... /Issued 241 PM PST Thu Nov 5 2026/ KEY MESSAGES... * The influence of a Pacific ridge will bring a warming trend on Friday and Saturday. Daytime highs on Saturday look to be 5 to 15 degrees above normal, with the warmest temperatures in northern California valleys. * A cold front arrives Saturday evening into Sunday morning. This front looks to bring rainfall to Oregon counties west of the Cascades as well as gusty winds to the coast and over terrain. Winds and rainfall ease by Sunday afternoon. * A progressive pattern will bring chances for activity through next week, although confidence in the details remains slight. Overall, there are no signals for broad hazardous conditions. DISCUSSION...An upper ridge over Pacific high pressure is being nudged over the area by active weather passing to the north, bringing stable conditions and a warming trend to most areas. By Saturday, daytime highs could be 5 to 15 degrees above seasonal norms. Coastal cities will generally stay in the low 60s, with Coos Bay possibly getting a little warmer. West side valleys look to be in the low to mid 70s while east side valleys and basins are forecast to be in the mid to high 60s. A cold front arrives late Saturday, bringing gusty winds and rainfall to coastal areas. Activity moves inland over Oregon`s west side areas early Sunday morning, with most rainfall expected over coastal terrain and the Cascades around Crater and Diamond lakes. Amounts are unimpactful, with those elevated areas forecast to get 0.25 to 0.5 inches of rain and the areas in between getting less. The Cascades and east side terrain will see periods of gusty winds into Sunday morning. Winds and precipitation decrease by the afternoon, with cooler daytime highs from the cold air mass behind the front. Broad agreement in the pattern for next week is starting to come into focus, but substantial uncertainty remains. Generally, southwest flow between a Pacific trough and a continental ridge will keep temperatures near or just above seasonal levels. Guidance shows three main chances for activity. A front approaches the area on Monday evening into early Tuesday morning, with the ECMWF showing a period of west side rainfall while the GFS expects that front to be drawn north and have no effect. After some mild warming on Tuesday and Wednesday, energy deepens the Pacific trough and pushes it eastward towards the end of next week. There`s some agreement that rainfall from the leading edge of this trough would be minimal and limited to coastal areas, as the eastward movement would push it against the continental ridge and drain that energy. Some ensemble members show this trough picking up more moisture and bringing higher rainfall amounts to Brookings and North Bend. A few models show the ridge having minimal influence and the energy bringing end-of-week rainfall as it pushes inland. In the case where the ridge does weaken the Thursday-Friday trough, the trough is also able to push the ridge east. From here, ensemble members show low pressure systems bringing some kind of activity to the area just beyond the forecast period but with varying timing and positions. Looking at the big picture, these various features all approach from the west or southwest. With this approach, winter impacts should be limited. Current NBM guidance keeps snow levels in the 6000-8000 foot range. Brookings and North Bend have the most agreement on seeing rainfall with these features, while inland expectations vary and chances decrease to the east. Depending on its orientation, the Thursday-Friday trough may bring gusty southerly winds. But overall, nothing in guidance indicates highly hazardous conditions for the area at this point. -TAD MARINE...Updated 215 PM PST Thursday, November 5, 2026...Seas will remain high and steep as westerly swell around 10 to 13 feet at 13 to 17 seconds moves through the waters tonight into Friday, creating conditions hazardous to small craft. Low pressure will move through the NE Pacific and onshore into British Columbia Saturday into Sunday. South winds will increase in our waters Saturday, probably remaining just below gale force Saturday afternoon and evening. Expect small craft conditions to persist with a combination of swell and steep wind waves. A stretch of high to very high seas is expected late Saturday night and Sunday after the associated cold front moves onshore. Winds will diminish during this time frame, but seas will increase to a peak of 15-20 ft with the period increasing from 13 to 16 seconds Sunday evening. Swells will gradually subside Monday. -Spilde BEACH HAZARDS...Long period westerly swells moving through the coastal waters will have enough energy to produce an elevated risk of sneaker waves on SW Oregon beaches (Douglas, Coos and Curry counties) tonight into Friday. Initially today, swells are running 10-13 feet at 13 seconds, but periods lengthen to 17 seconds late this evening and will remain elevated through the day Friday. Please use caution at the beaches and avoid rocks, logs and jetties. Sneaker waves can run up significantly farther on beaches than normal, including over rocks and jetties. These waves can knock people off their feet and sweep them into the ocean. The waves can also move logs or other objects which could crush or trap anyone caught underneath. In addition, a high to very high swell is expected to arrive at the coast late Saturday night into Sunday. Breaker heights in the surf zone could reach 22-25 feet. Be on the lookout for potential high surf advisories. && .MFR WATCHES/WARNINGS/ADVISORIES... OR...Beach Hazards Statement from 10 PM PST this evening through Friday evening for ORZ021-022. CA...None.

690 FXUS66 KEKA 052316 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 316 PM PST Thu Nov 5 2026 .KEY MESSAGES... * Warmer temperatures with additional chances for light rain this weekend. * Stronger storm systems with heavy rain possible starting around or after November 10th. * Minor to possibly near moderate coastal flooding is likely around Humboldt Bay from November 7th to 10th. && .SYNOPSIS...Conditions will trend warmer and drier through the week and into the weekend. Another front will clip the area late Saturday into early Sunday, bringing chances for light rain for isolated areas. The weather pattern continues to look to trend more active mid to late next week. && .DISCUSSION...A series of strong NE Pacific cyclones will form and impact regions north of CA in the Pacific Northwest and BC. These storm systems sent a weak front over far NW California Tuesday evening and another one is expected Saturday evening into Sunday. There is a higher chance of rain for the weekend system, with 30-50% chance for over a half inch of rain for N Humboldt to Del Norte. Though the much stronger winds will be farther north over Oregon, some recent model runs have trended the trough farther south, so the wind threat will need to be watched for the Del Norte area. Currently probabilities for gusts over 35 mph are low for the coast and ridges of Del Norte. The NE Pacific troughs that pass well to the north will amplify ridging over the west. Temperatures will trend warmer in response. Ridging will peak Saturday when highs in some of the interior valleys are forecast to reach the upper 70s to 80 degrees, and this will be 10 to up to 20 degrees above average for the time of year. The longer term forecast still holds a signal for a more active pattern, with ensembles showing the potential for more impactful storms capable of heavy rainfall and strong winds. Non linear error growth through the farther extended timeframe leads to over- amplification of the large Pacific storm systems in the global models. This is evident in the growing variability in solutions, with half the clusters depicting 1-2 inches of rainfall and the other 50% dry through the 11th through 12th of November timeframe with slightly better agreement later in the 12-13th. Strong southerly winds would also be probable with an atmospheric river type of weather system. JJW && .AVIATION...18Z UPDATE...VFR conditions are expected through the day along the North Coast with inland valleys experiencing areas of IFR fog which is expected to burn off by midday. The current offshore winds are expected to shift northerly through the day before calming this evening and switching southerly by dawn tomorrow. Surface fog is possible, yet unlikely tomorrow as the influence of an incoming cold front to the north of the area will likely disrupt any cold pooling at the surface. Inland afternoon winds will be strongest along ridges as a relatively stable atmosphere remains through the day, yet afternoon NNW breezes are forecasted to reach the valley floors. DS && .MARINE...The sea state will be dominated by the influence of an incoming cold front to the north of the area through the end of the week. Northerly winds build today as the interior heat creates a relatively week surface pressure gradient. That said, a small craft advisory is still issued for the coastal waters due to steep large NW waves entering the waters mixing with the locally generated short period seas. The NW Swell of 8-10ft @ 13sec will continue through the end of the week before being reinforced with another similar NW swell Saturday morning. As this swell arrives, expect southerly winds to build with the strongest flow in the far northern waters. Near the coastline, offshore winds are expected Saturday morning as well for the North Coast. Light north winds will develop Sunday before southerlies reform before the start of next week. DS && .BEACH HAZARDS...An eastward propagating, strong Aleutian low will deliver a second long period WNW swell. The swell will arrive late Thursday with periods up to 20 seconds. The swell will peak at around 11 to 13 ft at 17 seconds Friday, bringing a low to moderate risk for sneaker waves. Sneaker waves are a unique hazard, with up to 30 minutes between waves. Large, unexpected waves can sweep across the beach without warning, sweeping people into the sea from rocks, jetties, and beaches. These sneaker waves can also move large objects such as logs, crushing anyone caught underneath. Even ankle to knee deep water can knock you down and drag you out when a sneaker wave hits. Pay attention and stay above the high water line and any wet sand to stay safe. If the ground is wet, waves have surged there recently. Stay safe and never turn your back on the ocean! && .COASTAL FLOODING...The positive tidal anomaly remains increased again, continuing bring tides higher than predicted. The increased southerly winds brought tides around 1.5 ft higher than forecast Wednesday at the North Spit gauge. Tides are officially forecast to reach 7.4 to 7.5 feet at North Spit on the 7th through 10th of November. The current range of tidal anomalies would bring tides up to and over the advisory level of 8.8 ft, and minor coastal flooding around Humboldt Bay. There will likely be periods of stronger southerly winds through those days, bringing higher confidence to at least minor coastal flooding, and perhaps near moderate. && .EKA WATCHES/WARNINGS/ADVISORIES...

651 FXUS66 KMTR 060508 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 908 PM PST Thu Nov 5 2026 ...New AVIATION, MARINE... .KEY MESSAGES... Updated at 1200 PM PST Thu Nov 5 2026 - Slightly warmer and dry weather through early next week - Coastal flooding due to high tides through Friday (11/13) - Hazardous beach conditions through Monday && .UPDATE... Issued at 754 PM PST Thu Nov 5 2026 A few high to mid-level clouds continue to stream overhead as high pressure builds over the region. The SFO-WMC pressure gradient strengthened to -6.3 mb from -3.1 mb this time yesterday. This will support another overnight push of offshore flow across the higher terrain. Despite this, there is a slight chance (20%) for fog development in the North Bay interior valleys due to radiational cooling before sunrise. Navarrete && .SHORT TERM... Issued at 1200 PM PST Thu Nov 5 2026 (This evening through Friday night) Temperatures will be on a gradual warming trend through the remainder of the week as high pressure builds in from the Eastern Pacific. As such, afternoon temperatures will be up to 2-8 deg F above seasonal averages today in the major population centers. High clouds will be streaming in from the northwest throughout the afternoon and evening hours, having little effect on temperatures. Not seeing much in the way of fog development tonight, as weak to moderate offshore flow persists across the higher terrain of the Bay Area and Central Coast. However, cannot rule out a few pockets of fog in the North Bay valleys early Friday morning and lingering until the sun rises before quickly mixing out. Once again, high clouds are forecast to stream in from the northwest on Friday morning and then clearing out by mid-to-late afternoon. As such, daytime high temperatures on Friday look to be a few degrees warmer than today. && .LONG TERM... Issued at 1200 PM PST Thu Nov 5 2026 (Saturday through next Wednesday) Weak ridging or zonal flow will persist across the region through early next week, leading to slightly above normal temperatures. This will be both overnight minimums and afternoon maximums. A shallow marine layer, generally less than 1,000 feet, is forecast to return Saturday night into Sunday morning ahead of an approaching frontal system set to move into northern California. Confidence in wet weather conditions have stayed the same if not lessened slightly heading into the middle of next week and beyond. Again, the ECMWF ensemble mean shows greater than 2" of rain at SFO between Wednesday the 11th and Wednesday the 18th. While that is about normal for the interior month, it looks to be spread out in time. However, given the lack of confidence looking out this far in time, be sure to check back for the latest forecast information. && .AVIATION... (06Z TAFS) Issued at 907 PM PST Thu Nov 5 2026 Currently VFR. Moderate to high confidence in VFR and diurnal winds prevailing through the TAF period. Warmer and drier conditions should preclude fog/stratus development; however, there is a low probability for radiational fog/stratus to develop. If it develops, it`ll likely be between 08Z and 20Z with the best chances 14Z to 18Z. Vicinity of SFO...Currently VFR with westerly flow. Moderate to high confidence in VFR and diurnal winds prevailing through the TAF period. SFO Bridge Approach...If radiational fog/stratus develops, it`ll likely initiate along the San Mateo Bridge Approach. Monterey Bay Terminals...VFR conditions are expected to continue though the TAF period. Drainage winds will persist overnight before veering mid morning returning the area to sea breeze conditions. && .MARINE... (Tonight through next Wednesday) Issued at 907 PM PST Thu Nov 5 2026 Rough, ten foot seas will result in hazardous conditions for small craft across the outer waters through Saturday. Very rough seas will build into the outer waters Sunday into Monday with moderate to rough seas across the inner waters. Moderate to fresh northerly breezes will prevail across the inner and outer waters with bays remaining more sheltered. && .BEACHES... Issued at 1200 PM PST Thu Nov 5 2026 Beach Hazards Statement: Hazardous beach conditions will be present at Pacific Coast beaches through Monday as long period (14-18 second) westerly/northwesterly swell will bring an increased risk for sneaker waves and strong rip currents. Breaking waves of 12 to 16 feet are expected at exposed beaches. Spring tides will also increase the currents and bring higher tides than normal. Waves can sweep across the shoreline without warning, pulling people into the sea from beaches, jetties, and rocks. Stay off of jetties, piers, rocks, and other waterside infrastructure. Remain out of the water to avoid hazardous surf and never turn your back on the ocean! Coastal Flood Advisory: A combination of high astronomical tides and thermal expansion from warmer than normal water will result in tidal flooding concerns across Bayshore locations in the San Francisco, San Pablo, and Monterey Bays. At the San Francisco tide gauge, high tide is expected 1.4 ft above normal (7.2 ft MLLW) at 9:08 AM Friday 11/6, 1.6 ft above normal (7.4 ft MLLW) at 9:38 AM Saturday 11/7, 1.6 ft above normal (7.4 ft MLLW) at 10:06 AM Sunday 11/8, 1.6 ft above normal (7.4 ft MLLW) at 10:35 AM Monday 11/9, 1.5 ft above normal (7.3 ft MLLW) at 11:04 AM Tuesday 11/10, 1.4 ft above normal (7.2 ft MLLW) at 11:35 AM Wednesday 11/11, 1.4 ft above normal (7.2 ft MLLW) at 12:10 PM Thursday 11/12, 1.2 ft above normal (7.0 ft MLLW) at 12:49 PM Friday 11/13. These predictions include up to 1.5 ft of surge that will enhance the astronomical tide and flooding threat. High tide varies up to 90 minutes earlier or later along the Pacific Coast and through the San Francisco Bay, respectively. In addition, long-period swell will create hazardous conditions along the Pacific coast beaches with an increased risk of sneaker waves and rip currents. These Spring Tides are due to a new moon on Monday, which is much lower in the sky this time of year compared to a full moon. In 2 weeks, the astronomical tides will be about 0.8` higher than this round, and the total water level could be more than a foot higher if we get SW winds and/or lower pressure. This combination would bring the total water level near the 1% annual exceedance probability (2.85` above normal), or a 1 in 100 year event. Something to keep an eye on for the week of Thanksgiving.

532 FXUS66 KOTX 060038 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 438 PM PST Thu Nov 5 2026 .KEY MESSAGES... - Periodic chances for light rain and mountain snow Friday into early next week. - Gusty winds out of the southwest Saturday night into Sunday. && .SYNOPSIS... Unsettled conditions continue into the weekend and early next week a series of systems bringing periods of rain, mountain snow, and gusty winds. && .DISCUSSION... Thursday night into Friday: Strong zonal flow sets up over the Inland Northwest through this period as a warm front lifts into the area. Friday looks mostly cloudy with a combination of patchy low stratus and widespread mid and high level clouds. Precipitation chances move into the Cascades Friday morning, then expand across the western Columbia Basin by afternoon. The warm front continues to lift north into Friday night, shifting precipitation chances over Northeast WA and North ID. Snow levels start out around 4-4.5 kft Friday morning, then rise to 7-9 kft by Friday evening as the warm, moist airmass takes over. Consequently, precipitation in the Cascades will begin as valley rain and mountain snow in the morning and transition to all rain over the course of the day. Saturday: Saturday will feature a brief break from cloud cover and precipitation while we are in between systems. Highs will be quite warm Saturday, ranging from the mid 50s to mid 60s. If you`re hoping to make any outdoor plans this weekend, Saturday is the day to do it. Saturday night through Wednesday: A progressive pattern persists with a series of systems impacting the Inland Northwest into early next week. The strongest of these systems arrives Saturday night into Sunday, bringing gusty winds in addition to renewed precipitation chances. Precipitation chances with this system increase for the Cascades Saturday night and spread toward the eastern third of WA and the ID Panhandle by Sunday morning. Strong west-southwest flow will result in a pronounced rain shadow over much of the Columbia Basin and North-Central WA. Snow levels will start out around 7.5 kft Saturday night, but will lower to around 4.5 kft by Sunday morning, bringing potential for light snow over Washington Pass. Currently the NBM gives Washington Pass a 60 percent chance of receiving at least 2 inches of snow by Sunday morning. For 3 inches or more, chances drop to 10 percent. As far as winds go, wind speeds and gusts will start to ramp up overnight Saturday and are forecast to peak Sunday morning and early afternoon. The strongest winds will be across the Columbia Basin, up the Okanogan Valley, and over the Waterville Plateau. Expect sustained wind speeds of 15-25 mph and gusts up to 40 mph for the aforementioned areas. /Fewkes && .AVIATION... 00Z TAFS: The stratus has mostly moved out of PUW, LWS, MWH, and EAT, with all four sites being at VFR. GEG, SFF, and COE remain at MVFR as stratus is still clearing to the northwest on visible satellite. Clouds look to be moving inland across the state, which, alongside saturated profiles, will keep ceilings for GEG, SFF, and COE at MVFR through tomorrow morning. Since elevated winds 10kts and above will be moving in, ceilings are expected to improve to VFR by 16-18Z. Since PUW, LWS, and EAT all improved to VFR, those conditions are expected to prevail. For MWH, there are increased probabilities that visibilities may drop in the early hours of the morning, but they are also supposed to clear out by later morning, around 18-20Z. FORECAST CONFIDENCE AND/OR ALTERNATE: Moderate confidence in GEG, SFF, and COE seeing MVFR conditions through tonight and tomorrow morning. Moderate confidence in VFR prevailing at PUW, LWS, and EAT.

614 FXUS66 KPDT 052303 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 303 PM PST Thu Nov 5 2026 .KEY MESSAGES... - Rain chances return Friday afternoon and late Saturday. - Breezy winds late Saturday through Sunday morning. - Mountain precipitation persist through early part of week. && .DISCUSSION... Current radar and visible satellite imagery shows mostly clear skies under dry conditions. This is in response to an upper level ridge building in from the southwest on the heels of the departing shortwave that brought light rain to the area early this morning. The axis of the ridge will continue to shift east and elongate, shifting flow aloft from the northwest to more from the southwest into Friday. As this slowly shifts, a shortwave passes through Central British Columbia to allow light showers to develop across the Washington Cascades and Columbia Basin. Rain amounts are expected to stay light across the Columbia Basin, likely 0.02" or less. The NBM advertises a 10-40% chance of measurable rainfall (0.01" or less) across the Columbia Basin, with 10% being over the Tri-Cities and 40% over the Yakima and Kittitas Valley. Showers will primarily be focused across the Washington Cascades, with up to 0.25" across higher terrain. Due to the more southwesterly flow, snow levels will hover around 8000 feet. A more substantial upper level system will approach the southern British Columbia coast on Saturday, before moving onshore overnight into Sunday. This will bring additional showers across the Cascades late Saturday before extending across the Blue Mountains Sunday morning. Rain amounts of 0.20-0.40" are expected across the east slopes of the Cascades late Saturday, with closer to a wetting rain (0.10") above 4000 feet. The incoming shortwave will be more oriented north-to-south, which will incur more of a rain shadow effect across the Columbia Basin, likely keeping most areas dry. This also aligns with the NBM which shows a 5-15% chance of measurable rainfall expected across lower elevations of the Columbia Basin, increasing to a 40-60% along the Blue Mountain foothills. The weekend system will also attribute to breezy conditions across central and eastern Oregon Saturday afternoon through Sunday morning, with highest winds expected across the Grande Ronde Valley. The GFS highlights a pressure gradient of 3-4mb between Baker and Meacham, which may lead to advisory-level winds. Sustained south winds of 25-35 mph with gusts of around 45 mph are expected. The NBM suggests a 60-80% chance of sustained winds of 30 mph or greater, with a 50-70% chance of gusts reaching 45 mph or greater. This provides rather high confidence in a Wind Advisory being necessary across the Grande Ronde Valley Saturday evening through Sunday morning. A weak ridge of high pressure moves in Sunday afternoon, drying conditions briefly before the next shortwave approaches the coast on Monday morning. This again brings more mountain showers along the Cascade and Blue Mountains Monday, ahead of additional showers through the beginning part of the week due to a strengthening upper level trough offshore. The trough will enhance southwest flow aloft, keeping light showers in the forecast across the Mountains through Wednesday. Guidance suggests the best chance for widespread showers that extends across the Columbia Basin will be Tuesday, as advertised by 69% of ensemble members. 75 && .AVIATION /00Z TAFS THROUGH 00Z SATURDAY/... VFR conditions persist through the period with dry conditions embedded with light winds.

724 FXUS65 KREV 052213 AFDREV Area Forecast Discussion National Weather Service Reno NV 213 PM PST Thu Nov 5 2026 .KEY MESSAGES... * Dry and mild weather with periods of breezy winds are expected through early next week. * A wetter and windier pattern remains favored to arrive around and after Veteran`s Day. && .DISCUSSION... Dry and mild weather is expected through early next week as high pressure keeps the storm track directed north of the region. Daytime highs today and Friday will be in the upper 50s and 60s -- on par for early November -- before warming into the 60s to near 70F this weekend. Hazy skies are likely each morning with stout inversions in place, especially near any prescribed burns. A couple of trough passages to the north will encourage a return of breezy afternoon winds this weekend into early next week, but winds aren`t expected to be atypically strong. Otherwise, this weekend is shaping up to be a favorable one to enjoy outdoor activities so be sure to take advantage! Ensembles remain keen on pattern change around the middle of next week as the storm track dips southward, but are wavering on the onset of a more unsettled weather pattern. The potential for gusty winds and showers begin to increase in earnest after Veteran`s Day, which is about a day later than what prior guidance suggested. Nevertheless, the signal for wetter and windier weather for the end of next week into the following weekend has been consistent, so worth keeping in mind if you have any travel or outdoor activities planned during that timeframe. -Salas && .AVIATION... VFR conditions are expected today for area TAF sites with skies clearing up a bit through the day. Low confidence on a return of FZFG to the Northern Sierra valleys tonight due to drier weather, but will monitor conditions and amend TAFs if needed.

471 FXUS66 KSTO 051951 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 1151 AM PST Thu Nov 5 2026 .KEY MESSAGES... - Dry weather, above normal temperatures, and periodically breezy winds through the weekend and into next week - Slight chance for light rain showers in Shasta County Sunday into next week - Potential shift toward active weather pattern mid to late next week && .DISCUSSION... Today-Saturday: A period of northwesterly flow aloft continues into today in the wake of downstream troughing with a brief period of ridging aloft the building in friday into the early weekend ahead. The resulting appreciable weather at the surface will remain seasonable to warm with periodically breezy north to east winds Today into Saturday AM. Strongest north winds gusting 15 to 25 mph are still anticipated along and west of the Interstate 5 corridor this afternoon with additional northerly gusts up to 15 mph across a similar area Friday afternoon. Downslope east-northeast winds along the Sierra will follow similar diurnal trends with strongest gusts 25 to 35 mph during the overnight and early morning hours through Saturday AM. High temperatures begin to reach the lower 70s for much of the Valley with 50s to 60s elsewhere in the mountains this afternoon. As ridging aloft amplifies across Interior NorCal alongside reinforcing surface high pressure Friday afternoon into Saturday, high temperatures look to trend a bit warmer then early November normals with widespread Valley and foothills high temperatures in the low to mid 70s and widespread mountain high temperatures firmly into the 60s. With the transition from northwesterly flow aloft to ridging aloft, winds are expected to decrease throughout the day on Saturday, remaining generally light area wide across the rest of the weekend. Sunday-Next Week: As the ridge axis shifts eastward a broad area of west-stouhwest flow and weak troughing aloft looks to build in Sunday into next week. Despite this upper level shift, high heights aloft look to persist at least into the middle of next week. This flow pattern should usher in a gradual return toward light onshore flow alongside continued warmer than normal high temperatures. While available moisture early to mid next week will limit overall precipitation potential area wide, any ejecting shortwaves have the potential to introduce at least light shower chances for portions of Shasta County into next week. Ensemble guidance still generally indicates potential for a shift toward an active weather pattern, including chances for heavy rain and heavy mountain snow, around the mid to late next week period, although recent trends are beginning to favor the late week solution. A high degree of uncertainty still accompanies the forecast relative to this potential shift. The anticipated southward progression of deep troughing over the Gulf of Alaska toward the California coast remains the largest piece of uncertainty at this time. Persistent ridging and high heights aloft across much of interior California have so far staved off this robust system. Given the deep fetch of available moisture offshore and general ensemble trends for the aforementioned trough to break through and dig southward at some point next week, the CPC 8-14 Day Outlook (Nov. 12-18) continues to highlight a moderate risk for heavy rain and heavy mountain snow, as well as a slight chance for high winds. Be sure to stay up to date with the latest forecast information and check back for updates as we get closer. && .AVIATION... VFR conditions prevail this afternoon and will continue to do so through the early evening. North winds will continue to gust 15 to 25 kts until 00Z Friday, especially in the northern Sacramento Valley. As winds weaken after 00z Friday, another period of MVFR/IFR conditions in BR/FG will be possible throughout the Valley into Friday morning with best chances after 10z Friday and generally west of Interstate 5. && .STO WATCHES/WARNINGS/ADVISORIES...

024 FXUS65 KMSO 052112 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 212 PM MST Thu Nov 5 2026 .DISCUSSION... KEY MESSAGES: - Mild weather pattern under southwest flow into next week. - Periods of valley fog and stratus, especially in western Montana. - Weather system to bring shower activity, minor precipitation, and high elevation snow on Sunday. A weak weather system has been pushing eastward across the Northern Rockies this afternoon. Shower activity has been trending downward in the last few hours, with area rain gauges showing the majority of measurable precipitation along the Idaho/Montana border, with a trace to 0.10 inches reported. Valley stratus continues to impact many valley areas in western Montana, including Missoula and Kalispell. The stratus deck may temporarily improve for a handful of locations into this evening, but overnight conditions will once again become favorable for valley stratus and fog, especially in northwest Montana where warm lake temperatures over Flathead Lake are helping to saturate the boundary layer. Model guidance is strong agreement for high pressure to rebuild across the region Friday into Saturday. This pattern once again appears favorable for patchy valley fog or low stratus clouds, especially in western Montana. This potential brings higher uncertainty into the high temperature forecast for Saturday, with temperatures potentially being to warm in the forecast shall stratus clouds and fog become widespread as they have in the last few days. The next weather system will track through the Northwest, moving along the Canadian border Sunday. A trough passage will breakdown the ridge, with shower activity bringing minor precipitation and high elevation (above 5,500 feet) snow along the Idaho/Montana border and in Northwest Montana. Wind will also increase, with valley gusts up to 25 mph as higher elevations experience gusts of 30-40 mph. Ensemble cluster analysis points towards high pressure rebuilding once again to start next week. This pattern once again points towards areas of valley fog and stratus. && .AVIATION...A weak cold front is moving through the region today which is causing scattered light showers and some westerly winds helping break up the low stratus and fog in the valleys north central Idaho and parts of western Montana. The shower activity will cause obscured mountain tops and passes as snow levels are hovering around 4000 ft MSL this afternoon. The shower activity and winds will diminish during the evening. The improvement in the ceilings will be fairly shortlived as clearer skies tonight will allow inversions to redevelop. KMSO and KGPI will mainly be affected by a low stratus deck, but KHRF has the potential of experience low stratus by Friday. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None. ID...None. && $$

Issued 208 PM MST THU NOV 5 2026 Quiet and dry weather is expected across southeast Oregon and southwest Idaho through Saturday night. An upper level ridge builds into the Intermountain West behind departing weak northwest flow, allowing heights and thickness values to steadily rise. Dry air will maintain mostly clear to partly cloudy skies with light surface winds, though some overnight valley inversions and patchy early morning fog remain possible in sheltered basins. High temperatures will trend upward each afternoon, climbing several degrees above normal for early November. Lows will remain seasonal to slightly mild. No significant weather hazards or travel impacts are anticipated through the period. && .LONG TERM /Sunday through Thursday/... Issued 208 PM MST THU NOV 5 2026 A weak shortwave and accompanying cold front will track across the Pacific Northwest on Sunday. Moisture and dynamics remain quite limited with this boundary, confining a slight chance of light showers mainly to northern Baker County and the West Central Mountains of Idaho. The remainder of southwest Idaho and southeast Oregon will stay dry with little more than passing mid and high clouds. Behind this system, the synoptic pattern amplifies substantially heading into early next week. A deep upper level trough establishes itself off the Pacific Coast, pumping strong south- southwesterly flow and anomalous warmth northward into the Great Basin and northern Intermountain region. Temperatures will climb rapidly from Monday onward. By Wednesday, high temperatures are projected to peak in the mid to upper 60s for lower elevation valleys, which is roughly 15 degrees above seasonal normals. Several locations, including the Treasure Valley, could approach or exceed daily record highs. Dry and tranquil conditions will persist across the forecast area through mid-week under this strong ridge before model guidance begins to hint at unsettled weather approaching late in the week as the offshore trough edges eastward. && .AVIATION /00Z Friday through Saturday/...
