042 FXUS66 KSEW 082305 AFDSEW Area Forecast Discussion National Weather Service Seattle WA 305 PM PST Sun Nov 8 2026 .SYNOPSIS... A brief break in the weather this afternoon with some showers around. Multiple systems look to cross over the area through Tuesday, bringing rounds of widespread lowland rain, gusty winds, and high elevation mountain snow. Active weather continues through the end of the week with additional systems passing into the area. && .SHORT TERM /TONIGHT THROUGH TUESDAY/... Recent radar imagery shows some scattered showers across the Northern Interior and Cascades. Expect this trend to continue throughout the evening hours, with a slight chance (10-20%) of thunderstorms north of Everett. An upper level ridge will move through the area tonight, with drying overnight. Another frontal system will start to move over the area by Monday morning, with rain reaching the coast by the afternoon. Rain will slowly move through the interior by the late afternoon and early evening hours. Additionally, southerly winds will increase once again, with widespread gusts of 20 to 30 mph possible at times throughout much of the area (less strong than the previous days wind). Areas along the coast and Whidbey Island could see gusts up to 35 mph. High temperatures in the mid to upper 50s. Heading into Tuesday, a long fetch of moisture being aimed at Vancouver Island slightly moves down through western Washington. We`ll see another round of widespread rain, with a bulk of the QPF being aimed right at the coast and the Olympic Peninsula. Southerly winds will increase in the afternoon and be slightly stronger than Mondays, with widespread gusts of 35 to 45 mph along the coast, and areas Whidbey Island northward. Rain and wind will continue into Wednesday morning. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Upper level troughing continues Wednesday into Thursday for some scattered shower activity over the region, keeping conditions unsettled. Additionally, minor coastal flooding may be possible on Wednesday morning due to high astronomical tides, primarily along the shorelines of San Juans and Whatcom county. High temps warm up slightly on Wednesday, in the low 60s. Latest ensemble guidance shows an upper level low around BC that is funneling a plume of moisture towards BC and western Washington Friday into Saturday. At this time, looks like active weather will continue, with widespread rain and breezy winds into the weekend. We`ll continue to monitor this system as it gets closer. Mazurkiewicz && .AVIATION... Scattered showers will taper across the area into this evening for a brief break in between weather systems. Terminals are largely VFR and will remain so through tonight. Winds have remained breezy to 20 kt this afternoon, but will continue to ease over the next few hours, persisting at 5-10 kt through this evening. Winds will then become light and shift more easterly after 06Z. Despite high cloud cover streaming in overhead, a few patchy areas of fog may develop at the more fog-prone terminals across the southern Sound (like KOLM) overnight. Should fog develop, it may briefly bring a few hours of IFR to LIFR conditions to terminals on Monday morning. Another frontal system will move across the area on Monday, bringing another round of rain and breezy winds to the area terminals. Latest hi-res shows rain starting to move inland along the coast between 19-21Z, before spreading into the interior between 21-23Z. Conditions will likely drop down to MVFR as the rain pushes inland. Winds will pick up to 8-12 kt along the coastal terminals in the morning, before picking up across the interior terminals in the afternoon. Gusts to 25 kt will be possible as the system moves through. KSEA...VFR conditions will persist through Monday morning at the terminal. Southerly winds persisting at 8-12 kt with some gusts to 20 kt this afternoon will continue to ease through this evening. Winds will become light overnight, shifting to the east after 06Z. Another round of rain will move into the terminal Monday afternoon, likely between 21-23Z. There is a 40-50% chance of conditions dropping down to MVFR Monday afternoon as the rain moves in. Southerly winds will increase Monday afternoon as the system approaches, persisting at 8-12 kts, with gusts to 20 kt. 14 && .MARINE... High pressure building back over the area this evening will bring a brief period of calmer winds to the waters through late tonight. The next frontal system will move across the coastal waters on Monday, with winds starting to increase across the coastal waters again by early Monday morning and across the interior waters by late morning. Winds will peak in the afternoon, before easing Monday night. Gale warnings are in effect for the Coastal Waters and the Eastern Strait, where probabilities continue to highlight roughly a 60-80% chance of gusts reaching 34 kt. Elsewhere, southerly winds will be breezy, with winds gusting to small craft strength through the afternoon and early evening. There will be a brief lull in winds on Monday night, before another system moves into the region on Tuesday and brings a stronger round of southerlies to the area waters and likely another round of widespread headlines. The weather will remain active through the end of the week as additional frontal systems move through the waters. Seas between 19-24 ft this afternoon will gradually subside towards 10-12 ft on Monday before the next system brings seas back to the 16-18 ft range on Tuesday. Seas will largely remain above 13 ft through much of the week. The next best chance for seas to build to 20 ft will be by next weekend, with the GEFS highlighting a 30-40% chance of seas exceeding 20 ft off the Washington coast. 14 && .HYDROLOGY... River flooding is not expected the next seven days. Multiple weather systems moving through the area in the next week. While current precipitation forecasts are not expected to cause flooding, this will saturate soils and raise base flows. If the atmospheric river stalls over the area late next week into next weekend we might need to keep an eye on our old friend the Skokomish River. Felton && .SEW WATCHES/WARNINGS/ADVISORIES...

076 FXUS66 KPQR 090509 AAA AFDPQR Area Forecast Discussion...UPDATED National Weather Service Portland OR 909 PM PST Sun Nov 8 2026 Updated Aviation Discussion .SYNOPSIS...An active weather pattern will continue through much of the next week, producing periods of rain and wind, especially along the coast. Following a midweek lull, a more potent system could affect the region late in the week. && .DISCUSSION...Now through Saturday...The progressive pattern will continue to support repeated chances for rain through the next week. An upper-level shortwave exiting eastward will see lingering light rain showers this afternoon, before transient ridging supports a drying trend from this evening through early Monday. The next upper-level trough and surface cold front will track inland, bringing rain Monday afternoon before exiting eastward Monday evening. Rainfall totals on Monday are expected to be around 0.25 inches along the I-5 corridor and around 0.5 inches along the coast, Coast Range, and Cascades. Seasonable temperatures in the 50s also continue through this period. On Tuesday, upper-level ridging will begin amplify inland as another upper shortwave moves into the Pacific Northwest. This will act to limit rain to the coast, Coast Range, and inland areas north of US-20 early, then steadily displace rain chances to the north through Tuesday night. A rather sharp gradient in rainfall totals on Tuesday is expected from south to north, with little to no rain south of US-20, up to 0.25 inches from US-20 to the Columbia River, and 0.25-0.5 inches in southwest Washington, highest on the north shore of Willapa Bay. Heavier rain associated with this atmospheric river is expected over the Olympic Peninsula. Breezy south to southeast winds with gusts as highs as 25-35 mph can be expected along the coast north of Tillamook and over southwest Washington to the west of I-5 through Tuesday night as the front lifts northward. Upper-level ridging will reach its peak amplitude on Wednesday, supporting dry and unseasonably warm temperatures in the low to mid 60s with light offshore flow. Daily record high temperatures look to remain largely out of reach, however the record values of 64F at Portland (PDX) set in 1989 and 66F at Vancouver (VUO) set in 1904, 1907, and 1930 may be in jeopardy. There remains good consensus that upper ridging will shift inland while troughing returns to the Pacific Northwest from Friday into next weekend. Long-range ensembles support about a 70% chance for vapor transport to exceed 500 kg/(ms) at the leading edge of this trough on Friday somewhere along the Oregon coast as another potential atmospheric river affects the region. The chances for 2" of rain from Friday morning through Sunday morning are 15-30% along the I-5 corridor and 50-65% along the coast. Repeated rounds of rain and increasingly saturated soils could allow for greater runoff into area rivers, meaning at least isolated flooding cannot be ruled out. -36 && .AVIATION...Through 06Z Monday...Current observations show widespread VFR conditions. Conditions are expected to slowly CIGs begin to fall towards low-end VFR through 15Z-18Z Monday ahead of the next system. Southwesterly winds along the coast and variable winds inland around 3-6 kt through around 18Z Monday. The next system arrives Monday morning, returning rain showers to the coast and southern Valley around 16Z Monday, spreading northeastward into the rest of the Valley by 18Z Monday along with Coastal TAF sites. As the front moves in, conditions will trend towards MVFR/IFR along the coast starting around 18Z-20Z Monday, and around 21Z-23Z Monday for inland locations. Guidance suggests a 40-70% chance for MVFR CIGs across the region at any given hour between 18Z Mon-00Z Tue, with the highest chances along the coast. Southerly winds increase tomorrow after 18Z Monday with gusts up to 30 kt along the coast while winds generally remaining under 10 kt inland. However, could see some isolated gusts up to 20 kt for locations within the Central Willamette Valley and neat the mouth of the Columbia River Gorge from 18Z-23Z Monday. For far eastern Portland Metro terminals (KPDX/KTTD), winds trend more east/southeasterly, which could result in some LLWS for KTTD from 20Z-23Z Monday. KPDX AND APPROACHES...VFR conditions with mid to high clouds. Around 18Z Monday, conditions drop towards low-end VFR/MVFR as the next system approaches. 30-50% chance for MVFR CIGs at any given hour between 21Z Mon-02Z Tue. /42 && .MARINE...An active weather pattern will continue across the waters through the week. As of early Sunday afternoon, winds remain under 20 kt as we are in between storm systems. However, a steep, long period westerly swell continues to bring seas of 20-26 ft at 14-16 sec through this evening. Seas should gradually fall below 20 ft after 2200 Sunday, and below 17-18 ft after 0100-0400 Monday as the swell comes down. Seas fall as low as 10-13 ft on Monday before the next system arrives. Hazardous Seas Warnings remain in effect for all of the waters including the Columbia River Bar through 0400 Monday. Winds over the waters begin to ramp up early Monday morning as the next frontal system approaches the waters. High resolution model guidance suggests high confidence (>80% chance) for a return of breezy southerly winds with gale force wind gusts up to 35 kt at any given hour from 0900 to 1600 Saturday. This will result in more wind-driven seas. On Tuesday, another system will bring another round of gale force wind gusts, and an increasing westerly swell will build seas to 13-16 ft at 13-15 seconds. An active pattern continues through the rest of the week with additional rounds of gale force wind gusts. There`s a brief break on Thursday before conditions ramp up again at the end of the week. -10 && .BEACH HAZARDS...High Surf Warnings remain in effect through 10 PM this evening along the Oregon and Washington coasts as a steep, long period westerly swell between 20-26 ft at 14-16 ft continues to push into the coast. This will continue to result in large waves and dangerous surf conditions. Destructive waves may wash over beaches, jetties, and other structures unexpectedly. Extreme caution should be used if you plan to visit beaches today. The large wave runup will dislodge logs on area beaches and result in them rolling up and down area beaches, which have historically killed or seriously injured unsuspecting people, so there will be much more of a threat than just getting wet from a rogue wave. Given the momentum behind these large longer period waves, it`s not out of the question that we receive a report or two of damage to infrastructure along the coast. -10 && .PQR WATCHES/WARNINGS/ADVISORIES...

831 FXUS66 KMFR 082315 AFDMFR Area Forecast Discussion National Weather Service Medford OR 315 PM PST Sun Nov 8 2026 .KEY MESSAGES... * Moderate impact marine/beach weather involving hazardous seas and hazardous surf conditions through this evening * Inland, this is an overall low impact forecast through at least Thursday night * Light, higher terrain focused showers taper off this evening with another round of light to moderate rainfall expected Monday/Monday night * The southern end of a front brushes the coast north of Cape Blanco on Tuesday, otherwise dry weather with warmer afternoons (around a dozen degrees above normal) Tuesday through Thursday * A period of active weather is likely to start Friday or Saturday and continue into early next week && .DISCUSSION... Unusually high surf will persist at beaches this evening, though the very slightly higher peak of 28 to 33 foot breaker heights occurred around noon. The remnants of a front will dissipate overnight. Lingering low level moisture will produce a few isolated very light showers over the higher terrain this evening, and also areas of valley low clouds and fog late this evening into the morning. The warm frontal portion of an occluding front will move inland on Monday with west side focused light to locally moderate rain, and snow levels around 8000 feet. The higher rain rates are expected at the coast during the late morning and early afternoon, with precipitation tapering off Monday night into early Tuesday morning. High pressure, centered in the Great Basin, will build in Tuesday into Thursday with a strong warming and drying trend. Lows will be seasonably cold. Wednesday looks to be the warmest day, with highs in the 60s and 70s. But, each of the 3 days will have highs around a dozen degrees above normal. The 12Z suite of models is still having difficulty in timing the shift from a ridge dominated pattern with the approach of a broad upper low moving southeast from the Gulf of Alaska. The ECMWF is on the faster side of the cluster of solutions with moderate to heavy rain moving into the west side during Friday. Meantime, the GFS happens to be on the slow side with moderate to heavy rain holding off at the coast until Saturday and not making much inland progress until Saturday evening. Heavy rain associated with frontal passage may be limited to the coast, though around 10-15% of members extend it into inland portions of the west side. Very few of the ensemble members are faster than the ECMWF or slower than the GFS. For now, the NBM is handling the uncertainty appropriately with rain chances to the west of Lake and Modoc Counties during Friday and probabilities increasing thereafter through Saturday and Sunday. Snow levels are forecast to be around 7000 feet before falling to around 5000 to 5500 feet Sunday. && .AVIATION (18Z TAFs)... The remnants of a front will linger into this evening with mainly VFR, but also patchy MVFR and isolated light showers. Overnight, after 09Z, recent rainfall is likely to lead to IFR/MFR conditions for westside valleys including KRBG and KMFR. Meantime, light offshore flow may prevent low clouds from impacting the coast tonight. Lastly, there is some uncertainty for low clouds tonight impacting KLMT, but confidence was not high enough to include at this time even though some guidance is suggesting low level saturation. A warm front will arrive at the coast later Monday morning with light rain and areas of MVFR developing. && .MARINE...Updated 200 PM PST Sunday, November 8, 2026...High to very high long period westerly swell peaks this afternoon at 20-25 feet at 16 seconds, but continues through this evening resulting in warning level seas for all waters. Another front arrives on Monday which will bring gale gusts to the northern waters with overall steep to very steep seas. High and steep seas and advisory strength south winds are likely through the end of the week. && .BEACH HAZARDS...A High Surf Warning remains in effect this evening. A long period west swell produced peak breaker heights in the surf zone of 25-33 feet, and will remain nearly as high through this evening. Large breaking waves will create hazardous conditions along and within the surf zone, and could inundate beaches and low lying shorelines. Beach erosion is possible, and exposed infrastructure may be damaged. && .MFR WATCHES/WARNINGS/ADVISORIES... OR...High Surf Warning until 1 AM PST Monday for ORZ021-022. CA...None.

091 FXUS66 KEKA 082358 AFDEKA AREA FORECAST DISCUSSION National Weather Service Eureka CA 358 PM PST Sun Nov 8 2026 .KEY MESSAGES... * Light rain Monday afternoon in Del Norte and Humboldt counties. * Minor coastal flooding is likely around Humboldt Bay from Sunday through Tuesday. * Breaking waves of 20 to 25 feet are expected today and these may coincide with a very high tide generating significant wave run-up. * Stronger storm systems with more rain late in the week. && .SYNOPSIS...A series of cold fronts are expected to bring light rain in the northern areas of the CWA again on Monday. Mainly dry and unseasonably warm conditions are expected on Tuesday and Wednesday. Thursday may start to see some cooling, but still generally dry conditions. Friday and into the weekend may see some more significant rain. && .DISCUSSION...A cold front passed through early this morning, bringing light rain to Del Norte and Humboldt county with the highest rainfall near central Del Norte. Camp six RAWS reporting 0.74 inches since 7pm last night. Higher recordings of precipitation were in the inland mountain ranges of Del Norte. The exception would be Klamath areas of Turwar and Salt Creek with around 0.48 and 0.58 inches respectively, closer to the coast. Winds will veer southerly late tonight/early Mon Sunday night southerly winds and clouds are expected ahead of another frontal boundary. This is expected to be slightly stronger than the system early Sunday and rainfall is expected to make it slightly farther east and south. There is a 70 percent chance in Del Norte county of over a half inch of rain. This drops to only a 30 percent by Trinidad and quickly lower as goes farther south. A wetting rain is possible in northwestern Trinity county and possibly some of the higher terrain in western Trinity such as South Fork Ridge. Much of Mendocino and Lake counties are expected to remain dry as well as eastern Trinity county. This will generally keep temperatures a few degrees cooler than Sunday. Tuesday is expected to see some warming and dry once again as high pressure builds into the area. Many of the inland areas are expected to warm into the 70s again with upper 70s possible in the south. Wednesday may be even warmer in many areas. Locations in the shade such as the deeper valleys will remain cooler. Thursday an upper level trough approaches the area, but the models are still not in very good agreement on the prospect for rain. Two of the ensemble clusters show show light to moderate rain while the two others show no rain. This split generally continues on Friday, although the two wet clusters show heavier rain. Saturday all four of the clusters are starting to show rain, but there are still some pretty big differences in the amounts. So the potential continues for a pattern switch to a wetter pattern, but so far we aren`t really seeing anything that would increase our confidence in it actually happening. MKK/EYS && .AVIATION...Post front, winds have turned northerly and cloud cover initially broken to scattered is likely to return to overcast tonight as high resolution models show heavy cloud cover filling in ahead of the next frontal boundary, expected by 12z or so Monday morning. More immediately we have diminished visibility at the coastal terminals due to haze and mist, likely from the high surf and wave action off the Del Norte and Humboldt coast. Rain is expected Monday morning at KCEC and KACV. Expect overcast skies with gusty southerly winds as the front arrives by 16z. Ceilings will improve as the boundary lifts the cloud deck from 300ft/LIFR to 5000ft with reduced visibility as hydrometeors obscure. Possible LIFR until the early evening Monday. /EYS && .MARINE...Large WNW swell has arrived, quickly building in this afternoon. The swell is already around 18 to 20 ft, with a period of 15- 17 seconds. Buoys to the north are showing wave heights up to 23-24ft so there is the possibility of even larger surf and increased hazards in the area waters. There is still some uncertainty on the size of this swell and it is possible this will come in larger than expected. The swell will then ease late tonight through Monday. Southerly fresh breezes develop again Monday with another front. These are expected to diminish with gentle to moderate southerly breezes on Tuesday and early Wednesday. Wednesday afternoon southerly winds may briefly increase before diminishing again. && .BEACH HAZARDS...A large swell has arrived and could cause large breaking waves of 22 to 24 feet for west to northwest facing beaches through Monday morning. A High Surf Advisory remains in place for this threat. Extra caution is advised near beaches this weekend due to the increased swell activity. These waves are also expected to arrive at the same time as the high tide and this will allow waves to run farther up on the beach. && .COASTAL FLOODING...Water levels inside Humboldt Bay continue to run 1.2 to 1.3 feet over the astronomical tides. Southerly winds expected to return with the next front early Monday morning, ~12z or so and may increase these slightly with water levels inside Humboldt bay reaching 8.8 to 9.0 ft on Sunday. The large swell on top of this high water may impact some areas even inside Humboldt Bay. Outside of Humboldt Bay on the open coast, Crescent City and Arena Cove tide gauges are running 0.5 to 1.0 feet above astronomical tides. The southerly winds may increase this slightly too. These are expected to remain below flood advisory levels; however, the large breaking waves may briefly flood minor roads and parking lots that are exposed at high tide. MKK/EYS && .EKA WATCHES/WARNINGS/ADVISORIES... CA... High Surf Advisory until 10 PM PST this evening for CAZ101- 103-104-109. Coastal Flood Advisory from 10 AM to noon PST Monday for CAZ103.

035 FXUS66 KMTR 082340 AFDMTR Area Forecast Discussion National Weather Service San Francisco CA 340 PM PST Sun Nov 8 2026 ...New AVIATION, MARINE... .KEY MESSAGES... Updated at 1230 PM PST Sun Nov 8 2026 - Slightly warmer and dry weather through the midweek - Coastal flooding due to high tides through Friday - Hazardous beach conditions through Monday - Unsettled weather returns by late week and into the upcoming weekend && .SHORT TERM... Issued at 1230 PM PST Sun Nov 8 2026 (This evening through Monday night) High pressure remains the dominate weather pattern aloft leading to our warming trend, despite a weakening frontal boundary to our north. As such, temperatures will remain 5-10 deg F above early- November climatological norms. Meanwhile, high clouds continue to stream in from the west. Tonight and into Monday morning, there is the potential for low clouds and/or fog in the Bay Area, much of the Santa Clara Valley, East Bay Valleys, and North Bay Valleys. Similar to today, any fog that does develop will likely dissipate between 9 AM - 10 AM and give way to mostly sunny conditions by the afternoon. Temperatures Monday afternoon will be within a few degrees of those today. Got beach plans? Check out the BEACHES section of the AFD for safety tips and more information on the Beach Hazards Statement and Coastal Flood Advisory. && .LONG TERM... Issued at 1230 PM PST Sun Nov 8 2026 (Tuesday through next Saturday) High pressure will continue to strengthen over the Bay Area and Central Coast on Tuesday and into Wednesday. This will result in temperatures across the interior Central Coast to be some 10-15 deg F above normal with the northern portions of our region remaining 5- 10 deg F above. The high pressure is forecast to shift eastward into the Desert Southwest on Thursday as the trough off of the West Coast deepens. Rain chances have largely been pushed back to Friday and Saturday with both deterministic GFS and ECMWF showing a cut-off low pressure system developing and pushing inland over Southern California or Baja California from Friday through Sunday. However, there is still chances for rain during this timeframe as the main trough axis shifts inland across the Pacific Northwest and Northern California Saturday through Monday. Be sure to check back for the latest forecast information as we near late week and into the weekend. Exact details on the system`s trajectory and expected rainfall && .AVIATION... (00Z TAFS) Issued at 339 PM PST Sun Nov 8 2026 Currently VFR with stratus off the coast and high clouds streaming in from the west. Moderate confidence on a persistence forecast for tonight. Ceilings will return for most with bayshore and coastal terminals likely on the IFR/MVFR cusp with LIFR conditions more likely for interior terminals. Diurnal winds will prevail. Vicinity of SFO...Currently MVFR with northerly flow and haze. Winds will continue to back through the afternoon to become westerly/northwesterly. Low to moderate confidence on a ceiling on the cusp of IFR/MVFR developing at the terminal tonight, likely between 11Z and 18Z. Diurnal winds will prevail. SFO Bridge Approach...Moderate confidence on clouds below FL070 developing as soon as 06Z with conditions improving by 16Z. Monterey Bay Terminals...Currently VFR with westerly flow at MRY and VFR with northwesterly flow at SNS. Moderate confidence in a persistence forecast. Ceilings on the cusp of IFR/MVFR will make a run for the terminals tonight, but the limiting factor will likely be drainage flow as it will bring in drier air and keep stratus out over the Monterey Bay. Diurnal winds will prevail. && .MARINE... (Tonight through next Friday) Issued at 339 PM PST Sun Nov 8 2026 Moderate to fresh breezes combined with a dynamic sea state continue to produce rough to very rough seas, with hazardous conditions for small craft across both our coastal and outer waters through Monday. Elevated mixed long period swell will continue through the week, increasing further by the end of the forecast period. && .BEACHES... Issued at 1230 PM PST Sun Nov 8 2026 Beach Hazards Statement: Final day of the weekend and beach weather will be rather nice. However, the surf zone won`t be nice. In case you missed it, a Beach Hazard Statement remains in effect. Latest buoy obs show the surf zone remains energetic due to mixed swells and longer periods. As such, large shore break, sneaker waves, and stronger rip currents will be possible. Breaking waves of 12 to 16 feet are expected at exposed beaches and up to 18 ft at favored break point. 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 if you`re not an experienced swimmer to avoid hazardous surf and never turn your back on the ocean! There may be a lull in wave activity early next week, but longer range forecasts show additional swells impacting the coast late next week. 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 to be 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.

793 FXUS66 KOTX 090138 AFDOTX Area Forecast Discussion National Weather Service Spokane WA 538 PM PST Sun Nov 8 2026 .KEY MESSAGES... - Unsettled pattern will bring multiple rounds of precipitation to the area this week. - Risk of Cascades debris flows and rock slides this week from periodic rain and snow melt. - Low probability of River Flooding on the Stehekin River by Stehekin. && .SYNOPSIS... Unsettled weather conditions continue throughout the next seven days with a series of systems bringing periods of rain, high mountain snow, and gusty winds. && .DISCUSSION... Gusty winds in the wake of this mornings cold front will continue into the afternoon hours before returning to much calmer conditons this evening and overnight. Otherwise, a mild and unsettled week is expected as a progressive weather pattern continues across the region bringing multiple waves of precipitation chances, and increasing snow levels. The main concerns this week: The main concerns will be for debris flows/rockslides, particularly in and around burn scars in the Cascades due to snow melt and rain. Chances of 24 hour rain amounts exceeding an inch near the Cascade crest are are up to 40-60+% (NBM, even higher in REFS) Tuesday, and includes up to 45% chance in the western portion of the Little Giant burn scar. Similar probabilities again for the weekend. As discussed in previous forecasts, most rivers should behave, however the Stehekin River at Stehekin is showing a 10% chance of reaching Minor Flood Stage (20.5 ft) on Wednesday. These probabilities decrease briefly for Thursday/ Friday and return with a 10% of exceeding Minor Flood Stage on Saturday. When to expect precipitation: The next round of precipitation is expected to pick up tomorrow evening across the area. Snow levels will be 5000ft + near the Canadian border and 7000ft over SE WA into the Central Panhandle Mountains. Tuesday follows with another round of precipitation primarily across northern WA and N ID Panhandle, with snow levels continuing to increase into the 7000-8000+ ft range. There is very good agreement across ensembles of a brief period of ridging over the region Wednesday and Thursday while a trough digs south just off the west coast. Most ensemble data points to the region being influenced by troughing / southwest flow for the weekend as a low pressure system develops off the coast of BC. There are some inconsistencies across ensembles of how strong and east this system is placed by the weekend. However, expect precipitation to return for the weekend along with breezy winds. && .AVIATION... 00z TAFS: VFR conditions will prevail across much of the TAF period. Winds will continue to subside. Skies will remain variably cloudy, thickening and lowering into Monday with a chance of rain developing in the afternoon. Better chances hold off until after 00Z Tuesday. FORECAST CONFIDENCE AND/OR ALTERNATE: High confidence in VFR conditions through much of the TAF period. Lower confidence in MVFR conditions early tomorrow morning. Most sites have up to a 20-30% chance of MVFR or lower cigs between 06 and 12z Monday. ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports, please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard && .Preliminary Point Temps/PoPs...

875 FXUS66 KPDT 082219 AFDPDT Area Forecast Discussion National Weather Service Pendleton OR 219 PM PST Sun Nov 8 2026 .KEY MESSAGES... - Mostly dry, mild, and locally breezy today. - Region-wide precipitation chances return Monday, then pivot to the Washington Cascades on Tuesday. - Mostly dry, warm, and locally breezy conditions east of the Cascades Tuesday through Thursday. && .DISCUSSION... GOES-18 imagery shows a quasi-zonal jet over the forecast area this afternoon. Radar reveals some isolated showers across the mountains, mainly the Cascades, with otherwise dry conditions apparent within the lowlands. Upstream, troughing is evident in the northeast Pacific, and the shortwave in the vicinity of 38N, 146W is the main feature of interest for our forecast area as we move forward in time. The aforementioned shortwave is expected (95% confidence) to track east-northeast across the Pacific and move onshore Monday. The wave will facilitate widespread precipitation chances through the day. Otherwise, locally breezy southwesterly to westerly winds are forecast, and temperatures will be near to several degrees above normal. The shortwave will likely (90% confidence) exit to the east by early Tuesday, with another wave and warm frontal passage slated for Tuesday. That said, precipitation chances on Tuesday will pivot to the Washington Cascades; locations east of the Cascades have low (20% or lower) chances of precipitation. Ensemble guidance is in excellent agreement (at least 90% of members) that the 500-hPa pattern will amplify Tuesday through at least Thursday. Under this quasi-blocking pattern (troughing over the East, ridging over the Plains and West, and troughing upstream in the Pacific), well-above-normal temperatures and periods of breezy to windy southerly to southeasterly winds are forecast. Clusters of ensemble QPF show high likelihood (90% of members or greater) that notable precipitation will be confined to the Washington Cascades on Tuesday, with little to no QPF on Wednesday. Under this pattern, precipitation is largely restricted to the Cascades with warmer, drier conditions to the east under the upper-level ridge. Significant uncertainty in the 500-hPa pattern develops in ensemble solutions Friday into the weekend. Ensemble guidance continues to trend towards a solution that splits off a piece of energy and develops a closed low offshore in the Pacific before eventually taking it south of our forecast area into California or the Southwest. That said, all members are showing another wave behind it, with a return to broad troughing in the Northeast Pacific, perhaps extending into the Pacific Northwest through the weekend. Should the additional troughing develop, precipitation chances will increase across the region heading into the weekend. Moreover, confidence is medium (40-60%) in breezy to windy conditions. Significantly cooler temperatures will be delayed if/when the trough/low moves onshore. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... VFR conditions currently across all sites, which will stay the course through the period. Breezy winds will subside this evening as a brief ridge of high pressure passes the area. An incoming system will push into the region from the southwest, bringing a return of light showers to most sites toward the end of the period. 75 && .Preliminary Point Temps/PoPs...

592 FXUS65 KREV 082031 AFDREV Area Forecast Discussion National Weather Service Reno NV 1231 PM PST Sun Nov 8 2026 .KEY MESSAGES... * Dry weather prevails through most of the week with warmer than normal daytime temperatures. * Periods of increased breezes will pose minor impacts to aviation and recreation this evening through Monday evening. * A wetter and windier pattern continues to be delayed. Could see increased winds as early as Friday, with precipitation moving in Saturday. && .DISCUSSION... Visible satellite imagery shows a band of high clouds moving through the region this afternoon. This band is associated with a shortwave trough in the PacNW. The approach of another shortwave trough right behind it will slightly tighten the pressure gradient this afternoon. Thus, expect an increase in ridgetop southwesterly gusts up to 45 mph and in northeast California and northern Washoe county 15-30 mph. Gusts in the rest of the area should remain in the 10-20 mph range. Winds continue to be elevated overnight in the ridgetops. Tomorrow with the actual passage of the trough and its associated dry cold front winds will be slightly stronger, about 5 mph higher than today, especially for northeast California tomorrow afternoon and early evening. As the upper trough quickly moves away, a high amplitude upper level ridge will settle in the region leading to 5 to 10 degrees above normal temperatures through the rest of the work week. This will be accompanied by lighter winds and mostly clear skies too. While the ridge dominates the pattern over the western US, a broad upper level trough over the northern Pacific will split into two systems. The new closed upper low sinks towards SoCal moving towards Arizona/New Mexico this weekend. The development of these systems have brought uncertainty in the scenarios for this weekend as the models struggle to figure out the final solution. They keep pushing the precipitation for our area later into the weekend and early next week. Ensemble models only have very few members showing any kind of precipitation Thursday and Friday, with an uptick by Saturday and the main consensus (for now) by Sunday into Monday. Probability-wise our chances for precipitation Thursday are below 5%, with Friday/Saturday between 5-25%, and Sunday 40%+ for the Sierra Front and the California-side of our area. Winds are also expected to increase this weekend, especially over area mountains. Anyway, this is likely to change as you have seen over the past several days. -HC && .AVIATION...

975 FXUS66 KSTO 082055 AFDSTO Area Forecast Discussion National Weather Service Sacramento CA 1255 PM PST Sun Nov 8 2026 .KEY MESSAGES... - Dry weather, above normal temperatures, and periodically breezy north to east winds Tuesday through Friday - Shift toward active weather pattern late week into early the next week, with the potential for heavy rain and heavy mountain snow, and gusty onshore winds; Low confidence persists in the timing and amount of potential precipitation && .DISCUSSION... Today-Mid Week: Warm and mainly dry weather continues through mid-week with generally high pressure ridging over the area. A weak disturbance passes to the north today, and another Monday afternoon, flattening the ridge slightly. No precipitation is expected today, with just a slight chance of light showers extending from the coast into far northwestern Shasta County Monday afternoon. Light winds, mostly clear skies and some low level moisture will bring the potential for some morning mist and some patchy fog Monday morning. The lack of wet ground will limit this to mainly areas near area rivers and lakes. The best potential is around the Delta, Sacramento metro area and the northern San Joaquin Valley, though models hint this could spread as far north as Marysville. Probabilities for visibility dropping below a mile are around 30-50% for metro areas, 50-70% for adjacent rural portions of the area. This fog and mist are expected to quickly mix out and disperse by late morning. The potential for fog/mist Tuesday morning shifts to mainly south of I-80, with a 20-50% chance of visibility dropping below a mile. Temperatures trend a little warmer early this week as ridging rebounds. Highs peak on Tuesday, into the mid to upper 70s for the Valley and Delta, about 10 degrees above normal for this time of year. As the ridge axis shifts eastward Wednesday, temperatures will decrease slightly, but will still be about 5 to 10 degrees above normal. The building ridge pattern will bring some breezy northerly winds in the Valley Tuesday, though gusts should generally be limited to 15 to 20 mph, peaking mid-day. East to northeast winds develop over mountain ridges and through canyons Tuesday night into early Wednesday, with gusts locally to around 20 to 30 mph. Late Week Into Next Weekend: Ensembles continue to show the potential for a shift toward an active weather pattern by the weekend, with chances for heavy rain, heavy mountain snow and breezy winds. However, cluster guidance still indicates uncertainty regarding the exact position, timing and development an approaching trough from the Gulf of Alaska toward the California coast. Ensembles continue to trend toward a further southward trajectory of the initial ejecting shortwave, closing off well off the coast Wednesday-Thursday as strong high pressure ridging centered over the 4-Corners region persists. The main trough moves inland Friday into the weekend, with the ridging shifting eastward. This brings the general onset of precipitation from sometime between Friday and Saturday. The likely wettest period will be over the weekend. The spread between forecast low and high end amounts of rainfall and mountain snow totals remains quite large, with a range of possibilities. Overall though, confidence in a cool, wet, unsettled pattern late week into early the next week continues to increase. Anyone with travel or outdoor plans should be sure to stay up to date with the latest forecast information. && .AVIATION... General VFR conditions are generally expected to prevail at TAF sites over the next 24 hours, although there is a 40-70% chance for MVFR/IFR visibility in FG/BR at Valley and Delta sites returning after 09z this evening and continuing at times through 17z. Light and variable winds persist across the forecast period at TAF sites. && .STO WATCHES/WARNINGS/ADVISORIES... None. && $$

818 FXUS65 KMSO 082030 AFDMSO Area Forecast Discussion National Weather Service Missoula MT 130 PM MST Sun Nov 8 2026 .DISCUSSION... KEY MESSAGES: - Gusty Winds and Choppy Lakes Today - Periodic Showers Through Tuesday, Limited Winter Impacts - Mid-Week: High pressure, bringing valley inversions and fog Radar returns this afternoon indicate light showers in northwest Montana along the Idaho border and in the Idaho Panhandle. Satellite imagery depicts some moisture still streaming into the Northern Rockies, supporting those showers in the northwest. The position of the upper level jet, along with a series of weak disturbances moving along the Canadian border, will keep isolated showers and cloudy skies in the forecast for northwest Montana through Monday as daytime high temperatures stay a few degrees above normal. A more pronounced disturbance will move into the Northern Rockies on Tuesday, bringing more widespread precipitation. Temperatures stay on the high side, though, so chances for snow will be limited to elevations above about 6000 feet. High pressure will build on Wednesday, resulting in strong valley temperature inversions and potential for morning fog along the more pronounced valleys of western Montana such as the Flathead, Mission, Missoula, and Bitterroot valleys. As is typical with inversions, forecasting daytime high temperatures becomes a challenge, so high temperatures midweek and beyond may not reach their full potential due to persistent stratus cloud cover and cold air pooling in the valleys. Looking toward the end of the forecast period, ensemble guidance indicates the ridge axis migrates eastward. This will open the door to a more progressive southwest flow, reintroducing precipitation chances and effectively scouring out any lingering valley inversions. && .AVIATION...A cold front continues to push across the Northern Rockies this afternoon causing gusty westerly winds. All terminals with the exception of KSMN should experience gusts out of the west between 20 to 30 kts for the remainder of the afternoon then diminish after 09/00z. Light showers are expected to persist over north central Idaho up into northwest Montana today into the overnight hours. These showers will have minimal impacts to area terminals, but periods of obscured mountains should be anticipated. && .MSO WATCHES/WARNINGS/ADVISORIES... MT...None. ID...None. && $$

Record high temperatures possible Wednesday through Saturday. - Cooler and wetter Sunday and beyond. && .SHORT TERM /Through Tuesday Night/... Issued 200 PM MST SUN NOV 8 2026 A weak upper trough will bring scattered light rain showers to northern mountains tonight. A stronger Pacific trough will bring a better chance of light rain Monday night, again to northern areas. Total precipitation should stay less than .10 inch. Southern areas will be mostly cloudy but dry. Temperatures will lower slightly as the two troughs move through. Light winds through Tuesday mainly from the east through south, increasing Tuesday night. && .LONG TERM /Wednesday through Sunday/... Issued 200 PM MST SUN NOV 8 2026 High pressure will peak over the region on Wednesday, with temperatures reaching about 10-15 degrees above normal and near daily record highs. Warm and dry conditions will continue through early Saturday, with little change day to day from Wednesday through Friday. High pressure will shift east by late Friday as southwest flow takes over ahead of a shift to cooler and wetter weather. An atmospheric river will impact the Pacific Northwest on Friday and into the weekend, with the upper level trough eventually moving east and bringing remnant moisture into southeast Oregon and southwest Idaho. Models diverge on when the trough will move into the region, however all favor a cool and wet pattern for Sunday into early next week. This system will also bring breezy southerly winds and a steady cooling trend beginning Sunday. Precipitation chances increase to 20-40% chance on Saturday in high terrain in northeast Oregon and the West Central Mountains in Idaho. Valley locations look to stay mostly dry through Saturday evening. Precipitation chances increase area wide by Sunday, with a 20-40% chance in valleys, and 40-60% in higher elevations north and west of the Snake River Valley.

(This afternoon through next Sunday) WEATHER PATTERN OVERVIEW: Current satellite imagery shows mostly clear skies with a few high clouds moving across northern Nevada. An upper level high pressure system off the coast of California will dominate our upper air pattern for the majority of the week, bringing us mostly sunny skies and afternoon highs in the upper 50s to mid 60s. Winds are expected to remain light, except for the northern most portions of Nevada which could see up to 20 mph gusts Monday afternoon. Low temperatures this week are expected to remain in the 30s, with some areas of higher elevation seeing lows in the upper 20s. Models continue to show signs of an upper level trough as well as an atmospheric river event coming through later in the coming weekend. With the event being so far out, there is still plenty of uncertainty in the timing, placement, and strength of the event. Model guidance shows signals of potential rainfall and snow showers associated with this trough, we will continue to monitor model trends over the next few days. FORECAST CONFIDENCE & DEVIATIONS: High confidence in the upper level ridge dominating the forecast for the week. Low confidence on the strength and impacts of the trough next weekend. && .AVIATION...
