838 FXUS66 KLOX 262200 AFDLOX Area Forecast Discussion National Weather Service Los Angeles/Oxnard CA 200 PM PST Wed Nov 26 2025 .SYNOPSIS...26/109 PM. Dry weather will continue at least through the middle of next week. Well above normal temperatures are expected again on Thanksgiving Day before cooling develops over the weekend as an upper low approaches the area. && .SHORT TERM (TDY-SAT)...26/146 PM. It was a very warm, offshore Santa Ana day across the area, especially across coast and valley areas south of Pt Conception. Highs were well into the 80s in many areas below 1000 feet elevation. Despite the heat it wasn`t nearly warm enough for any records as of 1pm. It wasn`t quite as warm along the Central Coast, although Port San Luis, just northwest of Pismo Beach, reached at least 80 thanks to downsloping winds off the Irish Hills and Morro Bay was at least 71. In contrast, only low to mid 60s across the far interior. The pattern is similar on Thanksgiving Day but offshore flow will be weakening and perhaps more importantly there will be quite a bit of mid and high level clouds arriving from the southwest tonight into tomorrow. These factors make tomorrow`s temperature forecast very uncertain. Confidence is relatively high that it will still be above normal in all areas, but the uncertainty of thickness of the cloud cover and how fast the offshore flow will weaken make this a very tricky forecast. Highs could be very similar to today, or as much as 10-12 degrees cooler. Coastal areas will be the most likely areas to cool due to the increasing influence of the onshore flow. By Friday and Saturday the cooling trend for coast and valleys will be well established bringing highs back to the 60s and 70s area- wide. Meanwhile, across the far interior areas like interior SLO and the Antelope Valley, temperatures will be warming to the 70s Friday but then cooling again Saturday as the next trough drops into the Great Basin. .LONG TERM (SUN-WED)...26/200 PM. Models have come into good agreement that the next upper level trough arriving along the West coast Saturday will take an inside track east of the Sierra mountains Sunday and Monday which likely means no rain for southern California, but cooler than normal temperatures and possibly some gusty north to northeast winds at times, especially in the mountains. The models are keeping most of the stronger winds farther east but can`t rule out some low level advisory winds in some areas into early next week. Otherwise, a quiet first half of next week is expected with temperatures near seasonal norms. With the trough passing to the east and northerly flow aloft skies should remain mostly free of marine layer stratus. There are some model solutions showing rain later next week but models continue to provide a wide range of possible outcomes, from dry to very wet. && .AVIATION...26/1751Z. Around 1626Z at KLAX, there was no marine layer. There was a weak sfc based inversion with a top near 600 ft and a temperature of 21 C. Overall, high confidence in 18Z TAF Package. There is a 30% chance for V/LIFR conditions after 14Z Thursday at KPRB. Otherwise, VFR conditions are expected. KLAX...High confidence in TAF. VFR conditions with no significant east wind component expected thru fcst pd. KBUR...High confidence in TAF. VFR conditions are expected. && .MARINE...26/118 PM. Conditions will remain relatively mild through Thanksgiving. However, Localized gusty offshore winds will affect the nearshore waters from Cayucos to Morro Bay and from Point Mugu to Topanga Beach at times through Thursday morning. Winds could gusts to 25 kt. Small Craft Advisory (SCA) winds and/or seas are expected across the Outer Waters likely starting Friday morning and persisting at times through the weekend. Periods of Sub-SCA conditions are probable especially within 10 to 30NM from the shore and during the morning hours. Chances for SCA conditions within 5NM are low, but highest on Friday, and near Point Conception. Conditions are likely to remain below SCA levels for the inner waters south of Point Conception during the aforementioned period. Moderate confidence in seas peaking 10 to 12 feet across Outer Waters and 4 to 6 feet across the Santa Barbara Channel. && .LOX WATCHES/WARNINGS/ADVISORIES... CA...NONE.
