| Area Forecast Discussion National Weather Service San Francisco CA 1157pm PDT Wednesday September 23 2026 ...New SHORT TERM, Long Term .KEY MESSAGES... Updated at 1103am PDT Wednesday September 23 2026 - Warming trend continues into Thursday bringing pockets of moderate HeatRisk across parts of the Bay Area and north Central Coast. - Cooler conditions arrive Friday into the weekend. - Near seasonal temperatures early next week. .SHORT TERM... Issued at 1157pm PDT Wednesday September 23 2026 (Tonight through Friday) There is a large variation in temperatures across our forecast area, with 50s in a shallow marine layer along the coastline and 60s, 70s and near 80 inland and at elevation. The warmth is due to ongoing thermal and height ridging aloft while a narrow channel of cooler air over the coastal waters is undercutting the ridge. There is very little to no stratus or fog over the coastal waters since there is also warmer surface to near surface air temporarily mixing in on northwest winds. Even though it's dry aloft i.e. good conditions for outward radiative cooling to help stratus and fog develop, the air/sea interface is not thermodynamically supportive of stratus/fog at the current time. However, 1000 mb NAM forecasts a rapidly southeastward moving cooler air mass arriving in our coastal waters between midnight and Thursday morning, which may briefly fall into syncopation with the remaining rhythm of radiative cooling in the early morning. This combination will likely help produce a few areas of coastal stratus and fog, while inland areas stay clear since the marine layer depth is forecast to remain near steady. Daytime highs on Thursday will warm up similarly to Wednesday's daytime highs with mid 60s to 70s near the immediate coastline, 70s/80s bayside to the 90s well inland. The ridge will weaken Friday with onshore winds deepening, sending cooler air inland. Daytime highs Friday will range from the 60s/70s coastside to the 80s well inland. Long Term Issued at 1157pm PDT Wednesday September 23 2026 (Friday night through next Wednesday) For the weekend, 500 mb troughing will return once again which will keep temperatures cooler than normal for late September. It should be a beautiful weekend temperature-wise. After the weekend cooling trend, temperatures will warm up again by the middle of next week. Marine (Tonight through next Tuesday) Issued at 934pm PDT Wednesday September 23 2026 North to northwest breezes will continue tonight, with strong gusts developing Thursday afternoon that will persist through Friday, especially Friday afternoon and evening from nearshore Santa Cruz to Big Sur with seas responding and becoming rough into the weekend. Fire Weather Issued at 440am PDT Wednesday September 23 2026 Marine layer returned again impacting lower portions of the district this morning with excellent RH recovery. Similar to yesterday morning patchy fog will impact the N Bay Valleys, Monterey Peninsula and the Salinas Valley. Unlike yesterday two other notable differences: the exact footprint of the marine layer is slightly different with less coverage over the E Bay Valleys and along the Big Sur coastline and moderate to poor recoveries above the marine layer. Speaking of the drier conditions aloft, RH recoveries are 15 to 50 pct drier depending on locations. In other words, nocturnal drying returned. Otherwise, warmer and drier across the board, especially interior locations. MM NOAA San Francisco Bay Area Office: Watches - Warnings - Advisories CA...None.
