| Area Forecast Discussion National Weather Service San Francisco CA 1033am PDT Thu September 24 2026 Issued at 920am PDT Thu September 24 2026 Thursday is the last day of warm conditions this week, maintaining moderate HeatRisk across the interior East/South Bay valleys and Big Sur coastline. A parade of high clouds ahead of a dry cold front pushes through today with the actual frontal passage occurring overnight. Early Friday morning, a mix of low and high clouds with moderate to strong onshore winds, around 15 to 20 mph primarily at the coast, will result in widespread cooler conditions Friday into the weekend. No precipitation is expected with this system as it cruises through the Bay Area and Central Coast. .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 (Today through Tuesday) Issued at 1032am PDT Thu September 24 2026 Light to moderate northerly breezes expected through early Thursday night. Building high pressure in wake of a passing cold front will usher in fresh to strong breezes Friday into Saturday for most of the waters. Near gale force gusts will be possible in the wind-prone areas nearshore. The stronger winds will lead to an elevated sea state and hazardous conditions for small craft. Fire Weather Issued at 450am PDT Thu September 24 2026 Marine layer is pretty much non-existent overnight. That led much less RH recovery across the district at both lower and higher elevations. NGFS (Global Forecast System) gave us a hit earlier in the night as the Timber Fire had an northern perimeter flare up. Even FireGuard showed the heat as well. Not completely surprised given temps in the 70s and RH recovery around 30 pct near Timber. Otherwise, notes for today will be another mild and dry day across the district. Hottest and driest across the interior portions. Do expect an uptick with winds late tonight and Friday as a dry front moves through. Cooler and wetter for Friday and over the weekend.
