Area Forecast Discussion ...UPDATED National Weather Service San Francisco CA 1110am PDT Sunday July 20 2025 Issued at 914am PDT Sunday July 20 2025 Stratus coverage, while still widespread, is a bit more patchy across the Bay Area than it was yesterday morning. The 12Z OAK sounding shows the marine layer compressed to around 1500 feet overnight which would help explain why the stratus coverage was patchier. Pockets of diminished visibility along the coast have started to improve with further improvement expected as stratus clears by mid to late morning. Gusty winds remain on track to develop this afternoon/evening with the only adjustment to the .SHORT TERM... Issued at 217am PDT Sunday July 20 2025 (Today and tonight) The forecast for the most part is starting to sound like a broken record: morning stratus layer clearing to the coast by the afternoon with seasonably cool temperatures. While the overall weather picture is the same there are some details that differ: high temps, marine layer depth, and winds. The upper level ridge that brought some inland warmth Saturday has weakened and is being replaced by an upper level trough/lower 500mb heights. The overnight satellite fog product shows the marine layer has better coverage than 24 hours due to the building upper level trough. Have added some coastal drizzle/patchy fog to the forecast given the current marine layer set up. The upper level trough will also help to knock inland temperatures down a few degrees. The biggest weather change for today will be the winds. For several days now we've been mentioning increasing winds late Sunday into Monday. Latest guidance continues to advertise a solid push of winds. In fact, onshore gradients (SFO-SAC) are projected to be 4 to 5 mb later this afternoon and evening yielding some robust winds for the East Bay gaps/passes and West Delta region. Borderline for a wind advisory, but gusts in the 30-40 mph with a few isolated up to 50 mph will be possible. It will be windy along the coast, higher terrain, and favored valleys, but not as strong as the East Bay. It goes with out saying, but the uptick in winds will create increased fire weather concerns for the East Bay. While winds increase humidity values are lowering to the 25-40% range. While not critical RH the wind will override it. ERC chart values take a dip today the more wind based index of the Burn Index reaches in the 90th percentile. So that means, flashier fuels and more flammable live fuels could carry fire. Speaking of fire weather concerns a classic nocturnal drying event is taking place over the Santa Lucia range. As stratus rolled through the Salinas Valley rapid drying occurred above it with a sensor on Chews Ridge dipping into the single digit RH. Sunday night into Monday: Solid onshore flow remains with breezy conditions lingering in the East Bay. The marine layer will deepen with more coastal drizzle. Long Term Issued at 254am PDT Sunday July 20 2025 (Monday through Saturday) To kick off another work week more of the same - night/morning clouds with afternoon inland sunshine. Onshore winds ease slightly early Monday before ramping back up Monday afternoon/evening favoring the inland gaps/passes. Thereafter pretty benign weather continues into next weekend. Marine layer is locked in with cooler the seasonal temperatures thanks to an anomalously low upper level trough overhead. Some longer range guidance even deepens the trough and has an a cut- off low form over the region by Thursday. Simply put, if you're enjoying the cooler weather with some afternoon sunshine you'll enjoy the long term forecast. Marine (Today through Friday) Issued at 914am PDT Sunday July 20 2025 Moderate breezes to near-gale force wind gusts are forecast today and into Monday. This will result in hazardous boating conditions for smaller vessels near and across the northern San Francisco and San Pablo Bays. Hazardous boating conditions should also be anticipated across northern outer waters beyond 10 nautical miles from the shore. In addition, northwesterly coastal jets with strong breezes are anticipated this afternoon across northern Monterey Bay and near Point Sur. These strong breezes will persist into the pre-dawn hours on Monday across the Big Sur coastline. Slight to moderate seas persist through the remainder of the forecast period. Winds ease some through Tuesday, except across southern portions of the Big Sur coast, where strong northwesterly breezes persist. Otherwise, reduced visibility should be anticipated during the morning hours due to fog/drizzle. NOAA San Francisco Bay Area Office: Watches - Warnings - Advisories CA...None.
