The National Weather Service San Francisco Bay Area forecasts a warming and drying trend starting Tuesday after a relatively quiet Labor Day weekend. Temperatures today, the cusp of meteorological autumn, are expected to hover near or slightly below typical for this time of year, barring the higher elevations, which may experience gustier conditions due to onshore winds funneled through gaps and passes.
According to the NWS San Francisco Bay Area update, a marine layer about 1,500 feet deep could bring coastal drizzle this morning, driven by the mechanics of a cutoff low off the coast and local topography. The marine layer is anticipated to retreat toward the coastline by the afternoon. In turn, the NWS has highlighted fire and water safety warnings, advising guests to enjoy the holiday responsibly.
Looking ahead, ridging is expected to intensify into next week, causing a rise in temperatures and heightening fire weather concerns, particular from Tuesday through Friday, as reported in the NWS's long-term forecast. Relative humidity recovery is projected to be poor above the marine layer, increasing the risk of fire, especially in regional mountains and forests.
Moreover, the NWSBayArea's X post warned of smoke from the Coffee Pot Fire drifting into the East and North Bay overnight. While most of the smoke is expected to remain elevated, the potential for limited surface-level effects exists. Harbor gusts and the strengthening of northwest winds near coastal regions such as Point Sur are poised to build moderate seas as the week progresses, as the smoke is cleared by the winds, which follow the synoptic pattern.
