Moist, cooler conditions and coastal drizzle set in for an extended stay in San Francisco. According to an early morning update from the National Weather Service's San Francisco office, this pattern is expected to linger on throughout the week, with the possibility of some light rain by Thursday night into Friday.
The NWS Forecast Office reported that temperatures will bob in the upper 50s to lower 60s near the coast, with the warmest interior spots hitting the lower 70s. Coastal drizzle has already been observed and is predicted to revisit us tonight into Wednesday morning, with areas under persistent cloud cover remaining cooler. Overnight, temps will hover in the mild zone, from the mid 40s to low 50s.
The outlook doesn't brighten up much for the remainder of the week. "Cooler, unsettled conditions will continue Wednesday through Friday," the NWS statement notes, the region seemingly trapped under the whims of an upper-level disturbance. Daytime highs will stick to the cool side, with the mercury peaking in the upper 50s to low 60s near the coast and just a nudge higher inland.
An update via the NWS Bay Area's X feed also confirmed this, highlighting the presence of "coastal drizzle being reported along the coast and in favored upslope regions this morning." Nightfall will not bring much relief as it promises another round of light coastal drizzle. Meanwhile, robust northwest winds will assert themselves Thursday and Friday, with gusts nearing 25-45 mph by the coast and in higher terrain, enough to necessitate a Small Craft Advisory in select marine areas.

Though the weekend may usher in a slight upturn in temperatures, it seems the region can only hold hopes for a brief reprieve, as the National Weather Service underscores the hesitant promise of a "shortwave ridge builds in wake of the exiting trough," bringing conditions closer to seasonal averages.
