California – Low clouds hang over the Bay early, and the air feels damp despite quiet streets. Morning calm won’t last long. A developing Pacific system is already lining up to bring widespread rain and reduced visibility to San Francisco and surrounding communities.
According to the National Weather Service, today stays mostly cloudy with highs near 63 degrees. Winds remain light, but moisture steadily increases. Late tonight, light rain becomes possible, especially closer to dawn, setting up slick pavement for early travel.
The main impact arrives Tuesday. Rain becomes likely by afternoon and intensifies into the evening hours. Wet roads quickly spread across downtown San Francisco, the Embarcadero, and Highway 101. Visibility drops at times as patchy fog forms, especially after sunset. Drivers should plan extra time during the evening commute and watch for pooling water in low spots.
Showers linger Tuesday night and continue into Wednesday. Periods of rain remain likely through much of the day, with fog possible during the morning hours. Temperatures cool into the upper 50s, keeping conditions raw and gray. While flooding is not expected, repeated rainfall may slow traffic and strain drainage in urban areas.
By Wednesday night, rain chances gradually taper. Thursday brings improvement. Skies begin to brighten, and only spotty light rain remains possible. Friday looks noticeably calmer, with sunshine returning and highs climbing back into the low 60s.
Looking into early next week, longer-range trends suggest a modest warming pattern. Temperatures may run above normal, hinting at a quieter stretch after this midweek system clears.
