San Francisco, California –
Headlights glow through low clouds this morning as patchy fog hugs city streets, softening skylines and dampening pavement before sunrise. The air feels mild, but visibility drops quickly in spots near the coast and bay.
According to the National Weather Service Bay Area office, fog remains the main concern early, followed by filtered sunshine and highs climbing into the mid-60s. Winds stay light, allowing clouds to linger longer near the water and along Highway 1. Commuters should expect brief slowdowns where fog thickens before midmorning.
Conditions stay relatively quiet through Monday. Clouds increase late, signaling a shift already taking shape offshore. By Tuesday, a Pacific system moves inland, bringing a growing chance for rain by late morning and steadier showers by evening. Rain probabilities climb near 60 percent, with locally higher coverage after sunset.
Drivers across San Francisco, Daly City, and the Peninsula should prepare for slick roads Tuesday night into Wednesday. Wet pavement along U.S. 101, I-280, and city arterials may slow evening travel, especially after a dry stretch that allows oil buildup. Reduced visibility could return where fog and rain overlap.
While California turns unsettled, much of the eastern U.S. remains locked in deep winter. Arctic air continues to grip the Great Lakes and Northeast, keeping lakes frozen and reinforcing a strong temperature contrast nationwide. That contrast helps steer active weather toward the West Coast this week.
By midweek, showers taper but do not fully disappear. Temperatures hover near 60 degrees, close to seasonal norms. Looking farther out, late-week trends point toward a gradual warm-up with more dry breaks, hinting at a calmer pattern heading toward next weekend. Seeing fog or rain slowdowns where you are?
