The National Weather Service forecast for the greater San Francisco Bay Area for Saturday called for a cold front with rain, and also issued other alerts for the region.
Daytime highs will be mostly in the 50s in the Bay Area. Overnight lows will be in the low 40s on the coast, in the mid-40s around the bay and inland.
The NWS issued a special weather statement — covering much of San Francisco, the Peninsula, the South Bay, the East Bay as well as areas toward Santa Cruz — due to wind gusts possibly reaching up to 40 mph. It warned those gusts "could knock down tree limbs and blow around unsecured objects."
