The National Weather Service forecast for the greater San Francisco Bay Area for Saturday calls for rain. Daytime highs will be mostly in the high 50s to low 60s on the coast, in the high 50s to low 60s around the bay, and in the high 50s to low 60s inland. Overnight lows will be mostly in the high 40s to high 50s.

Rain is back in the Bay Area on Friday after three and a half weeks of dry weather, which has been one of the driest January's on record. Rain is light on Friday but intensifies on Saturday with a moderate-strength atmospheric river and we may see flooding on roads and on smaller streams and creeks.
