The near 70-degree weather that warmed many spots over the weekend will be replaced with highs in the 50s by Wednesday, with some areas posting low temperatures below freezing for the first time this season.
"Monday will probably be the last day of the above season norms," said Bob Benjamin, a forecaster with the National Weather Service. "We're probably going to drop almost 10 degrees this week."
A dry cold front from Alaska will move into the Bay Area on Tuesday afternoon, Benjamin said, dropping overnight temperatures in San Francisco into the low 40s.
Many areas outside the city will be much colder, particularly in the North Bay. Lows in Santa Rosa are forecast to hit 31 degrees Wednesday and the upper 20s the rest of the week, according to the weather service.
The cold snap is expected to last at least through the weekend.
