Higher-than-normal temperatures over Thanksgiving Day will end this week as a cold snap heading for the Bay Area is expected to blanket the region by mid-week, according to the National Weather Service.
A drastic drop in temperature is predicted around the Bay Area by Wednesday, with daytime highs and nighttime lows expected to drop up to 15 degrees, forecaster Diana Henderson said.
In San Francisco and around the Bay, overnight lows are predicted to be in the low 40s, Henderson said. Daytime highs will likely be in the low 50s.
In inland valleys in the North Bay, overnight lows on Wednesday could dip well below freezing to around 28 degrees, Henderson said. In the East Bay and on the Peninsula, overnight lows are likely to be in the mid 30s, according to the NWS.
The cold snap is predicted to last for several days into the weekend.
