Meanwhile, the springlike weather that the Bay Area and northern California have enjoyed for the last week is about to end as an arctic cold front puts most of the country into a deep freeze.
The Bay Area forecast calls for temperatures to start cooling Sunday with a rapid change in the weather by Monday or Tuesday.

On Monday, a dry cold front will bring cooler air to the Bay Area with blustery winds by Monday evening. Lows on Tuesday and Wednesday are expected to be 39 in San Francisco, 33 in San Jose and 30 in Livermore.
A weather system will bring small chances for rain showers and high elevation snow to parts of the area on Tuesday. Best chances for the Central Coast. Also look for *much* colder temps through mid week. #cawx pic.twitter.com/UM6SwGPAd9
