A cold weather system moving into the Bay Area from the Gulf of Alaska is bringing frigid temperatures, rain, wind and the chance for snow above 2,000 feet this week, according to the National Weather Service.
Tuesday morning is expected to start out with temperatures that are up to 10 degrees below what they were Monday and lows Tuesday and Wednesday should hover in the mid 30s to low 40s.
As the week progresses, people can expect breezy winds, high surf along the coast and periods of moderate rainfall, with up to 2 inches of rain accumulating at lower elevations through Sunday, according to the Weather Service.
Most of the rain is expected to fall between Friday and Saturday and the cold system could drop snow levels to some ridgetops around the region, especially in the East Bay's Diablo Range and the Santa Lucias along the Central Coast.
