That likely means snow at higher elevations and could even bring snow to downtown San Francisco.

It hasn’t snowed in downtown San Francisco since 1976, according to National Weather Service Meteorologist Austin Cross.

The Bay Area has already seen snow on some of its mountain peaks after a storm last week.
