The Valley could experience showers and thunderstorms Saturday.
The two storms are are expected to drop up to an inch of rain in parts of the Valley, with the snow level falling to between 5,000 and 6,000 feet elevation in the Sierra.
A winter storm warning in the Sierra is in effect from 8 p.m. today through 4 p.m. Saturday, Bean said.
