Cold, wet weather to come by week's end

After Southern California got a spritz of rain and snow over the weekend, a chilly and wet system is due to arrive in the northern part of the state by week's end, perhaps ushering in what at least one National Weather Service forecaster predicts will be a wet March.

From the weather service:
Cold and Wet System for the End of the Week

Impacts

Snow down to as low as 3500 feet may cause mountain travel difficulties Fri into the weekend
Locally heavy rain from thunderstorms Friday and Saturday afternoons may cause travel delays

Forecast Confidence
Medium for patchy frost late tonight into early Tuesday
Medium for lowering snow levels and moderate snow accumulations
Medium for thunderstorms Friday and Saturday afternoons

Timing and Strength
Freezing temperatures and frost possible in the Valley and lower foothills late Monday night into early Tuesday morning
Wet weather Friday through the weekend. Heaviest rain/snow late Friday through Saturday
Snow levels ~5500 feet Friday, lowering to as low as 3500 feet for the weekend, with the possibility of moderate snow accumulations above 5500 feet

Weather Summary
Breezy winds will decrease tonight allowing temperatures around freezing temperatures and frost to develop in portions of the Valley and lower foothills. Milder low temperatures expected for mid week, with dry weather. A wet and cold system will begin spreading into the area Thursday night, with precipitation becoming widespread on Friday.
