Cloudy and windy today with a chance of light snow by afternoon

A low pressure system moving into the Pacific northwest will shift the storm track or jet stream over Northern California today.

Look for increasing clouds and southwest winds 20 to 30 mph in the afternoon with local gusts to 45 mph at lake level and up to 80 mph along the Sierra crest.

Highs today are forecast to reach the mid 40s this afternoon under mostly cloudy skies. Light snow could fall as early as this afternoon but more likely this evening as a frontal system pushes across the area.

Current computer models suggest around an inch or snow could fall at lake level with around 2 to 4 inches at the upper elevations by Saturday morning. Lows tonight are expected to drop into the lower and mid 20s under partly cloudy skies.

A broad upper level trough of low pressure will remain over the area through the weekend resulting in partly cloudy and cool conditions both Saturday and Sunday. Cooler air aloft may provide enough instability for an isolated snow shower Saturday afternoon.

Daytime temperatures are forecast to reach the mid 40s at lake level this weekend with lows in the teens to lower 20s. These temperatures are about 5 degrees below the seasonal normals for late March.
