The National Weather Service has issued a snow advisory for the Mother Lode from late Tuesday night through Wednesday morning.
A strong cold front is expected to hit the region late today. Forecasters are predicting periods of rain and snow overnight with snow levels lowering into the 1,000-to-2,000-foot range Wednesday morning.
The rain and snow will taper to showers by Wednesday afternoon with snow levels rising back to around 3,000 feet. Total snow accumulations of 2-to-4 inches are expected above 2,000 feet.
Temperatures are expected to remain quite chilly for this time of year. The potential for significant snowfall over the Sierra Nevada tonight and Wednesday morning could see around a foot of new snowfall in the higher elevations, says the weather service.
Rain and snow is expected to develop near Yosemite around midnight to 2 a.m., spreading by early morning to most of the Sierra. Total snow accumulations of about 2-to 6-inches are forecasted at Yosemite National Park, with lower amounts further south.
Persons planning on driving into the Sierra Nevada should keep abreast of the latest forecasts and weather conditions. Be prepared for the possibility of hazardous, winter-like travel conditions, and carry chains as needed.
