The National Weather Service has issued a Winter Storm Watch for the Sierra Nevada above 5,000 feet, which is in effect from late tonight through Saturday afternoon.
The moist Pacific Storm System will consist of a couple of waves of moisture.
The first wave will move into Northern California late tonight through tomorrow, bringing high elevation snowfall to the Sierra. Snow levels with this first wave will begin around 7,000 feet before gradually lowering.
The second wave is forecast to move through Northern California on Saturday. This system will bring even more snow to the Sierra, with snowfall down to as low as 4,000 feet.
Total snow accumulations above 5,000 feet will range from half a foot to four feet.
Winds of twenty-five to thirty-five mph are expected with gusts up to fifty mph.
A Winter Storm Watch means there is a potential for significant snow accumulations that may impact travel. Travel difficulties over the Sierra range will be likely so carry tire chains and extra supplies.
