We have issued a Winter Weather Advisory and Winter Storm Warning for the Sierra from Lassen County down through Mono County. Up to 3 feet of snow is expected in the highest elevations.
Thunderstorm activity is expected to decrease this afternoon due to more cloud cover. We still have a 10-25% chance for storms in the Sierra and northeast California through the early evening. Main hazards with any storm will be frequent lightning, small hail, gusty winds up to 45 mph and brief periods of heavy rain that could lead to some ponding in low-lying areas.
A Wind Advisory is in effect for Southern Lyon and Mineral counties from 2 PM this afternoon until 2 AM Sunday morning. The main area of concern will be along Highway 95 from Hawthorne to Schurz along Walker Lake.
