Weather systems to produce snow and rain through the weekend

A series of storm systems will move into Lake Tahoe and the Sierra this weekend but how much snow to expect is still up in the air. The first low will move into the region late Thursday night into Friday, with moist flow continuing ahead of the next system for the weekend, according to the National Weather Service in Reno.
A weak cold front will shift through the region Sunday, followed by the next upper level low now situated off the coast of British Columbia. The weather service is confident these systems will bring rain and mountain snow to northeast California and the Sierra, but confidence is lower that much precipitation will make it into western Nevada.
Snow levels will be variable throughout the weekend and may range from 5,500 to 7,000 feet north of Interstate 80 and 6,500 to 8,000 feet south around Lake Tahoe. It is still uncertain how much snow and rain will be associated with the systems. Those with travel plans over the Sierra this weekend should prepare for winter driving conditions and check the latest forecasts for additional information.
