A series of weather systems will start moving through the Sierra and western Nevada on Thursday and continue into the holiday weekend, the National Weather Service said, but the overall impact is hard to forecast.
The first storm, Thursday into Friday, looks to bring gusty west-southwest winds and chances for Sierra snow and western Nevada valley rain, the NWS said on its website (weather.gov). The second, Saturday into Sunday, is likely to bring another round of gusty winds and wintry precipitation with better chances for snow at all elevations.
“For Thursday into Friday, while we have medium to high confidence of a moderate storm, snow levels at onset and the area of greatest impact have yet to be determined,” the NWS said in a special weather statement.
“The strength and track of the weekend storm remains widely variable from a solid if not major storm to something fairly weak. Snow levels are also more variable with some accumulating snow on the valley floors possible.
“If you are planning to travel for the holiday weekend, prepare for winter driving conditions and delays with emphasis on the Sierra passes. Monitor the forecast and think about the possibility of altering your plans, especially as the forecast becomes clearer,” the NWS concluded.
