The latest storm coming through the region will affect each area differently. For the valley, the wind (a High Wind Warning is in effect Thursday until 4 pm) will make the most impact, with maximum gusts possibly exceeding 70 mph in the exposed areas. Rain is likely through during the day, and it could turn to snow late Thursday, but I don’t expect to see a lot of valley accumulation. Snow showers continue off and on Friday and Saturday before another potent storm moves in Sunday, bringing wind, rain and snow by Monday morning.
In the mountains (a Winter Storm Warning is in effect Thursday into Friday morning), snow levels will start fairly high, lowering to 7,000’ by Thursday morning, and quickly dropping below lake level by midday. Snow amounts will vary greatly depending on elevation. The lake itself could see 6-12” of snow by Friday and the prime locations on the crests of the Sierra could see 1-2 feet, with more to come with the second storm Sunday. High winds will combine with the snow to create conditions that are likely to cause some closures over the mountain passes Thursday into Friday.
