A weak storm system will bring some clouds, gusty winds and perhaps an early Friday morning shower to the region, although the mountains should block most if not all of the precipitation before it gets down into the valley. Temperatures will drop to the lower 50s after hitting a record high in the 60s today. The front passes quickly, and the weekend should be dry with seasonable temperatures.
The next storm system moves in on Monday, with the heaviest precipitation Monday night into Christmas morning. Snow levels will start out at or above Lake Tahoe and could drop to the valley floor by Christmas morning, but the odds are that you will have to be in the foothills at least before you get any real accumulation. So while a White Christmas isn’t out of the question, your odds improve the higher you go.
