Enjoy the sunshine while you can. The ridge of high pressure will keep our skies clear through Thursday before allowing some high cloudiness to creep back through the region on Friday. Temperatures will be near seasonal norms in the mid-50s through the rest of the work week. On Saturday, a cold front approaches kicking up some gusty valley winds, and the mountains will likely see some snowfall by late in the day. We will be shadowed out in the valley initially, but by Sunday, valley snow becomes a pretty good bet. Amounts are tough to calculate because of the expected shadowing, but the west side of the valley could see some accumulation, and the foothills could potentially see several inches. Travel over the passes could also get difficult due to high winds and snowfall limiting visibility. Total snow accumulation for the mountains could be in the 102 foot range on the crests, with lesser amounts for the lake communities. Valley temperatures will fall from the 50s Saturday to the lower 40s Sunday, and will take a few days recover back to the lower 50s.
