It will be a very active weather week ahead as a series of winter storms move through the region through the Thanksgiving weekend. A Winter Weather Advisory is in effect Tuesday night into Wednesday morning for the mountains. Snow levels will likely fall to near valley floor level Wednesday morning, though it is doubtful there will be any lower valley accumulations. In the mountains, snow accumulations could be anywhere from a couple of inches at Lake level, while the passes could see 6-8 inches by Wednesday afternoon.
Things should clear up Wednesday night through Friday morning, and then a series of storms come through almost on a daily basis through Monday. In terms of travel windows, late Wednesday through Friday morning should yield conditions over the mountains, and fast moving systems through the weekend will make for a wait and see situation, as the timing of each front gets tough this far out. These storms will be cold enough to bring snow levels down to or near valley floors through Monday, although again it is unlikely there will be any significant accumulations below the foothills.
