There are three storms to watch. The initial phase hits the Sierra Thursday with moderate, decent-quality powder. The second surge of moisture brings in warmer, windier, and deeper snow for the Sierra on Saturday. The PNW and BC will grab heavy snowfall, favoring the north. Central Idaho, the Wasatch, and the Tetons should nab 5-11 inches this weekend, initially warm, followed by cooling.

The West will see some welcome snow late this week and into the weekend after a drier start to December. A weak storm will move through on Thursday followed by a stronger storm Friday-Sunday. The Sierra (including Tahoe), Cascades, BC, and Northern Rockies will be favored for the deepest snow totals. The East will see rain & some snow Wed-Thu & again early next week with a warmer airmass in place.

A storm will track through the Mid-Atlantic Wednesday and bring rain to the eastern half of the Mid-Atlantic. The western half of the Mid-Atlantic will see rain change to snow with variable snow accumulations depending on elevation and location. Further western areas will see more snow with 1-6 inches expected. Lake effect snow occurs around the Great Lakes Thursday and Friday with 6-24 inches.
