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.

An active pattern is setting up for the Sierra Range, with one moderate cold storm on Thursday and a wetter but warmer storm due Friday PM/Saturday. Moisture streams north into the Pacific Northwest and BC, with some decent totals later this weekend. Leftovers favor Idaho and Wyoming, as most moisture stays north of Utah and Colorado, which grab lower totals. The extended has some hope!
