Moisture will overspread the Sierra Wednesday night, with moderate totals and colder temperatures. A stronger storm with a warm front will bring double digits to the Sierra, Pacific Northwest, western BC, and a few spots in the Rockies.

A ridge resides over the Rockies through Thursday. A weak system brushes the region on Thurs PM – Fri with scant, if any, accumulations. Our next Pacific storm arrives on Saturday, bringing chances of daily light flurries through Sunday. Light accumulations of 1 – 5 cm are possible each day. Chances for light accumulations return, possibly around the middle of next week. Colder too.

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.
