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.

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!
