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!

This past weekend’s fickle storm system dropped 6” of wet snow at Lookout Pass, with 4” at the summit of Whitefish, and 2” at Discovery and Lost Trail. This same storm system rolled into SW Montana overnight Sunday, with Big Sky reporting 3 to 8" as of 7AM Monday. Big Sky could add another few inches on Monday. High-pressure then reigns through Thursday. Snow returns Friday and into the weekend.

Thanks for reading this summer! For the rest of this week, a cold front moving across the Central Rockies will bring showers & t-storms to WY, CO, & NM Wed-Thu while the West Coast states will see a late-season heat wave. Next week, isolated to scattered showers & t-storms develop across the West with continued mild temps. Heading into mid-month, the PNW will trend wetter and cooler.
