Here we go! A series of strong storms will impact the Tetons each day from Thu (Dec 26) to Mon (Dec 30) with five-day snow totals ranging from 2-4+ feet above 8,000 feet. Many valley areas will pick up 1-2 feet. Snow will be medium density on Thu-Fri, then will trend high density/upside down Sat-Sun as warm air arrives. Colder air & more powdery snow will arrive Sun night into Mon.

An active pattern is setting up across the West for the holiday season with heavy snow for the Northwest in particular. Utah & Colorado will see frequent shots of light to moderate snow, while California and Oregon resorts will see both rain and snow with warmer air creeping in. The East will see a quiet pattern with a gradual warming trend, then colder air will arrive after the New Year.

On Wednesday and Thursday, a potent storm is headed for the BC coast and will slam the PNW with several feet of snow, strong winds, and rising snow levels. There are many red flags. The Rockies grab heavier snow from Friday to Sunday.

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.
