Most areas in the Tetons picked up 9-11 inches of new snow, most of which fell after the cold front moved through on Sun afternoon so snow quality will be drier and more powdery on Monday. Snow will continue Mon AM with WNW winds favoring Targhee for additional snowfall. Light snow showers are also possible Tue, then 2-3 more storms will arrive Wed (Jan 1) to Sun (Jan 5).

As of Monday morning, the cold front had moved into most areas, with general snow totals in the 7-14 inch range from the PNW into Idaho, Wyoming, Utah, and Colorado. Additional waves of energy focus on the Cascade Ranges of Oregon, which will eventually push north into Washington Midweek. The Rockies grab the leftovers. Both midweek and late week have the highest odds. The Sierra is a wildcard.

An active pattern will continue this week with frequent storms bringing heavy snow to the Cascades and Northern Rockies. A similar pattern may continue into next week as well. Sustained cold will reach the East after New Year's with increasing snowfall potential over the next 1-2 weeks.

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.
