Chases might be decent in the PNW and Canada this weekend, with moisture decaying as it moves into Idaho/Montana and Colorado by Sunday. Warm air initially in the PNW will push snow levels very high, followed by a strong cold front on Saturday. Deep snow is possible in the PNW or summits in BC.

The dry and sunny weather will continue through Sunday. On Monday, a cold storm will bring 1-5 inches of snow to many mountains, with cold air and snow showers continuing into Tuesday. Then the rest of next week should be dry, with another chance for snow around December 14-16.

A favorable pattern will remain in place across the East with cold temperatures, and a storm will also bring widespread moderate snow to New England. A storm will move into the West over the weekend and into early next week with snow favoring the Northwest and the Rockies, though some parts of the Northwest will see predominantly rain with warmer air in place.

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.
