Powder Alert in September?  Double digit snowfall totals are rare in September (1965 Wyoming storm had 20 inches plus).  The next storm is impacting the Northwest (5K-6K snow levels) at upper elevations and will impact the northern Rockies with highlights in Montana, Wyoming, Idaho, and Utah.   Snow will break out in the Tetons (8500 feet) and Wasatch (7800 feet)  early Wednesday and intensify through the day.  Heavier snow is likely over central and southern Montana where a direct hit is likely over Bozeman. Some areas of Montana from Missoula and south will see 9-14 inches  above 8,000 feet.  Snow will continue in waves through the week.  The coldest portion of the storm hits the Central Rockies Friday with the Wasatch seeing snow to mid Little Cottonwood and perhaps Park City Valleys. Lake Effect snowfall is possible in the Wasatch on Friday (Rare event for September).   If this were mid winter my chase would include Grand Targhee and area’s North into Montana on Thursday and perhaps the Wasatch on Friday.

The Sierra remains just south of the action with areas north of Highway 50 seeing light snow.  Colorado stays out of the main action until Thursday or Friday.  Friday will see colder temps and perhaps accumulating snowfall over Rabbit Ears pass and areas north of I-70.  Leftovers should accumulate with the cold front and a guess of 5-9 inches above 8,000 feet. The Divide near Loveland might benefit with the cold air alone!

The extended POW cast looks very wet for the Northwest, BC and the Gulf of Alaska. with periods of rain and snow (7,000 foot snow levels) through Monday. Higher peaks near Mount Baker and British Columbia should fare well!

Stay tuned to for the latest POWCAST. I cant believe it is only September and we are looking at double digit snowfall totals.   Rumor has it that Silverton mountain in Colorado grabbed 1-2 feet at isolated areas of the summit last week.
