POWDER ALERT- SUNDAY-MONDAY CASCADES, TUESDAY-THURSDAY ROCKIES

Powderchasers.com

Happy early Thanksgiving everyone!  Eat your Turkey and start thinking about a blast of winter that will affect the Northwest, British Columbia, and eventually the Rockies early next week.  Arctic air will plunge down from Alaska late this weekend kicking off heavy snows over Whistler, Fernie, Kicking Horse, and the Cascades beginning on Sunday.  Snow levels in the Cascades will start out at 2,000 feet and plunge to just above sea level by Monday morning.   Deepest Period for chasing Powder will be Sunday Afternoon through Monday.   My picks for deep will include BC, Baker, Stevens, and Alpental with a convergence zone likely by Monday morning (12 inches plus). Northwest flow favors the central and north Cascades.

Models show most of the  Rockies setting up for snowfall next week.  Spokane area mountains (Idaho/WA border) do very well on Sunday night/Monday. Central Idaho (Sun Valley) Montana, and Wyoming (Tetons) set up nicely for Monday PM and Tuesday.  The Wasatch will see periods of moderate snow Tuesday-Thursday under NW flow.

Colorado could get deep by Wednesday or Thursday next week?  Steamboat and areas north could see snowfall as early as Tuesday.  Models show a possible moisture tap extending into Friday over much of Colorado (Stay tuned for updates).

Long term models show a repeat over the Cascades the following week (December 9th) with warmer air but plenty of moisture.
