We love avalanche pups, but Stevens Pass might take the headlines by late next week and beyond.

Moderate snow fell late yesterday and overnight in  the Cascades with Alpental(9 Fresh), edging out Stevens Pass (7 inches) and Mount Baker (5-7).   Moderate snow fell overnight in Montana with Bridger Bowl reporting  6 inches this morning.. Snow  just started over northern Wyoming as a cold front edges south  impacting Wyoming and Colorado with light snow today and tonight (2-4 Tetons).  Monday will be decent in Colorado from Summit County North into Steamboat but don’t expect anything other than a freshening (2-5).


The Sierra will finally get a decent dump Tuesday PM through Wednesday AM (9-14 inches) withMammoth and areas in South Lake seeing slightly higher amounts.  This migrates into Arizona late Tuesday night into Wednesday (9-14 for AZ Snowbowl) and into the 4 corners of UT/CO/NM by Wednesday mid morning. Moderate snow will fall over Durango, Wolf Creek, and Silvertonand heavier amounts possible over Taos for Wednesday late AM through early PM.

The Wasatch in Utah will see light snow on Wednesday AM turn moderate Wednesday afternoon through Thursday morning (8-12 Cottonwoods, 5-9 Park City, 6-10 Ogden North).

Northern Colorado along I-70 stands it’s best shot of snow from late Wednesday night into Thursday as winds shift to the NW taking left over moisture from the 4 corners through central and northern areas.  Amount might be moderate (4-7). Much of energy will be over the Northeast Plains by early Thursday. Models show residual moisture continuing through Saturday for Colorado. Expect freshenings Friday and Saturday.


Long range looks very exciting.  A stronger system slams into the Cascades late this week and migrates through IdahoTetons, and the Wasatch by Saturday morning. Heavy snow is likely with this event including all areas of Colorado Sunday-Tuesday (Week #2). 

The Cascades continue to see heavy snow during week #2 so expect chasing to be abundant for several days.
