CHASE NORTH FROM THE CASCADES THROUGH THE NORTHERN ROCKIES FOR POWDER THIS WEEK. 1-2 FEET IS POSSIBLE THROUGH SATURDAY
Summary 12/26/17- AM report
The perfect storm bringing a White Xmas to the metro areas of the Pacific Northwest to New England. Ski resorts all recorded decent snowfalls including a monster dump at Eldora Ski area just outside Boulder Colorado where 24 inches has fallen in the past 2 days! The Tetons will continue to score snow almost every day this week (Light) with a new system due for the Cascades on Thursday. That will swing over the northern Rockies late this week with some chase opportunities in many resorts. Snow will increase towards the end of the week in many areas of the northern Rockies.
Short Term Forecast
Santa had the ultimate chase this week from Seattle to Boston grabbing faceshots along the way over the Tetons, Summit County Colorado, extending through the Midwest to northern Maine. This week scores some powder opportunities in the Cascades, Montana, Panhandle of Idaho and the Tetons. Warmer air will accompany these systems so the snow levels will rise in most areas this week.

Light snow will continue in Wyoming (Resorts scored a foot of powder for XMAS) and pick up slightly Wednesday/Thursday. Expect 1-3 inches each day with perhaps 4-7 inches Wednesday AM through Thursday morning. Ride late Wednesday or early Thursday for the deepest event (No single double digits). Snow will increase again Friday PM/Saturday AM.
The Cascades are back in the highlight for moderate to heavy snow Wednesday night /Thursday that could land a foot of powder for Stevens Pass, Baker, and perhaps Alpental (upper elevations). The snow level will be at pass levels with some warming noted on models (Medium to high density snow) by Friday. The highest snow totals will be found Thursday morning at many resorts with a focus in spots further north. The southern Cascades near Crystal including northern Oregon may initially see lower amounts until late Thursday/Friday when snow will increase (moderate) further south. Expect 12-18 inches at many central or northern Cascade resorts late this week. Snow levels will be creeping higher with rain just below the bases.
Attention turns to the Panhandle of Idaho, Wyoming, and Montana in the Rockies. Moderate to heavy snow is likely in Idaho just south of Interstate 90 extending east to the central portions of the State. Montana Snowbowl may score a moderate dump Thursday-Friday (1st chair Friday or last chair Thursday) including many spots in the southern Panhandle. Areas north towards Schweitzer will see lighter amounts (3-7).
The Tetons continue to reap a direct hit of moisture this week. Snow will increase somewhat on Wednesday (2-4) and again on Friday-Saturday. Expect 6-12 inches of additional snow this week in the Tetons especially late Friday/Saturday (Your highest odds of boot high or more). There may not be any single double digit dump but a continuous light or moderate refresh this entire week. Montana is on the wildcard list for light snow leftovers towards the end of this week. Higher amounts are likely near Red Mountain Lodge just above the Wyoming border. Models also hint at significantly higher amounts of snow in Wyoming east of the Tetons in the Wind River Range this week (backcountry).
Most moisture this week appears to stay north of resorts in Colorado and Utah however some light snow is likely over northern portions of these regions.
Below: Total snowfall through Saturday morning in the west.
The extended models into the New Year (Early next week) demonstrate low confidence for significant storms for the west. Long range ensembles show an increased chance of snowfall during the 2nd week of January but it’s too far out for confidence.
Below: January 1st ensembles showing decreased chances of snowfall for the west
The long range ensembles for the 2nd week of January show a bit more optimism.
Hope you all had a great holiday! See you on the slopes soon as I mend a partially torn ACL and PCL from a few weeks ago mountain biking near Boulder. That might not keep me off the slopes for a foot of powder if it falls somewhere overnight this week? Powderchaser Steve- Lead Forecaster
