COLORADO IS BACK IN THE SPOTLIGHT FOR DOUBLE DIGITS FOR THE 4 CORNERS EARLY THIS WEEK. ADDITIONAL SNOW WILL RIPPLE IN FROM THE NORTHWEST MID TO LATE WEEK WITH A HINT OF A BETTER PATTERN CHANGE IN THE EXTENDED FORECAST
Summary 2/11/18 AM
Congratulations to Red Gerard on winning America’s first gold medal at the 2018 Olympics (Men’s Slopestyle). At just 17, he’s the youngest kid to medal in an Olympic event since the 1920’s. That was one heck of a run! He missed out on 10 inches of pow in his home town in Summit County yesterday, but I am sure he could care less since he taking home the gold! Stay tuned for a celebration event in Colorado!
The past storm performed as expected with the highest amounts found over Snowmass (16″ in 24 hours) which exceeded my original expectations. Telluride scored 6 inches during the day on Saturday with 5 overnight, so if you chased south you would have scored double powder days as suggested. The I-70 corridor generally saw 8-10 inches where areas north saw slightly lower amounts (originally forecasted higher amounts north). We chased to Eldora where 6-8 inches fell prior to 10 AM making for really good light density pow on 1st chairs Saturday. Elsewhere, in Colorado along I-70 snow began falling heavily by 9 AM and continued through early afternoon (6-10 inches in 5-6 hours). The San Juan mountains and to some extent Aspen nabbed snow later providing afternoon powder and early AM powder this morning. Cold air really increased snow totals as hinted on our last post where some resorts would approach double digits. The week ahead looks deep for the southern San Juan Mountains that really need a big dump!
Short Term Forecast
Light snow will be falling over the Wasatch tonight and Monday (2-4) from a splitting trough moving into California. The Sierra who has been shut out in the past few weeks will see moderate amounts favoring the southern zones near Mammoth (3-7). Elsewhere it’s a tease with lighter amounts. That system splits light snow for the Wasatch Mountains of Utah and moderate snow for northern Arizona and the southern San Juan Mountains. It will be snowing over Wolf Creek by Monday morning increasing through the day. Expect last chair to be fun with 3-7 inches and another 3-7 inches Monday night. Total snowfall should exceed 12 inches by late Tuesday morning. Areas further north will see lower amounts (Purgatory could be decent Tuesday) with 5-7 inches at Telluride who does best with NW wind direction as in the last storm. Silverton may also be in scoring position with 10 inches or more. The further south or east you travel will see the highest amounts.

The middle of the week will feature a moderate dump for coastal and interior BC. The northern Cascades (Baker is favored). That system works into the the northern Rockies and spreads moderate snow to many areas by Thursday. The Panhandle of Idaho, Tetons, Montana, Utah, and Colorado will all score moderate snow late Wednesday or Thursday. Its a bit far out to predict amounts but models seem to hold up decent amounts in Coastal or interior BC, northern Cascades, and eventually moderate dumps for a wide area of the Rockies.

Looking out towards next weekend its likely another system move into coastal BC and keep things active. The long term ensembles show we may be entering an active pattern towards the 3rd and 4th week of February. Its likely, the high pressure ridge that has kept snow away from the Sierra and will break down and open up a door for additional snowfall extending into the Rockies.
