As we predicted last week low pressure is going to impact many areas of the West over the next 48 hours with the main core of the snow affecting the 4 corners of Colorado, southern and central Utah,as well as along I-70 in Colorado late in the storm (Saturday) especially at the highest elevations. There is very little cold air to work with until late in the storm cycle so expect snow to start out around 10,000 feet and lower to 8,000 by Saturday morning. The San Juan’s of Colorado should see 5-9 inches of wet snow especially Wolf Creek Pass under SW flow and perhaps the highest peaks around Crested Butte and Silverton! The winds shift to the West on Saturday shutting down precipitation in the South and centering snow bands around Vail Pass, Beaver Creek, and up into the Flat Tops near Craig. By this time the moisture will be limited so expect 4-6 inches at higher elevations. Snow will continue in Central and Northern Colorado until mid morning on Saturday. The Wasatch of Utah should see snow from I-80 South (Little and Big Cottonwood Canyon) and only at areas above 8,000 feet (4-7 inches possible by Saturday morning at the peaks). Areas around Park City will see mainly rain and areas to the north like Snowbasin and Powder Mountain will see lesser amounts.
The Northwest and BC dives into a very wet pattern beginning in earnest on Saturday and continuing through Monday with 3-5 inches of rain and 10,000 foot snow levels through the period. No real snow is expected however if that were a cold storm would equal roughly 3-4 feet of snow in 2 days. This is what the Northwest is all about and hopefully in a week we can call for snow up there!
Extended: Light snow possible near the UT/WY border on Monday with a trend towards warm and dry for most of next week! The next chance for snow over the Rockies looks to come around October 22nd with colder air so stay tuned for further reports on Powderchasers.
