Tomer’s Take: A three storm combo remains in my forecast through 12/12 with heavy grand totals across the West. A forth storm system is possible on 12/13-12/14.
- Storm #1 is moving at snails pace and continues pushing snow into the Sierra and also interior Rockies of UT, WY, and CO through 12/7.
- Storm #1 has a few bullseyes in the Colorado including Crested Butte, Vail, Steamboat, Wolf Creek, Silverton, and Purgatory.
- Storm #2 12/8-12/9 is trending weaker especially for CA, UT, WY, CO.
- Storm #3 12/10-12/12 is stronger and colder.
- Alta and Snowbird are reporting 8-9 inches in the last 24 hours. Jackson Hole is reporting 6 inches in the last 24 hours.
- Mammoth Mountain is reporting 5.5 feet of snow so far this December.
Snow is also falling in Colorado where it’s just getting started. A 3.5 day prolonged period of focused snow is in my forecast with over a foot for a few locations.
