Tomer’s Take: We’re heading into a much quieter period for the Intermountain West with one exception. An area of low pressure develops in Southern Colorado and Northern New Mexico 12/13-12/14 with moderate to heavy accumulation.
New snow at Steamboat, CO in the last 48 hours. Steamboat is benefiting from a dirty NNW flow out of WY.
