Tomer’s Take: The current storm cycle ends with one final cold front that hits Colorado with the coldest air of the season and 8-24″ of snow accumulation. Strong jet dynamics and temperature efficiency will help generate the snow.
Colorado mountain temps dip below zero late 10/29 into 10/30.
Wyoming mountain temps dip below zero 10/28, 10/29, and 10/30.
Montana mountain temps dip below zero 10/27, 10/28, and 10/29.
