A cold Pacific storm will sweep across the state this weekend, potentially delivering up to two feet of snow in the San Juans, with up to 12 inches possible across many mountain areas. The best moisture appears to be associated with the approaching cold front, so the heaviest snow amounts look to be in areas favored by southwest flow, including the San Juans, the Steamboat area, the West Elks and the Flatttops, but the I-70 corridor won’t get completely skunked.

SUMMIT COUNTY — The Colorado high country could finally see a week of cold and stormy weather as the jet stream sets up in a pattern favorable to the northern mountains, bringing a series of hard-to-time weather disturbances into the area through the end of the coming week.

The big ridge of high pressure that shoved early seasons storms north and south of Colorado is gone for, and the subtropical jet stream and polar jet stream are converging over Colorado to fuel what could be the biggest storm of the season so far. Continue reading
