A strong jet stream and cold, moist air (marked by speckled clouds) are poised off the Pacific Northwest coast and prepared to dive toward Colorado starting Tuesday night.
NWS says 6 to 12 inches of snow possible across the high country of Colorado Tuesday night

SUMMIT COUNTY — A winter storm watch is in effect starting Tuesday evening for most of Colorado’s north-central mountains and the northeastern plains. A strong and winter-like trough digging down out of the northwest is forecast to reach the I-70 corridor late Tuesday, bringing periods of heavy snow — up to 1 to 2 inches per hour — during the night.
Monday looks to be the warmest and driest day of the week, with high pressure ahead of the storm raising temps all the way to the upper 40s. For the rest of the week, look for highs in the 30s, with overnight lows in the teens.
Total snowfall amounts of 6 to 12 inches are possible before the storm moves out of the mountains Wednesday morning, transitioning to an upslope event for northeasten Colorado. According to the National Weather Service, the northern mountains and northern Front Range will once again be the main target, as moisture looks more limited in the central and southern part of the state.
High pressure returns briefly on Thursday, but a progressive storm track could bring yet another system to the area starting Friday evening, with models showing a big trough developing over the Great Basin. This system could start out with a southwest flow more favorable to the central mountains, so Aspen, Crested Butte and Vail could see their share of precipitation during the first part of the weekend.
As the storm moves over Colorado, flow is projected to be moist and out of the northwest, bringing a good chance of snow to the northwestern quadrant of the state.
