A large upper level storm system to our west and cold surface high pressure moving south out of Canada should combine to bring cold weather and significant snowfall to the Front Range and eastern Colorado beginning as early as Friday evening. The risk of snow extends through the weekend, but right now it appears that the best potential for heavy snow in the Denver-Boulder area is Friday night through Saturday morning.

There is still uncertainty in the details, but here are some of the things I am fairly confident about now.

1. A widespread snowfall of at least 6 inches, local areas much more, is appearing likely for the Colorado Front Range and adjacent plains Friday night into Saturday.

2. There is less potential for heavy snow in Wyoming and in western Colorado.

3. Additional snowy periods are likely Saturday night through Monday morning, but probably becoming more focused with time in southern Colorado and northern New Mexico.
