Cooler air will start to move into the Front Range region on Friday, and then colder with clouds and some snow Friday night and Saturday.
Most probably accumulations:
3-6 inches lower foothills and plains (maybe a little less on the high plains east of Denver).
6-10 inches mountain areas, heaviest north I-70.
Timing:
Northern Colorado mountains and Cheyenne area may see the first accumulating snow late afternoon or early evening Friday.
Lower foothills and plains (Denver-Boulder) probably won’t see the first snow until after dark Friday evening.
Uncertainty about heavier snow:
The storm will become stronger as it moves east-southeast across Colorado and into Kansas/Oklahoma. If the intensification occurs a little sooner, the potential for somewhat heavier snow goes up. That appears to be an unlikely scenario at this time. I will update tomorrow.
