Some snow Tuesday night; worse out on plains

3:20 PM MST, Monday, November 9, 2015

A vigorous storm system Tuesday night into early Wednesday will likely bring some bring brief heavy snow and high winds to some parts of northeastern Colorado and southeastern Wyoming. But it appears that the storm won’t really get its act together until it is mostly east of the Front Range urban corridor. So a high-impact storm along the immediate Front Range is possible but not highly likely.

Unlike the ideal storm track for Front Range snow fans, which would be across southern Colorado, this storm is likely to intensify near and to the immediate east of Denver. That should result in north-northwest winds developing along the foothills south of Larimer County, not ideal for prolonged snow. Farther east a convergence between northwest winds along the immediate Front Range and northeast winds on the plains could lead to more serious snow and blowing snow. DIA could get worse conditions than areas closer to the foothills.

Most likely amounts Tuesday night -Wed morning (maybe starting as rain late Tuesday):

Denver-Boulder-Fort Collins: 2-5 inches (the heavier end of the range more likely from DIA arcing northwest up toward Fort Collins; the lower end of the range more likely in Boulder and Jefferson counties).

Cheyenne, Nederland: 4-6 inches (and windy in Cheyenne)

Colorado Springs: 0-1 inch

High plains east of Denver and I-25 north of Fort Collins: considerable blowing snow late Tue and early Wed
