Snow for the evening commute

10:00 AM, Thursday, January 12, 2017

A weak frontal passage this afternoon is likely to increase clouds and drop the temperature a bit from Denver northward. Most indications over the last few days are for no precipitation in the lower foothills and plains. But this morning’s runs of some local scale models (like the HRRR) suggest a period of snow (even some brief moderate or heavy intensity) likely in the Denver-Boulder-Fort Collins corridor following the wind shift to east-northeast. Model forecast accumulations are relatively minor (1-4″) but the timing would make the afternoon/evening commute messy. Given these latest models (and my underforecasting bias in a couple recent snowfalls) I’d say snow is likely this afternoon/evening in the Denver-Boulder-Fort Collins area, but much less less likely in Colorado Springs.

 

The holiday weekend is likely to bring relatively tranquil weather Friday and Saturday, but a storm passing to the south and east of Colorado will likely bring winter precipitation to southern Colorado and the eastern border areas late Sunday and Monday. For the Front Range from Denver northward the impact of that late weekend storm is less certain, but it appears not to be a significant weather maker at this time.
