As we discussed in this week's State of the Atmosphere, there will be a chance for rain and snow this evening across northeast Colorado as a relatively weak cold front pushes through the region.
This will be a lower impact event. Models bring between ~0.02-0.12 inches of precipitation to Denver through Wednesday morning, which would translate to about an inch of snow if it all falls as frozen; however, temperatures will be marginal for snow, especially at the onset. Given that we expect any shower activity to be scattered in nature, we are forecasting little to no accumulation for most of the metro area, though a few locations could pick up a coating to inch of wet snow on colder surfaces. Any precipitation should exit the metro region by mid-morning Thursday.
Temperatures Thursday will be at least 15 degrees cooler than today, with highs topping out in the lower to mid 40s across the region.
Heavier snow is expected in the mountains and across the far eastern plains with this system. Totals through Thursday for much of the high country will be in the 6 to 12 inch range, with 1 to 3 inches possible near the Colorado / Kansas border.
Our next chance for precipitation after tonight/tomorrow AM will be late Saturday into Sunday, when another weak cold front swings through.
