9 AM MST, Sunday, February 17, 2019
Very cold temperatures are into southeastern Wyoming and western Nebraska now and will work their way into eastern Colorado and the Front Range region this afternoon. Temperatures this evening are expected to fall into the single digits along the urban corridor and probably only reach the 15-20 degree range Monday and Tuesday.
A big snowstorm is not expected, but rather and extended period (this evening through Tuesday) of mostly cloudy skies and periods of mainly light snow. There is not much moisture with this storm, but what moisture there is may convert into rather fluffy snow.
There will probably be some local accumulations around 6 inches by Tuesday in and near the foothills from Boulder County southward. Most areas will probably be under 6 inches. The chance for greater than 4 inches is about 20%. The most likely accumulations are:
2-4″ Boulder, Broomfield, Colorado Springs and metro Denver west of I-25 and south of I-70.
1-2″ northeast Denver, Longmont, Fort Collins, Cheyenne
Although the temperatures should be less cold Wednesday, it will likely be a cold week overall, with another chance for clouds and light snow late Thursday or Friday.
