The agency posted the following on it's website:

Conditions will change rather quickly during the course of the day Tuesday. The rain is expected to change over to snow during the afternoon across areas west of I-25 and the remainder of southeast Wyoming and the Nebraska panhandle by Tuesday evening. Snowfall amounts will be highest along the Pine Ridge and Cheyenne Ridge where two to four inches will be possible. Otherwise, amounts will generally be less than a couple of inches, but will be accompanied by strong north winds gusting at 35 to 45 mph Tuesday evening which will cause some blowing and drifting snow.

The agency issued a weather statement which includes the following:
