For the Cheyenne area, a Winter Weather Advisory is in effect from 5:00 PM Saturday until 5:00 PM Sunday. The main threats with this system are expected to be one to three inches of snow combining with winds gusting up to 60 miles per hour causing blowing and drifting snow.

A High Wind Warning is also in effect until 11:00 PM Saturday for much of south-central Wyoming. Winda out of the west at 35 to 45 MPH with gusts up to 65 MPH are expected Saturday afternoon and evening.
