An upper level disturbance is predicted to drop southward through Colorado Sunday...keeping the weather picture unsettled for the end of the weekend. Snow is expected to develop in the afternoon and through the evening over the mountains and across the eastern plains...although the best chances for precipitation will be along the I-25 corridor...with lighter winds and snow accumulations than Saturday's weather. Temperatures will stay well below average across the viewing area. (Please visit http://weather.gov/pub for more information.)
