A storm dropping snow over the Intermountain on Wednesday and Thursday will shift east of the southern Rockies on Thursday night and Friday. In so doing, it will trigger heavy wet snow east of the Rockies along the I-25 corridor from southeastern Wyoming to south-central Colorado.

In Denver, heavy wet snow whipped by strong winds will pile up 8-12 inches deep through Friday evening. Snowfall will be twice as high along the nearby foothills.

The heavy wet snow will cling to trees and powerlines triggering electrical blackouts. Snow and blowing snow will make for very tough driving and road closures will be possible.
