The southern half of South Dakota is under a Winter Storm Warning for today into Wednesday. Due to a slight southerly shift of the track of the storm, activity is delayed from earlier projections. Greg Richards is with the National Weather Service in Rapid City.
According to Mike Gillispie with the National Weather Service in Sioux Falls, snow is expected to fall heavily in the east from mid-morning through the day.
