Another clipper system will slide southeast across the Dakotas today and bring another round of light snow to mainly western and central South Dakota. Accumulations will be around a half inch or less. This system will be weaker than the one that moved through on Monday, so winds will be lighter and blowing snow is not expected to become an issue. An arctic front will move south across the region this evening, following the low pressure system. Bitterly cold wind chills will return to much of the area late tonight through Wednesday morning. Wind chill advisories have been posted.
