A clipper will bring the mild air of Thursday to a halt. As it moves through, north central and northeast South Dakota has a chance for freezing drizzle and freezing rain tonight into Friday. Freezing Rain Advisories are already in effect for Big Stone, Traverse, Brown, Clark, Codington, Day, Deuel, Edmunds, Grant, Hamlin, Marshall, McPherson, and Roberts Counties starting at midnight tonight through Friday at noon. Lows will fall to the twenties and thirties tonight.
After the slick commute in north central and northeast KELOLAND Friday morning, much cooler air will pour in via north winds. Highs will be at least ten degrees cooler in northern South Dakota, to about five to ten degrees cooler in southern KELOLAND. The cooling trend will continue for the weekend with highs in the twenties and thirties in central and eastern South Dakota to the forties in the west.
Another clipper will travel through the upper plains this weekend. It will bring another round of rain and snow to KELOLAND. The best chance for the wintry mix will be Sunday night into Monday in northern South Dakota. After the clipper rolls through, temperatures will remain below average for at least the first half of next week in eastern KELOLAND.
