With cold air still in place near the surface, any rain that falls across the region will freeze on contact. Very hazardous road conditions will result as the ice builds up over the course of the day. Sleet and freezing rain will also spread eastward toward Sioux Falls and Bismarck later in the day.
By tonight, the storm system will begin to emerge in the Plains. Freezing rain will spread across the rest of the Dakotas into parts of Minnesota and Iowa.
Some places will receive between one quarter and one half an inch of ice, which is more than enough to bring down trees and power lines.
