A wintry mix of precipitation will spread across parts of the region overnight as a fast moving disturbance spins into the Northern Plains. Toward midnight a mix of rain, freezing rain and sleet is expected to develop across south central South Dakota and move northeast into the area. Temperatures will be cold enough at the surface for a thin glaze of ice to develop on untreated roads, sidewalks, and other exposed surfaces. Most of the precipitation will change over to light snow after 2 am with around an inch of accumulation possible along the Interstate 29 corridor, with 1 to 2 inches of new snow across northwest Iowa and southwest Minnesota. As a result, a Winter Weather Advisory is in effect for parts of the region through 6 am Monday morning.
