November 12, 1993:

A winter storm moved through the area on November 12th and 13th. A wintry mixture of precipitation in the form of freezing rain, sleet, and snow began during the afternoon on the 12th in western portions of Minnesota, while heavy snow fell in a swath from southwest South Dakota through central and northeast parts of the state, with generally four to eight inches reported. The snow was also preceded by freezing rain in south central South Dakota. Significant accumulation of ice occurred within about a 70-mile wide area from west central Minnesota into the Arrowhead region. Up to five inches of snow fell on top of the ice, making travel extremely hazardous. In South Dakota, locally heavier snowfall amounts included 12 inches at Midland and 10 inches central Hughes County. Several schools and other community events were closed due to the ice and snow. In south central South Dakota, trees were damaged by heavy ice, some of which fell on power lines, causing outage. Other snowfall amounts include; 8.0 inches in Blunt; 7.0 inches in Murdo and near Victor; and 6.0 inches near Onida, Faulkton, Highmore, and Leola.
