Overview
|
A fast-moving winter storm swept through the Tri-State area on Saturday, December 6, 2025, leaving a blanket of heavy snow and leaving broken records in its wake. The storm's rapid intensity caused significant travel disruptions throughout the day across parts of South Dakota, Nebraska, Minnesota, and Iowa. The snowfall began shortly after daybreak across central South Dakota and Nebraska, gaining momentum as it tracked eastward. By the afternoon hours, weather observers reported snowfall rates of 1 to 2 inches per hour across eastern South Dakota and northwestern Iowa, quickly accumulating impressive totals. The bulk of the snow moved out and dissipated through the evening; however, the storm’s final act was a light freezing drizzle reported across the region overnight. After the storms exit, 2 to 8 inches of snow fell across the entire Tri-State region with some locally higher amounts. Sioux Falls Sets Century-Old RecordThe city of Sioux Falls, South Dakota set a new daily snowfall record. The total recorded accumulation of 4.9 inches surpassed the previous daily record of 2,5 inches, a mark that had stood since 1893. |
