| Episode Narrative | Widespread moderate to heavy precipitation fell as heavy snow over the northern and western part of the area, and as freezing rain and sleet in far southeast South Dakota. Up to 12 1/2 inches of snow and up to a half inch of glaze from freezing rain were reported in places, with over an inch of sleet accumulation in some areas. |
| Event Narrative | Snowfall of 6 to 11 inches, including 10 inches at White Lake, severely limited travel and commerce, with some roads becoming blocked. Winds averaging 20 to 30 mph contributed to the problems by causing drifting snow and areas of reduced visibilities in blowing snow. The snow was mixed with sleet and freezing rain at the start of the storm. |
