The episode as NWS FSD wrote it up.
Rain, freezing rain, and snow spread into southeast South Dakota late Friday December 29th and early Saturday December 30th. Significant accumulations of snow and ice were reported in the area near and between the James and Missouri Rivers before the precipitation decreased late on December 30th. The greatest ice accumulations were reported from Mitchell to Springfield, especially in western Hutchinson and Bon Homme Counties, where almost a half inch of ice accumulated in places. Tree branches and power lines were brought down by the ice with resulting power outages. Peak snow accumulations of 6 to 10 inches were a little west of this area over Jerauld, Aurora, Douglas, Charles Mix, and eastern Gregory Counties. Travel was slowed or brought to a standstill, and numerous vehicles slid off roads.
