What happened

The episode as NWS ABR wrote it up.

A surface low pressure area moving across the region along with a cold front dropping in from the north brought numerous severe thunderstorms to central and northeast South Dakota. Damaging winds were the main occurrence throughout this event with only a few hail reports. Severe winds gusted up to around 100 mph at times as the storms moved quickly east through the evening and early morning hours. As a result, there were many reports of damage to structures and trees across the region.
