What happened

The episode as NWS ABR wrote it up.

A cold front draped from the upper James River Valley down into south central South Dakota triggered a severe thunderstorm during the early afternoon across north central South Dakota, and then a more significant and widespread bowing line of thunderstorms from central into northeastern South Dakota during the evening. The environment featured hot temperatures in the 80s and 90s and muggy conditions. The main thunderstorm complex produced straight-line winds of 60 to 85 mph, including a measured gust of 85 mph three miles south of Bunker, 82 mph ten miles southwest of the Chantler Creek Rec area, 80 mph eighteen miles south of Seneca, and 79 mph at the Pierre Regional Airport. There were several reports of property damage including numerous uprooted or damaged trees.
