Overview

On July 8, 2021, a powerful supercell thunderstorm tracked from extreme southeastern Montana to just east of the Black Hills and into north-central Nebraska. This storm made a direct hit on the NWS Rapid City radar just north of New Underwood, South Dakota. Hail up to tennis ball size and wind gusts up to 70 mph produced damaging wind-driven hail that affected much of the storm's path. Satellite images revealed vegetation damage several days after the hailstorm.
