What the National Weather Service wrote

Hail to the size of golf balls fell at the Rapid City National Weather Service office and across much of east Rapid City.

The wider storm

A supercell thunderstorm developed near Piedmont and moved slowly southeastward across the Rapid City area and the eastern foothills of the Black Hills. The storm produced very large hail, which caused significant property damage from Johnson Siding and Hisega to Rapid City. The storm also spawned a very brief tornado over prairie land east of Hermosa. Runoff from the slow moving thunderstorm caused street flooding in Rapid City and Rapid Creek to quickly rise into the greenway through town.

Began near Rapid City (44.0727, -103.2109).
