Overview

Severe thunderstorms brought large hail, strong winds, and a tornado to western South Dakota on June 19, 2015. Parts of the area were damaged by wind-driven hail, which killed livestock, especially around the Nisland area. Hail around the size of softballs and winds around 100 mph were reported. That storm later produced a relatively long track tornado in southern Meade County, and caused straight-line wind damage to the east-southeast—continuing across central South Dakota.
