Several supercell thunderstorms rolled southeast from northwest South Dakota into central South Dakota bringing large hail, damaging winds, and flash flooding during the late afternoon and evening hours. The large hail and high winds killed a large number of birds, pheasants, grouse, and rabbits. Thousands of acres of grassland and cropland along with countless shelter belts received minor to major damage in Stanley and Hughes County.  The large hail also knocked out many windows and damaged the siding of tens of buildings and homes in both Stanley and Hughes counties. Many roads and cropland were also affected by flash flooding throughout Hughes and Stanley counties. Pierre and Fort Pierre were the cities most affected by the flash flooding. A Federal Disaster Declaration was issued for Hughes and Stanley counties mainly for the flooding.
