Some areas just south of Castlewood had hail piled up to six inches deep. Leaves were stripped from several trees. Wind gusts to 60 mph accompanied the hail. Another thunderstorm produced strong winds and damaging hail in Grant and Roberts Counties. North of Milbank along both sides of Highway 15, crops incurred considerable damage. An area 17 miles northeast of Sisseton into Browns Valley, to Mud Lake saw crop damage from golf ball size hail.

June 14, 2009:

An upper level disturbance combined with a warm front and very unstable air brought severe thunderstorms to parts of central and north central South Dakota. Hail up to the size of golf balls, flash flooding, along with several tornadoes occurred with these storms. Heavy rain caused flash flooding on the Moreau River with the bridge on Route 14 being overtopped. The bridge had to be closed west of Green Grass. A basement was also flooded three miles east of Green Grass along with several roads in the area in Dewey Country. A tornado touched down west of Hayes in Stanley County and traveled almost a mile before lifting. No damage occurred. A second tornado touched down east of Hayes with no damage occurring.
