August 22, 1985:

Intense thunderstorms moved from near Shadehill Reservoir in northwest South Dakota late in the evening of the 21st, to northern Brown County after sunrise on the 22nd. These thunderstorms produced strong winds, large hail, heavy rainfall and lightning. Considerable crop and property damage was caused mainly by the strong winds and hail. Winds gusts ranged from 55 mph at Mobridge to 60 mph in and around Akaska. Winds of 70 mph were reported at Onaka and Faulkton. The strongest wind gust was reported in Hoven with a peak gust of 72 mph. Widespread damage was reported throughout the area. Many mobile homes, storage sheds, silos, and roofs were damaged or destroyed. Nine miles south and four miles west of Keldron, over two inches in diameter hail fell for 40 minutes, breaking windows and piling in ditches to a depth of four feet. These intense thunderstorms also produced brief heavy rainfall ranging from three quarters of an inch to over four inches.
