Golf ball size hail fell in Hayti, creating three foot drifts of hail.

Hail, up to golf ball size, cut a swath 1.5 miles wide and 50 miles in length from the Missouri River east to the Hyde County line. Thunderstorm winds destroyed a granary roof and downed numerous trees. Damage from large hail was considerable to crops with complete fields being wiped out. The County Agent placed crop damage estimates at 1.8 million dollars in Sully County. Hail also produced window damage to cars and homes.

June 11, 2008:

A strong inflow of moist and unstable air into and over a surface warm front resulted in training thunderstorms and very heavy rain across parts of northeast South Dakota. Rainfall amounts of 2 to 6 inches occurred across much of the area resulting in widespread flash flooding. Many roads, bridges, and cropland were damaged by the flooding. In Milbank, many basements were flooded and/or received sewer backup.
