A complex of thunderstorms that developed early Tuesday morning across South Dakota, moved quickly eastward across southern Minnesota, with numerous reports of large hail, severe wind gusts, and torrential rainfall.
As the thunderstorms moved across the southern metro, the line of storms intensified and caused widespread damage from Lakeville, eastward to Hastings.  Hundreds of trees and power lines were blown down, aircraft were flipped over at the Lakeville airport, and damage occurred to an apartment complex in Hastings.
In addition to the damage across the southern metro, farmers across southern Minnesota, from Redwood Falls to New Prague, were hit by large hail and high winds. The combination of the hail and high winds caused a large swath of crop damage, up to 15 miles wide in some areas to corn and soy beans. Some farmers had a total loss as the hail shredded corn and soy bean fields.
Wind storms and flooding during the period June 14-21 led to Dakota, Goodhue, Kandiyohi, Meeker, Rice and Sibley counties being among those Minnesota counties designated disaster areas by presidential declaration on July 6, 2012.
