There were two tornadoes and many reports of very large hail.
Storms brought strong winds, heavy rain, hail and tornadoes to south central Minnesota, damaging buildings and crops in Blue Earth, Nicollet and Sibley Counties.
The July 9 tornadoes, thunderstorms and hail hit south central Minnesota hard, with softball-sized hail reported in the Sibley County towns of Gibbon and Winthrop. The National Weather Service confirmed two tornadoes, one which did severe damage to a Courtland farm site.
That large hail and major thunderstorm surfaced quickly near the McLeod-Sibley county line, then continued south toward the Iowa border. Crops in Blue Earth, Nicollet and Sibley counties sustained severe damage, with the Blue Earth County Sheriff���s Office reporting over 600 acres hit there.
Still, the worst hail damage seemed to focus in rural Nicollet County, where corn fields were stripped and soybeans badly damaged. The University of Minnesota Extension Service, which conducted a Thursday clinic for regional farmers at the United Farmers Cooperative headquarters in Winthrop, said corn has the ability to come back somewhat from the damage, but the soybean crop for some farmers might be gone.
