A complex of thunderstorms developed across south central South Dakota during the pre-dawn hours. These storms continued to move eastward into southwest Minnesota during the morning, and generated an outflow boundary that created thunderstorms across south central and portions of southwest Minnesota prior to noon. Marginal instability and wind shear allowed for a few large hail reports, along with a few wind gusts of 50 to 60 mph. One large hail signature (Three-body Scatter) was noted with strongest early afternoon storm near Mankato, which produced copious amounts of small hail. The combination of the amount of hail, and the wind, crop damage was reported in Nicollet County, east of Nicollet, Minnesota. Eyewitnesses said that one to two foot drifts were noted with the hail swath, which sheared off young corn stocks.
