Severe storms with large hail formed over southeast Minnesota with a lucky few seeing heavy rain.

A weak cool front sagged to the south across central and southern Minnesota on Thursday, June 17, 2021. Dew point temperatures surged into the low 70s out ahead of the front in southeast Minnesota. In the late afternoon and early evening strong to severe thunderstorms formed out ahead of this cool front and brought some welcome rains, as well as unwelcome hail. A swath of large hailstones from golf-ball to baseball size fell just south of Cannon Falls in Goodhue County, right over the same area that saw tornadoes on September 20, 2018. Cars and some buildings were damaged just south of Cannon Falls.

The heaviest rain fell at Minnesota City in Winona County with 2.78 inches. Much of the state escaped the severe storms... and the badly needed rain.
