Overview

A surface boundary extended from southern Minnesota into northeast Iowa on Wednesday, June 17th. Warm and moist air pooled up to this boundary, leading to shower and thunderstorm development by early evening. The atmosphere was unstable enough and wind shear was favorable for storms to become severe very rapidly, producing large hail and even a couple tornadoes. The confirmed tornadoes were located in Mower County, Minnesota - in and around Austin (damage path) and several miles west of LeRoy, MN.
