Isolated severe storms developed again during the afternoon in western and central Minnesota, as a leftover boundaries from earlier rains interacted with daytime heating and abundant moisture. One family of regenerating thunderstorms lasted for several hours, producing a tornado near Amelia Lake in Pope County, along with isolated wind damage and hail reports very near areas that were affected one day earlier. These storms can be seen in the upper-left and upper-middle portions of the accompanying radar loop.
Additional storms moved out of South Dakota and Iowa overnight, and produced a swath of wind damage across parts of far southern Minnesota (not shown on radar). In Ellendale (Steele County, mid-way between Owatonna and Albert Lea), the winds knocked out power, blew a railroad crossing guard over, and produced extensive tree damage. Reports of hail up to 1" in diameter were common, and some areas near Mankato received over two inches of rain.
