A quasi-stationary frontal boundary was the main focusing mechanism for a round of significant severe weather over the forecast area. A strong shortwave moved along the boundary triggering widespread showers and thunderstorms. Numerous reports of large hail, damaging winds and 22 tornadoes occurred with this system. A tornado touched down about half a mile west of the intersection of Lone Grove School Road and Hesemann Road. In this location it broke off and uprooted numerous trees. As it travelled to the east it blew over a hay wagon and overturned a couple of tanks and farm equipment. A nearby home sustained minor roof damage and a shed was completely flattened. It blew over more trees before crossing Lone Grove School Road. At this location it blew part of the roof off of a large barn. It travelled a little further to the east blowing down a few more trees near Grannemann Road before lifting and dissipating. The max width of the tornado was 175 yards and was on the ground for three quarters of a mile. It was rated as EF1.
