Multiple rounds of thunderstorms moved across the region through the course of the day. The first line of storms produced a weak tornado and a microburst, both with estimated winds of 85 mph, near Norris City, Illinois. Another microburst with peak estimated winds of 90 mph carved a 25 mile long, two mile wide damage path across northwest Posey County through southern Gibson County, Indiana. The worst damage was in and around Fort Branch, Indiana, where several homes were damaged and a semi was blown over. This line of storms also produced numerous reports of wind damage as it moved through portions of southern Illinois, southwest Indiana, and northwest Kentucky during the morning hours.

Additional development then occurred over southeast Missouri by mid-afternoon with this cluster spreading eastward through the early evening hours. The second line of storms produced a microburst with estimated winds of 85 mph, which caused extensive tree damage near Breman, Kentucky, in Muhlenberg County. Finally, another line of storms moved in from south-central Missouri around 630 p.m. and progressed rapidly through the area, exiting by around 10 p.m. Damaging winds were the main impact associated with all three rounds of storms, with plenty of great shelf cloud pictures. We had over a dozen observing stations report winds between 45 and 63 mph. Torrential rainfall of 1 to 2+ inches was observed in some areas along with some reports of hail, mostly up to the size of nickels. However, there was a report of ping pong ball sized hail in Van Buren, MO.
