A small, brief tornado touched down in extreme southern Madison County just west of the town of Ingalls at approximately 12:30 AM EST. The tornado began near county road 1050S, just west of county road 750W, pushing the roof off of a house. From there the tornado continued north, damaging a large barn up the hill north of the flooding Lick Creek. The tornado also destroyed a pole barn, damaged a home, and a 30 foot long trailer along county road 1000S. Further damage to trees occurred across the road from the pole barn before the tornado lifted. Based on the damage to the homes and barns, the tornado produced EF1 intensity damage with maximum winds estimated at just over 100 mph. The tornadoes path was just over a half mile long and around 200 feet wide.
In addition to the tornado damage, downburst straightline wind damage was also observed just south of the tornado touchdown near Woods Drive at State Road 67.
