Spotter reports as well as video footage confirm a tornado touched down near the Benton/White county line and tracked slowly east into White County. The tornado remained over open fields in Benton County and caused damage at a property on the eastern side of the White county line along North County Road 1200 East. A trailer was shoved 15 to 20 feet, along with a fishing boat being flipped roughly 30 feet from its starting location. A wooden outbuilding was destroyed along with a steel patio chair being thrown about a third of a mile. The tornado made a turn to the left near the end of its life, missing a wind turbine and eventually roping out. The tornado was on the ground for roughly 5 minutes with a maximum width of 50 yards and estimated wind speeds of around 75 mph. The tornado was on the ground for roughly three quarters of a mile from start to finish, with a tenth of a mile taking place in Benton county.
Diffuse warm front was lifting slowly north ahead of a MCV moving out of Illinois. This increased effective shear into the range of 50 to 60 knots with a strengthening low level jet aiding in development and intensification of some of the storms.
