EF4 dispute
On August 26, 2016, the National Weather Service in Northern Indiana rated the tornado a preliminary very high-end EF3 with winds of 160-165 mph due to damage to several structures and some ground scouring northwest of Woodburn. However, within a few hours, surveyors had noted several instances of likely EF4 damage, and noted in the final survey on August 29 that "the tornado likely was capable of producing EF4 damage at one point or another during it's intensification.", this sparked a large dispute over whether or not a EF4 rating should be required for the tornado, with EF4 damage likely occurring to a barn northwest of Woodburn, and a farm vehicle was severely twisted and it's engine has never been found.
