A rare and unique anticyclonic landspout tornado touched down in southern Bedford County off a left splitting supercell and an anticyclonic rear flank downdraft coupled with strong southwesterly surface flow. The damage path started off of Charlie Russell Road consisting of uprooted and snapped trees as well as a barn sustaining significant damage from rear flank downdraft winds.  The path continued northeast uprooting and snapping dozens of hardwood and softwood trees. Off of Highway 412, several homes sustained roof damage as well as loss of underpinning off of a couple of mobile homes.  Additional barn damage was observed on Womack Road along with several more trees uprooted and snapped. Significant tree damage occurred off of Narrows Lane including a 4ft wide oak tree snapped at the base.  The tornado then weakened and continued northeast across Highway 82 and Highway 130 blowing down more trees. Entering Shelbyville, the tornado weakened further, but still blew a boat across a parking lot, shifted a few cars, and tossed a dumpster at the Davis Estates Apartments on Anthony Lane, then blew down some playground equipment at Coopers Steel Manufacturing on Hillcrest Drive before lifting. The tornado was widely viewed and documented on video by numerous residents of the area.
NWS Nashville greatly appreciates the opinions and expertise from NWS Norman and NWS Huntsville in determining the characteristics of this very unique event.
