The first evidence of tornadic damage occurred on Union Hill Road, about six tenths of a mile north of Appalachian Highway, where a few hardwood trees were snapped and multiple limbs were broken off of trees. The tornado then moved through a heavily forested area towards the intersection of Lansing Road and Chenoweth Fork Road where more tree damage was noted. Tree damage continued in a concentrated path to the east-northeast along Chenoweth Fork Road before crossing Appalachian Highway and causing a fair amount of tree damage at a rest station on Meads Road. The damage noted in the first third of the tornado's path consisted of broken branches, snapped trunks, and uprooted mature trees. This was consistent with EF-0 and EF-1 damage.

The tornado continued east through a forest with a large hillside that was not accessible by ground survey. This coincided with the first evidence of a Tornadic Debris Signature on the Wilmington, Ohio radar. When the tornado came down the ridgeline just west of Elm Grove, the most significant damage indicators were noted. An entire section of hardwood forest, about 200-250 yards wide, was blown down. Drone photography and the ground survey confirmed all hardwood trees in this location were snapped, with none left standing. The estimate for this type of tree damage was around 115 mph, consistent with low end EF-2 damage.

Some higher-end EF-1 damage was observed as the tornado moved northeast off the hillside into Elm Grove, where the complete collapse of out buildings and barns occurred. Additionally, a significant portion of a roof off was lifted off of a house and large power transmission lines were snapped. After Elm Grove, the tornado turned southeast and caused additional damage near the intersection of State Route 772 and Appalachian Highway. The final evidence of tree damage was located on Sun Fish Creek Road, about a half mile south of Tennyson Road.
