The tornado first touched down along Arlington Road just south of Potato Ridge Road where there was light damage to hardwood trees consistent with EF0 strength winds. The tornado then progressed north-northeast and crossed Sweet Potato Ridge Road and then Arlington Road, where it severely damaged a barn and woodshed.  Just north of this location, a farm house on Baltimore Phillipsburg Pike had extensive damage with the entire roof lifted off from the upper level of the house. With consideration of the age of the home and roofing structure, the damage was consistent with high end EF1 damage. At this same property, a garage was shifted off its foundation with all walls collapsed and a nearby large barn lost about 20 percent of the roof.
Additional minor roof damage occurred at a property on the north side of the Baltimore Phillipsburg Pike property, with most of the damage coming from the roof debris from the property on the south side of Baltimore Phillipsburg Pike.
The roof and yard debris from the Baltimore Phillipsburg Pike location was lofted as far as 300 to 400 yards from the home site, northward toward Blank Road. An additional farm site farther north along Arlington Road suffered a destroyed garage with debris from the structure spreading nearly 100 yards. Additional damage included chimney damage, snapped and uprooted trees, siding and significant barn damage. This damage was in the high end EF0 to low end EF1 scale.
The northernmost location of tornadic damage occurred along State Route 49, just north of Montgomery County Line Road in Miami County, where some large trees were downed. This was the northernmost indication of ground-based damage. There was additional debris in fields just north along Castine-Gordon Road, but this was the last known location of damage or debris.

Damage was first observed along Grubbs-Rex Road. A large garage had one of its doors partially pushed inward. The most significant damage occurred at a property located south of Dull Road. A horse stable at the southern end of the property was almost completely destroyed. The southernmost addition to this stable suffered from complete collapse of external walls with some of the wooden anchor posts completely ripped from the ground. Minor damage to walls, windows and roof ornamentation was also noticed on two other outbuildings at this location. A brick house was generally undamaged, aside from some isolated removal of shingles. Throughout this area, tree damage was significant. Large limbs were spread almost everywhere with several trees downed and others snapped off above ground level. Debris from the stable was found deposited in trees in several other places on the property.
Debris from the Dull Road location, including large pieces of sheet metal, was spread for long distances to the north of the property. A significant amount of this debris was deposited between the damage area and Dull Road. Very minor roof damage was also observed on a barn located just north of Dull Road.
Numerous pieces of debris were found between Dull Road and east South Street (State Route 49). A few pieces were even found just north of east South Street. A lack of trees along this segment of the path made it difficult to determine the exact end point of the tornado. It is estimated that the tornado lifted in the vicinity of east South Street.

The first evidence of damage occurred north of Stocker Road just east of the intersection with Schnorf-Jones Road. A few trees were downed in this location with some light debris noted along the tree line about 350 feet north of Stocker Road.
Additional damage was noted at a residence on the northeast corner of the intersection of Oakes Road and Schnorf-Jones Road. A stone chimney on the house was heavily damaged. A few panels of metal roofing on the house were completely removed. A metal barn roof at this location was also partially peeled up to the west.
Light debris from the above location was spread about a quarter mile to the north with some evidence of very minor damage at an adjacent property just south of a line of trees. Beyond this line of trees, which had some depositing of light debris, there was no further damage observed.

Damage was first observed northwest of Wheatville along State Route 122 between Quaker Trace Road and Yost Road. This is believed to be where the tornado first touched down. A section of wood and metal roofing material measuring approximately 55 feet by 15 feet was lifted from the northeast side of a barn and strewn for approximately 100 feet to the northeast, and a lesser distance to the northwest. A utility pole was also snapped at this location. Eyewitness accounts from the residents indicated the damage resulted from a visible circulation that passed through the property. The residents also pointed out a section of metal roofing material from this location that was carried approximately 0.35 miles north-northeast and deposited in an area of trees. The damage here was assessed to be in the mid range EF1 category.
A second debris field was found along Halderman Road just west of the intersection with Quaker Trace Road. A barn measuring approximately 65 feet by 45 feet was completely destroyed just south of the road. Wood and metal roofing material from this barn was strewn over approximately one-half mile in a very confined path. The debris was oriented to the north-northeast for much of the total distance, although an initial jog to the west was visible in the immediate vicinity of the barn. The final pieces of debris were visible in a field about one-quarter mile north of Halderman Road. No further damage was observed or reported north of this location so this area is believed to be where the tornado lifted. A close inspection of the barn was not possible due to its location on private property, but the visible debris and available aerial imagery indicated it was not of new construction. It is also unknown if any parts of the structure were open to the wind prior to being destroyed. For these reasons the damage at this location was also assessed to be in the mid range EF1 category.

The first evidence of damage occurred at a property on Hall Road. A few shingles were damaged on the house and one tree had a large limb broken off. A more concentrated area of damage occurred along and east of Stauffer Road, just north of the intersection with Coppock Road. Minor tree damage was observed at several properties on Stauffer Road, with a few healthy trees downed. A pine tree near the north end of the damage path was blown toward the southeast. One home had its sheet metal roof almost completely peeled off and deposited to the west of the home. Minor shingle damage occurred to a nearby garage. There was also significant scattering of minor debris in this location, including small limbs and a play structure. A shed located behind one of the residences was also destroyed with its debris scattered northwest into an adjacent field.
