The path drawn at its surveyed width of 800 yards (0.45 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF2 means. On the Enhanced Fujita scale, EF2 is considerable damage: roofs torn off well-built houses, mobile homes destroyed, large trees snapped or uprooted, consistent with estimated gusts of 111–135 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

This tornado originiated in Fairfield County, but got stronger in western Perry County. The damage path widened as it crossed several north to south oriented roads. A convergent damage pattern was evident. Large trees were snapped along Avalon Road. A greater swath of tree and structural damage was along Otterbein Road. The damage path widened to as much as 800 yards, though the southern portion of the path was dominant. The tornado unleashed it worst winds as it continued east to encounter Palomino Road and County Township Road 138. At this stage, there was aproximately a 1 mile long and 100 yard wide path of EF2 strength winds, estimated at 110 to 120 mph. A manufactured home on Palomino Road was missing 95 percent of it roof covering and 40 to 50 percent of the roof supports and interior ceilings were missing. The woman inside was injured when a hallway door struck her in the back. There were at least 2 eyewitnesses to the actual tornado. Almost a mile east on County Township Road 138 a cluster of houses was heavily damaged. The worst damage was a newer 2 story single family home, but seemed to be of the manufactured home quality. Its roof and garage were completely blown off and thrown away. The tornado began to weaken as it headed across County Road 25. The tornado further weakened during its final 1.5 miles, ending near the intersection of County Roads 122, 123, and 134. About 8 homes were destroyed in this tornado.

The wider storm

A cold front, in tandem with strong mid and upper level forcing, produced a severe weather outbreak in southeast Ohio into extreme western West Virginia during the late afternoon and evening of Thursday the 16th. The setup featured a 45 knot mid level flow and a 95 knot upper level jet. Matter of fact, a larger area of showers, associated with a warm front, had moved across southeast Ohio and West Virginia during the morning and midday hours. This kept the surface based instability at a minimum. However, new cells formed further west during the mid afternoon over western Ohio. It was this new cluster of convection that would intensify due to the strong mid and upper level dynamics. Several of the new cells formed and intensified on the southern or southwestern flank of the overall larger area of showers and thunderstorms. This area of convection stretched further to the northeast into eastern Ohio and western Pennsylvania. This allowed an unimpeded low level moisture inflow into the new development. Surface dew points ahead of the cold front reached into the mid 60s.

Most of the severe thunderstorms exhibited strong rotation, resulting in the spawning of 5 tornadoes. Four of these 5 tornadoes were in Ohio. One of the 4 Ohio tornadoes crossed from Fairfield County into western Perry County. Another 1 of the 4 crossed from Perry into northwestern Morgan County. One tornado patch was solely in western Athens County. The damage continued another 10 miles in Athens County from a strong rear flank downdraft. Finally, the last of the 4 tornadoes in Ohio crossed the Ohio River from northeastern Meigs County into southern Wood County in West Virginia. From storm surveys, this was the strongest tornado. The last tornado path in this outbreak was solely in western West Virginia. Luckily, there were no fatalities in southeastern Ohio. However, there was one death on the West Virginia side of the Ohio River.

Began near Carthon (39.7594, -82.4025).
