 Brief Description: EVENT NARRATIVE: An EF2 tornado with maximum wind speeds of 120 miles an hour occurred around five miles southeast of Pound, Virginia. Tornado damage was observed along the path which measured 1.7 mile in length with a path width of 120 yards. Two trailers along with several outbuildings were destroyed while one trailer was damaged. Numerous trees...some in clusters...were downed by the high wind speeds generated by the tornado. EPISODE NARRATIVE: A highly organized mesoscale convective vorticity maximum with strong low to mid tropospheric flow coupled with moderate instability resulted in the development of discrete supercellular thunderstorms. These storms produced a long-lived tornado across Northeast Tennessee late in the afternoon and another long duration tornado across Southwest Virginia later in the evening.
