| Brief Description: EVENT NARRATIVE: An EF-2 tornado with maximum wind speed of 110 miles an hour occurred around five miles southwest of Tazewell. The tornado initially touched down along Cole Road and quickly produced 110 mph winds. It lifted the roof off of a home on Cole Road moved east across the road and moved east across the road and destroyed two large wooden barns carrying debris up to a half mile away. Several trees were also snapped off at mid trunk level. The tornado continued in a 2.2 mile path and dissipated near Neely Road. 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. | |||||||||||

| 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.
