| Brief Description: EVENT NARRATIVE: An EF2 tornado with a maximum wind speed of 135 miles an hour occurred around five miles southeast of Huntsville. The tornado initially touched down just west of the Fairview community with a maximum wind speed of 90 mph (EF-1) and a width of 100 yards. The tornado continued along an east path and increased in size and intensity to an EF-2 with a maximum wind speed at 135 mph and a width of 200 yards. Several large hardwood trees were snapped off near trunk level and a free standing cell phone tower was collapsed and twisted by the tornado winds. Extensive damage occurred in a concentrated path at least 80 yards in length at the 135 mph EF-2 level. The tornado continued east and finally weakened to an EF-1 with a maximum wind speed of 100 mph as it dissipated at the foothill of Gray Mountain. At least seven homes suffered minor to moderate wind damage along the 4.5 mile path of 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. | |||||||||||
