The Southern Appalachians Derecho of 2016

A long-level, intense complex of severe thunderstorms impacted the region on the afternoon and evening hours of Friday, July 8, 2016, bringing widespread, significant straight-line damaging wind damage to a majority of the counties across the National Weather Service in Morristown's County Warning Area (CWA). This was a semi-rare, particularly intense event that produced widespread, intense wind damage across much of Middle and East Tennessee, likely the worst observed across the region in nearly four years (July 5, 2012). It was also another important (and sobering) reminder that damaging straight-line winds can be just as deadly and produce just as much damage as weak EF-0 to EF-1 tornadoes. This study aims to highlight the meteorological factors in place that made this event so significant as well as highlight the role that the local terrain plays in Southern Appalachians of magnifying the winds associated with downburst.
