The combination of summer heating and high low level moisture content provided the necessary conditions to create a highly unstable environment across the Southern Appalachian region. The instability and more than adequate upper level west to northwesterly flow allowed an mesoscale convective system to remain quite strong as it moved east across the area. Downburst winds in some areas were in the 60 to 70 mile an hour range with speeds as high as 80 miles an hour estimated. Trees were downed across a broad area and resulted in the deaths of three people.
