Training multi-cell thunderstorms, some of which became supercells, tracked east across the Upstate during the afternoon and evening. A couple of the storms were particularly intense, producing long swaths of golf ball size hail and widespread wind damage. Trees were downed in Calhoun Falls. Golf ball size hail covered the ground for some time in northern Union county. Trees and power lines were blown down in the Travelers Rest area - some falling on houses and a sport utility vehicle. On the eastern shore of Lake Hartwell in Anderson county, 44 trees were uprooted or snapped off and several docks were blown onto the shore. Scattered trees were downed from Taylors to near the GSP Airport. Two people were slightly injured and equipment was damaged when a tent blew down at an outdoor church function in Taylors. Trees and power lines were downed from Reidville to Pacolet, across northern Union county and much of Chester county. Extensive damage to homes and businesses occurred due to falling trees and power poles near Roebuck, Whitestone, and Pacolet. More than 12,000 people were left without power in these areas. Northwest of Union a roof was blown off a trailer, 25 trees were downed - some on cars, and a billboard was blown down.  A tornado was embedded in a large downburst in Adamsburg which damaged a camper, blew a large pontoon boat 75 yards, and produced extensive damage to trees and power lines. The downburst covered several square miles. Cars were damaged by falling trees in Baton Rouge and a roof was blown off a barn in Chester.
