 Brief Description: A tornado developed from a fast moving severe thunderstorm that raced north out of eastern Georgia. The F2 tornado destroyed several houses and mobile homes and severely damaged many other homes and businesses. Damage was sustained to the south of the track of the tornado due to strong inflow into the storm. Damage from severe thunderstorm winds in the rear flank downdraft occurred north into Easley. A powerful winter storm brought flooding rain, high winds, and a tornado to the Upstate from the evening of the 7th into the early morning of the 8th. Rainfall between 4 and 7 inches during a 2-day period across the mountains and foothills resulted in significant flooding. Many roads and bridges were covered or washed out. A wash out in Pickens county resulted in one fatality. Thunderstorms raced north through the area adding to the deluge as well as creating or enhancing strong to damaging winds. An F2 tornado touched down near Easley. Meso-scale high winds behind the complex of thunderstorms moved across the northern half of Greenville county and blew down trees and power lines. Severe thunderstorm winds combined with strong gradient winds to down trees and power lines in York county as well.

 Brief Description: Another supercell which tracked across the mountains spawned a tornado that travelled through a portion of Glenwood. Several homes and mobiles sustained damage or were destroyed. Supercell thunderstorms developed in a highly sheared atmosphere in eastern Tennessee then moved east across the mountains, foothills and western piedmont of North Carolina. These long-lived, cyclic supercells produced a considerable amount of large hail and some damaging winds in the mountains. The first tornado of the day in western North Carolina occurred in Madison county. Numerous reports of hail as large as golf balls were reported from the mountains. In Madison and Yancey counties, hail covered roads. More supercell thunderstorms developed behind the previous ones and followed similar tracks. In northern Buncombe county, the town of Barnardsville had three separate severe storms cross overhead and drop hail on the ground to a depth of 3 inches. Yancey county also had 3 separate storms move across the county that accumulated hail to 6 inches in depth. The hail was still on the ground the next morning. As the supercells moved into the foothills, they began to curve a little to the right, indicative of strong mesocyclonic circulations present. One supercell produced several tornadoes from Alexander county to Davie county. Another storm produced a tornado that tracked from western Caldwell county into south-central Alexander county. A third supercell that emerged out of the mountains in McDowell county produced several tornadoes from the southern part of that county to northern Mecklenburg county. Damage was fairly significant across western North Carolina with numerous homes either damaged or destroyed. Fortunately, no one was killed. However, 2 people were injured as a result of the violent F4 tornado in eastern Caldwell county. One person received minor injuries from a lightning strike in Yancey county later in the evening. The storms continued to reform in eastern Tennessee until very late in the evening and still produced large hail as they crossed the border into the mountain counties of North Carolina, before weakening shortly after midnight..

 Brief Description: EVENT NARRATIVE: A tornado damage path extended from northwest Anderson County, into extreme southern Pickens County, affecting the research area on the south side of the Clemson University campus. Damage was limited to downed trees and power lines. Numerous large trees were snapped off on a ridge very close to the Pickens, Anderson County line, where wind speeds were estimated at close to 120 mph, earning the tornado an EF2 rating. EPISODE NARRATIVE: The remnants of Tropical Storm Fay stalled just west of the Appalachians and slowly dissipated. A line of mini-supercells developed southeast of the low, resulting in several tornadoes over the Upstate and Northwest Piedmont of South Carolina during the afternoon hours of the 26th. A small amount of flash flooding also occurred, though the flooding was much worse in North Carolina.
