| 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: 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: Tornado began near Santuc as a large multi-vortex F3 tornado. Spotters engaged the storm almost immediately and followed it as it curved north to northwest through the County. The storm had intermittent ground contact of about 30 to 40 percent but there was not a great deal of separation between areas of damage. The path width gradually diminished to about 50 yards from 0.75 mile initially, and the storm intensity gradually weakened to F2 and then to F1 at Pauline. The tornado crossed into Spartanburg County near Pacolet Mills at 1545EST. A well constructed home near Santuc was destroyed, a stationary vehicle was thrown aout 150 yds, and other homes and structures received severe damage along its path. | |||||||||||

| Brief Description: EVENT NARRATIVE: This strong tornado touched down near the intersection of Locust Trail and Tola Houser Lane. Several homes at the beginning of the track received major damage to the roof and exterior wall. One home was shifted off its foundation by nearly 20 feet, with an upstairs room removed. Two vehicles at this location were rolled several yards. The tornado moved northeast across Northbrook III School Rd. Several homes were damaged or destroyed and numerous trees snapped off or uprooted just north of the Reeps Grove Church Rd intersection. The damage path at this point was nearly 200 yards wide. The tornado continued northeast, crossing Macedonia Church Rd, Peeler Rd and Patriot Way, with additional homes as well as barns and a chicken house damaged or destroyed. Numerous trees were uprooted or snapped off in this area as well. As the tornado continued east northeast, damage became more intermittent in the area around Palm Tree Church Rd, where only the tops of trees were snapped. The tornado entered into Catawba County in the vicinity of Dansbury Lane. Eleven people were injured, two seriously. EPISODE NARRATIVE: Scattered supercell thunderstorms developed over the western Carolinas and northeast Georgia as strong wind shear and moderate instability overspread the region ahead of a strong cold front. A number of tornadoes were spawned by the storms. Two strong tornadoes affected the western piedmont and foothills of North Carolina. | |||||||||||

| Brief Description: The same supercell that produced the tornado in McDowell county spawned a strong tornado in the Vale and Cat Square area. Four homes were destroyed, 50 homes were damaged, a church roof was partially blown off and numerous trees were downed. 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.
