|Brief Description: EVENT NARRATIVE: A low end EF-2 tornado touched down on Osee Road and was intermittently on the ground approximately 5 miles moving east-southeast, finally lifting between Old Barrett Road and Glade Valley Road. A single wide mobile home was destroyed on Osee Road, causing four injuries. Along the track, cement silos were collapsed, 5 other homes were damaged, and several other structures were heavily damaged. Two people received minor injuries when struck by debris after winds blew out windows in their home. Monetary damages are estimates. EPISODE NARRATIVE: A thunderstorm complex over Kentucky and Tennessee moved east into the area during the evening of May 8th. The storm environment was such that storms would have rotation due to strong wind shear, and a low level boundary in place. Supercells developed over southeast Kentucky and moved southeast into far southwest Virginia and into northwest North Carolina during the late evening of May 8th. One storm produced an EF-2 tornado in Northern Alleghany County, with another brief EF-1 tornado touching down just south of the EF-2 track.|

|Brief Description: This tornado touched down in the Houstonville Rd area and tracked almost due north. Extensive damage was done to a dairy farm in the Houstonville community, with damage to several other agricultural buildings in the area. In the Misty Rd, Anthony Rd area, the roof was torn off a mobile home as well as another home. The tornado continued to track north, crossing into Yadkin County around Tobacco Rd. At least 13 structures were damaged or destroyed in the county. In addition to the structural damage, damage to tobacco and corn crops was extensive. In addition, numerous trees were blown down along highway 21 and Hunting Creek Rd west of the tornado track. It is unclear whether this was a secondary spin-up or straight-line wind.|

|Brief Description: This tornado touched down near highway 16 just north of the Catawba County line. Two brick homes and a business received severe roof damage in this area, while a mobile home was completely destroyed. The tornado tracked northeast, damaging the roofs of several homes at a mobile home park along Friendship Church Rd before lifting near the intersection of Millersville Rd and Dairy Rd. Numerous trees were also blown down along the tornado path.|

|Brief Description: A violent, F4 tornado touched down near Dudley Shoals then moved east-southeast cutting a winding path through valleys, to the Alexander county border. The damage path was 100 yards wide on average, but reached a width of 3/4 of a mile at times. One well-constructed home was totally destroyed, other homes were damaged, and many mobile homes 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: The tornado touched down initially in an industrial park near Penny Rd, where two large buildings sustained significant roof damage. Part of the exterior wall of one of the buildings collapsed. The tornado moved northeast, causing damage to shingles and siding at several homes on St Vincent Dr. Two outbuildings were thrown 30 to 40 feet and numerous trees were snapped off or uprooted in this area as well. The tornado continued to cause severe damage to trees and generally minor structural damage to homes and a church as it moved northeast toward Catawba St. The damage path continued in a east northeast direction from there, roughly paralleling highway 70. Major roof damage occurred to a food processing plant on highway 70 and several outbuildings were destroyed. Numerous headstones were blown down in a cemetery adjacent to the plant. Numerous trailers were then overturned and part of a building destroyed at a truck depot near Liberty Hill Church Rd. The tornado continued east northeast for about another half mile before lifting. 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: EVENT NARRATIVE: An EF-2 tornado tracked northeast out of Davie County and crossed the Yadkin River into Forsyth County. After crossing the Yadkin River, the tornado touched down near the Old Clemmons Water Treatment Plant along Idols Dam Road. The tornado tracked northeast through a heavily wooded area for just over one quarter of a mile and then lifted off the ground. The parent supercell thunderstorm went on to produce another tornado approximately one mile northeast of the first tornado's ending point. This second tornado went on to produce significant damage to the Clemmons community in Forsyth County. EPISODE NARRATIVE: A strong upper level low moving east-northeast across Kentucky and Tennessee, triggered several instances of severe damaging winds and two tornadoes across the Triad region in the northwest piedmont of North Carolina.|

|Brief Description: EVENT NARRATIVE: This tornado originated from the same parent supercell that produced the tornado in Davie County which lifted in Forsyth County just across the Yadkin River. This second tornado touched down just southwest of Hampton Road. Three metal barns sustained major damage around the 4800 block of Hampton Road with minor damage to two homes. The tornado continued northeast through wooded farmland before hitting the Bridgepoint Subdivision where the tornado strengthened to EF-3 intensity. Three homes were destroyed and approximately thirty homes sustained moderate damage. There were only two minor injuries in the subdivision. The tornado continued to track to the northeast across Frye Bridge Road and through a heavily wooded area. It then dissipated near the intersection of Cooper Road and Fraternity Church Road. A few homes suffered damage, primarily due to fallen trees. Hardwood tree damage in the area was consistent with EF-2 intensity as tree trunks were snapped in a 200 to 300 yard path. The overall path length of the tornado was around 3 miles with a maximum width of 300 yards. EPISODE NARRATIVE: A strong upper level low moving east-northeast across Kentucky and Tennessee, triggered several instances of severe damaging winds and two tornadoes across the Triad region in the northwest piedmont of North Carolina.|
