|Brief Description: EVENT NARRATIVE: The tornado, originally an EF-0, initially touched down just north of Squire Davis Park near the intersection of Sandy Ridge Road and Johnson Street. From there the tornado tracked northeast and intensified to EF-1 intensity as it approached the Farmers Market and Interstate 40. The tornado overturned several cars and tractor trailers as it crossed Interstate 40. A roof was blown off of an office building just north of the interstate as the tornado continued to intensify. As the tornado moved further northeast into an industrial complex, it further strengthened to EF-2 with winds estimated around 130 mph based on damage to warehouses. Numerous warehouses along Little Santee Road, Capital Drive, and West Market Street sustained significant damage. Numerous vehicles and tractor trailers were also overturned in the industrial complex. At its widest point, the tornado was just over 200 yards wide. The tornado quickly lifted off of the ground after crossing West Market Street near the post office. The tornado was on the ground for about four miles. One fatality occurred along West Market Street next to the Lamination Service Building located at 8717 West Market Street. The fatality occurred as a 51 year old man slept in the rig of his tractor trailer. Three other injuries were reported, two of which occurred in automobiles and another in the I.H. Caffey Warehouse Distribution Center. 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: The tornado initially touched down as an EF1 with winds around 100 mph near Old Plank Road in southwest Guilford County. It was in this area where the Apple Tree Academy sustained significant damage and two vehicles including a small bus were rolled 50 yards across the street. From this point the tornado continued northeast across Highway 311. The next area to experience damage was just north of Highway 311 and south of Old Mill Road along Langdale, Imperial and Impala Drives. Tornado damage in this area continued to indicate EF1 winds with numerous trees down along with a number of home with roof and siding damage. The tornado intensified to an EF2 as it crossed Old Mill Road towards Johnson Street. The EF2 tornado severely damaged numerous homes along Brandon Drive. In on instance, an entire bedroom was blown off a single story home. Three individuals who were taking shelter in a bedroom closet were carried 50 feet and were buried under the debris. One individual experienced several broken bones but overall injuries were not serious. The remainder of the house was shifted off the foundation approximately 8 inches. EF2 tornado damage continued north of Old Mill Road to Skeet Club Road along either side of Johnson Road with winds around 130 mph for most of its duration but briefly reached EF3 intensity with winds of 138 mph near Hampton Park Drive at 1278 Silverstone Court where the upper level of a two story home was blown off. Fifty to sixty homes along Hampton Park Drive, Scarlet Drive, Ruskin Drive and Johnson Road were severely damaged. The tornado crossed Johnson Road as an EF2 crossing Elmwood Avenue, Oakforest Drive and Maplewood Avenue. Nearly every home in this highly urbanized area experienced minor to moderate damage. The upper floor of a two story home on Elmwood Avenue was blown off. The tornado weakened to an EF1 as it crossed Maplewood Avenue and Wellingham Lane, where numerous homes experienced roof and siding damage. The tornado finally lifted off the ground north of Kendale Road. In total 603 single family homes were damaged with 21 homes being completely destoryed. Thirty-one multifamily homes were damaged with 16 reported destroyed. Finally, eleven businesses sustained damage, with 3 businesses completely destroyed. EPISODE NARRATIVE: Convection developed ahead of an amplified upper trough across the Tennessee Valley while a strong southerly mid and upper level jet provided strong shear across the region. Tornadoes formed and track ahead of a developing surface low across Georgia and along a wedge front located across the western Piedmont of NC.|

|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.|

|Brief Description: EVENT NARRATIVE: An EF1 tornado exited Rowan County, crossing the Yadkin River and entered into Davidson County. Numerous hardwood trees were either sheared off or uprooted in a wooded area south of Seven Oaks Drive. A carport was ripped from a brick home on Seven Oaks Drive. Two out buildings were also destroyed. The tornado tracked northeast across an open field before it damaged a vacant steel framed flea market building. The tornado glanced the southeastern corner of the main flea market building, tearing it away from the remainder of the building.
