The thunderstorm that would eventually produce the Sanford-Raleigh Tornado and the Roanoke Rapids Tornado initially developed to the southeast of Lancaster, South Carolina just after 115 PM. The thunderstorm intensified as it moved into North Carolina and approached Wadesboro. The storm then became a supercell as it developed a persistent rotating updraft as it moved into Moore County just after 230 PM. At 253 PM the storm produced a tornado in northeastern Moore County. The tornado strengthened as it moved across southeastern Sanford. The circulation in the storm remained intense as the storm moved across Chatham County into Wake County (reflectivity image & storm relative velocity image). The rotation within the storm weakened as it moved through Holly Springs with EF-0 to EF-1 damage observed from Holly Springs to southern Raleigh (reflectivity image & storm relative velocity image). The storm weakened a bit as it moved through downtown Raleigh before intensifying as it moved across northeastern parts of the city. A persistent path of EF-2 damage was noted in Raleigh from Stony Brook Drive (reflectivity image & storm relative velocity image) to Buffalo Road and Forestville Drive. The tornado began to weaken as it moved across far northeastern Wake County with damage becoming sporadic and isolated as it moved into Franklin County.
