A warm front passed through central and northern Virginia during the afternoon and evening hours of the 13th. A potent upper-level trough approached the area during the same time causing strong winds aloft. Thunderstorms that developed behind the front were able to produce damaging wind gusts due to the strong winds aloft. Winds rapidly changed in both direction and speed with height causing some of the stronger thunderstorms to produce tornadoes near the warm front.
