Enhanced southerly flow advected warm, moist air into the region ahead of a diving shortwave trough and attendant cold front. This resulted in sufficient moisture, strong shear and marginal instability to produce a line of showers and strong thunderstorms. These storms produced scattered wind damage, localized flash flooding and a brief tornado as they moved through central North Carolina.
