A ridge of high pressure was in place from the Carolinas across to north Georgia early on the 22nd. A very moist airmass was associated with this area of high pressure, and as a shortwave moved across the Southern Appalachians, several showers and thunderstorms developed. A couple of these produced isolated flash flooding.
