"She had a Southern Drawl that was just dripping with Dixie."
Drawls run the gamut of the light drawls from Southern Maryland and the Eastern Shore, getting progressively heavier as one heads South through Virginia and the Carolinas into Georgia and Florida and West through West Virginia, Kentucky, and Tennessee, down to the deep drawls of the Deep South in Mississippi, Alabama, Arkansas, and Louisiana, and over to Texas.
Wikipedia also has an entry for drawl, which points to articles on Southern American English and Australian English.
