That system around the 7th - 8th could trend south and east, especially since there is a strong high moving south and east. I'd use a blend between the GFS, FV3 and Euro, so there could be something for the majority of the southeast region for the 7th - 8th window.
I hate to say this, but again, it could turn out to be cold playing "catch up." There hasn't been enough consistency yet for my liking to really put thoughts towards a solution that has a good chance at verifying.
Something did come to mind though, it may turn out to be an over running event for the western portion of the southeastern US, and then an actual low develops on the tail end of the front from the cutter after the 7th (or 8th) that brings the eastern parts of the southeastern region at play.
