I agree. At this point, the Mid Atlantic and Carolinas is setting up for a significant tornado event, one perhaps not seen since 2/24/16. Dixie on Sunday conditionally remains potential for significant damaging winds and several tornadoes.
Prefrontal convection is unusual given that robust instability isn't in place. You need enough instability with no hostile factors to get WAA convection firing and then you mature and go from there for Sunday. I personally believe more in a QLCS here. Even if the mode remains QLCS here on Monday, that is a profile still capable of intense tornadoes from the QLCS alone. This may be a very notable event.
