Front has drifted south of Ohio and Indiana now and is at weaker overnight intensity in KY-TN-nAL, will probably keep drifting further south and could redevelop to severe levels by noon in Carolinas, southern parts of AL and GA, west to s.e. LA. across northern Gulf into south Texas.
Very likely to redevelop with day due to day time heating.
The greater the temperature contrasts, the worse the severe weather. That is why GENERALLY, tornado outbreaks weaken some overnight.
