Looks like not just one round of storms, but two instead……….for part of the area……
Intense storms in the Plains last-early AM caused big surface air pressure drop & two meso-lows formed as a result. First one was responsible for blow-up of morning-midday outbreak with widespread damaging straight-line winds along & north of the Ohio River. Other is in Missouri where Tornado Watch has been issued for areas just west of the Tri-State. Those storms have not fired yet.
Much of the area is now rain-cooled, but recovery with some sun will result in the next round to hold together for at least part of the area. Thinking at this moment best potential of the next round producing severe weather is along & south of the Ohio River, but we will monitor. Timing would be this evening. It would appear that areas to the north of the Ohio River would have much lower potential of any additional severe weather.
Potential is there for localized flash flooding as well.
