A very large area of severe weather continues to unfold over portions of the Mississippi and Ohio Valleys tonight, setting the state for not only a violent night, but a continued threat for tomorrow. Damaging wind gusts, large hail, and tornadoes are possible here; nighttime tornadoes can be especially lethal since many are asleep and aren’t aware Tornado Warnings are issued.
The National Weather Service has issued Tornado Watches across a large area tonight. Tornado Warnings are also being issued within the Watch area, which expands across southern Illinois, central and southern Indiana, southern Ohio, western and central Kentucky and Tennessee, southeastern Missouri, and northwestern Arkansas. In addition to Tornado Warnings, Severe Thunderstorm Warnings have also been issued at times.
Many weather features are responsible for this latest severe weather outbreak. A subtle shortwave trough over the Great Lakes is moving south and east. The southern extension of this feature is in the mid-Mississippi Valley while a cold front is located from central Indiana southwestward into south-central Illinois. It is along this front that a band of strong to severe thunderstorms are firing up.

The threat of severe thunderstorms and isolated tornadoes will linger into the overnight period tonight. The threat of severe weather will then shift to the East Coast tomorrow. For now, the National Weather Service’s Storm Prediction Center believes the greatest threat of severe weather on Thursday will extend from southeastern New England through the metro New York City area down into Philadelphia, Baltimore, Washington, DC and eastern Virginia and North Carolina.
