The worst of it will be centered around the Mississippi River and Ohio River region, including parts of Missouri, Illinois, Indiana, Kentucky, Tennessee, Mississippi and Arkansas. The brown “enhanced” risk zone is where tornadoes are most likely. Not only could this be a multi-tornado event, but the Storm Prediction Center also says there is a risk for strong tornadoes, meaning EF-2 or stronger.
Complicating matters is the fact that this severe weather outbreak will happen after dark. As is often the case, nighttime tornadoes are especially dangerous as people may not receive crucial information while they’re asleep.
Also, tornadoes are difficult to spot during the night.
