See the devastating scope of damage across Little Rock, Wynne from deadly Arkansas twisters
A severe weather outbreak rocked America’s heartland Friday with violent, long-track tornadoes. A Tornado Emergency was issued for Little Rock, Arkansas moments before a powerful tornado began tearing through the city’s suburbs.
There have been 10 tornadoes rated at an EF-3 so far, including deadly tornadoes that hit Little Rock, Arkansas, Wynne County, Arkansas, Jasper and Crawford counties in Illinois, Sullivan County in Indiana and the Covington and Hornsby/Mount Pleasant areas in Tennessee. Some of those tornadoes may still be upgraded to higher ratings as more data comes in.
HOW METEOROLOGISTS DETERMINE IF A TORNADO IS TO BLAME FOR STORM DAMAGE
NWS storm survey teams found 27 tornadoes reaching EF-2 status, 39 EF-1s and 20 EF-0s. There are six confirmed tornadoes that have yet to be classified.
Same area hit by Friday tornado outbreak under threat of strong tornadoes again

A large area of severe thunderstorms is expected to develop from Tuesday afternoon through the overnight hours in a swath extending from southeastern Minnesota, southern Wisconsin, Iowa, Illinois and western Indiana southward to portions of Missouri, Arkansas, eastern Oklahoma and eastern Texas.

These storms will pose threats of destructive wind gusts, large hail and tornadoes, some of which could be long-track, EF-2 or stronger tornadoes.
NOAA's Storm Prediction Center has rated two areas in their level 4 of 5 severe weather threat for Tuesday night into Wednesday morning, including Springfield, Missouri, a large swath of northwestern Arkansas and much of eastern Iowa, including Cedar Rapids, Davenport and Iowa City.
The severe weather threat spreads east into Wednesday, covering much of the Great Lakes and Ohio and Tennessee valleys.
