Tornadoes, severe storms slam America's heartland

A tornado outbreak is unfolding Wednesday for parts of the lower Mississippi Valley into the mid-South and lower Ohio Valley, including the threat of multiple long-track EF-3 or stronger tornadoes. NOAA's Storm Prediction Center (SPC) upgraded portions of Arkansas, Missouri, Illinois, Kentucky, Tennessee and Mississippi to a rare Level 5 out of 5 "high risk" of severe weather. A massive tornado was spotted by FOX Weather Storm Tracker Brandon Copic as it roared near Lake City, Arkansas. Authorities issued a Tornado Emergency – the most dire of tornado alerts – for towns in the path of the storm, such as Leachville and Monette. Copic urged people in the warning area to get to safety.
