A large area of severe thunderstorms is forecast into Tuesday night and will overlap areas in the Ohio, Tennessee and middle Mississippi valleys that were hit by deadly and damaging storms, forecasters say.

As a storm system approached Jackson, in Southeastern Kentucky, on May 16, a few individuals agreed to work double shifts to make sure timely warnings continued during the overnight hours, said Tom Fahy, legislative director for the National Weather Service Employees Organization.

National Weather Service officials place most of KMAland in a slight risk for severe weather, with an enhanced risk south of the Iowa-Missouri border. While the full gamut of severe weather is possible, Weathereye Meteorologist Kara Foster says hail is the main threat.

An outbreak of severe weather will continue for one more day as it brings the risk of strong tornadoes, widespread damaging winds, hail and flooding rain to portions of the Midwest and South on Tuesday.
