The National Weather Service office in Paducah says the entire region is included in a slight risk of severe thunderstorms for Wednesday.
An “enhanced” risk of severe storms covers most of western Kentucky, all of western Tennessee, and parts of extreme southern Illinois and southeast Missouri.
The weather service says the greatest risk is for intense thunderstorms (supercells) to develop around mid-day Wednesday west of the Land Between the Lakes, moving to the northeast during the middle and late afternoon.
The area has the potential for thunderstorms to produce damaging winds and large hail, as well as isolated tornadoes.
The NWS the threat could extend until around 7:00 pm.
Some storms are expected to develop tonight in southeast Missouri and western Kentucky that are not as severe.
