The unseasonable warmth across the South will go out with a bang on Monday--in the form of severe weather across the Tennessee Valley.
Southeastern Kentucky, central and eastern Tennessee, northeastern Mississippi, northern Alabama and northwestern Georgia are expected to become the target of violent thunderstorms on Monday afternoon.
The strongest of these thunderstorms will be capable of unleashing damaging winds, hail and downpours. A few tornadoes may also touch down and cause destruction.
The powerful thunderstorms will then shift to the south and east early on Monday night, rattling southwestern Virginia, western North Carolina, places just to the north and west of Atlanta and central Alabama.
Among the communities in Monday's threat zone include London, Ky., Nashville, Knoxville and Chattanooga, Tenn., Tupelo, Miss., Huntsville and Birmingham, Ala., and Rome, Ga.
Sparking Monday's severe weather will be a cold front, part of the storm that will soon return disruptive snow to parts of the Upper Midwest and Northeast, set to erase the April-like warmth encompassing the South this weekend.
Another cold front will bring a noticeable drop in temperatures from today to Sunday across the northern Tennessee Valley, Nashville included, and North Carolina. That front may be potent enough to trigger a handful of strong thunderstorms that may erupt along the Virginia/North Carolina border to southeastern Kentucky this afternoon.
Despite the cooler air's return, warmer air will quickly return for Monday west of the Appalachian Mountains and give rise to the violent thunderstorms.
Forecast Highs Across the South
The zone of thunderstorms will shift to the Florida Peninsula on Tuesday, but the severe weather danger will wane with some of the key ingredients needed for the development of violent thunderstorms absent.
