Severe thunderstorms, including tornadoes, are possible across the southern United States on Wednesday.
Widespread showers and storms are expected from the Midwest to the Southeast starting on Tuesday, but the chances for severe weather will increase on Wednesday.
By Wednesday afternoon, severe weather is likely in eastern Arkansas and northeastern Louisiana into Mississippi, Alabama and Tennessee.
Showers and storms in Texas will move to the east into the Lower Mississippi Valley and Southeast by the afternoon.
Unstable air, high humidity, and upper-level winds will further enhance the threat for severe weather with the ongoing showers and increase the likelihood of additional storm development.
The threat for some tornadoes extends from eastern Texas into Georgia, South Carolina, Tennessee and Kentucky.
Damaging winds are also possible in the area, with a higher risk of strong gusts across Mississippi, Alabama and Tennessee.
The same areas could see some large hail if any strong storms develop.
A smaller area could see flash flooding from any storms that pop up, but there's a higher chance for flooding across Tennessee, including Nashville and Knoxville.
Later in the week, the same area has the potential to see severe storms on New Year's Day.
Another strong low-pressure system looks to track toward the Mississippi Valley, providing severe chances Saturday afternoon.
