The NWS Storm Prediction Center has issued a

Alabama is the first of what likely will be several areas of severe
weather moving across this watch overnight. As a warm front moves
northward across the region, conditions will moisten and destabilize
considerably amidst strong vertical shear. The resulting parameter
space is one often associated with long-lasting, intense tornadoes
rated EF2 or greater.
The tornado watch area is approximately along and 100 statute miles
north and south of a line from 80 miles north of Mobile AL to 50
miles south of Columbus GA. For a complete depiction of the watch
see the associated watch outline update (WOUS64 KWNS WOU7).

tornadoes and severe thunderstorms in and close to the watch
area. Persons in these areas should be on the lookout for
threatening weather conditions and listen for later statements
and possible warnings.
