There is a threat for severe weather across East Texas, most of Louisiana and Mississippi, all of Northern Alabama, and sections of Central Alabama tomorrow through tomorrow night/early Sunday. The threat will shift east during the day Sunday.
A storm system is going to bring a trailing cold front east tomorrow.
Tomorrow morning and early tomorrow afternoon a squall line will evolve across East Texas along the front. The squall will advance east during the afternoon tomorrow night/early Sunday in tandem with the front, working through East Texas tomorrow afternoon/evening, and Louisiana and Mississippi late tomorrow evening/overnight, and into Northern and Central portions of Alabama during the first half of the day Sunday.
The squall line might make it into the Western Florida Panhandle and the remainder of South/Central Alabama later during the day Sunday, but would be breaking up as lift begins to decrease.
Some additional storms will likely form along coastal Texas, South Louisiana, South Mississippi, South Alabama, areas of Central Alabama, and the Western Florida Panhandle along and ahead of the front later Sunday.
Tomorrow
Severe threat: There will be efficient instability, lift, and wind shear (the latter courtesy of a strong low-level jet stream) for a low-end (marginal) to enhanced severe threat.
Placement: The greatest threat will be in the “enhanced” risk area and “slight” risk area, where scattered to numerous severe storms will be possible. Isolated severe storms will be possible in the “marginal” risk area.
Threats: Large hail, damaging straight line winds, and isolated tornadoes.
Sunday
Severe threat: The overall threat for severe weather will decrease. Lift will also decrease. However, instability and shear will allow for a low-end (marginal) threat for a few isolated severe storms.
Placement: Southeast Louisiana, South Mississippi, South Alabama, and part of Central Alabama.
Threats: Strong wind gusts and possibly an isolated tornado or two.
