Severe Storms Shift Into Mississippi and Alabama With Isolated Tornado and Flood Risks

Forecasters expect coverage to shrink as instability eases into the evening.

Overview

Tornado Watch 641 remains in effect for southeastern Mississippi into central Alabama, where brief tornadoes and localized damaging winds are still possible.
SPC notes storms have become more transient with only periodic low‑level rotation, and a weakening trend is anticipated with the loss of daytime heating.
WPC warns of training cells producing 1 to 2+ inches per hour and pockets of flash flooding, with particular concern near the Tuscaloosa–Birmingham corridor.
Overnight, a maturing squall line and embedded supercells advanced from Louisiana into Mississippi under Watches 639–640, bringing line‑embedded circulations and strong gusts.
Meteorologists attribute the lingering risks to strong shear and a low‑level jet interacting with outflow boundaries and a warm‑frontal zone, even as storm coverage becomes more isolated.
