Areas affected...southern Alabama into west-central/south-west
Georgia

Concerning...Severe potential...Watch possible=20

Valid 210917Z - 211015Z

Probability of Watch Issuance...40 percent

SUMMARY...Thunderstorms are developing in southern Alabama this
morning. These storms are more isolated/cellular than those farther
northeast in Georgia. The environment ahead these storms will remain
sufficient for transient supercell-like structures.

DISCUSSION...Thunderstorms have developed this morning to the south
and west of an existing, long-lived line of thunderstorms. These
developing thunderstorms exist in a slightly better thermodynamic
environment than those storms farther northwest. Here, most-unstable
CAPE of nearly 2000 J/kg and deep layer shear of 30-35 knots will
support at least transient supercell-like structures this morning
capable of strong, gusty winds, and perhaps a brief tornado or two.
