Areas affected...central Alabama into west-central Georgia

Concerning...Tornado Watch 38...

Valid 031325Z - 031530Z

The severe weather threat for Tornado Watch 38 continues.

SUMMARY...A cluster of storms may continue to pose a tornado or
damaging wind threat over the next several hours from central
Alabama into west-central Georgia.

DISCUSSION...A slow-developing, but long-lived cluster of storms
continues to sporadically pose a tornado risk over central Alabama
this morning. These storms formed in association with warm/moist
advection, and persist with the aid of substantial deep-layer wind
shear and sufficient instability. 12Z soundings from the region
suggest MLCAPE on the order of 500 J/kg. Objective analysis further
indicates that instability decreases south of the area as
temperatures aloft are warmer. However, pockets of heating may
eventually develop later this morning and aid destabilization.
Effective SRH over 200 m2/s2 is also forecast to remain for much of
the day. As such, a brief tornado or damaging wind gusts remain
possible within this east-west corridor.
