   0725 AM CST Tue Mar 03 2020

   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.
