   0240 PM CDT Thu Sep 12 2024

   Areas affected...Parts of central into south AL

   Concerning...Severe potential...Watch possible 

   Valid 121940Z - 122215Z

   Probability of Watch Issuance...40 percent

   SUMMARY...Some tornado threat could evolve this afternoon.

   DISCUSSION...Persistent cloudiness has thus far limited
   destabilization north of a warm front draped across south AL.
   However, some modest destabilization (with MLCAPE approaching or
   exceeding 500 J/kg) will be possible from south to north this
   afternoon as the warm front moves slowly northward. One persistent
   cell is ongoing northeast of Montgomery, and additional low-topped
   supercell development will be possible along/north of the warm front
   through the afternoon. 

   Stronger low-level flow/shear will gradually shift northward in
   conjunction with the warm front through the afternoon, but will
   generally remain favorable, with 0-1 km SRH generally in the 150-300
   m2/s2 range in areas where modest destabilization is possible. Some
   tornado threat could evolve with time this afternoon, contingent on
   the development of additional low-topped supercells. Observational
   trends will be monitored regarding the need for a Tornado Watch.
