   Mesoscale Discussion 1157
   NWS Storm Prediction Center Norman OK
   0452 PM CDT Fri Jun 06 2025

   Areas affected...portions of central and northern Alabama into
   northern Georgia

   Concerning...Severe potential...Watch unlikely 

   Valid 062152Z - 062315Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A few strong wind gusts will remain possible through the
   rest of the afternoon. Given the isolated nature of the severe
   threat, a WW issuance is not expected.

   DISCUSSION...Several strong pulse-cellular and multicellular storms
   have matured over the past few hours given strong heating of a moist
   boundary layer. 7-8 C/km boundary-layer lapse rates atop 70+ F
   surface dewpoints are contributing to 1500-3000 J/kg MLCAPE. While
   the warm sector is overspread by only 25-35 kts of effective bulk
   shear, these conditions should support continued organization of
   multicells with wet downburst potential. The severe threat, however,
   should be isolated, precluding a WW issuance.
