   Mesoscale Discussion 0157
   NWS Storm Prediction Center Norman OK
   1125 AM CST Fri Feb 23 2024

   Areas affected...northern Florida into southeast Georgia and
   southern South Carolina

   Concerning...Severe potential...Watch unlikely 

   Valid 231725Z - 232030Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A gradual increase in convective coverage is possible over
   the next several hours, and localized strong gusts may occur.

   DISCUSSION...A strong upper trough with cooling aloft continues to
   rapidly overspread the region, with a cold front now extending from
   central SC into the FL Panhandle. A narrow plume of warming
   temperatures and dewpoints to around 60 F extend from the FL
   Panhandle across southeast GA and toward southern SC, and is
   contributing to up to 500 J/kg SBCAPE.

   Modified soundings from the area depict generally shallow storm
   potential, however, if cooling aloft can remove the midlevel warm
   layer prior to the cold front moving offshore, a brief period may
   exist for deeper convection. Given the strong deep-layer wind
   fields, but generally weak instability, localized wind damage would
   appear to be the main concern.
