   Mesoscale Discussion 2160
   NWS Storm Prediction Center Norman OK
   1245 PM CDT Sun Sep 17 2023

   Areas affected...Southeast Georgia into southwest South Carolina

   Concerning...Severe potential...Watch unlikely 

   Valid 171745Z - 171945Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Damaging wind gusts (45-60 mph) are possible this
   afternoon as storm coverage and intensity gradually increases. A
   watch is not expected.

   DISCUSSION...Temperatures have warmed into the upper 80s F in
   southeast Georgia early this afternoon. The boundary layer has
   largely become uncapped and showers/thunderstorms have begun to form
   within this area of stronger heating with perhaps some additional
   support from weak pre-frontal convergence. Into southwestern South
   Carolina, temperatures have also warmed into the low 80s behind
   early day convection. With additional surface heating, storms should
   gradually intensify this afternoon as MLCAPE increases to 1000-1500
   J/kg. Enhanced mid-level winds (effective shear of around 30 kts)
   from a trough moving through the southeast will help storms
   organize. The primary hazard will be isolated damaging wind gusts.
   The tornado threat with this activity will be low given the veered
   surface winds and consequent weak low-level SRH. Additional storms
   along the front will pose a similar threat as they move into the
   region, though shear parallel to the boundary will likely mean a
   more linear storm mode.
