   Mesoscale Discussion 0231
   NWS Storm Prediction Center Norman OK
   1141 AM CDT Sat Apr 07 2018

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

   Concerning...Severe potential...Watch possible 

   Valid 071641Z - 071845Z

   Probability of Watch Issuance...40 percent

   SUMMARY...A gradual increase in storm intensity is possible across
   northern Florida into southern Georgia over the next several hours,
   with at least a localized damaging wind or brief tornado threat.

   DISCUSSION...Destabilization is slowly occurring ahead of a
   pre-frontal convective band extending from the eastern FL Panhandle
   into southern GA. Storms on the leading edge of this band have shown
   relative strength at times with transient areas of rotation with
   some of the cells. Other deepening showers are over northern FL
   where temperatures are approaching 80 F.

   Winds aloft will generally increase throughout the day, with
   gradually veering low-level winds. The increasing speed shear should
   maintain favorable hodographs supporting a few supercells, as well
   as a few small bows. VWPs and forecast soundings generally indicate
   effective SRH values on the order of 100-200 m2/s2 today.
