   Mesoscale Discussion 0221
   NWS Storm Prediction Center Norman OK

   Areas affected...the central Carolinas into southeast Virginia

   Concerning...Severe potential...Watch unlikely 

   Valid 151936Z - 152200Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Storm coverage should gradually increase over the next few
   hours, and a few may produce locally strong wind gusts.

   DISCUSSION...Heating has contributed to around 500 J/kg MUCAPE from
   GA into SC, with lesser values northeastward into VA. This zone of
   relatively warm air exists in advance of a cold front, now moving
   into central GA and across the western Carolinas where a band of
   precipitation exists ahead of the front.

   Visible imagery show increasing CU fields as well as a few weak
   thunderstorms along the front especially from GA into SC where
   heating is strongest. Forecast soundings show a warm layer below 700
   mb which is likely contributing to slow storm growth.

   As heating persists, a few strong storms are expected to develop.
   Generally long, straight hodographs suggest cellular activity, but
   mixed storm mode is possible as well with line segments. Given
   southwesterly 850 mb winds of 35-45 kt, some storms may produce
   marginally severe wind gusts. Small hail cannot be ruled out with
   the strongest cores.
