   MESOSCALE DISCUSSION 0669
   NWS STORM PREDICTION CENTER NORMAN OK
   0127 PM CDT FRI MAY 23 2014

   AREAS AFFECTED...CAROLINAS

   CONCERNING...SEVERE THUNDERSTORM WATCH 178...

   VALID 231827Z - 232000Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 178
   CONTINUES.

   SUMMARY...STORM INITIATION HAS FAILED THUS FAR WITHIN WW 178...BUT
   IS STILL ANTICIPATED TO OCCUR ON AN ISOLATED BASIS BY 21Z. ISOLATED
   STORMS FORMING OVER THE HIGHER TERRAIN OF THE SRN APPALACHIANS WILL
   POSE A RISK FOR SEVERE HAIL AND LOCALLY DAMAGING WINDS AS WELL. AN
   ADDITIONAL WW WILL BE COORDINATED SHORTLY.

   DISCUSSION...LIMITED LOW-LEVEL CONVERGENCE AND RELATIVELY DRY
   BOUNDARY LAYER PROFILES HAVE LIKELY INHIBITED STORM DEVELOPMENT THUS
   FAR ACROSS MUCH OF THE CAROLINAS. THE EXCEPTION HAS BEEN OVER THE
   HIGHER TERRAIN WHERE ISOLATED TSTMS HAVE RECENTLY FORMED FROM MACON
   COUNTY NC TO PICKENS COUNTY SC. WITH A THERMODYNAMIC/KINEMATIC SETUP
   SIMILAR TO WW 178...AN UPSTREAM SEVERE TSTM WATCH ISSUANCE IS
   ANTICIPATED SOON. 

   WITH CONTINUED ROBUST SURFACE HEATING...IT STILL REMAINS PROBABLE
   THAT ISOLATED STORM DEVELOPMENT WILL EVENTUALLY OCCUR FARTHER E/SE
   ACROSS THE PIEDMONT AND COASTAL PLAIN.
