   MESOSCALE DISCUSSION 0540
   NWS STORM PREDICTION CENTER NORMAN OK
   0335 PM CDT FRI MAY 09 2014

   AREAS AFFECTED...PARTS OF W CNTRL THRU NE GA INTO THE CAROLINA
   PIEDMONT

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 092035Z - 092230Z

   PROBABILITY OF WATCH ISSUANCE...5 PERCENT

   SUMMARY...A LINE OF THUNDERSTORMS MAY OVERSPREAD MUCH OF THE REGION
   DURING THE NEXT FEW HOURS.  GUSTY WINDS ARE POSSIBLE...BUT ACTIVITY
   IS EXPECTED TO REMAIN GENERALLY BELOW SEVERE LIMITS.

   DISCUSSION...THUNDERSTORMS HAVE GRADUALLY INTENSIFIED IN A NARROW
   LINE ALONG THE REMNANTS OF AN EASTWARD ADVANCING CONVECTIVE OUTFLOW
   BOUNDARY...WHICH APPEARS LIKELY TO PROGRESS INTO THE PIEDMONT OF THE
   CAROLINAS AND ACROSS MUCH OF THE REMAINDER OF NORTHERN GEORGIA
   THROUGH 23-00Z.  INFLOW OF BOUNDARY LAYER AIR CHARACTERIZED BY AT
   LEAST WEAK TO MODEST CAPE /500-1000 J PER KG/ SHOULD MAINTAIN
   ACTIVITY INTO EARLY EVENING.  AND IT IS NOT OUT OF THE QUESTION THAT
   PRECIPITATION LOADING AND THE DOWNWARD TRANSFER OF MOMENTUM COULD
   CONTRIBUTE TO LOCALLY STRONG SURFACE GUSTS.  DEEP LAYER MEAN FLOW
   ACROSS THIS REGION APPEARS GENERALLY ON THE ORDER OF 30 KT...ON THE
   SOUTHEASTERN PERIPHERY OF STRONGER CYCLONIC FLOW AHEAD OF LARGER
   SCALE UPPER TROUGHING TO THE WEST OF THE APPALACHIANS.  WHILE A
   COUPLE OF GUSTS COULD PERHAPS APPROACH SEVERE CRITERIA...
   ACTIVITY...IN GENERAL...IS EXPECTED TO REMAIN WELL BELOW SEVERE
   LIMITS.
