MESOSCALE DISCUSSION 2231
   NWS STORM PREDICTION CENTER NORMAN OK
   0707 AM CST WED DEC 26 2012
   
   AREAS AFFECTED...CENTRAL/ERN SC...SRN NC
   
   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 
   
   VALID 261307Z - 261430Z
   
   PROBABILITY OF WATCH ISSUANCE...60 PERCENT
   
   SUMMARY...TSTMS MAY INCREASE IN INTENSITY BY 16Z IN ADVANCE OF A
   COLD FRONT AND DEVELOPING AREA OF LOW PRESSURE. ENVIRONMENTAL
   CONDITIONS WILL FAVOR SUPERCELL AND BOWING STRUCTURES CAPABLE OF
   DAMAGING WINDS AND TORNADOES. A WW MAY BE NEEDED PRIOR TO 16Z.
   
   DISCUSSION...A WARM FRONT EXTENDED FROM JUST S OF MRH INLAND NEAR
   MYR AND TO A DEVELOPING SECONDARY AREA OF LOW PRESSURE OVER NRN GA.
   AS THE MORNING PROGRESSES THE WARM FRONT WILL LIFT NWD IN TANDEM
   WITH THE DEVELOPING SFC LOW...RESULTING IN A MODESTLY UNSTABLE AND
   STRONGLY SHEARED ATM OVER CENTRAL/ERN SC AND SRN NC. WIDESPREAD
   CLOUDS AND PRECIPITATION WILL PREVENT SUBSTANTIAL
   DESTABILIZATION...HOWEVER COOLING MID LEVEL TEMPERATURES AND FORCING
   FOR ASCENT ASSOCIATED WITH A STRONG SHORTWAVE WILL FOSTER THE
   DEVELOPMENT/INTENSIFICATION OF TSTMS DURING THE NEXT FEW HOURS OVER
   THE DISCUSSION AREA. VERY STRONG LOW-LEVEL WIND FIELDS HAVE RESULTED
   IN 0-1 KM SRH VALUES IN EXCESS OF 500 M2/S2...AND SUPERCELL
   STRUCTURES/BOWING SEGMENTS APPEAR INCREASINGLY LIKELY WITH A RISK OF
   TORNADOES AND DAMAGING WINDS. HIGH-RESOLUTION NUMERICAL GUIDANCE
   DEPICTS THIS SCENARIO UNFOLDING ACROSS THE DISCUSSION AREA THROUGH
   MIDDAY. CONVECTIVE TRENDS ARE BEING MONITORED FOR A WW PRIOR TO 16Z.
