   MESOSCALE DISCUSSION 0842
   NWS STORM PREDICTION CENTER NORMAN OK
   0510 PM CDT THU JUN 05 2014

   AREAS AFFECTED...PARTS OF NRN/E CNTRL ALABAMA INTO NW/W CNTRL GA

   CONCERNING...SEVERE THUNDERSTORM WATCH 232...

   VALID 052210Z - 052345Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 232
   CONTINUES.

   SUMMARY...AT LEAST WESTERN PORTIONS OF THE ATLANTA METRO AREA MAY BE
   IMPACTED BY STRONG/SEVERE STORMS WITH THE RISK FOR POTENTIALLY
   DAMAGING WIND GUSTS AND FREQUENT CLOUD TO GROUND LIGHTNING BY
   01-02Z.

   DISCUSSION...CONSIDERABLE WEAKENING OF THE ONGOING MESOSCALE
   CONVECTIVE SYSTEM HAS OCCURRED DURING THE PAST HOUR OR SO. 
   SOUTHEASTWARD MOTION OF THE SURFACE COLD POOL APPEARS TO HAVE SLOWED
   AS IT ADVANCES INTO A PROGRESSIVELY WEAKER DEEP LAYER NORTHWESTERLY
   MEAN FLOW REGIME.  WESTERLY LOW-LEVEL FLOW AHEAD OF THE COLD POOL
   DOES NOT APPEAR OPTIMAL FOR SYSTEM MAINTENANCE.  HOWEVER...THE GUST
   FRONT ENCOUNTERS THE WESTERN FLANK OF A REMNANT OUTFLOW BOUNDARY
   NEAR/ SOUTHEAST OF GADSEN AROUND 00Z...ENHANCED CONVERGENCE COULD
   STILL SUPPORT INTENSIFYING CONVECTIVE DEVELOPMENT.  IF THIS
   OCCURS...IT SEEMS LIKELY TO SUBSEQUENTLY TAKE A MORE SOUTHEASTWARD
   TURN...JUST TO THE COOL SIDE OF THE OUTFLOW BOUNDARY...WHERE A MOIST
   LOW-LEVEL AIR MASS IS CONTRIBUTING MODERATELY LARGE CAPE.  AT LEAST
   WESTERN PORTIONS OF THE ATLANTA METRO AREA MAY BE IMPACTED BY
   STORMS...WITH POTENTIAL FOR STRONG WIND GUSTS AND FREQUENT CLOUD TO
   GROUND LIGHTNING BY 01-02Z.
