   MESOSCALE DISCUSSION 1156
   NWS STORM PREDICTION CENTER NORMAN OK
   0155 PM CDT WED JUN 24 2015

   AREAS AFFECTED...MUCH OF MISSISSIPPI AND SMALL PARTS OF SOUTHEASTERN
   AND EASTERN LOUISIANA

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 241855Z - 242000Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...SCATTERED THUNDERSTORMS HAVE DEVELOPED ACROSS THE
   DISCUSSION AREA WITH DAMAGING DOWNBURST WINDS POSSIBLE IN/NEAR THE
   STRONGEST ACTIVITY.  WW ISSUANCE IS NOT CURRENTLY EXPECTED...BUT
   TRENDS WILL BE MONITORED.

   DISCUSSION...A SMALL CLUSTER OF STRONG TO SEVERE STORMS HAVE
   DEVELOPED IN SOUTHEASTERN MISSISSIPPI NEAR THE PINE BELT
   REGION...WITH ADDITIONAL DEVELOPMENT POSSIBLE IN THE REMAINDER OF
   NORTHERN AND CENTRAL MISSISSIPPI OVER THE NEXT 1-2 HOURS.  THE
   ACTIVITY IN SOUTHEASTERN MISSISSIPPI HAS BEGUN TO FORWARD PROPAGATE
   ALONG THE LEADING EDGE OF A CONVECTIVELY-INDUCED SWWD-MOVING COLD
   POOL...WHICH MAY LOCALLY ENHANCE THE DAMAGING WIND THREAT IN
   DOWNSTREAM AREAS ACROSS SOUTHERN MISSISSIPPI.  AN ADDITIONAL
   BOUNDARY THAT WILL LIKELY SUPPORT/FOCUS SCATTERED THUNDERSTORM
   DEVELOPMENT IS CURRENTLY LOCATED FROM NEAR MEM TO NEAR GWO TO NEAR
   JAN...WITH ADDITIONAL DEVELOPMENT LIKELY ALONG THE HWY 82 CORRIDOR. 
   TEMPERATURES RISING THROUGH THE 90S ALONG WITH MID-70S DEWPOINTS
   CONTINUE TO SUPPORT STRONG INSTABILITY...WHICH WILL FURTHER SUPPORT
   A DAMAGING WIND THREAT DESPITE MEAGER DEEP SHEAR FOR STORM
   ORGANIZATION.  TRENDS WILL BE MONITORED...ALTHOUGH A WW IS NOT
   CURRENTLY ANTICIPATED DUE TO THE ISOLATED NATURE OF THE THREAT.
