SPC MESOSCALE DISCUSSION 1325 FOR CNTRL/SRN GA...PARTS OF SRN AL
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
   
   VALID 062240Z - 070100Z
   
   CONVECTIVE TRENDS ARE BEING MONITORED.  
   
   THUNDERSTORM ACTIVITY HAS BECOME INCREASINGLY CONCENTRATED DURING
   THE PAST HOUR IN AREA OF EASTERN GEORGIA BETWEEN AUGUSTA/MACON/AND
   SAVANNAH.  THIS IS WHERE LOW-LEVEL CONVERGENCE HAS BECOME FOCUSED
   NEAR 1013 MB SURFACE LOW...AND INSTABILITY IS MAXIMIZED ALONG
   EASTERN/SOUTHERN PERIPHERY OF LOW-LEVEL THERMAL RIDGE IN THE LEE OF
   THE SOUTHERN APPALACHIANS.  LOWER/MID 70S SURFACE DEW POINTS HAVE
   CONTRIBUTED TO MEAN MIXED LAYER CAPE IN EXCESS OF 2000 J/KG...
   SUPPORTIVE OF VIGOROUS UPDRAFTS WITH LOCALLY VERY HEAVY RAIN AND
   PERHAPS SOME MARGINAL SEVERE HAIL.  SUFFICIENT DRY AIR IS PRESENT
   FOR ISOLATED DOWNBURSTS IN WEAK SHEAR ENVIRONMENT...WITH WEAK
   SURFACE MESO HIGH/COLD POOL LIKELY TO GRADUALLY EVOLVE DURING THE
   NEXT HOUR OR TWO.  AIDED BY 20 KT NORTHEASTERLY STEERING FLOW...
   GUST FRONT ASSOCIATED WITH LOOSELY ORGANIZED CLUSTER OF STORMS IS
   EXPECTED TO DEVELOP WEST SOUTHWESTWARD ALONG INSTABILITY AXIS
   THROUGH MACON AND COLUMBUS...WHERE SURFACE TEMPERATURES ARE IN THE
   UPPER 90S.  LEADING EDGE OF OUTFLOW MAY SPREAD INTO AREAS OF
   ALABAMA NORTH OF TROY IN THE 07/02Z-03Z TIME FRAME.
