   ...SYNOPSIS...
   POTENT MID/UPPER LEVEL TROUGH WILL CONTINUE TO DIG AND AMPLIFY
   ACROSS THE TN VALLEY AND SOUTHEAST THROUGH TONIGHT. IN RESPONSE TO
   STRONG DPVA...DEEPENING SURFACE LOW WILL TRACK SEWD ACROSS GA TODAY
   BEFORE UNDERGOING RAPID INTENSIFICATION OFF THE SC COAST THROUGH
   LATE TONIGHT. ASSOCIATED COLD FRONT WILL SWEEP ESEWD FROM NRN/ERN AL
   ACROSS ALL OF GA AND NRN FL BY LATE EVENING. ELSEWHERE...LARGE UPPER
   RIDGE WILL BUILD ACROSS THE MIDWEST AND GREAT LAKES THIS PERIOD
   WHILE NEXT STRONG UPSTREAM TROUGH DEVELOPS ESEWD FROM THE CANADIAN
   ROCKIES TO THE NORTHERN PLAINS THROUGH WED.
   
   ...TN VALLEY...
   INCREASING SUN ANGLE WILL ALLOW FOR MODEST BOUNDARY LAYER HEATING
   AHEAD OF INTENSE MID LEVEL TROUGH DEVELOPING SEWD FROM WRN/MIDDLE TN
   ACROSS NRN/ERN AL OVER THE NEXT FEW HOURS. RUC POINT FCST SOUNDINGS
   ACROSS THIS REGION ADJUSTED FOR TEMPERATURES IN THE MID 50S F AND
   DEWPOINTS IN THE LOW 40S F YIELD MUCAPE VALUES OF 150-300 J/KG.
   LATEST SATELLITE IMAGERY WAS SHOWING AN EXPANDING AREA OF LOW-TOPPED
   CU SPREADING SEWD TOWARD THE AXIS OF GREATER HEATING OVER NRN AL.
   DESPITE VERY LIMITED LOW LEVEL MOISTURE...MAGNITUDE OF LARGE SCALE
   FORCING FOR ASCENT AND STRONG CLOUD BEARING SHEAR COULD SUPPORT
   ISOLD TO WIDELY SCATTERED LOW-TOPPED TSTMS WITH MARGINALLY SEVERE
   HAIL AND GUSTY WINDS THROUGH THE AFTERNOON.
   
   ...GA/SC...
   LACK OF GREATER LOW LEVEL MOISTURE REMAINS THE PRIMARY LIMITING
   FACTOR FOR SEVERE TSTM POTENTIAL ACROSS THESE AREAS. ALL SHORT TERM
   MODELS ARE IN VERY GOOD AGREEMENT AND FCST THE DEVELOPMENT OF STRONG
   LOW THROUGH MID LEVEL UPWARD VERTICAL MOTION NEAR SURFACE LOW AND
   COLD FRONT THROUGH THIS EVENING. THIS PROCESS MAY ALREADY BE
   UNDERWAY WITHIN BAROCLINIC LEAF CLOUD STRUCTURE DEVELOPING AHEAD OF
   THE LARGE SCALE TROUGH FROM ERN AL ACROSS CNTRL GA ATTM. WHILE
   INSTABILITY IS EXPECTED TO REMAIN QUITE MEAGER...DRY BOUNDARY LAYER
   AND STEEPENING LOW LEVEL LAPSE RATES WILL RESULT IN INVERTED-V SUB
   CLOUD PROFILES DEVELOPING ACROSS CNTRL ERN GA AND SRN SC. A FEW
   STRONG WIND GUSTS ARE POSSIBLE AS A FORCED LOW-TOPPED CONVECTIVE
   LINE MOVES INTO THESE AREAS FROM LATE AFTERNOON THROUGH EVENING.
   MARGINAL HAIL THREAT WILL ALSO EXIST WITH STRONGER CELLS FROM ERN GA
   ACROSS CNTRL SC AS VERY COLD MID LEVEL TEMPERATURES AND STRONG
   FORCING SPREAD OVER THESE AREAS THROUGH EARLY EVENING.
