   AREAS AFFECTED...NRN GA AND WRN SC
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 66...
   
   VALID 270443Z - 270545Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 66
   CONTINUES.
   
   OVERALL SEVERE WEATHER THREAT...DAMAGING WINDS AND HAIL...REMAINS
   MAINLY ACROSS WRN AND SRN PARTS OF WW 66.  THE NERN EXTENT OF THIS
   WATCH HAS BEEN CONVECTIVELY OVERTURNED...LIMITING THE THREAT FOR
   SEVERE OVERNIGHT...SUCH THAT AREA WILL LIKELY BE REMOVED FROM THE
   WATCH BY THE LOCAL WFO.
   
   AT 04Z...SURFACE ANALYSIS SHOWED AN AREA OF LOW PRESSURE OVER EAST
   CENTRAL/NERN AL /INVOF ANB/ WITH A WARM FRONT EXTENDING ESEWD
   THROUGH CENTRAL GA TO FAR SRN SC.  STRONG SURFACE BASED INHIBITION N
   OF THE WARM FRONT SUGGESTS THE ORGANIZED LINES/BOWING SEGMENTS
   TRACKING SEWD THROUGH WRN AND SRN PARTS OF WW 66 ARE LIKELY
   ELEVATED.  DESPITE THIS FACT...EXPANDING AND COOLING CLOUD TOPS PER
   IR SATELLITE IMAGERY OVER NERN AL/NWRN GA SUGGESTS AN MCS IS
   POTENTIALLY DEVELOPING.  THIS WITH AN ATTENDANT COLD POOL AND SEWD
   MOVEMENT OF THE LEADING LINE OF STORMS AT 35-40 KT AND A 50 KT SWLY
   LLJ EXTENDING INTO CENTRAL GA SUGGESTS SOME OF THIS HIGHER MOMENTUM
   AIR COULD REACH THE SURFACE OVERNIGHT.  THIS THREAT FOR DAMAGING
   WINDS WOULD BE ALONG THE SRN TIER OF WW 66...AND POTENTIAL INTO SRN
   SC/EAST CENTRAL GA WHERE ACTIVITY WOULD BECOME CLOSER TO SURFACE
   BASED AS IT REACHES THIS PORTION OF THE WARM FRONT AFTER 07Z.
