   0355 PM CDT TUE JUL 14 2015

   AREAS AFFECTED...NRN MS/AL/GA...WRN SC

   CONCERNING...SEVERE POTENTIAL...SEVERE THUNDERSTORM WATCH LIKELY 

   VALID 142055Z - 142200Z

   PROBABILITY OF WATCH ISSUANCE...95 PERCENT

   SUMMARY...TSTM ACTIVITY ACROSS TN IS EXPECTED TO CONTINUE SWD INTO
   NRN MS/AL/GA AND NW SC WITH A CONTINUED SVR THREAT. A SVR TSTM WATCH
   WILL BE NEEDED SHORTLY.

   DISCUSSION...LINE OF STRONG TO SEVERE TSTMS STRETCHES FROM FAR NE AR
   ACROSS TN WITH RECENT RADAR INDICATIONS SUGGESTING UPSCALE GROWTH IS
   UNDERWAY. A CONCENTRATED DAMAGING WIND THREAT WILL LIKELY EXIST WITH
   THE LINE OF STORMS MOVING SEWD ACROSS THE AR/TN BORDER. RECENT
   FORWARD SPEED ON THIS SYSTEM IS AROUND 50 KT. OTHER PORTION OF THE
   LINE HAS EXHIBITED SLOWER SEWD MOTION BUT THE CONTINUED UPSCALE
   GROWTH AS WELL AS A MODERATE INCREASE IN NWLY FLOW WILL LIKELY
   ACCELERATE THIS PORTION OF THE LINE OF STORMS AS WELL. AS SUCH...SVR
   THREAT WILL CONTINUE FARTHER S IN NRN MS/AL/GA AND WRN SC WITH A SVR
   TSTM WATCH NEEDED SHORTLY TO COVER THIS THREAT.
