   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 132...134...CONTINUES.
   
   THREAT FOR STRONG TORNADOES CONTINUES FROM N CNTRL THROUGH NE AL
   INTO SE TN AND NW GA. THREAT WILL CONTINUE TO SPREAD EAST INTO THE
   EVENING. THE STRONGER STORMS WILL ALSO BE CAPABLE OF PRODUCING LARGE
   HAIL AND DAMAGING WIND. 
   
   LINE OF MOSTLY DISCRETE SUPERCELLS FROM SE TN INTO NE AND N CNTRL AL
   IS ADVANCING EAST AND BEGINNING TO AFFECT NW GA. LARGEST LOW LEVEL
   HODOGRAPHS EXIST FROM NE AL...SE TN INTO NW GA WHERE BOUNDARY LAYER
   WINDS REMAIN BACKED TO SLY WITHIN AN AREA OF LARGER PRESSURE FALLS.
   VISIBLE IMAGERY CONTINUES TO SHOW GROWING CUMULUS ALONG SW-NE
   ORIENTED CLOUD STREETS OVER CNTRL AND N CNTRL AL WHERE TEMPERATURES
   HAVE WARMED TO NEAR 80 WITHIN THE MODERATELY UNSTABLE WARM SECTOR.
   STORMS THAT DEVELOP IN THIS REGION WILL LIKELY ORGANIZE INTO
   SUPERCELLS AS THEY MOVE EAST THROUGH THE REMAINDER OF AL AND INTO
   GA. SIZE OF LOW LEVEL HODOGRAPHS AND STRONG BULK SHEAR WILL MAINTAIN
   A THREAT FOR LONG LIVED SUPERCELLS CAPABLE OF PRODUCING STRONG
   TORNADOES AND VERY LARGE HAIL AS ACTIVITY DEVELOPS EAST NEXT FEW
   HOURS.
