AREAS AFFECTED...CNTRL AND NRN AL...SE TN AND NW GA

CONCERNING...TORNADO WATCH 132...134...

VALID 102043Z - 102215Z

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.
