AREAS AFFECTED...MIDDLE AND ERN TN...NRN AL...NRN AND CNTRL GA

CONCERNING...SEVERE THUNDERSTORM WATCH 382...

VALID 012004Z - 012200Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 382
CONTINUES.

SUMMARY...A WIND DAMAGE AND HAIL THREAT WILL BE POSSIBLE WITH THE
STRONGER THUNDERSTORMS THROUGH LATE AFTERNOON FROM PARTS OF MIDDLE
AND ERN TN SEWD INTO NRN AL AND NRN GA. THE THREAT COULD AFFECT
AREAS TO THE SOUTHEAST OF WW 382 LATER THIS AFTERNOON. A LOCAL
EXTENSION IN AREA COULD BECOME NECESSARY TO THE SOUTHEAST OF THE
CURRENT WATCH.

DISCUSSION...THE LATEST SFC ANALYSIS SHOWS A CORRIDOR OF LOW-LEVEL
MOISTURE EXTENDING SEWD FROM THE OZARKS INTO NRN MS...NRN AL AND WRN
GA WHERE SFC DEWPOINTS ARE IN THE LOWER TO MID 70S F. MODERATE
INSTABILITY IS ANALYZED ALONG THIS CORRIDOR WHERE LAPSE RATES HAVE
STEEPENED THIS AFTERNOON. SCATTERED STRONG THUNDERSTORMS ARE ONGOING
ALONG THE INSTABILITY GRADIENT IN NRN AL AND ERN TN. THIS CONVECTION
SHOULD CONTINUE TO FOLLOW THE GRADIENT SEWD ACROSS THE SERN PART OF
WW 382 OVER THE NEXT COUPLE OF HOURS. THE WSR-88D VWP IN THE ATLANTA
METRO SHOWS ABOUT 25 KT OF DEEP-LAYER SHEAR SUGGESTING ENOUGH SHEAR
EXISTS TO THE SOUTHEAST OF THE WATCH TO HELP KEEP STORMS ORGANIZED.
AS SFC HEATING CONTINUES AND INSTABILITY INCREASES OVER THE NEXT FEW
HOURS...THE SEVERE THREAT SHOULD CONTINUE WITH A BOWING LINE SEGMENT
IN FAR NRN AL AND WITH CELLS FURTHER TO THE SOUTHEAST THAT ARE
MOVING INTO NW GA.
