THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 332
CONTINUES.

THREAT FOR ISOLATED STRONG TO DAMAGING WIND GUSTS WILL CONTINUE NEXT
FEW HOURS...MAINLY WITH STORMS MOVING SEWD THROUGH PARTS OF WRN AND
MIDDLE TN. STORMS IN SERN TN AND NRN AL ARE MOVING OUT OF WW 332.
ALTHOUGH A MODEST THREAT FOR ISOLATED STRONG WIND GUSTS WILL
CONTINUE WITH THIS ACTIVITY NEXT FEW HOURS OVER NRN GA AND NRN
AL...OVERALL THREAT DOES NOT APPEAR SUFFICIENT TO WARRANT ANOTHER WW
AT THIS TIME.

LEADING CLUSTER OF STORMS STRETCHES FROM NWRN GA THROUGH NRN AL WITH
TRAILING OUTFLOW BOUNDARY LAGGING NWWD THROUGH WRN PARTS OF MIDDLE
TN. FARTHER UPSTREAM A LINE OF STORMS IS MOVING SEWD AT 25 KT
THROUGH NWRN TN AND SWRN KY. FULL SUN IS PERMITTING THE BOUNDARY
LAYER TO DESTABILIZE OVER MIDDLE TN IN WAKE OF LEADING CONVECTIVE
CLUSTER. LATEST OBJECTIVE ANALYSIS SHOWS A RESERVOIR OF 2500-3000
J/KG MLCAPE WITH WEAK CAP W OF THE OUTFLOW BOUNDARY FROM WRN MIDDLE
TN THROUGH ALL OF WRN TN. STORMS ARE EMBEDDED WITHIN 20-25 KT NWLY
FLOW ALOFT AND CONVERGENCE ALONG THE LEADING GUST FRONT SHOULD
CONTINUE TO PROMOTE A FORWARD PROPAGATING MCS NEXT FEW HOURS. THE
THREAT FOR LARGE HAIL WILL REMAIN LIMITED BY WARM AIR ALOFT AND WEAK
LAPSE RATES. HOWEVER...ISOLATED STRONG TO DAMAGING WIND GUSTS WILL
REMAIN POSSIBLE AS ACTIVITY DEVELOPS SEWD.
