   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 11 CONTINUES.
   
   ALTHOUGH MOST FAVORABLE PORTION OF WARM SECTOR IS SHRINKING OVER
   E-CENTRAL THROUGH SWRN AL...TORNADO THREAT CONTINUES ALONG AND W OF
   WARM FRONT...AND ALONG AND E OF MAIN TSTM BAND.  WW MAY BE CLEARED
   BEHIND THAT BAND.  AREAS OF SRN/ERN AL AND PERHAPS WRN GA AHEAD OF
   PRESENT WW WILL BE MONITORED FOR POSSIBILITY OF ADDITIONAL WW
   ISSUANCE.
   
   AS OF 12Z...WARM FRONT WAS DRAWN FROM FL PANHANDLE BETWEEN
   CEW-MAI...NWD ACROSS ERN AL JUST W OF DHN-AUO LINE.  THIS BOUNDARY
   MAY REACH GA BORDER REGION BEFORE BEING OVERTAKEN BY PRIMARY
   CONVECTIVE BAND...WHICH WAS EVIDENT AT 12Z FROM NEAR ANB SWWD ACROSS
   SWRN MS TO NEAR PTN IN LA.  CORRIDOR OF 250-800 J/KG MLCAPE REMAINS
   OVER WARM SECTOR FROM E-CENTRAL AL SWWD ACROSS SERN LA.  50-60 KT
   EFFECTIVE SHEAR MAGNITUDES AND 400-700 J/KG EFFECTIVE SRH REMAIN
   COMMON IN AL WARM SECTOR IN SUPPORT OF SUPERCELL POTENTIAL...AND
   SIMILAR VALUES SHOULD BE MAINTAINED THROUGH AT LEAST 15Z AHEAD OF
   MAIN BAND.
   
   LOW-LEVEL SRH...DEEP-LAYER SHEAR AND LOW-LEVEL CONVERGENCE EACH
   WEAKEN CONSIDERABLY FROM NEAR MS/AL BORDER SWWD BECAUSE OF
   RELATIVELY VEERED SFC FLOW.  HOWEVER...AS CONFLUENCE LINE CONTINUES
   MOVING INTO FAVORABLY MOIST AIR MASS ALONG MS/AL GULF
   COAST...CONDITIONAL THREAT WILL LINGER FOR SVR IN THAT AREA...MAINLY
   IN FORM OF DAMAGING GUSTS.
