   AREAS AFFECTED...SRN MS...SRN AL...WRN FL PANHANDLE
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 140554Z - 140730Z
   
   A MARGINAL THREAT FOR WIND DAMAGE AND HAIL WILL LIKELY CONTINUE FOR
   A FEW MORE HOURS ACROSS SRN MS..SRN AL AND THE WRN FL PANHANDLE.
   HOWEVER...THE THREATS ARE EXPECTED TO REMAIN TOO ISOLATED FOR WW
   ISSUANCE.
   
   A LINE OF STRONG THUNDERSTORMS IS CURRENTLY ONGOING JUST AHEAD OF A
   COLD FRONT WITH AN AXIS OF MODERATE INSTABILITY EXTENDING SWD FROM
   THE LINE ACROSS SW AL AND SRN MS. MESOANALYSIS ESTIMATES MLCAPE
   VALUES ALONG THIS CORRIDOR TO RANGE FROM 500 TO 1500 J/KG SUGGESTING
   THE INSTABILITY SHOULD BE ENOUGH TO KEEP THE LINE SUSTAINED SEWD
   ACROSS THE REMAINDER OF SRN AL AND POSSIBLY INTO THE WRN FL
   PANHANDLE. THE MOBILE WSR-88D VWP SHOWS 40 KT OF 0-6 KM SHEAR WITH
   SUBSTANTIAL DIRECTIONAL SHEAR IN THE LOWEST 1.5 KM. THIS ALONG WITH
   25-35 KT OF FLOW AT 850 TO 700 MB MAY PROVIDE SUPPORT FOR A MARGINAL
   WIND DAMAGE THREAT WITH SHORT LINE-SEGMENTS THAT OBTAIN A BOWING
   STRUCTURE. HAIL MAY ALSO OCCUR WITH THE MORE INTENSE CELL ELEMENTS
   WITHIN THE LINE.
