   CONCERNING...TORNADO WATCH 142...143...
   
   VALID 150009Z - 150215Z

   FROM FAR SERN AL INTO SWRN AND PERHAPS CNTRL GA.  ELSEWHERE...THE

   COMPLEX MCS IS ONGOING AS OF 2355Z FROM NERN GA SWWD INTO SRN AL AND
   THE WRN FL PNHDL WITH THE MOST INTENSE STORMS /HP SUPERCELLS/ OVER
   RUSSELL/BARBOUR AND COFFEE/DALE COUNTIES IN SERN AL.  LATEST
   MESOANALYSIS INDICATES THAT RELATIVELY STRONG PRESSURE FALLS ARE
   OCCURRING AHEAD OF THESE MORE INTENSE STORMS OVER SERN AL WITH
   LATEST FT. RUCKER SHOWING A RESULTANT INCREASE IN LOW-LEVEL SHEAR
   OVER THE LAST HOUR.  INDEED...KINEMATIC ENVIRONMENT HAS BECOME QUITE
   FAVORABLE FOR TORNADIC SUPERCELLS GIVEN THE MOIST/UNSTABLE BOUNDARY
   LAYER WITH 0-1 KM SRH OF 300-350 M2/S2 AND EFFECTIVE BULK SHEARS OF
   55-60 KT.
   
   DESPITE THE RELATIVELY COMPLEX NATURE OF ONGOING STORMS...POTENTIAL
   WILL EXIST FOR EMBEDDED LONG LIVED SUPERCELLS CAPABLE OF
   TORNADOES...SOME OF WHICH COULD BE STRONG.  THIS MORE FAVORABLE
   ENVIRONMENT APPEARS TO BE BOUND BY WARM FRONT /CURRENTLY EXTENDING
   FROM INTERSECTION WITH MCS NEAR OR S OF CSG ESEWD TO OFF THE SERN GA
   COAST/ SWD INTO WARM SECTOR OVER SWRN GA WHERE AIR MASS REMAINS
   FAVORABLY MOIST AND SURFACE WINDS HAVE MAINTAINED AN ELY COMPONENT.
