   AREAS AFFECTED...CNTRL AL THROUGH CNTRL AND N CNTRL GA
   
   CONCERNING...TORNADO WATCH 164...165...
   
   VALID 042017Z - 042145Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 164...165...CONTINUES.
   
   THREAT FOR LOCALLY DAMAGING WIND...ISOLATED LARGE HAIL AND ISOLATED
   TORNADOES WILL PERSIST NEXT FEW HOURS FROM MUCH OF CNTR AL THROUGH
   CNTRL AND N CNTRL GA. 
   
   THIS AFTERNOON A CONVECTIVE OUTFLOW BOUNDARY EXTENDS FROM NRN AL
   SWWD THROUGH SRN MS...CNTRL LA INTO SERN TX. THUNDERSTORMS REMAIN
   ACTIVE ALONG PORTIONS OF THIS BOUNDARY INCLUDING W CNTRL THROUGH NRN
   AL. THE WARM SECTOR HAS DESTABILIZED EAST OF OUTFLOW BOUNDARY AND
   SOUTH OF RETREATING WEDGE FRONT THAT NOW EXTENDS FROM ERN NC SWWD
   THROUGH WRN SC THEN NWWD THROUGH NERN GA. NUMEROUS DISCRETE STORMS
   HAVE DEVELOPED IN WARM SECTOR FROM S CNTRL AL NEWD THROUGH W CNTRL
   GA. LOW LEVEL WIND HAVE VEERED TO SSWLY...REDUCING THE SIZE OF THE
   0-1 KM HODOGRAPHS SOMEWHAT. HOWEVER...EFFECTIVE BULK SHEAR OF 40-50
   KT REMAINS VERY FAVORABLE FOR UPDRAFT ROTATION AND SPLITTING
   SUPERCELLS. DAMAGING WIND REMAINS THE PRIMARY THREAT WITH THE LINE
   OF STORMS AS IT ADVANCES EWD. HAIL AND ISOLATED TORNADOES REMAIN
   POSSIBLE WITH THE DISCRETE SUPERCELLS DEVELOPING AHEAD OF THE LINE.
   TORNADO POTENTIAL COULD BE LOCALLY ENHANCED IN NARROW CORRIDOR OVER
   NRN GA AS STORMS CROSS THE MODIFYING WEDGE FRONT BEFORE THEY BECOME
   ELEVATED AS THEY MOVE FARTHER INTO THE COOL SIDE OF THIS BOUNDARY.
