   AREAS AFFECTED...SERN MS THROUGH SRN AL
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 490...
   
   VALID 171945Z - 172045Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 490
   CONTINUES.
   
   THREAT FOR ISOLATED DAMAGING WIND AND SOME HAIL WILL PERSIST NEXT
   COUPLE HOURS ACROSS SRN AL INTO WRN GA. IT STILL APPEARS THAT A FEW
   STORMS MAY ALSO DEVELOP FARTHER WEST INTO SERN MS.
   
   LINE OF STORMS FROM W-CNTRL GA INTO S-CNTRL AL CONTINUES SEWD AND IS
   IN PROCESS OF MERGING WITH SCATTERED ACTIVITY THAT DEVELOPED IN WARM
   SECTOR AND ALONG SEA BREEZE BOUNDARIES. THESE CELL MERGERS WILL
   RESULT IN BRIEF INTENSIFICATION OF STORMS WITH AUGMENTED DOWNBURST
   POTENTIAL UNTIL THE WARM SECTOR IS OVERTURNED. SATELLITE DATA SHOW
   CUMULUS INCREASING FARTHER WEST ALONG OUTFLOW BOUNDARY INTO SWRN AL
   AND SERN MS WHERE CONVECTIVE INHIBITION CONTINUES TO WEAKEN AS
   TEMPERATURES CLIMB INTO THE MID 90S. ANY STORMS THAT DEVELOP IN THIS
   AREA WILL ALSO BECOME CAPABLE OF PRODUCING ISOLATED DOWNBURST WINDS
   AND HAIL GIVEN THE FAVORABLE THERMODYNAMIC ENVIRONMENT.
