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.
