AREAS AFFECTED...SRN AL THROUGH S CNTRL GA

CONCERNING...SEVERE THUNDERSTORM WATCH 113...

VALID 311632Z - 311800Z

LIMITED THREAT OF ISOLATED DAMAGING WIND WILL PERSIST NEXT COUPLE
HOURS ALONG SQUALL LINE FROM SRN AL THROUGH S CNTRL GA. HEAVY RAIN
WITH RATES FROM 1 TO 1.5 INCHES PER HOUR WILL ALSO PERSIST...
ESPECIALLY OVER SRN AL ALONG SWRN PORTIONS OF THE LINE. STORMS ARE
BEGINNING TO EXIT SERN PARTS OF WW 113. WW WILL LIKELY BE CANCELLED
WITHIN THE NEXT HOUR OR TWO SINCE THREAT DOES NOT APPEAR HIGH ENOUGH
TO WARRANT ANOTHER WW FARTHER SE. 

A SQUALL LINE EXTENDS FROM SRN AL NEWD THROUGH S CNTRL GA MOVING
SEWD AT 20 TO 25 KT. WIDESPREAD CLOUDS ARE LIMITING THE DEGREE OF
INSTABILITY DOWNSTREAM FROM THE LINE. THE OUTFLOW BOUNDARY IS MOVING
SEWD WITH THE MEAN STEERING FLOW ORIENTED PARALLEL TO THE LINE. THIS
IS RESULTING IN A TENDENCY FOR MANY OF THE CELLS TO BE UNDERCUT BY
THE OUTFLOW OVER SW PORTIONS OF THE LINE. THREAT FOR ISOLATED WIND
DAMAGE MAY BE A LITTLE HIGHER WITH PORTION OF LINE BETWEEN WILCOX
AND LAURENS COUNTIES IN SERN GA WHERE DOWNSTREAM TEMPERATURE- 
DEWPOINT SPREADS ARE LARGER. HOWEVER...INSTABILITY IS ALSO MORE
LIMITED IN THIS REGION. THREAT FOR HEAVY RAIN APPEARS HIGHER OVER
SRN AL ALONG SLOWER MOVING SWRN PARTS OF LINE WHERE STORMS WILL HAVE
THE OPPORTUNITY TO TRAIN LONGER.
