MESOSCALE DISCUSSION 1579
NWS STORM PREDICTION CENTER NORMAN OK
1143 AM CDT TUE AUG 19 2014

AREAS AFFECTED...PARTS OF SOUTHERN AL/GA TO ADJACENT SRN SC

CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY

VALID 191643Z - 191915Z

PROBABILITY OF WATCH ISSUANCE...5 PERCENT

SUMMARY...LOCALLY STRONG WIND GUSTS WILL BE POSSIBLE THROUGH THE
AFTERNOON AS STORMS CONTINUE TO DEVELOP AND GENERALLY MOVE EWD
ACROSS SOUTH-CENTRAL AND SOUTHEAST AL THROUGH SOUTHERN GA TO PART OF
FAR SOUTHERN SC.  THE LACK FOR GREATER STORM ORGANIZATION POTENTIAL
PRECLUDES THE NEED FOR A SEVERE TSTM WATCH AT THIS TIME.

DISCUSSION...TIME-LAPSE OF VISIBLE SATELLITE IMAGERY AND SURFACE
ANALYSES INDICATED A BOUNDARY EXTENDING FROM CENTRAL SC SWWD INTO
SERN GA AND THEN WWD INTO SERN AL.  RADAR IMAGERY INDICATED TSTMS
HAD DEVELOPED ALONG THIS BOUNDARY OVER PARTS OF SRN GA AND SRN
AL...WITHIN A MOISTURE-RICH ENVIRONMENT /PW UP TO 2 INCHES AND
SURFACE DEW POINTS IN THE LOWER-MID 70S/ THAT HAS ALREADY BECOME
STRONGLY UNSTABLE /MLCAPE 2000-3000 J PER KG/.  ALTHOUGH EFFECTIVE
BULK SHEAR IS RATHER WEAK...30 KT WLY MIDLEVEL FLOW WILL SUPPORT EWD
MOVEMENT/PROPAGATION OF STORMS THROUGH THE AFTERNOON.  THIS COMBINED
WITH ANY COLD-POOL ENHANCEMENT...AS CURRENTLY OBSERVED IN SERN
GA...SHOULD SUPPORT A LOCALLY STRONG WIND GUST POTENTIAL.
