AREAS AFFECTED...NRN AND ERN AL/W CENTRAL GA

CONCERNING...SEVERE THUNDERSTORM WATCH 208...

VALID 191931Z - 192100Z

THUNDERSTORMS CONTINUE TO DEVELOP WWD ACROSS GA INTO AL.  NEW WW
WILL LIKELY BE REQUIRED...TO REPLACE WW 208 WHICH IS SCHEDULED TO
EXPIRE AT 20/21Z.

LATEST RADAR IMAGERY CONTINUES TO SHOW SLIGHTLY-ELEVATED
THUNDERSTORMS -- NOW SHOWING SUPERCELL CHARACTERISTICS -- DEVELOPING
WWD ACROSS NWRN AL JUST TO THE COOL SIDE OF WSWWD-MOVING OUTFLOW
BOUNDARY.  ADDITIONALLY... A NEW STORM HAS DEVELOPED OVER SRN MORGAN
COUNTY AL...NEAR THE INTERSECTION OF THE NW-SE OUTFLOW BOUNDARY AND
NW-SW PRE-FRONTAL TROUGH.  

WITH WEAK SHORT-WAVE RIDGING ACROSS THIS AREA...IT APPEARS THAT
STORM DEVELOPMENT WILL REMAIN LIMITED TO ZONES OF LOW-LEVEL FORCING
INVOF SURFACE BOUNDARIES.  THUS...EXPECT SUBSEQUENT DEVELOPMENT OF
STORMS TO REMAIN TIED TO THE OUTFLOW...AND INVOF THE OUTFLOW/SURFACE
TROUGH INTERSECTION.

GIVEN STRONG INSTABILITY AND FAVORABLE SHEAR...CONTINUED THREAT FOR
SEVERE/SUPERCELL STORMS SHOULD PERSIST INTO THE EVENING...WELL
BEYOND THE 21Z EXPIRATION OF WW 208.  THEREFORE...NEW WW WILL LIKELY
BE ISSUED SHORTLY...ADDRESSING THE ONGOING THREAT FOR HAIL AND THE
POTENTIAL FOR LOCALLY DAMAGING WINDS AND/OR A COUPLE TORNADOES.
