VALID 080421Z - 080545Z

THREAT FOR ISOLATED DAMAGING WIND WILL CONTINUE MAINLY WITH LINE OF
STORMS MOVING THROUGH CNTRL GA NEXT COUPLE HOURS. 

LINE OF STORMS JUST W OF MACON CONTINUES EAST AT 50 KT. DESPITE SOME
INCREASE IN LOW LEVEL MOISTURE DUE TO THE STRENGTHENING SWLY LOW
LEVEL JET...THE LINE IS MOVING EWD FASTER THAN THE ATMOSPHERE CAN
DESTABILIZE...AND NOCTURNAL COOLING IS OFFSETTING THE EFFECT OF THE
INCREASE IN LOW LEVEL MOISTURE SOMEWHAT. THE ATMOSPHERE IS ONLY
MARGINALLY UNSTABLE WITH MUCAPE AOB 300 J/KG AND INSTABILITY WILL
BECOME INCREASINGLY MARGINAL AS THE LINE CONTINUES EAST. AS A
RESULT...TRENDS HAVE BEEN FOR THE LINE TO WEAKEN AND LIGHTNING
ACTIVITY TO DIMINISH. HOWEVER...THE LINE REMAINS EMBEDDED WITHIN
VERY STRONG LOW-MID LEVEL WIND/SHEAR PROFILES AND LIFT ALONG THE
GUST FRONT WILL HELP MAINTAIN A LOW TOPPED...FORCED LINE CAPABLE OF
PRODUCING ISOLATED STRONG-DAMAGING WIND GUSTS NEXT COUPLE HOURS.
