AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSONVILLE FL 230 PM EDT SAT JUL 12 2008 .PUBLIC...STACKED LOW REMAINS CENTERED OFF THE CAROLINA COASTLINE WITH MEAN TROUGH AXIS EXTENDING SOUTHWEST ACROSS NORTHEAST FLORIDA. DOPPLER RADAR INDICATES GREATEST COVERAGE OF SHOWERS AND THUNDERSTORMS DEVELOPING ALONG AND PRECEDING THIS FEATURE... ALTHOUGH THERE REMAINS ENOUGH MOISTURE AND DYNAMICAL LIFT ASSOCIATED WITH BROAD CIRCULATION TO GENERATE ISOLATED SHOWERS OVER SOUTH GEORGIA. LITTLE CHANGE IS EXPECTED THROUGH THIS EVENING AS AFOREMENTIONED LOW MEANDERS OFFSHORE WITH TROUGH AXIS ADVANCING SOUTHWARD OVER THE FLORIDA PENINSULA. HAVE RESERVED POPS TONIGHT FOR NORTHEAST FLORIDA AND PORTIONS OF SOUTHEAST GEORGIA SOUTH OF U.S. HIGHWAY 82. STACKED LOW WILL APPROACH THE FLORIDA ATLANTIC WATERS ON SUNDAY WITH UPSTREAM RIDGE BUILDING INTO THE SOUTHEAST REGION. DYNAMICS AND MOISTURE LOOK RATHER UNIMPRESSIVE FOR SUNDAY EXCEPT FOR OUR SOUTHERN-MOST ZONES WHERE SEA-BREEZES WILL LIKELY COLLIDE...THUS WILL RESERVE SLIGHT CHANCE POPS FOR MOST OF JAX CWA.
