SHORT TERM /TODAY THROUGH MONDAY/...
LOW PRESSURE WHICH HAS PLAGUED THE AREA THE LAST COUPLE OF DAYS
WITH COOL AND RAINY CONDITIONS HAS FINALLY SHIFTED EAST OFF THE
FLORID COAST FOLLOWING THE LEAD OF STACKED UPPER LOW WHICH IS IN A
SIMILAR POSITION. WITH DNVA ON BACK SIDE OF THIS FEATURE AS WELL
AS REDUCED MOISTURE CONVERGENCE AT THE LOW LEVELS...LIGHT RAIN HAS
ABATED WITH RADAR INDICATED ONLY ISOLATED COVERAGE OVER
EASTERN ZONES. ALTHOUGH PRECIP IS GREATLY REDUCED...LOW LEVEL
MOISTURE REMAINS PLENTIFUL FROM LA GRANGE TO ATHENS WITH OVERCAST
LOW CLOUD CONDITIONS TO CONTINUE THROUGH DAYBREAK.

LOW LEVEL CLOUDS WILL CONTINUE TO DECREASE WITH WHAT LITTLE PRECIP
THERE IS COMING TO AN END. SHOULD SEE AT LEAST SOME SUN OVER ALL
LOCATIONS BY THIS AFTERNOON BUT ESPECIALLY ACROSS THE NORTH AND
WILL LEAN TOWARD THE WARMER GUIDANCE FOR HIGH TEMPS.

BUILDING SLIGHTLY OVER THE AREA ALONG WITH PLENTY OF DRY AIR.
SHOULD SEE A NICE TEMPERATURE RECOVERY WITH AFOREMENTIONED RIDGE

FAIRLY STRONG STORMS AS INSTABILITY INDICES INCREASE DURING THE
