...UPDATED TO INCLUDE AVIATION DISCUSSION...
   
MAIN DIFFERENCES IN THE MODELS IS TIMING. LOOKING AT THE FWC/MET/MAV 
NUMBERS...ALL DO AGREE THAT THERE IS A DECENT CHANCE OF RAIN LATE 
SUNDAY AND SUNDAY NIGHT ACROSS NORTH GEORGIA WITH A LESSER CHANCE 
ACROSS CENTRAL GEORGIA. WENT MORE WITH THE AVN TIMING. BROUGHT A 
BAND OF MOISTURE INTO NORTH GEORGIA LATE TONIGHT...THEN THE AREA 
BECOMES PARTLY TO MOSTLY CLOUDY DURING THE DAY SUNDAY WITH ANOTHER 
SURGE OF MOISTURE AFFECTING THE NORTH PART OF THE STATE LATE SUNDAY 
AFTERNOON...BUT MAINLY AFTER SUNSET SUNDAY IN ASSOCIATION WITH THE 
COLD FRONT. AS THE SYSTEM MOVES EAST IT WEAKENS AND EXPECT THE 
CHANCES OF RAIN TO DROP OFF THE FURTHER SOUTH THE COLD FRONT MOVES. 
SCATTERED SHOWERS HANG AROUND MONDAY ACROSS CENTRAL GEORGIA THEN THE 
DRIER AIR MOVES IN CLEARING OUT THE SKIES.

AVIATION DISCUSSION...
VFR CONDITIONS SHOULD PREVAIL THROUGH 12Z SUN. EXPECT SCT-BKN CIRRUS 
THROUGHOUT THE DAY...GENERALLY THICKENING AS THE DAY WEARS ON WITH 
UPPER LOW IN TX SHEARING OUT AS IT MOVES ENE THROUGH SUN. LOW-LEVELS 
AT TAF SITES WILL REMAIN DRY THROUGH 12Z SUN. RADIATIONAL COOLING 
THIS MORNING WILL ALLOW FOR ISOLATED SPOTS OF 5-6SM BR. SURFACE HIGH 
CENTERED OVER NE GA/SC VICINITY WILL SHIFT SLOWLY EAST. WIND 
DIRECTION BIGGEST FORECAST PROBLEM OF THE DAY...ESPECIALLY FOR ATL. 
INDICATED VRB03KT MOST LOCATIONS...BUT TENDENCY WILL BE 130-150 
THROUGH MID-AFTERNOON...THEN BECOMING MORE 160-190...SPEEDS 
GENERALLY LESS THAN 6KT.
