UPDATE
 
 
EVENING UPDATE.  
 

 
   
DISCUSSION
 
 
STORMS HAVE ENDED ACROSS THE CWA LATE THIS EVENING AND BELIEVE  
THAT MOST AREAS WILL REMAIN DRY FOR MUCH, IF NOT ALL, OF THE  
OVERNIGHT HOURS. TOUCHED UP HOURLY RAIN CHANCES THROUGH DAYBREAK  
TO ACCOUNT FOR CURRENT TRENDS IN RADAR IMAGERY AS WELL AS CAM  
GUIDANCE. STILL THINK SOME PATCHY FOG WILL BE POSSIBLE TONIGHT  
BUT NOT CONFIDENT ON EXACTLY HOW WIDESPREAD IT WILL BE. CONVECTIVE  
DEBRIS CLOUDS SHOULD CONTINUE TO DISSIPATE OVER THE NEXT FEW  
HOURS, LEAVING EITHER SOME SCATTERED TO BROKEN CIRRUS CLOUDS OR  
PERHAPS EVEN SOME MOSTLY CLEAR SKIES AT TIMES. THIS SHOULD FAVOR  
MAINLY THE NORTHERN PARTS OF THE CWA AS THE REMNANTS OF SOME  
SHOWERS MOVING NORTH THROUGH GEORGIA RIGHT NOW MAY ADD TO THE  
CLOUDINESS IN THE SOUTH AND THUS HAMPER FOG DEVELOPMENT.  
OTHERWISE, NOT A LOT OF CHANGE FOR THE UPDATE.

00Z TAF DISCUSSION.  
 
WHILE GREATER COVERAGE OF STORMS IS EXPECTED TOMORROW AFTERNOON,  
LACK OF A FRONT OR OTHER FOCUS FOR DEVELOPMENT SHOULD STILL KEEP  
IT ON THE SCATTERED SIDE SO WILL JUST CARRY VCSH AND PROB30 GROUPS  
FOR TOMORROW AFTERNOON AT ALL TERMINALS. OTHERWISE, WILL PLAY A  
PERSISTENCE FORECAST FOR THE OVERNIGHT/EARLY MORNING HOURS WITH  
SOME SCT-BKN MVFR CIGS AT KCHA AND KTYS. AT KTRI I BELIEVE THERE  
WILL BE A MIX OF LOW CLOUDS AND FOG SO I'M NOT CONFIDENT IN  
EXACTLY WHICH ONE WINS OUT. THEY DID GET SOME RAIN THIS AFTERNOON  
SO IF IT'S FOG THAT WINS OUT, SOME 1/2SM TO 1/4SM VSBY ISN'T OUT  
OF THE QUESTION FOR SURE.
