LATEST SURFACE ANALYSIS SHOWS A NEARLY STATIONARY COLD FRONT NEAR A  
LA GRANGE TO MILLEDGEVILLE LINE. REGIONAL RADARS SHOW A FEW SMALL  
SHOWERS OCCASIONALLY POPPING UP ALONG AND SOUTH OF THE FRONT... AND  
EXPECT THIS TREND TO CONTINUE THROUGH AT LEAST THE MORNING. THE  
FRONT IS PROGGD TO SAG SOUTH TODAY AS AN UPPER SHORT WAVE CURRENTLY  
OVER NORTH MS TRAVERSES THE STATE AND PROVIDES THE NEEDED PUSH.  
EXPECT THE FRONT TO PUSH SOUTH OF A COLUMBUS TO MACON LINE BY MID TO  
LATE MORNING... THEN SOUTH OF THE FORECAST AREA BY EARLY AFTERNOON.  
LACK OF DEEP LAYER MOISTURE AND INSTABILITY WILL WARRANT SHOWING  
ONLY A SLIGHT CHANCE OF SHOWERS ACROSS PARTS OF CENTRAL GA TODAY FOR  
AREAS ALONG AND SOUTH OF THE FRONT. HIGH PRESSURE AND A COOL/DRY  
NORTHERLY FLOW WILL PREVAIL TONIGHT AND THURSDAY... BRINGING A RAIN  
FREE FORECAST TO THE AREA FOR THE REST OF THE WORK WEEK.  
 
A COOLER AIRMASS WILL BEGIN SPREADING IN OVER THE AREA TODAY BEHIND  
THE SAGGING FRONT... RESULTING IN NEAR NORMAL HIGHS ACROSS NORTH GA  
TODAY... THEN ACROSS BOTH NORTH AND CENTRAL GA BY THURSDAY. LOWS  
TONIGHT WILL BE NEAR OR SLIGHTLY COOLER THAN NORMAL FOR MOST AREAS.  
A MAV AND MET BLEND FOR TEMPS LOOKED REASONABLE THROUGH THE PERIOD.

THE EXTENDED FORECAST STARTS OUT WITH THE DRIER AIRMASS OVER THE

MOVES INTO NORTH GA THE FRONTAL BOUNDARY WEAKENS A BIT WITH THE  
MAJORITY OF THE MOISTURE STAYING NORTH AND EAST OF THE STATE. HAVE
