NATIONAL WEATHER SERVICE PEACHTREE CITY GA
724 AM EDT WED SEP 17 2014

.SHORT TERM /TODAY THROUGH THURSDAY/...
/ISSUED AT 411 AM EDT WED SEP 17 2014/
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.

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
/ISSUED AT 411 AM EDT WED SEP 17 2014/
THE EXTENDED FORECAST STARTS OUT WITH THE DRIER AIRMASS OVER THE
REGION AND NO PRECIPITATION. HIGH PRESSURE RIDGE OVER THE STATE
WILL KEEP GEORGIA DRY THROUGH AT LEAST SATURDAY/SUNDAY MORNING BEFORE
ANOTHER FRONTAL SYSTEM MOVES INTO NORTH GA MONDAY. BOTH THE GFS
AND ECMWF AGREE WITH THE DRIER AIR MASS AND HIGH PRESSURE RIDGE
STAYING OVER THE AREA THROUGH THE WEEKEND. AS THE NEXT FRONTAL SYSTEM
MOVES INTO NORTH GA THE FRONTAL BOUNDARY WEAKENS A BIT WITH THE
MAJORITY OF THE MOISTURE STAYING NORTH AND EAST OF THE STATE. HAVE
DECIDED TO ONLY GO WITH A SLIGHT CHANCE OF SHOWERS AND THUNDERSTORMS
ACROSS NORTH GA SUNDAY AFTERNOON AND SPREADING THE PRECIP SOUTHWARD
MONDAY/TUESDAY. MODELS ALSO CONTINUE TO INDICATE COOLER TEMPS IN
STORE FOR THE STATE...ESPECIALLY WITH THE COOLER DRIER AIR MASS
MOVING IN. LOOKING AT HIGH TEMPS IN THE 70S AND 80S THROUGH THE
BEGINNING OF NEXT WEEK.

MVFR LEVEL SCT CLOUDS MAY PUSH ACROSS ATL THIS MORNING WITH THE
DISTURBANCE... THEN EXPECT MAINLY MID LEVEL SCT CLOUDS DURING
