AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
201 AM EST FRI NOV 28 2014

.SHORT TERM /TODAY THROUGH SATURDAY/...
WEAK UPPER WAVE IN THE FLOW MOVING ACROSS THE MIDWEST WILL TRAVERSE
THE TN VALLEY THIS MORNING. ALTHOUGH THE MAIN IMPACTS WITH THIS WILL
BE FURTHER NORTH THAN THE CWA...THIS MAY HELP TO KEEP THE CLOUD
COVERAGE ACROSS FAR NORTH GEORGIA THROUGH SUNRISE. HIGH PRESSURE AT
THE SFC MOVES ACROSS THE STATE TODAY AND WILL RESULT IN WEAK WINDS
BY THE AFTERNOON ACROSS THE CWA. ALTHOUGH THE RIDGE SLIDES OFF THE
CAROLINA COAST BY SATURDAY...IT STILL DOMINATES THROUGH THE SHORT
TERM. WITH HIGH PRESSURE AT THE SFC AND THE UPPER LEVEL FLOW
FLATTENING OUT BY SATURDAY...SHORT TERM FORECAST LOOKS DRY.

HIGH TEMPERATURES TODAY WILL BE AROUND 10 DEGREES COOLER THAN
AVERAGE...BUT AS THE NW FLOW ALOFT FLATTENS OUT FOR SATURDAY AND THE
SFC FLOW BECOMES SOUTHERLY...HIGH TEMPERATURES WILL WARM FOR
SATURDAY AND BE ONLY A FEW DEGREES BELOW NORMAL.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
GFS/ECMWF IN GOOD AGREEMENT THROUGH THIS WEEKEND WITH DRY CONDITIONS
AND A SLOW WARMING TREND. DIFFERENCE DEVELOP WITH THE NEXT SHORT
WAVE FOR EARLY NEXT WEEK. THE GFS HAS MORE MOISTURE WHILE THE ECMWF
IS MAINTAINING A DRIER SOLUTION. GIVEN THAT MOISTURE IS LACKING...AM
TRENDING WITH THE LESS AGGRESSIVE ECMWF AND KEEPING SLIGHT CHANCE TO
CHANCE POPS FOR EXTREME NORTH GA MONDAY NIGHT THROUGH TUESDAY NIGHT.
THE NEXT SYSTEM FOR THE END OF NEXT WEEK ALSO HAS DIFFERENCES. THE
GFS IS MUCH MORE AGGRESSIVE WITH MOISTURE WHILE THE ECMWF IS MUCH
SLOWER WITH THE SYSTEM KEEPING THE MOISTURE WELL TO THE WEST. WILL
GO WITH SLIGHT CHANCE POPS FOR NORTH GA TOWARD THE END OF NEXT WEEK.
NO MAJOR TEMPERATURE SWINGS AS THE SHORT WAVES ARE MOVING THROUGH A
WEST TO SOUTHWEST FLOW KEEPING THE COLD CANADIAN AIR WELL TO THE
NORTH OF GA.

360 AND COULD SEE A COUPLE NNE OBSERVATIONS BUT FOR THE MOST PART
EXPECT WINDS ON THE NW SIDE AND BY THE MID AFTERNOON WILL BE
TRANSITIONING TO W AND THEN SW BY TONIGHT.

//ATL CONFIDENCE...06Z UPDATE...
HIGH CONFIDENCE ON CIGS AND VSBYS. MEDIUM CONFIDENCE ON WIND DUE
TO POTENTIAL OF A FEW NNE OBS MID MORNING.
