AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
719 AM EDT TUE JUL 29 2014

.SHORT TERM /TODAY THROUGH WEDNESDAY/...
/ISSUED AT 425 AM EDT TUE JUL 29 2014/
AN UNSEASONABLY COOL/DRY PATTERN WILL PREVAIL AS A BROAD AREA OF LOW
PRESSURE OVER EASTERN CANADA AND HIGH PRESSURE OVER THE SOUTHERN
PLAINS MAINTAIN A COOL/DRY NORTHWEST FLOW OVER THE STATE THROUGH THE
SHORT TERM. THIS WILL RESULT IN A RAIN FREE FORECAST WITH THE MAIN
STORY BEING THE MUCH ANTICIPATED 5 TO 10 DEGREE COOLER TEMPERATURES
EXPECTED ACROSS THE AREA FOR THE NEXT FEW DAYS.

DESPITE AMPLE SUNSHINE... THE COOLER AIR MASS SPREADING DOWN FROM
THE NORTH WILL HOLD DAYTIME TEMPERATURES IN THE MID 70S TO MID 80S
FOR MOST OF NORTH GA... AND MID 80S TO LOWER 90S ACROSS CENTRAL GA
FOR THE NEXT COUPLE OF DAYS. THE COOLER AIR MASS WILL REALLY BE FELT
TONIGHT... AS TEMPERATURES DIP INTO THE 50S AND 60S AND THREATEN
RECORD LOWS FOR ALL FOUR OFFICIAL CLIMATE SITES TONIGHT. ALTHOUGH
SLIGHTLY WARMER... THE COOL LOW TEMPERATURES WILL PERSIST AGAIN
WEDNESDAY NIGHT... WITH LOWS IN THE LOWER TO MID 60S FOR MOST AREAS.
ENJOY! AUGUST IS JUST AROUND THE CORNER.

WEAK SURFACE HIGH PRESSURE OVER THE AREA TO START THE EXTENDED
FORECAST. AN UPPER LEVEL DEEP LONG WAVE TROUGH ALSO MOVES IN OVER
THE REGION IN THE SHORT TERM AND SETTLES IN THROUGH THE END OF THE
WEEK. THIS TROUGH PULLS IN SOME DRIER AIR AND LOWER DEW POINTS AND

AGAIN ACROSS WESTERN AND SOUTHERN PORTION OF OUR CWA WITH
A FEW WAVES MOVING ACROSS THE AREA AND A FRONTAL SYSTEM MOVING IN BY
