AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
403 PM EDT SAT AUG 2 2014

.SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...

COOL POOL HAS DEVELOPED INTO AN INSITU CAD WITH A GOOD CHUNK OF
CENTRAL GEORGIA COMPLETELY SOCKED IN. PW VALUES REMAIN
CLIMATOLOGICALLY HIGH IN THE WEDGED AREA...RANGING BETWEEN 1.8 TO 2
INCHES. MACON COULD ACTUALLY BE IN DANGER OF BREAKING OR AT LEAST
TYING THE RECORD LOW HIGH FOR THE DAY /HIGH AS OF AFD TIME: 77...
PREVIOUS RECORD: 79 SET IN 1918/. STILL SEVERAL SHOWERS OUT THERE
ACROSS THE AREA. ALABAMA AND TENNESSEE BROKE OUT OF THE CLOUDS
EARLIER TODAY AND CAPES HAVE INCREASED TO OVER 2000 J/KG IN THOSE
AREAS...AND AS THE CLEARING SPREADS INTO NORTH GEORGIA...COULD SEE
AN INCREASE IN CONVECTION AROUND THE METRO AREA. WILL HAVE TO KEEP
AN EYE ON THAT THROUGH THE EVENING. CANNOT RULE OUT A STRONG STORM
OR TWO BUT OVERALL NOT EXPECTING MUCH.

SYNOPTIC SITUATION CONSISTS OF A STRONG TROUGH IN PLACE OVER
THE EASTERN PORTION OF THE COUNTRY WITH A LOW-LEVEL SHORTWAVE
SHOWING UP BETWEEN 700-850MB ACROSS THE LOWER MISSISSIPPI VALLEY.
THE LONGWAVE TROUGH TRANSLATES EAST THROUGH THE SHORT TERM...PUSHING
THE MOIST SOUTHWEST FLOW FURTHER TOWARDS CENTRAL AND SOUTH GEORGIA.
AS A RESULT...HAVE ONLY SLIGHT CHANCE POPS ACROSS NORTH GEORGIA FOR
SUNDAY. LOOKS LIKE THE SECONDARY SHORTWAVE MOVING IN MAY PROVIDE
ANOTHER WAVE OF PRECIPITATION MOVING NORTH BUT THAT WOULD BE MORE
FOR THE EXTENDED. TEMPERATURES WILL CONTINUE ON THE COOL SIDE OF
NORMAL AND OVERALL NOT TOO BAD FOR EARLY AUGUST.

TDP

.LONG TERM /MONDAY THROUGH SATURDAY/...

LONG TERM PATTERN REMAINS CONSISTENT. SOME DRYING ACROSS THE NORTH
INDICATED FOR MONDAY INTO TUESDAY BEHIND A WEAK SURFACE BOUNDARY.
NOT CONFIDENT HOW FAR SOUTH THE BOUNDARY WILL GET...BUT SOME LOWER
POPS INDICATED MAINLY FOR THE NORTH MONDAY INTO TUESDAY NIGHT.
OTHERWISE CHANCE OR SLIGHT CHANCE IN A MAINLY DIURNAL PATTERN AS
THE UPPER FLOW BECOMES MORE WEST TO NORTHWEST. A STRONG SHORT WAVE
SHOWN MOVING THROUGH THE OHIO VALLEY TOWARD THE END OF THE WEEK.
BUT FOR NOW...CHANCE POPS OKAY ACROSS THE NORTH. PREVIOUS
DISCUSSION IS INCLUDED BELOW.

.PREVIOUS...
LONG TERM /407 AM EDT SAT AUG 2 2014/...

THE YEAR OF THE SUMMER COLD FRONT CONTINUES FOR AT LEAST THE FIRST
PART OF THE LONG TERM AS PERSISTENT EAST COAST LONGWAVE TROUGH
ALLOWS FOR A WEAK FRONT TO PUSH INTO NORTH GEORGIA. THIS WILL BE
MAINLY MARKED BY A DECREASE IN MOISTURE AS HAS BEEN THE CASE WITH
SEVERAL FRONTS ALREADY THE PAST FEW WEEKS. DEEP LAYER MOISTURE
WILL DROP FOR NORTH GEORGIA AS WELL ON MONDAY WITH ONLY SLIGHT
CHANCE POPS REQUIRED AND THIS TOO MAY PROVE TO BE TOO MUCH GIVEN
MEAGER FORCING AND MOISTURE PROFILE. TO THE SOUTH...A MUCH
DIFFERENT STORY AS AFOREMENTIONED TROUGH AND EMBEDDED SHORTWAVES
CONTINUES LIKELY POPS IN AREAS OF ADEQUATE MOISTURE WHICH LOOKS TO
BE FROM COLUMBUS TO MACON AND POINTS SOUTHWARD FOR MONDAY.

MAIN CHANGE IN THE EXTENDED WILL BE THE EXODUS OF THE UPPER TROUGH
EVENTUALLY BY MID WEEK OFF THE EAST COAST AND THE LOCAL AREA
REPLACED BY BERMUDA RIDGE AXIS UP TO 700MB AND A NON DISTINCT
PATTERN FROM 500MB ON UP. THIS ALONG WITH MOISTURE RETURNING TO
NEAR NORMAL LEVELS SCREAMS FOR OUR TYPICAL LOW END SCATTERED
THUNDERSTORM ACTIVITY AND WILL ADVERTISE SUCH IN NEW EXTENDED.

DEESE

AVIATION...
18Z UPDATE...
STILL WIDESPREAD MVFR CIGS AROUND THIS AFTERNOON THOUGH METRO TAFS
BEGINNING TO SEE SOME IMPROVEMENT. CONTINUED TREND OF VCSH
EVERYWHERE...AND THOUGH CANNOT RULE OUT ISOLATED TSRA...NOT ENOUGH
CONFIDENCE TO INCLUDE IN TAFS AT THIS TIME. BEST MOISTURE MOVES SE
OVERNIGHT SO AT THIS TIME DO NOT EXPECT A CIG AT THE NORTHERN TAFS
OVERNIGHT OR SUNDAY MORNING BUT CANNOT COMPLETELY RULE OUT THE
POSSIBILITY. MCN AND CSG SHOULD SEE CIGS. POTENTIAL FOR CONVECTION
EXISTS AGAIN TOMORROW BUT AGAIN NOT ENOUGH CONFIDENCE TO INCLUDE
PROB30 YET. WINDS E THROUGH THE PERIOD GENERALLY AROUND 5KT.

//ATL CONFIDENCE...18Z UPDATE...
LOW ON NO CIGS OVERNIGHT/SUNDAY MORNING.
MEDIUM ON TSRA DEVELOPMENT...LOW ON ANY IMPACTS TO ATL.
HIGH ON ALL OTHER ELEMENTS.
