AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
236 AM EST FRI DEC 25 2009
.SHORT TERM /TODAY THROUGH SUNDAY/...
LATEST SURFACE ANALYSIS SHOWS THE SURFACE LOW OVER NORTH MO AND TRAILING
COLD FRONT PUSHING INTO FAR WESTERN AL. THE ASSOCIATED WARM FRONT IS
NOSING UP NEAR A LGC TO MCN TO DBN LINE...WITH UPPER 50 TO LOWER 60
DEWPOINTS SOUTH OF THE FRONT GRADUALLY SPREADING NORTHWARD. LOOKS LIKE
THE HIGH TEMPERATURES HAVE ALREADY...OR WILL OCCUR THIS MORNING. WILL
HAVE TO GO WARMER THAN GUIDANCE SUGGESTS FOR MOST AREAS ACROSS THE
SOUTHERN ZONES WHERE HIGHS ARE OCCURRING NOW. MAIN CONCERN IS THE
GRADIENT WIND...THAT HAS BEEN KNOCKING NUMEROUS TREES DOWN ACROSS
MAINLY NORTH GA THIS MORNING. EXPECT THE GRADIENT TO BEGIN RELAXING
A BIT AS THE SURFACE TROUGH MOVES INTO GA. HOWEVER...BEHIND THE
COLD FRONT... THE GRADIENT TIGHTENS AGAIN AS A COLD DOME OF HIGH
PRESSURE BUILDS FROM THE WEST. AT THIS TIME... PLAN TO LET THE HIGH
WIND WARNING AND WIND ADVISORY FOR NORTH AND CENTRAL GA RESPECTIVELY
RIDE THROUGH 7 AM THIS MORNING...THEN REISSUE A WIND ADVISORY FOR
THE AREA THROUGH THE AFTERNOON. THE FAR SOUTHERN ZONES MAY BE ABLE
TO STAY OUT OF THE LATER ADVISORY...BUT WILL FINE TUNE THIS JUST
BEFORE 7 AM. HAVE NOT SEEN MUCH LIGHTNING MAKE IT INTO CENTRAL GA
SO FAR THIS MORNING...AND SUSPECT THIS TREND WILL CONTINUE AS THE
SURFACE LOW AND UPPER SUPPORT LIFT FURTHER NORTH. HOWEVER... AS
THE COLD FRONT SWEEPS ACROSS THIS MORNING...THE WARM...INCREASINGLY
UNSTABLE AIR MASS NOSING IN OVER THE SE ZONES WILL WARRANT THE MENTION
OF ISOLATED THUNDER THROUGH THE MORNING. A DRIER AND MUCH COOLER
AIR MASS WILL SPREAD IN OVER THE AREA THIS AFTERNOON AND OVERNIGHT...
WITH GUSTY WINDS MAKING THINGS FEEL MUCH COLDER. MET AND MAV GUIDANCE
WERE CLOSE FOR LOWS TONIGHT...SO WILL NOT STRAY FAR. TOOK A MAV
AND MET BLEND FOR SUNDAY WITH SOME UNCERTAINTY OF CLOUDS AND
POSSIBLY A SLIGHT CHANCE OF RAIN TRYING TO DEVELOP COURTESY OF AN
UPPER DISTURBANCE THAT TRACKS ACROSS THE SOUTH ON SUNDAY.
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
BOTH GFS AND ECMWF SHOW ANOTHER GULF LOW DEVELOPING WEDNESDAY
NIGHT...THEN TRACKING ACROSS NORTH OR CENTRAL FL ON THURSDAY. THIS
WOULD BE SPREAD CLOUDS AND RAIN CHANCES OVER MUCH OF THE AREA ON
THURSDAY. IT APPEARS THIS WILL BE AN OVERRUNNING EVENT WITH A COLD
STABLE RAIN ON TAP. THEREFORE...WILL SHOW NO MENTION OF THUNDER
AT THIS TIME.
