AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
920 PM EDT WED OCT 15 2008
.UPDATE...
NO CHANGES PLANNED. SURFACE HIGH AND RIDGE ALOFT PROVIDING TRANQUIL
WEATHER WEDNESDAY EVENING. IN GENERAL...THICKNESSES SUGGEST
OVERNIGHT MIN TEMPERATURES WILL BE CLOSE TO THOSE OBSERVED LAST
NIGHT. IF THERE ARE ANY DIFFERENCES... WE MIGHT SEE MINS A DEGREE OR
TWO HIGHER ACROSS NORTH GEORGIA WHERE HIGH LEVEL MOISTURE SHOULD
BEGIN ARRIVING LATER TONIGHT...AND MAYBE A DEGREE OR TWO LOWER
ACROSS CENTRAL GEORGIA WHERE THERE SHOULD BE NOTHING TO INTERFERE
WITH RADIATIONAL COOLING.
&&
.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
THE VERTICALLY STACKED HIGH REMAINS CENTERED OVER GEORGIA THIS
AFTERNOON. ALL MODELS BEGIN WEAKENING AND FORCING THE CENTER OF
THE HIGH TO THE SOUTH AS A SHORTWAVE MOVES ACROSS THE OHIO
VALLEY THURSDAY...WHICH WILL PUSH A COLD FRONT INTO THE AREA
THURSDAY NIGHT. MODELS ARE IN GOOD AGREEMENT WITH TIMING OF THE
FRONT...ALTHOUGH NAM IS SLOWER THAN THE REST SO STAYED CLOSE TO
GFS AND CONSENSUS FOR MOVING FRONT ACROSS THE AREA. THANKS TO
CURRENT RIDGE...TEMPERATURES ALOFT WILL BE VERY WARM THURSDAY AND
FRIDAY...WHICH WILL SEVERELY LIMIT INSTABILITY AHEAD OF THE FRONT.
WILL LEAVE MENTION OF THUNDER IN FORECAST FOR FRIDAY AFTERNOON AS
UPPER TROUGH AMPLIFIES RESULTING IN MORE FORCING...SO CAN`T RULE
OUT AN ISOLATED RUMBLE OF THUNDER OR TWO. BASICALLY EXPECT A
NARROW BAND OF SHOWERS ALONG THE FRONT...WITH MOST AREAS SEEING
LESS THAN A TENTH OF AN INCH OF RAIN. NOT EXPECTING ANY SEVERE
WEATHER AT THIS TIME.
EXPECT NEAR RECORD HIGHS ACROSS MIDDLE GEORGIA AGAIN ON THURSDAY.
OVER THE NORTH...APPROACHING COLD FRONT WILL LEAD TO INCREASED
CLOUD COVER THURSDAY AFTERNOON...WHICH WILL HOLD TEMPERATURES DOWN
IN THE 70S NORTH OF AN ATLANTA TO GAINESVILLE LINE. STAYED CLOSE
TO PERSISTENCE FOR LOWS TOMORROW MORNING... WHICH TENDED TO BE A
COUPLE OF DEGREES WARMER THAN MAV AND MET AT MOST LOCATIONS.
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
FRONT AND SHORTWAVE WILL MOVE OUT OF THE AREA FRIDAY NIGHT...
LEAVING COLD AND DRY ADVECTION IN ITS WAKE. WILL SEE TEMPERATURES
RETURN TO FALL LEVELS OVER THE WEEKEND...AND REMAIN DURING THE
WEEK...AS COOL HIGH PRESSURE REMAINS ENTRENCHED ACROSS THE EAST
AND SOUTHEAST. ALTHOUGH THE WESTERLIES WILL BE ACTIVE DURING THE
EXTENDED PERIOD...THIS ACTIVITY WILL STAY WELL NORTH OF GEORGIA SO
WE WILL REMAIN DRY.
&&
.AVIATION...

FRONT SLIDING INTO NORTHWEST GA THURSDAY AFTERNOON...BUT VFR
CONDITIONS PERSISTING THROUGH THE DAY. ONLY SCATTERED CLOUDS 4 TO
