AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
906 PM EST MON NOV 5 2007

.UPDATE...
AN APPROACHING COLD FRONT WAS ALONG AS OF 01Z WAS ALONG A
NASHVILLE TO MEMPHIS LINE...HEADED SOUTHEAST TOWARD GEORGIA.
RUC/NAM/GFS MODEL GUIDANCE ALL POINTING AT LOW LEVEL WINDS
INCREASING TO AROUND 40 KNOTS ESPECIALLY IN THE 850-900 MB LAYER
AHEAD OF THE BOUNDARY. 00Z FFC SOUNDING SHOWS JUST HOW DRY THE
PRE-FRONTAL AIRMASS IS...SUGGESTING THAT EVAPORATIVE COOLING
COINCIDENT WITH SHOWERS APPROACHING FROM TENNESSEE SHOULD BE
FAIRLY EFFICIENT AT TRANSFERRING THAT MOMENT TO THE SURFACE IN
OUR MOUNTAIN LOCATIONS. SURFACE LAYER SHOULD COOL ENOUGH BELOW
2KFT TO PREVENT MUCH GUSTINESS FROM REACHING THE GROUND ACROSS
MOST OF THE FORECAST AREA. HOWEVER...LOCATIONS ABOVE 2500-3000
FEET SHOULD SEE PRETTY STRONG GUSTS AROUND 40 MPH LATE TONIGHT.
THOSE STRONG GUSTS WILL BE RELATIVELY SHORT-LIVED...SUBSIDING AS
THE COLD FRONT NEARS TOWARD DAYBREAK. GUSTS SHOULD PICK BACK UP
AGAIN IN COLD ADVECTION BEHIND THE FRONT TUESDAY MORNING...BUT
EXPECT SPEEDS TO BE BELOW ADVISORY RANGE BY THAT POINT.

THE ONLY OTHER SIGNIFICANT WEATHER FEATURE REMAINS THE COLD AIR
ARRIVING BEHIND THE COLD FRONT. LATEST INDICATIONS ARE THAT
TEMPERATURES WILL DIP BELOW FREEZING IN MANY LOCATIONS TUESDAY
NIGHT...PERHAPS NORTH OF A LA GRANGE TO GRIFFIN TO WASHINGTON LINE
(MOST LIKELY EXCLUDING THE IMMEDIATE CITY OF ATLANTA). WITH
FORECAST TEMPS SO CLOSE TO FREEZING THOUGH...AND SOME DEGREE OF
UNCERTAINTY WITH HOW FAR SOUTH FREEZE IS LIKELY...OPTED TO HOLD
OFF ON ANY ISSUANCE OF A FREEZE WATCH...WHICH MAY COME WITH 4AM
FORECAST PACKAGE.

.PREV DISCUSSION... /ISSUED 635 PM EST MON NOV 5 2007/

SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...
HIGH PRESSURE RIDGE OVER THE STATE IS WEAKENING AND MOVING SOUTH.
THIS WILL ALLOW THE TAIL END OF A WEAKENING FRONT TO SWEEP THROUGH
THE STATE FROM THE NORTH TONIGHT THROUGH TUE AFTERNOON. MAY SEE SOME
ISOLATED TO SCATTERED SHOWERS ACROSS NORTH GEORGIA BUT THIS FRONT
REALLY DRIES OUT ONCE IT GET ACROSS THE N GA MOUNTAINS AND GETS INTO
DOWNSLOPING FLOW. THE PARENT LOW ASSOCIATED WITH THIS FRONT IS JUST
NORTH OF MICHIGANS UPPER PENINSULA AND IT IS EXPECTED TO MOVE EAST
INTO NH/VT BY WED AFTERNOON. THE BEST DYNAMICS AND MOISTURE STAY
WELL NORTH OF GA SO THERE WILL BE VERY LITTLE SUPPORT FOR THIS FRONT
AS IT MOVES THROUGH THE AREA. BY 18Z TUE ANOTHER RIDGE OF HIGH
PRESSURE BEGINS BUILDING SE OUT OF THE CENTRAL PLAINS AND SHOULD BE
CENTERED OVER THE MS VALLEY BY 18Z WED. THIS RIDGE WILL HELP TO
CONTINUE OUR DRY SPELL. ALSO COLD DRY AIR WILL MOVE ACROSS THE
REGION BEHIND THIS FRONT THAT WILL MOVE THROUGH TONIGHT. TEMPS IN
THE 50 AND 60S CAN BE EXPECTED OVER THE NEXT 2 DAYS WITH MORNING LOW
MAINLY IN TH E30S WITH SOME ISOLATED MIDDLE TO UPPER 20S ACROSS THE
N GA MOUNTAINS AND IN THE LOWER AREAS AROUND COWETA AND FAYETTE
COUNTIES.

LONG TERM /THURSDAY THROUGH MONDAY/...
THE COLD CANADIAN HIGH WILL REMAIN THE DOMINANT WEATHER FEATURE
THROUGH SUNDAY. IT DOES WEAKEN A BUT THU/FRI AS AN UNORGANIZED WAVE
MOVES SE OUT OF THE GREAT LAKES REGION...BUT IT LOOKS LIKE WE WILL
ONLY SEE INCREASING CLOUDS. ALL IN ALL COOLER TEMPS WITH CONTINUED
DRY WEATHER EXPECTED THROUGH DAY 7.

AVIATION...
RELATIVELY NARROW BAND OF CLOUDS SHOULD ACCOMPANY THE PASSAGE OF A
COLD FRONT THROUGH THE AREA EARLY TUESDAY. LACK OF DYNAMIC LIFT
SHOULD PREVENT THE CLOUD LAYER FROM EXPANDING SPATIALLY...AND
PRECIPITATION IN THE FRONTAL ZONE SHOULD DISSIPATE WITH THE LOSS OF
DAYTIME HEAT. WHEN FRONTAL ZONE ARRIVES IN THE KATL AND KAHN AREAS
AROUND 09Z WE EXPECT SCT TO BROKEN CLOUDS AT 4 TO 6 THOUSAND FEET
WITH A POSSIBLE LOWER LAYER AROUND 25 HUNDRED IN THE WAKE OF THE
FRONT ITSELF. DRIER AIR IS LAGGING SOMEWHAT...BUT SHOULD ARRIVE BY
AROUND 15Z AND BRING IN CLEARING. GRADIENT FLOW...SUBSIDENCE AND
THERMAL MIXING SHOULD CAUSE MODERATELY STRONG GUSTY SURFACE WINDS IN
THE WAKE OF THE FRONT. ARRIVAL TIMES OF CLOUDS WILL OBVIOUSLY BE A
BIT LATER IN THE KCSG AND KMCN AREAS.

.FFC WATCHES/WARNINGS/ADVISORIES...
WIND ADVISORY UNTIL 6 AM EST TUESDAY FOR THE FOLLOWING ZONES:
DAWSON...FANNIN...GILMER...LUMPKIN...MURRAY...PICKENS...TOWNS...
