AREA FORECAST DISCUSSION...UPDATE
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
945 PM EST MON DEC 31 2007

.UPDATE...
LATEST SURFACE MAP SHOWS THE COLD FRONT/WIND SHIFT LINE WELL INTO
WEST TN AND CENTRAL MS...WITH COLDER AIR APPROACHING THE MS RIVER
BASIN. THE COLD/WINDY CONDITIONS ARE STILL ON TAP TO ARRIVE AROUND
5-7 AM NEW YEARS MORNING. LIGHT WINDS...CLEAR SKIES AND A DAMP
GROUND COULD RESULT IN SOME PATCHY FOG DEVELOPING OVER THE NEXT FEW
HOURS...BUT THIS THREAT SHOULD BE SHORT-LIVED AS SW WINDS ARE
EXPECTED TO PICKUP SLIGHTLY JUST AHEAD OF THE FRONT...THEN THE FRONT
SWEEPS THRU ENDING THE THREAT. LATEST TEMP & DEWPOINT SPREADS ACROSS
MUCH OF THE FORECAST AREA ARE 4 TO 7 DEGREES...EXCEPT FOR A FEW LOW
LYING AREAS. THEREFORE...FOG MAY NOT HAVE A CHANCE TO DEVELOP BEFORE
THE WINDS PICK UP. THE MORE LIKELY AREAS WOULD BE THE EASTERN HALF
OF THE STATE WHERE WINDS WILL BE SLOWER TO INCREASE...BUT THIS
THREAT SHOULD DIMINISH BY 2-3 AM. WILL NOT UPDATE TO MENTION THE
PATCHY FOG JUST YET...BUT WILL MONITOR CLOSELY FOR THIS POTENTIAL
AND UPDATE IF NECESSARY. OTHERWISE... REST OF FORECAST LOOKS ON
TRACK AT THIS TIME.  /39

.......................ORIGINAL AFD..............................
.SHORT TERM /TONIGHT THROUGH WEDNESDAY NIGHT/...
PROGRESSIVE FLOW PATTERN TO CONTINUE...BUT THE SHORT TERM WILL
FEATURE A SHARP STRENGTHENING OF THE POLAR VORTEX OVER THE EASTERN
HALF OF THE U.S. FROM THE LATER PERIODS OF THE SHORT TERM INTO THE
BEGINNING OF THE LONG TERM. THIS CHANGE WILL BRING THE AREA A GOOD
SHOT OF COLD...MODIFIED ARCTIC AIR AS WE HAVE NOT SEEN IN SOME TIME
AS A LARGE 1052MB SFC HIGH SPREADS SE FROM THE ROCKIES INTO THE
SC/SE U.S. BY MID WEEK. THE SYSTEM THAT WILL INITIALIZE THIS CHANGE
WILL BE A SHORT WAVE AND ASSOCIATED SFC LOW PRESSURE AREA...WHICH
WILL MOVE RAPIDLY FROM THE OH VALLEY INTO PA OVERNIGHT. STRONG COLD
ADVECTION WILL SPREAD SE TUE AS THE POLAR VORTEX DEEPENS FAR SOUTH
INTO THE MID-ATLANTIC. HOWEVER...UPSTREAM PACIFIC ENERGY WILL KEEP
THE FLOW PROGRESSIVE AND NOT ALLOW THE POLAR VORTEX TO LINGER LONG
OVER THE EASTERN U.S. BY THU...THE EASTERN U.S. UPPER TROUGH HAS
SHIFTED OFF THE COAST AND A SHORT WAVE RIDGE SPREADS FROM THE PLAINS
OVER THE EASTERN U.S. NONETHELESS...WHILE BRIEF...SOME RATHER COLD
TEMPS CAN BE EXPECTED MID-WEEK...AS 850MB TEMPS PLUMMET INTO THE
-18C RANGE ACROSS N GA. THE 0C LINE IS ALL THE WAY DOWN TO S FL BY
THU. THE COLDEST TEMPS FOR MUCH OF OUR CWA WILL OCCUR WED AND THU
MORNING...FIRST AS A RESULT OF AN ALBERTA CLIPPER...THEN THU AS
THE LARGE SFC HIGH SETTLES OVER THE AREA. THE LARGE...1040MB+
SPRAWLING SFC HIGH WILL TAKE MOST OF THE REMAINDER OF THE WEEK TO
SPREAD FROM THE SOUTHERN PLAINS ACROSS THE SE...KEEPING DRY
WEATHER IN PLACE THROUGH AT LEAST FRI. A MODEST WARMING TREND
BEGINS BY FRI AS THE COLD ARCTIC AIR MASS RETREATS QUICKLY TO THE
NE UNDER THE INCREASING ZONAL FLOW.

CONCERNS FOR THE SHORT TERM ARE THE POTENTIAL FOR FOG DEVELOPMENT
AGAIN TONIGHT...WIND ADVISORY CONDITIONS FOR TUE...AND POTENTIAL FOR
-SHSN IN THE N GA MOUNTAINS LATE TUE-WED. WITH RESPECT TO FOG
DEVELOPMENT...THE AIR MASS IS FINALLY BEGINNING TO DRY WITH
DEWPOINTS DROPPING INTO THE 30S. ADDITIONAL DRYING THROUGH THE
OVERNIGHT WILL BE MINIMAL. HOWEVER...WITH THE UPPER TROUGH AND SFC
REFLECTED FRONT/WIND SHIFT EXPECTED TO PASS THROUGH AROUND
MIDNIGHT...INCREASING WINDS SHOULD OFFSET ANY POTENTIAL FOR FOG
WIDESPREAD DENSE FOG DEVELOPMENT AS OBSERVED THIS MORNING. PATCHY
FOG IS POSSIBLE ACROSS THE SE/SC AREAS WHERE THE WIND SHIFT WILL
REACH LAST AND SOME DECOUPLING MAY OCCUR. NOT ENOUGH AT THIS POINT
TO WARRANT A DFA.  FOR WIND...TIGHT PRESSURE GRADIENT DEVELOPS
ACROSS THE AREA TUE...ESPECIALLY AFT 18Z AND CONTINUING ON INTO
THE NIGHT AND WED MORNING. LOCAL WIND ADVISORY CRITERIA IS
MARGINALLY MET AT A COUPLE OF STATIONS...BUT MOSTLY AFT 18Z. SINCE
THE BULK OF STRONG WINDS MAY ACTUALLY HOLD OFF UNTIL LATE
TUE/EARLY WED...PREFER TO HOLD OFF ON ISSUING A WIND ADVISORY.
HOWEVER...DO PLAN TO ISSUE AN SPS HIGHLIGHTING THE COLDER
CONDITIONS AND THE WIND. FINALLY...ALTHOUGH MOISTURE QUITE
LIMITED...STRONG COLD ADVECTION OF THE TYPE PROGGED FOR TUE
AFTERNOON/EVENING AND OROGRAPHIC LIFTING TYPICAL OF SHSN SCENARIOS
IN THE NE GA MOUNTAINS...MANY OF WHICH IN THE PAST HAVE CAUGHT US
OFF GUARD. WILL CONTINUE MENTION OF -SHSN FOR LATE TUE/TUE NIGHT
NE MOUNTAINS. ANY ACCUMULATION WOULD BE SPOTTY AND NOT WORTH
MENTIONING AT THIS POINT...BUT WILL AGAIN MENTION IN SPS.
FINALLY...WIND CHILL VALUES IN THE NORTHEAST MOUNTAINS WILL BE
NEAR ZERO OR BELOW EARLY WED...NEARING CRITERIA FOR A WIND CHILL
ADVISORY. LATER SHIFTS WILL NEED TO MONITOR.

.LONG TERM /THURSDAY THROUGH MONDAY/...
LARGE...SPRAWLING MODIFIED CANADIAN SFC HIGH WILL SPREAD FROM THE SC
PLAINS ACROSS THE SE FROM WED-FRI...THEN MOVE OFF THE
MID-ATLANTIC/SE U.S. COAST BY SAT. PROGRESSIVE ZONAL FLOW ALOFT
DOMINATES THE EXTENDED PERIODS. A BROAD AREA OF LOW PRESSURE IN THE
WESTERN/CENTRAL U.S. PROMISES TO SEND SOME WEAK RIPPLES IN THE WSW
FLOW ALOFT ACROSS THE SE U.S. BY THE WEEKEND. THIS IS OFTEN A VERY
DIFFICULT SITUATION TO TIME THIS FAR OUT...BUT PCPN AMOUNTS ARE
USUALLY NEGLIGIBLE AND OFTEN OVER DONE BY THE MODEL THIS FAR OUT.
IMMEDIATELY THEREAFTER...A LARGE SUBTROPICAL RIDGE BUILDS OFF THE SE
U.S. COAST SHUNTING THE DYNAMICS AND MOISTURE FURTHER NORTH OUT OF
THE CWA BY MON. THIS RIDGE BUILDS IN RESPONSE TO A DEEP TROUGH
DIGGING INTO THE SOUTHERN PLAINS. THIS PATTERN WOULD BRING
UNSEASONABLY WARM TEMPS BACK TO THE AREA AT THAT TIME. THE DEEP
SOUTHERN PLAINS U.S. TROUGH THAN TAKES ON A NEGATIVE TILT AND
ROTATES THROUGH THE MID-SOUTH BY THE MID PART OF NEXT WEEK...WHICH
WOULD HAVE THE POTENTIAL TO BRING A SEVERE WEATHER OUTBREAK TO THE
SE U.S. ENTIRELY TOO FAR OUT TO BUY OFF ON THIS YET...BUT BEARS
WATCHING. IN THE MEANTIME...EXPECT MUCH BELOW NORMAL TEMPS AT THE
BEGINNING OF THE EXTENDED TO TRANSITION TO ABOVE NORMAL/MUCH ABOVE
NORMAL BY THE LATER PART OF THE WEEKEND AND EARLY NEXT WEEK. WILL
RETAIN MENTION OF LOW CHANCE POPS NORTH FOR THE WEEKEND...OTHERWISE
DRY CONDITIONS EXPECTED THROUGH THE ZONE EXTENDED PERIODS.

&&

.FIRE WEATHER...
WIDESPREAD ONE INCH RAIN AMOUNTS SUN HAVE LEFT FUELS WET. WITH LOW
EVAPORATION AT THIS TIME OF YEAR...STRONG WINDS WILL NOT LOWER
FUEL MOISTURES ENOUGH FOR CRITICAL FIRE WEATHER CONDITIONS TO BE
MET TUE...AND PROBABLY NOT EVEN WED. WILL NEED TO WATCH
THU...HOWEVER...AS DEWPOINTS IN THE SINGLE DIGITS COMBINE WITH
TEMPS WARMING INTO THE 40S AND 50S AND DRYING FUELS TO PUSH FIRE
WEATHER CONDITIONS CLOSER TO CRITICAL VALUES.

&&

.AVIATION...
EXPECTING LIGHT SOUTHWEST WINDS TO PROVIDE ENOUGH MIXING TO PREVENT
FOG FROM DEVELOPING AHEAD OF APPROACHING COLD FRONT. HOWEVER...THERE
DOES APPEAR TO BE A WINDOW OF OPPORTUNITY FOR FOG AROUND THE KMCN
AREA. WINDS THERE WILL BE QUITE LIGHT THROUGH THE EVENING.
RADIATIONAL COOLING OVER WET GROUND APPEARS LIKELY. THERE IS DOUBT
AS TO WHETHER THE BOUNDARY LAYER WILL HAVE TIME TO SATURATE PRIOR TO
WINDS PICKING UP AHEAD OF COLD FRONT...HOWEVER. ACROSS THE AREA...IF
WINDS DO PREVENT FOG FROM FORMING OVERNIGHT...THE MAIN OPERATIONAL
ISSUE WILL BE WINDS. HIGH PRESSURE BUILDS IN RAPIDLY AND COLD AIR
WILL RUSH ACROSS THE STATE AS THE PRESSURE GRADIENT TIGHTENS. GUSTS
TO 25 TO 30 KTS LOOK LIKELY DURING THE COURSE OF THE DAY TUESDAY.
