AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
138 AM EDT SUN NOV 7 2010

.PREV DISCUSSION... /ISSUED 950 PM EDT SAT NOV 6 2010/

UPDATE...
NO CHANGES NEEDED TO THE ZONES AT THIS TIME. MIN TEMPS APPEAR TO BE
ON TRACK FOR A FREEZE AT MOST LOCATIONS TONIGHT. ONLY REAL QUESTION
IN ONGOING FORECAST IS IN THE EXTENDED PERIODS...NAMELY FRI. IF
ECMWF IS CORRECT...UPPER TROUGH WILL STILL BE WELL BACK IN TX AT
THAT TIME...WITH A STRONG RIDGE HOLDING OVER OUR AREA. THUS...IF
THIS HOLDS...POPS FOR FRI CAN PROBABLY BE POSTPONED IN LATER ZONE
FORECASTS. THE MON-TUE PERIOD FOLLOWING LOOK RATHER VOLATILE ON BOTH
MODELS...HOWEVER.

19

PREV DISCUSSION... /ISSUED 353 PM EDT SAT NOV 6 2010/

SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/...
SHORT TERM WILL BE DOMINATED BY HIGH PRESSURE AT THE SURFACE. THE
HIGH AMPLITUDE TROUGH SITUATED ALONG THE EASTERN CONUS WILL CONTINUE
TO SHIFT TOWARD THE EAST AND WILL MOVE OFF THE EASTERN SEABOARD INTO
THE ATLANTIC ON SUNDAY AS SURFACE HIGH PRESSURE CONTINUES TO BUILD
IN ACROSS THE SOUTHEAST. THIS SURFACE RIDGE WILL REMAIN IN PLACE
THROUGH THE SHORT TERM. UPPER LEVEL RIDGING PATTERN BUILDS INTO
THE CWA BY MONDAY. NAM/GFS/ECMWF ARE ALL IN GOOD AGREEMENT WITH THE
SHORT TERM PATTERN.

LOWS THIS MORNING WERE IN GENERAL WARMER THAN
GUIDANCE/FORECAST...WITH MET DOING BETTER THAN THE MAV. LEANED
TOWARD THE MET FOR LOW TEMPS BUT MAV/MET BLEND FOR MAX TEMPS. TEMPS
WERE MARGINAL FOR THE FREEZE WARNING FRIDAY NIGHT AND WILL BE RIGHT
AROUND FREEZING AGAIN SATURDAY NIGHT...THUS WILL CONTINUE FREEZE
WARNING FOR SATURDAY NIGHT. SINCE WE ARE NOT FORECASTING A KILLING
FREEZE SATURDAY NIGHT AND LOWS WILL DROP TO 32 OR BELOW AGAIN ON
SUNDAY NIGHT OVER NORTH AND PORTIONS OF CENTRAL GEORGIA...HAVE GONE
AHEAD AND ISSUED A FREEZE WATCH FOR THIS AREA.

LONG TERM /TUESDAY THROUGH SATURDAY/...
HIGH PRESSURE WILL CONTINUE TO DOMINATE IN THE LONG TERM THROUGH
AT LEAST THURSDAY. AFTER THIS...LARGE DIFFERENCES ARE OBSERVED
BETWEEN THE GFS AND ECMWF. THE GFS DRAGS A SHORT WAVE INTO THE
OHIO VALLEY AND A FRONT INTO GEORGIA ON FRIDAY AND THEN CLEARS THE
CWA OUT ON SATURDAY. HOWEVER...THE ECMWF IS SLOWER WITH THIS
SYSTEM AND DEVELOPS AN UPPER LEVEL LOW OVER THE SOUTHWEST AND
PUSHES IT INTO THE CENTRAL PLAINS BY SATURDAY WITH THE ASSOCIATED
COLD FRONT MOVING THROUGH THE MISSISSIPPI VALLEY. DUE TO THESE
DISCREPANCIES...LARGE UNCERTAINTIES REMAIN AT THE END OF THE LONG
TERM.

11

FIRE WEATHER...
10 HOUR FM HAVE BEEN ABLE TO DRY FOR PORTIONS OF CENTRAL
GEORGIA. RH VALUES DIP BELOW TWENTY FIVE PERCENT TOMORROW
AFTERNOON FOR PORTIONS OF CENTRAL GEORGIA AND DURATIONS LOOK TO BE
RIGHT AROUND 4 HOURS. THIS EVENT SEEMS TO BE MARGINAL...BUT HAVE
DECIDED TO UPGRADE TO A RED FLAG WARNING FOR MUCH OF THE AREA THAT
WAS UNDER A WATCH FOR SUNDAY AFTERNOON. THIS IS GENERALLY SOUTH OF
A LINE FROM COLUMBUS TO FORSYTH TO WARRENTON. THE REMAINING AREA
OF THE WATCH HAS BEEN CANCELED.

11

AVIATION...
06Z UPDATE...
VFR CONDITIONS CONTINUING THROUGH THE FORECAST
PERIOD. SKIES GENERALLY CLEAR NEXT TWO DAYS. WINDS WILL BE
NORTH/NORTHWEST IN THE 4 TO 8 KT RANGE. WINDS MAY BRIEFLY GO NE
BETWEEN 12-18Z BUT THEY SHOULD TURN BACK NW AFTER THAT. NO
PRECIPITATION OR RESTRICTIONS TO VSBYS EXPECTED.

//ATL CONFIDENCE...06Z UPDATE...
HIGH ON ALL ELEMENTS EXCEPT MEDIUM ON POSSIBLE TIMING OF WIND SHIFT
TO THE NORTHEAST.
