AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
316 PM EST TUE NOV 10 2009

.SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/...
THE REMNANTS OF IDA WILL TRACK EAST ACROSS FLORIDA THROUGH
TOMORROW AIDED BY THE DEEPENING TROUGH MOVING ACROSS THE
SOUTHEAST. SIMILAR TO YESTERDAY AT THIS TIME...GFS AND ECMWF ARE
IN GOOD AGREEMENT WITH THE NAM SOLUTION FAIRLY CLOSE...JUST SLOWER
TO MOVE THE SYSTEM OFF THE EAST COAST ON THURSDAY WHILE THE CANADIAN
IS AN OUTLIER TAKING THE EXTRATROPICAL LOW FURTHER SOUTH
INITIALLY. HAVE LEANED HEAVILY TOWARD TO GFS/ECMWF SOLUTIONS THIS
RUN. ALTHOUGH MOISTURE BEGINS TO TAPER OFF FROM WEST TO EAST
TOMORROW PROXIMITY OF THE UPPER LOW TO EAST GEORGIA WILL KEEP LOW
CHANCE OF RAIN ACROSS THAT AREA AT LEAST THROUGH TOMORROW NIGHT.
AN UPPER LEVEL RIDGE AND SURFACE HIGH PRESSURE WILL BEGIN BUILDING
INTO THE AREA ON THURSDAY.

MODERATE TO HEAVY RAINFALL WILL CONTINUE TO SPREAD ACROSS THE
FORECAST AREA WITH THE HEAVIEST AMOUNTS OVER NORTH GEORGIA WHERE
ADDITIONAL RAINFALL AMOUNTS OF 2 TO 3 INCHES ARE ANTICIPATED.
RAINFALL AMOUNTS THROUGH TOMORROW MORNING WILL BE IN THE 3 TO 5
INCH RANGE ACROSS MUCH OF THE WATCH AREA WITH LOCALIZED HIGHER
AMOUNTS. HAVE CONTINUED THE FLASH FLOOD WATCH THROUGH TOMORROW
MORNING...BUT WOULD NOT BE SHOCKED TO SEE COUNTIES REMOVED LATER
THIS EVENING...PARTICULARLY IN NORTHWEST GEORGIA. AS IDA TRACKS
ACROSS GEORGIA AND INTERACTS WITH A STRONG SURFACE HIGH BUILDING
OVER THE GREAT LAKES AREA...THE SURFACE GRADIENT HAS TIGHTENED
THIS AFTERNOON. SUSTAINED WINDS OF 20 TO 25 MILES AN HOUR WITH
GUSTS GREATER THAN 30 HAVE BEEN REPORTED ACROSS NORTH AND CENTRAL
GEORGIA. AS IDA SHIFTS EASTWARD TOMORROW...WINDS WILL CONTINUE IN
THE 15 TO 25 MILES AN HOUR RANGE DURING THE DAY TOMORROW WITH
MODELS SHOWING WIND SPEEDS OF 30 KNOTS JUST OFF THE SURFACE. HAVE
EXPANDED THE WIND ADVISORY THROUGH THE DAY TOMORROW...AND EXPECT
WINDS TO BEGIN DIMINISHING TO 10 TO 15 MPH TOMORROW EVENING AS
SURFACE HIGH BEGINS BUILDING SOUTHWEST INTO THE GULF COAST STATES.

TEMPERATURES ARE QUITE TRICKY OVER THE FIRST COUPLE OF PERIODS.
WITH CLOUDS AND RAIN ACROSS THE AREA TONIGHT...GUIDANCE ONCE
AGAIN APPEARS TOO COOL...WITH WARMER MAV GUIDANCE BETTER THAN MET
BASED UPON CURRENT CONDITIONS AND LOCAL BIASES. TOMORROW MET IS
WARMER THAN MAV...ALTHOUGH 12Z MAV MUCH WARMER THAN 00Z MAV IN
SOME LOCATIONS. NOT EXPECTING LARGE VARIATIONS BETWEEN LOWS
TOMORROW MORNING AND AFTERNOON HIGHS WITH THE MET LOOKING BETTER
FOR HIGH TEMPERATURES. A BLEND OF MAV/MET LOOKS GOOD BEYOND THE
SECOND PERIOD.

.LONG TERM /FRIDAY THROUGH TUESDAY/...
BY FRIDAY...BOTH ECMWF/GFS MOVE THE SYSTEM OFF THE SOUTHEAST COAST
AND ARE IN GOOD AGREEMENT.  ALTHOUGH THERE ARE MINOR DISCREPANCIES
IN THE EXTENDED SOLUTIONS...THEY ARE IN GENERAL AGREEMENT THAT AS
THE LOW CONTINUES TO MOVE INTO THE ATLANTIC...SURFACE AND UPPER LEVEL
RIDGING WILL BUILD OVER THE FORECAST AREA ON SATURDAY.  THIS WILL
BRING DRY CONDITIONS WITH ABOVE NORMAL TEMPERATURES THROUGH SUNDAY.
GFS AND ECMWF DIVERGE ON HANDLING OF A SHORT WAVE TRAVERSING THE
ROCKIES ON SATURDAY...WITH GFS DEVELOPING A CLOSED LOW OVER THE
DESERT SOUTHWEST SATURDAY NIGHT WITH A SPLIT FLOW AND ECMWF TAKING A
SLOWER PROGRESSION...DEEPENING THE TROUGH AS IT TRACKS ACROSS THE
PLAINS.  THIS LEADS TO RATHER LARGE TIMING DIFFERENCES WITH THE NEXT
SYSTEM...GFS TRACKS THE WEAKER NORTHERN SHORT WAVE ACROSS THE OHIO
VALLEY SUNDAY NIGHT WHICH PUSHES THE SURFACE FRONT ACROSS THE AREA
MONDAY WHILE THE ECMWF IS SLOWER WITH THE BROAD TROUGH...HOLDING OFF
ON THE SURFACE FRONT UNTIL MONDAY EVENING.  IN ANY CASE...CONFIDENCE
IN DAY 6 AND 7 FORECAST ARE QUITE LOW. MOISTURE RETURN WITH EACH
SOLUTION IS NOT ALL THAT IMPRESSIVE SO SLIGHT CHANCE POPS SEEM
PRUDENT MONDAY AND MONDAY NIGHT WITH DRY CONDITIONS RETURNING FOR
TUESDAY AS BROAD SURFACE HIGH BUILDS IN BEHIND THE SYSTEM.
