.PREV DISCUSSION... /ISSUED 455 AM EDT SUN SEP 7 2008/

SHORT TERM /TODAY THROUGH TUESDAY/...
NAM/GFS PRETTY CLOSE IN THE SHORT TERM. THE H5 RIDGE WILL REMAIN
NEARLY STATIONARY FROM THE ATLANTIC AND ACROSS SOUTH GA/NORTH FL AND
INTO THE NORTHERN GULF THROUGH TUESDAY. THE SURFACE BOUNDARY ACROSS
CENTRAL GA WILL LIFT BACK NORTH AS THE LOW LEVEL FLOW BEGINS TO
RESPOND TO A COMBINATION OF THE SURFACE RIDGE TO OUR NORTHEAST AND
IKE TO OUR SOUTH PRODUCING AN ONSHORE FLOW OFF THE ATLANTIC. THIS
WILL BRING HIGHER DEWPOINTS AND A CHANCE OF SHOWERS AND TSTORMS
DURING THE AFTERNOON AND EVENING ON MONDAY. A H5 SHORT WAVE MOVING
ACROSS THE MIDWEST AND AN ASSOCIATED COLD FRONT WILL MOVE INTO THE
TENNESSEE VALLEY TUESDAY BRINGING A BETTER CHANCE OF THUNDERSTORMS
TO MAINLY NORTH GA TUESDAY.

LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
LONG TERM IS HIGHLY DEPENDENT ON THE TRACK OF IKE ALTHOUGH CONSENSUS
OF THE GFS/ECMWF INDICATES THAT AS IKE MOVES INTO THE GULF THE H5
RIDGE REBUILDS JUST OVER GA AND FL. THIS PUSHES IKE INTO THE WESTERN
GULF LEAVING GA IN THE AFTERNOON AND EVENING TSTORMS THROUGH THE
LONG TERM WITH PLENTY OF ATLANTIC MOISTURE TO WORK WITH. NO BIG
TEMPERATURE SWINGS EXPECTED THROUGH THE LONG TERM.

AVIATION...
LIFR-MVFR FOG THE MAIN PROBLEM FOR SOME AREAS LIKE CSG...AHN AND
MCN. THESE LOWER CONDITIONS SHOULD IMPROVE AROUND MID MORNING OR SO.
AT LEAST MVFR VSBYS POSSIBLE FOR OTHER LOCATIONS AS WELL. OTHERWISE
EXPECTING MAINLY SCATTERED CU DEVELOPING RISING TO 5000-6000 FT.
ISOLATED TO SCATTERED SHOWERS AND T-STORMS EXPECTED OVER CENTRAL GA
MAINLY S AND E OF MCN. SURFACE WINDS RANGING W-N LESS THAN 10 KTS.
