1005 AM EDT MON AUG 11 2003

PUBLIC...
THE COMPLEX MID AND UPPER LVL PATTERN CONTINUES TDA WITH THE H5 LOW
SPINNING OVER THE OHIO VALLEY WITH MOSTLY WEAK SHORT WAVE ENERGY
BOTH NE AND S OF OUR CWFA THIS MORNING. 12Z RAOB ANALYSIS INDICATES
SOMEWHAT STRONGER FLOW AT H25 THAN EITHER THE ETA OR GFS PROGGED AT
6 HRS WITH A GENERAL DIFLUENT REGION ACROSS SE GEORGIA AND SERN S
CAROLINA. ORIGINAL THOUGHTS WERE TO NUDGE OUR INLAND POPS TO 50 PCNT
THIS AFTN...ESPECIALLY ACROSS OUR GEORGIA ZONES...BUT DO NOT HAVE
MUCH IN THE WAY OF 06Z GUIDANCE TO BACK IT UP. SINCE NGM MCON PROG
SHIFTS BEST LOW LVL CONVERGENCE TO CENTRAL GEORGIA BY 00Z WILL HOLD
OFF ON RAISING OUR POPS THIS MORNING. FORECAST AFTN HIGH TEMPS LOOK
TO BE ON TRACK WITH BACKING WINDS TO THE S.

MARINE...
OBS INDICATE CONDITIONS ARE SLOWLY DECREASING AFTER SURGE
OVERNIGHT. WILL INITIALIZE WITH LATEST OBS AND DO NOT ANTICIPATE
MUCH CHANGE THIS AFTN IN CONDITIONS. MAY HAVE A LITTLE STRONGER
WINDS NEAR THE COAST UNDER INFLUENCE OF SEA BREEZE BUT PROBABLY NOT
AS STRONG AS YDAY. THINK 10 KT SHOULD HOLD FOR TODAY FOR MOST
WATERS. SEAS SHOULD BE A MAX OF 4 FT OVER THE GA WATERS 20 TO 60 NM
WITH UP TO 3 FT EXPECTED ELSEWHERE.

.CHS...
GA...NONE.
SC...NONE.
