...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 945 AM EDT FOR
BERKELEY COUNTY...

AT 929 AM EDT...NATIONAL WEATHER SERVICE DOPPLER RADAR CONTINUED TO 
INDICATE MODERATE TO HEAVY RAINS FALLING ACROSS THE CENTRAL AND 
SOUTHERN PARTS OF THE COUNTY. BETWEEN 2 AND 6 INCH OF RAIN HAS 
FALLEN ACROSS THIS AREA SINCE 7 AM AND ANOTHER INCH COULD FALL 
THROUGH 945 AM. FLASH FLOODING HAS ALREADY BEEN REPORTED IN A NUMBER 
OF AREAS THIS MORNING...SO ANY ADDITIONAL RAINFALL WILL ONLY

MOST FLOOD DEATHS OCCUR IN AUTOMOBILES. NEVER DRIVE YOUR VEHICLE INTO
AREAS WHERE THE WATER COVERS THE ROADWAY. FLOOD WATERS ARE USUALLY
DEEPER THAN THEY APPEAR. JUST ONE FOOT OF FLOWING WATER IS POWERFUL
ENOUGH TO SWEEP VEHICLES OFF THE ROAD. WHEN ENCOUNTERING FLOODED
ROADS MAKE THE SMART CHOICE...TURN AROUND...DONT DROWN.

TO REPORT SIGNIFICANT FLOODING...PLEASE CONTACT THE NATIONAL WEATHER
SERVICE IN CHARLESTON TOLL FREE AT 1-888-383-2024 OR EMAIL YOUR

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON SC
732 AM EDT TUE AUG 28 2007

.SYNOPSIS...
A WEAK FRONTAL BOUNDARY WILL LINGER NEAR THE NORTHERN FRINGES OF
THE FCST AREA TODAY AND DISSIPATE BY WED. A WEAK LOW PRES SYSTEM
WILL DEVELOP OFF THE NC COAST TODAY AND DRIFT S TONIGHT BUT REMAIN
WELL OFF THE COAST THROUGH THU. THEN...A COLD FRONT WILL PUSH
THROUGH THE REGION FRI INTO SAT...BEFORE DISSIPATING S OF THE
REGION BY SUN. HIGH PRES MOVES BACK IN FOR THE START OF NEXT WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
LINE OF SHOWERS AND ISOLATED THUNDERSTORMS WILL SLOWLY SLIDE SOUTH
THROUGH THE CWA TODAY. AGAIN WILL SEE HEAVY RAIN AS THE MAIN HAZARD AS
PWATS REMAIN AROUND 2.25 INCHES AND THE STEERING FLOW REMAINS
WEAK. HIGHS WILL GENERALLY TOP OUT AROUND 90 DEG AWAY FROM THE
IMMEDIATE COAST...ALTHOUGH AS HAPPENED YESTERDAY...ANY LOCALES
THAT SEE SIGNIFICANT CLOUD COVER WILL SEE HIGHS A BIT COOLER.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
A WEAK AREA OF LOW PRES WILL DEVELOP OFF THE NC COAST THIS EVE AND
SLOWLY DRIFT S THROUGH WED. DRIER AIR ON THE BACKSIDE OF THIS LOW
WILL FILTER INTO THE REGION...SIGNIFICANTLY REDUCING OUR RAIN
CHANCES...ESPECIALLY ACROSS OUR SC ZONES. LOWS TONIGHT WILL BE IN
THE LOWER TO MID 70S AWAY FROM THE COAST. HIGHS WED WILL TOP OUT
AROUND 90 DEG AGAIN...BUT SOME MID 90S ARE POSSIBLE WELL INLAND.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
MADE VERY FEW CHANGES TO THE SENSIBLE WEATHER FROM THE PREVIOUS
PACKAGE AS THE TREND LOOKS SIMILAR. POPS LOOK LOWEST ON THURSDAY
AND FRIDAY WITH BUBBLE HIGH MOVING IN...THEN POPS RAISING BACK
TOWARDS CLIMO AS THE NEXT WEAK FRONT APPROACHES AND DEEP MOISTURE
AGAIN INCREASES. TEMPS WITHIN A FEW DEGREES OF NORMAL THROUGH THE
PERIOD.

ONLY FLY IN THE OINTMENT IS THE TENDENCY OF MODELS NOW TO DEVELOP A
WEAK LOW IN THE WESTERN ATLANTIC ON THE FRONT SAGGING THROUGH THE
AREA WED NGT. BOTH GFS AND NAM KEEP THE SYSTEM FAR ENOUGH OFFSHORE
AT THIS POINT TO HAVE MINIMAL EFFECT OVER LAND AREAS...AND WITH MID
LEVEL FLOW OUT OF THE NORTH TO NORTHWEST...I THINK THAT SOLUTION IS
REASONABLE.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
SHOWERS ALREADY AT CHS THIS MORNING CREATING MVFR CIGS AND VSBYS.
THIS ACTIVITY SHOULD BREAK BY MID MORNING. THE ACTIVITY SHOULD
INCREASE FURTHER SOUTH TOWARD SAV DURING THE DAY AS WEAK BOUNDARY
SLIPS SOUTHWARD AND SOME HEATING HAS A CHANCE TO KICK IN.

EXTENDED AVIATION OUTLOOK...VFR CONDS WILL PREVAIL THROUGH MUCH
OF THE EXTENDED PERIOD...OUTSIDE OF SCT AFTN/EVE SHWRS/TSTMS AND
PRE-DAWN SHALLOW GROUND FOG.

&&

.MARINE...
ISOLATED TO SCATTERED THUNDERSTORMS WILL DEVELOP ALONG THE LAND
BREEZE THROUGH THE REMAINDER OF THE MORNING HOURS. MEANWHILE... A
WEAK SFC TROF/BNDRY WILL LINGER JUST N OF THE WATERS THROUGH TODAY
AND HAVE LITTLE TO NO SIGNIFICANT PRESSURE GRADIENTS ASSOCIATED
WITH IT. ALSO...A WEAK AREA OF LOW PRES IS FORECAST TO DEVELOP OFF
THE NC COAST TODAY AND DRIFT S THROUGH WED BUT REMAIN WELL
OFFSHORE. THUS...EXPECT WINDS TO REMAIN BELOW HEADLINE CRITERIA
THROUGH WED. SEAS WILL HOLD AROUND 2 FT WITHIN 20 NM AND 2-3 FT
ACROSS THE 20-60 NM LEG OF THE GA WATERS.

WEDNESDAY NIGHT THROUGH SATURDAY...AFTER SEASONABLY TAME WINDS AND
SEAS THROUGH FRIDAY...WINDS AND SEAS ARE EXPECTED TO PICK UP IN
THE OFFSHORE WATERS THIS WEEKEND AS A SURFACE HIGH BUILDS OFF THE
MID ATLANTIC COAST AND A WEAK LOW SPINS IN THE WESTERN ATLANTIC.
FOR NOW...FORECAST KEEPS WIND SPEEDS AND SEA HEIGHTS BELOW
CRITERIA THAT WOULD REQUIRE HEADLINES...BUT IF THE LOW GETS A BIT
STRONGER...WE MAY REACH INTO SCEC IN THE OFFSHORE WATERS BY LATER
SUNDAY OR MONDAY.

&&

.CHS WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
SC...NONE.
MARINE...NONE.
