SPARTANBURG COUNTY AND EAST CENTRAL GREENVILLE COUNTY...

A NEARLY STATIONARY THUNDERSTORM COMPLEX...CENTERED AROUND THE GSP

ADDITION TO SEVERE URBAN FLASH FLOODING...SOME STREAMS SUBJECT TO 
RAPID FLASH FLOODING INCLUDE ABNER CREEK...ROCKY CREEK...BRUSHY 
CREEK...UPPER TRIBUTARIES OF THE ENOREE RIVER...AND EVEN SMALL 
STREAMS IN NEIGHBORHOODS.  AGAIN...THIS HAS BECOME A SERIOUS...LIFE 
THREATENING...URBAN FLASH FLOOD SITUATION.  STAY OFF OF ROADS IN THE 
WARNING AREA...BUT IF YOU ARE IN A FLOOD PRONE LOCATION...MOVE

OVERFLOW AND BREECHES.

DURING HEAVY RAIN EVENTS...SEVERE URBAN FLOODING CAN OCCUR IN AREAS
SUCH AS UNDERPASSES...AND LOW AREAS WHERE WATER TENDS TO COLLECT.
CHILDREN SHOULD BE KEPT AWAY FROM SMALL STREAMS AND STORM DRAINS.

DO NOT DRIVE ACROSS BRIDGES WHICH ARE UNDER WATER. ROADS AT THE ENDS
OF THE BRIDGE MAY WASH OUT OR WEAKEN...AND YOUR VEHICLE MAY FALL INTO
THE RAGING CURRENT. DO NOT RISK YOUR LIFE. BACK UP AND GO ANOTHER
WAY.

138 AM EDT THU AUG 7 2003

...A FLASH FLOOD WARNING CONTINUES UNTIL 330 AM EDT FOR WESTERN 
SPARTANBURG COUNTY AND EAST CENTRAL GREENVILLE COUNTY...

AT 130 AM...RADAR SHOWED VERY HEAVY RAINFALL STILL LOCATED FROM EAST 
OF PELHAM...EXTENDING SOUTHWEST TO FIVE FORKS AND SIMPSONVILLE.  THE 
AXIS OF HEAVIEST RAIN HAS SHIFTED SOUTHEAST FROM THE GREER AND GSP 
AIRPORT AREAS. SOME HEAVY RAIN IN STORMS EXTENDED NORTHEAST ACROSS A 
GOOD PART OF NORTHERN SPARTANBURG COUNTY...FROM DUNCAN TO BOILING 
SPRINGS TO MAYO.  ANOTHER SMALL THUNDERSTORM COMPLEX WAS DEVELOPING 
BETWEEN TRAVELERS REST AND TIGERVILLE.

THE FAST HEAVY RAINFALL HAS CAUSED FLASH FLOODING AROUND GREER AND

PELHAM AREAS. RAINFALL AT THE GSP AIRPORT SINCE MIDNIGHT HAS 
MEASURED 3.15 INCHES.

DURING HEAVY RAIN EVENTS...SEVERE URBAN FLOODING CAN OCCUR IN AREAS
SUCH AS UNDERPASSES...AND LOW AREAS WHERE WATER TENDS TO COLLECT.

SMALL EARTHEN DAMS BREAKING.  THOSE SHOULD BE WATCHED CAREFULLY 
OVERNIGHT.

DO NOT BECOME A FATALITY DO NOT CROSS FLOODED ROADS...THE ROAD COULD
BE WASHED OUT FROM THE FLOW OF THE WATER...AND YOUR CAR COULD BE
SWEPT AWAY BY THE SWIFTLY MOVING WATER.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
905 PM EDT WED AUG 6 2003

KGSP RADAR SHOWS MOST OF THE REMAINING CONVECTION CONFINED TO THE NC
FOOTHILLS AND THE SOUTHERN PART OF THE CLT METRO AREA. LAPS ANALYSIS
SHOWS MOST OF THE REMAINING SURFACE BASED INSTABILITY LIMITED TO THE
NC PIEDMONT...WHICH STANDS THE BEST CHANCE OF ADDITIONAL PRECIP FOR
THE REST OF THE EVENING. WATER VAPOR IMAGERY SHOWS VORT AXIS MOVING
IN FROM N GA. AS THIS FEATURE SWINGS THROUGH THE REGION OVERNIGHT...
IT COULD TRIGGER ADDITIONAL CONVECTION AT ANY TIME. WILL NOT LOWER
POP BELOW CHANCE RANGE FOR THAT REASON...BUT WILL ADJUST POPS TO
MATCH ONGOING CONVECTION. AS FOR TEMPS...AREAS OF THE LOWER SC
PIEDMONT ARE ALREADY AT FCST LOWS OWING TO COOL POOL IN THE WAKE OF
EARLIER CONVECTION. WILL TWEAK TEMPS DOWN THERE BY A DEGREE...BUT
WILL LEAVE TEMPS ALONE ELSEWHERE.

.GSP...
GA...NONE.
NC...NONE.
SC...NONE.

ANOMALOUS UPPER LEVEL LONGWAVE TROUGH TO REMAIN OVER EASTERN USA
THROUGH EARLY PART OF PACKAGE...WITH RIDGE TO W. CONVECTION IN N AL
THIS AFTERNOON TRACKING E TOWARD GA/SC...AND WILL KEEP LIKELY
EVENING POPS THOSE AREAS...WITH CHANCE NC. CONCERNED ABOUT SEVERE
POTENTIAL S PORTION...AND FLOOD POTENTIAL ENTIRE AREA. WILL LEAVE
CHANCE POPS WELL AFTER MIDNIGHT...AS CONVECTION HAS BEEN SLOW TO
DIE OFF. DENSE FOG WAS OBSERVED ACROSS MUCH OF AREA EARLY THIS
MORNING...AND WILL INCLUDE AGAIN THU.

IMPULSE ROUNDING BASE OF TROUGH THU MORE IMPRESSIVE THAN TODAY...AND
WILL CARRY LIKELY POP ENTIRE AREA. WITH UPPER ENERGY STILL UPSTREAM
THU NIGHT...LOW CHANCE POP WILL CONTINUE OVERNIGHT. ANOTHER VIGOROUS
VORT LOBE APPROACHES AREA FRI...TAKING UNTIL LATE NIGHT TO MOVE
THROUGH. CARRIED SLIGHTLY LOWER POP WITH THIS FEATURE AS IT IS A BIT
WEAKER THAN THURSDAY IMPULSE. YET ANOTHER VORT LOBE APPROACHES SAT
INTO SAT NIGHT. THOUGH MORE IMPRESSIVE THAN FRIDAY VORT...WILL KEEP
POP ABOUT LIKE FRI...AS CONFIDENCE DECREASES ON STRENGTH/TIMING.
TEMPERATURES NEAR PERSISTENCE WITH NO CHANGE IN AIR MASS.

EXTENDED FORECAST STARTS MUCH AS EARLY PACKAGE ENDS. BY MON GFS HAS
STRONG SHORTWAVE DIGGING INTO BASE OF TROUGH...CLOSING OF LOW IN S
MS RIVER VALLEY. IF THIS SCENARIO UNFOLDS...W ATLANTIC RIDGE COULD
RETROGRADE OVER AREA...WARMING/DRYING AREA. CURRENT NCEP SOLUTION
