...A FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 445 PM EDT FOR
MECKLENBURG AND CABARRUS COUNTIES...

AT 332 PM EDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED 
THAT 3 TO 4 INCHES OF RAIN HAS FALLEN ACROSS AN AREA FROM AROUND 
CHARLOTTE TO AROUND CONCORD. LIGHT TO MODERATE RAIN WILL CONTINUE 
ACROSS THE WARNED AREA FOR ANOTHER 30 TO 60 MINUTES AND ADDITIONAL 
RAINFALL AMOUNTS OF UP TO HALF OF AN INCH WILL BE POSSIBLE. 

FLOODING IS CURRENTLY ONGOING...ESPECIALLY ACROSS THE CHARLOTTE AREA 
INCLUDING FREEDOM DRIVE AND WILKINSON BOULEVARD. OTHER AREAS OF 
FLOODING INCLUDE CLANTON ROAD AND WEST BOULEVARD...AS WELL AS NORTH 
GRAHAM STREET AND WEST 28TH STREET. MOTORISTS SHOULD AVOID THESE 
AREAS...AS WELL AS ANY OTHER ROADS THAT ARE BLOCKED BY HIGH WATER 
CONDITIONS...AND USE EXTRA CAUTION THROUGH THE MID TO LATE AFTERNOON 
HOURS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO CROSS
SAFELY. MOVE TO HIGHER GROUND.

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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
1100 AM EDT THU JUL 9 2009

.SYNOPSIS...
A WEAK STATIONARY FRONT WILL REMAIN NEAR THE AREA TODAY. THE FRONTAL
BOUNDARY WILL MOVE SOUTHWARD FRIDAY. HIGH PRESSURE WILL BUILD IN
FROM THE NORTHEAST BUT WEAKEN AS A COLD FRONT APPROACHES FROM THE
NORTHWEST ON SUNDAY. THIS FRONT WILL LINGER NEAR THE AREA INTO THE
MIDDLE OF THE WEEK.

&&

.NEAR TERM /THROUGH TONIGHT/...
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS HAVE DEVELOPED ACROSS
THE NC ZONES THIS MORNING. CONVECTION COVERAGE SHOULD GRADUALLY
INCREASE OVER THE CWA EARLY THIS AFTERNOON...FAVORING THE NC MTNS
AND FOOTHILLS. RECENT W/V IMAGES INDICATE THAT A MOISTURE
DISCONTINUITY OVER EAST TN WILL MOVE OVER SRN APPALACHIANS THIS
AFTERNOON. THIS FEATURE SHOULD AID THE FORMATION OF MTN SHRA/TSRA
BETWEEN 17Z-20Z AND STORM MOTIONS SHOULD CARRY THE CONVECTION SLOWLY
EAST ACROSS THE FOOTHILLS AND PIEDMONT. THE SLOW CELL MOTIONS MAY
RESULT IN LOCALIZED AREAS OF EXCESSIVE RAINFALL. IN ADDITION...CAPE
VALUES MAY SUPPORT A FEW STRONG UPDRAFTS...RESULTING IN A MARGINAL
HAIL/WIND THREAT. I WILL INCREASE POPS TO LIKELY TO HIGH CHC ACROSS
THE NC MTNS AND FOOTHILLS WITH A CHC ACROSS THE UPSTATE OF SC AND NE
GA THIS AFTERNOON. OVERALL...CONDITIONS SHOULD REMAIN MOSTLY
CLOUDY...SCT TO NUM SHRA/TSRA...WITH HIGH TEMPS SLIGHTLY BELOW
NORMAL.

AS THE UPPER TROUGH AXIS SLOWLY SHIFTS EAST...AND THE ATMOSPHERE
STABILIZES...SHOWERS WILL GRADUALLY WANE DURING THE EVENING...WITH
CHANCE POPS CONTINUING THROUGH ABOUT 06Z.

&&

THE AREA FRI NITE...BUT WEAKENS SAT AND SAT NITE AS EAST COAST TROF
BUILDS. AT THE SFC...HIGH PRESSURE RIDGE BUILDS INTO THE AREA FROM
THE NORTHEAST WHILE WEAK LOW PRESSURE SYSTEMS MOVE ALONG THE STALLED
FRONT ALONG THE GULF COAST. THE SFC RIDGE AXIS REMAINS FAR ENUF
NORTH FRIDAY..THAT MUCH OF THE AREA WILL BE IN UPSLOPE FLOW BETWEEN
THE RIDGE AXIS AND SFC LOW. THE UPSLOPE FLOW COMBINED WITH WEAK
INSTABILITY WILL LEAD TO SCT CONVECTION OVER THE MTNS AND ISOLATED
ELSEWHERE. THIS CONVECTION WILL DISSIPATE DURING THE EVENING. HIGHS
FRI AND LOWS FRI NITE CONTINUE BELOW NORMAL.

SFC RIDGE BECOMES CENTERED OVER THE AREA SATURDAY AS FRONTAL SYSTEM
APPROACHES FROM THE NORTHWEST. MID LEVEL TEMPS WARM HELPING CREATE A
CAP OUTSIDE OF THE MTNS. MID LEVEL TEMPS COOL A LITTLE OVER THE MTNS
DURING THE AFTERNOON ERODING CAP. THIS WEAK INSTABILITY COMBINED
WITH DIFFERENTIAL HEATING SHOULD LEAD TO ISOLATED CONVECTION THERE.
THIS CONVECTION SHOULD DISSIPATE DURING THE EVENING. KEPT FCST DRY
AFTER MIDNIGHT EVEN THOUGH FRONTAL SYSTEM IS APPROACHING SINCE ANY
FORCING FROM THE FRONT SHOULD REMAIN TO OUR NORTHWEST. HIGHS
SATURDAY WARM A LITTLE TO NEAR NORMAL WITH LESS CLOUDS AND
CONVECTION. LOWS SAT NITE ALSO WARM TO NEAR NORMAL.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
AS OF 315 AM THURSDAY...THE GFS AND THE ECMWF REMAIN FAIRLY CLOSE
EARLY IN THE EXTENDED THEN DIVERGE TOWARD THE END. BOTH MODELS SHOW
A COLD FRONT CLOSING IN ON THE AREA SUNDAY...THEN MOVING INTO THE
AREA MONDAY. THE ECMWF LEAVES THE FRONT STALLED OVER THE AREA
TUESDAY WHILE THE GFS SPLITS THE FRONT AND TAKES THE EASTERN SECTION
OFF THE COAST AND MOVES THE WESTERN SECTION NORTH OF THE AREA AS A
WARM FRONT. THE ECMWF DOES THIS ON WEDNESDAY WHILE THE GFS KEEPS US
IN THE WARM SECTOR WITH THE FRONT WELL NORTH OF THE AREA. GIVEN
THESE DIFFERENCES...HAVE MADE ONLY MINOR CHANGES TO THE FCST...
KEEPING THINGS CLOSE TO THE PREVIOUS HPC SOLN. THIS MEANS DIURNAL
CONVECTION SUNDAY...CHC MTNS/SLIGHT CHC EAST...THEN SCT NON DIURNAL
CONVECTION MON THRU TUE. SLIGHT CHC POP RETAINED FOR WED. HIGHS
REMAIN NEARLY STEADY RIGHT AROUND NORMAL WHILE LOWS INCREASE TO A
LITTLE ABOVE NORMAL THRU THE PERIOD.

&&

.AVIATION /15Z THURSDAY THROUGH MONDAY/...
AT KCLT...SHOWERS WILL PERSIST IN THE VCNY OF THE AIRFIELD THROUGH
MUCH OF THE DAY...BEFORE TAPERING OFF DURING THE EVENING. ALTHOUGH
OCCASIONAL RAIN (WITH ACCOMPANYING MVFR VISBY) MAY FALL AT THE
TERMINAL THROUGHOUT THE NEXT 12 HOURS...IT/S IMPOSSIBLE TO SAY WHEN
THESE BRIEF WINDOWS OF PRECIP WILL OCCUR...SO VCSH WILL BE CARRIED.
TS SHOULD ALSO DEVELOP DURING THE AFTERNOON...SO A CB GROUP WILL BE
INCLUDED BY 18Z.
