AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
950 PM EDT FRI JUN 25 2004

.SHORT TERM...
PRIMARY CONCERN FOR THE UPDATE IS ONGOING FLOOD WATCH AND ADDITIONAL
HEAVY RAIN THREAT.

KGSP 88D LOOPS INDICATE BACK EDGE OF CATEGORICAL SHOWER AND
THUNDERSTORM CVRG ACRS EXTREME NORTHEAST GEORGIA AND EXTRAPOLATION
BRINGS IT ALONG A GSP-AVL LINE AROUND MIDNIGHT. SO IT WOULD SEEM
THAT CHANCES FOR ANY NEW FLOODING AFTER MIDNIGHT WOULD BE LIMITED
FOR NE GA AND THE NW UPSTATE. ACRS THE NC PART OF THE FFA...RAINFALL
TODAY DOES NOT LOOK LIKE IT HAS BEEN HEAVY ENOUGH FOR CURRENT PCPN
TO CAUSE FLOODING. SO...WILL PLAN ON LETTING FFA EXPIRE ON SCHEDULE.

ON THE LARGE SCALE...DEEP OMEGA AND UPPER DIVERGENCE IS PROGGED TO
CONTINUE TO WEAKEN THROUGH 06Z AND INTO THE OVERNIGHT...SO DESPITE
PWATS NEAR 2.00 INCHES ON 00Z SOUNDING AND FAVORABLE UPPER JET
POSITIONING...IT IS INCONCLUSIVE WHETHER FLOODING WILL DEVELOP
WHERE RAINFALL HAS BEEN HEAVIEST TODAY...ALONG AND JUST NORTH OF
I-85...AS PER KGSP STP. SO...WILL ISSUE CAUTIONARY FLOOD STATEMENT
FOR THIS AREA...ROUGHLY GSP-CLT CORRIDOR...THAT SOME HEAVY RAIN
COULD AGGRAVATE HIGH WATER CONDITIONS OVER THE NEXT 4 HOURS.
&&

.PREV DISCUSSION...
ISSUED 320 PM EDT FRI JUN 25 2004
STRONG CONVECTION CONTINUES TO FIRE ALONG DIFFERENTIAL HEATING
BOUNDARY/CONVERGENT AXIS ALONG THE I-85 CORRIDOR. THE ATMOSPHERE HAS
BECOME QUITE UNSTABLE SOUTH OF THIS BOUNDARY...WHERE CAPES NOW
EXCEED 2500 J/KG. MEANWHILE...FORECAST SOUNDINGS NORTH OF THE
BOUNDARY INDICATE 0-3 KM HELICITY IN EXCESS OF 100 M2/S2. THIS HAS
RESULTED IN MODERATE ROTATION IN STORMS WITH THE STRONGEST UPDRAFTS.
ONE OF THE INITIAL STORMS THAT DEVELOPED THIS AFTERNOON...WHICH WAS
ONE OF THE WEAKER ROTATING STORMS OF THE DAY...MAY HAVE PRODUCED A
WEAK TORNADO IN SOUTHERN ANDERSON COUNTY...SO ANY STORMS EXHIBITING
MODERATE ROTATION WILL CONTINUE TO PEAK OUR INTEREST THIS
EVENING.

OTHERWISE...SURFACE FRONT IS PUSHING INTO EAST TENN AT THIS TIME...
WITH WEAK SURFACE WAVE NOTED ALONG THE NORTHERN BORDER OF AL AND GA.
THE HEAVIEST WARM CONVEYOR BELT PRECIP CONTINUES TO AFFECT MAINLY
EAST TENN...AND THIS IS ACTUALLY BEGINNING TO SHIFT SLIGHTLY TO THE
NORTH...AS COVERAGE HAS BEGUN TO DECLINE OVER SOUTHEAST TENNESSEE.
THE MAIN AXIS OF HEAVY RAINFALL WILL CONTINUE TO DRIFT SLOWLY NORTH
WITH THE FRONTAL WAVE THIS EVENING. MEANWHILE...SCATTERED TO
NUMEROUS SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP IN THE
UNSTABLE AIR ACROSS THE PIEDMONT AND FOOTHILLS. WE WILL CONTINUE TO
CARRY CATEGORICAL POPS ACROSS ALL BUT THE SOUTHERN TIER OF
COUNTIES...WHERE HIGH LIKELIES SHOULD SUFFICE. AS FAR AS THE FLOOD
WATCH...ALTHOUGH THE WATCH AREA MAY BE BETWEEN MAXIMA IN RAINFALL...
WITH HEAVIER CONVEYOR BELT PRECIP TO OUR WEST...AND CONVECTIVE
RAINFALL EAST OF THE BLUE RIDGE...RAIN RATES MAY ACTUALLY INCREASE
IN THE WATCH AREA AS THE WEAKENING SURFACE WAVE RIDES UP THE WESTERN
SLOPES. CONSIDERING THE LOW FFG VALUES...WILL LEAVE THE WATCH IN
PLACE THROUGH MIDNIGHT.

THE FRONT WILL MOVE SLOWLY INTO THE AREA TONIGHT...AND WILL RETAIN
CHANCE POPS THROUGH THE OVERNIGHT. TOMORROW...THE FRONT IS EXPECTED
TO HANG UP JUST SOUTH OF THE AREA...AND WILL CARRY CHANCE POPS
ACROSS THE SOUTHERN HALF OF THE CWFA...WITH SILENT 20S NORTH. THE
FRONT IS EXPECTED TO REMAIN NEAR OR JUST SOUTH OF THE AREA THROUGH
EARLY NEXT WEEK...POSSIBLY OSCILLATING NORTH AND SOUTH FROM TIME TO
TIME...SO WILL MAINTAIN CHANCE POPS THROUGH EARLY NEXT WEEK...WITH
HIGHEST POPS ACROSS THE SOUTHERN CWFA.

LANE

WED-FRI...ACTIVE AND MOIST WEATHER PATTERN LOOKS TO CONTINUE THROUGH
LATE NEXT WEEK. STUBBORN AND STRONG WESTERN BLOCKING RIDGE SHOULD
REMAIN THROUGH THE PERIOD AND ALLOW AN UNSEASONABLY COOL HUDSON LOW
TO REINFORCE ITSELF. BASED ON LATEST GFS...BERMUDA HIGH IS EXPECTED
TO REMAIN IN ITS USUAL POSITION...ALBEIT WEAKER THAN NORMAL. THIS
SHOULD PERMIT A COUPLE COLD FRONTS TO PUSH INTO THE REGION AND
BECOME STATIONARY SOMEWHERE ACROSS THE CAROLINAS. SO...WITH A
SUMMERTIME MOISTURE FEED CONTINUING ACROSS THE SOUTHEAST AND LOW
LEVEL FORCING REMAINING HIGH...WILL FORECAST POPS EACH DAY. KEPT MAX
TEMPS AT OR A LITTLE BELOW CLIMO...BASED ON CONTINUOUS CLOUD COVER
AND SLIGHT AIR MASS MIXING EXPECTED.

SBK

NUMEROUS SHOWERS AND THUNDERSTORMS DEVELOPING ACROSS THE PIEDMONT
AND FOOTHILLS WILL REQUIRE COMBINATION OF TEMPO GROUPS FOR TSRA AND
VCTS TO HANDLE TIMING OF MORE SIGNIFICANT WEATHER. LOW CLOUD
CEILINGS SHOULD BE VFR EXCEPT IN THUNDERSTORMS. CONVECTIVE ACTIVITY
MAY NOT DIMINISH UNTIL MIDNIGHT OR THEREABOUTS...AFTER WHICH MVFR
VISIBILITY AND CEILING SHOULD DEVELOP WITH ABUNDANT MOISTURE IN
PLACE ALONG AND TO THE SOUTH OF NEARLY STATIONARY FRONT...WHICH
SHOULD MOVE SOUTH OVERNIGHT ACROSS THE REGION. VISIBILITY SHOULD
IMPROVE IN THE 12Z-15Z TIME FRAME AS WINDS COME AROUND TO N OR NE
DIRECTION BEHIND FRONT...BUT WILL RETAIN MVFR CEILING THROUGH THE
REMAINDER OF THE TAF PERIOD OWING TO EXTENSIVE CLOUDINESS SEEN NEAR
BOUNDARY.
