AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
350 AM EDT SUN AUG 17 2008

.SYNOPSIS...
WEAK HIGH PRESSURE WILL PERSIST ACROSS THE CENTRAL APPALACHIANS...AS
A WEAK BOUNDARY REMAINS OVER THE COASTAL PLAIN THROUGH MONDAY.
TROPICAL STORM FAY IS EXPECTED TO BEGIN TO TURN TOWARD THE NORTH
TONIGHT AND MONDAY...AS IT MOVES ACROSS CUBA.

&&

.NEAR TERM /THROUGH TONIGHT/...
NOCTURNAL CONVECTION BEGINNING TO DISSIPATE AS LOW LVL UPSLOPE FLOW
WKNS DURING THESE WEE MORNING HOURS. A POTENT VORT MAX WAS WELL
DEFINED ON W/V AND RUC H5 ANALYSIS OVR THE CWFA AT 06Z. THIS VORT
WILL SLOWLY SHFT E...WITH AN NVA REGIME MOVG OVR THE AREA DURING THE
DAY. THIS AFTN...THERE MAY BE ENUF SUBSIDENCE TO KEEP THE AREA
CAPPED. THE GFS SHOWS LOW LVL MOISTURE REMAINING ACRS THE
PIEDMONT...AS LOW LVL FLOW VEERS TO SELY. THE SREF IS MORE LIKE THE
NAM IN KEEPING THE AREA RELATIVELY STABLE (PROB OF CAPE > 1000 J/KG
< 20%). BOTH THE NAM AND SREF STILL INDICATE A FEW ISOLD MTN SHWRS
AND TSTMS...HWVR. SO I TWEAKED GRIDS TO INCLUDE ENTIRE FA IN SLGT
CHC POP (WITH LOW-END CHC ALONG CAE CWFA BORDER). MAX TEMPS WILL BE
ABOUT THE SAME AS YDA (70S TO LWR 80S MTNS AND UPR 80S
FOOTHILLS/PIEDMONT).

TONIGHT...MODEL T-SECTIONS SHOW NOCTURNAL SELY LLJ DEVELOPING LIKE
WE HAD THIS MORNING (SATURDAY NIGHT). THE GFS HAS LESS INSTBY AFTER
00Z THEN WHAT WAS ANALYZED WITH YDA/S CONVECTION. ALSO...ONLY SOME
WK RIPPLES IN THE UPR LVLS WILL BE THERE TO SUPPORT CONVECTION. SO
JUST A SLGT CHC POP FOR THE BLUE RIDGE ESCARPMENT FROM I-40 AND
S...TO THE UPR SAVANNAH VLY.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
AS OF 330 AM SUNDAY...LTL CHG WAS MADE TO THE SHORT TERM...AS AIR
MASS CHGS LTL...AND MODELS ARE IN FAIR AGREEMENT THRU THIS PERIOD.
ALL EYES ON TS FAY...WHICH IS EXPECTED TO BE INVOF HAVANA...CUBA BY
ERLY MONDAY. WK SFC HI PRES WILL PERSIST ACRS THE OH VLY TO THE MID
ATLANTIC...RESULTING IN ELY LOW LVL FLOW. A COASTAL FRONT/TROF OF
SORTS WILL STRENGTHEN FROM GA TO CAPE HATTERAS...OUT AHEAD OF FAY.
THIS LOOKS TO BE THE FOCUS FOR CONVECTION...WHICH SHUD KEEP MOST OF
THE DEEPER MOISTURE OUT OF OUR AREA UNTIL LATER IN THE WEEK. SO
GENERALLY ONLY A FEW ISOLD SHWRS/TSTMS CAN BE EXPECTED AT MOST ON
MONDAY...WITH A SLIGHTLY HIER CHC ON TUESDAY...AS SAID BNDRY BEGINS
TO ADVANCE INLAND A BIT. OTRW...TEMPS SHUD STAY ABOUT NORMAL THRU
TUESDAY. AGAIN...THIS IS A RATHER LOW CONFIDENCE FCST...AS THE
STRENGTH AND LOCATION OF FAY MAY RESULT IN MORE SUBSIDENCE OVR THE
AREA TUESDAY (AND THUS DRIER CONDITIONS).

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
AS OF 330 AM SUNDAY...THE LATEST NHC FCST AND THE 00Z/17 GFS ARE IN
GOOD AGREEMENT FOR THE TRACK OF TS FAY. THE 2 AM NHC FCST PEGS FAY
AS A DEPRESSION OVR ELBERT COUNTY AT 00Z/22. SO I BLENDED THE 00Z
MEX TO RAISE POPS WEDNESDAY AND THURSDAY TO MATCH THE STRONGER
CONFIDENCE IN FAYS LIKELY AFFECT ON THE WX ACRS THE CWFA. FOR
NOW...A MID- TO HIGH-END CHC BOTH DAYS...WITH MAX TEMPS ADJUSTED
DOWN A CAT OR TWO. ATTM...QPF AMTS ARE STILL HIGHLY UNCERTAIN.
HWVR...IF THE CURRENT FCST TRACK VERIFIES...OUR AREA SHUD SEE
SIGNIFICANT WIDESPREAD RAINFALL BY LATE NEXT WEEK. A MENTION OF THIS
RAINFALL POTENTIAL WILL BE PLACED IN THE HWO.

&&

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
WEAK BNDRY WILL DROP SOUTH ACROSS THE AREA TONIGHT. STRONG STORMS
HAVE DEVELOPED ALONG THE BNDRY BETWEEN KHKY AND KCLT. STORMS WILL
LIKELY BUILD BACK INTO KHKY THE NEXT COUPLE HOURS. I THINK THEY WILL
STAY NORTH OF KCLT...BUT IT WILL BE CLOSE. MANY SITES WILL SEE FOG
OVERNIGHT WITH THE HIGHER DEWPOINTS...THOUGH HIGH CLOUDS SHOULD KEEP
IT FROM BECOMING DENSE.

LIGHT NORTHEAST FLOW THIS MORNING WILL BECOME LIGHT SOUTHEAST THIS
AFTERNOON. PLENTY OF CU WILL DEVELOP WITH DAYTIME HEATING...BUT I
WON/T INCLUDE CB/S QUITE YET AS IT LOOKS A LITTLE MORE STABLE TODAY
AND THIS EVENING.

OUTLOOK...SFC FRONT REMAINS JUST S OF AREA MON. PRECIP CHANCE
APPEARS MINIMAL THROUGH THE PERIOD. TROPICAL STORM FAY MAY APPROACH
FROM THE S AROUND MID WEEK.

&&

.GSP WATCHES/WARNINGS/ADVISORIES...
GA...NONE.
