1256 PM EDT SUN JUL 3 2005

.SHORT TERM (REST OF TODAY)...
HAVE ISSUED A FLASH FLOOD WATCH FOR MUCH OF THE FOOTHILLS...
FOOTHILLS AND WESTERN PIEDMONT THROUGH MIDNIGHT TONIGHT. DWPTS ARE
IN THE LOW 70S WITH AN EASTERLY UPSLOPE FLOW. WITH A FAIRLY STRONG
-- FOR JULY -- SHORTWAVE APPROACHING...CONDITIONS LOOK VERY GOOD
FOR HIGH PCPN EFFICIENCIES AND FOR SOME ANCHORED CELLS. IN FACT
THAT HAS ALREADY BEEN OBSERVED THIS MORNING IN SOME MOUNTAIN
LOCATIONS AND THERE WAS SIGNIFICANT URBAN FLOODING IN TOCCOA GA.
OTHERWISE...WL UP POPS TO CATEGORICAL IN THE NC FOOTHILLS AND
INCLUDE HEAVY RAIN WORDING...AND WL LOWER MAX TEMPS A FEW DEG.

.PREVIOUS DISCUSSION...
(ISSUED 902 AM EDT SUN JUL 3 2005)

SHORT TERM (REST OF TODAY)...
UPGLIDE OVER LLVL COLD AIR DAMMING OVER THE WRN CAROLINAS AND NE
GA IS INCREASING AHEAD OF AN APPROACHING SHORT WAVE. THIS HAS
RESULTED IN WIDESPREAD SHOWERS AND THUNDERSTORMS ALONG AND JUST
NORTH OF THE SFC FRONT. LAPS SOUNDINGS SHOW A FAIR AMOUNT OF
ELEVATED INSTABILITY WELL INTO THE UPSTATE AND CENTRAL
MOUNTAINS...AND LOCAL VAD WIND PROFILER SHOWS ABOUT 4KFT OF
EASTERLY UPSLOPE FLOW. HAVE THEREFORE RAISED POPS TO LIKELY AND
CATEGORICAL OVER MUCH OF THE REGION...EXCEPT THE I-77 CORRIDOR
WHERE EFFECTS OF DEEP ELY FLOW AND ADVANCING SHORT WAVE WL NOT BE
FELT AS STRONGLY FOR A WHILE YET.

PREVIOUS DISCUSSION...
(ISSUED 329 AM EDT SUN JUL 3 2005)

SHORT TERM (TODAY THROUGH TUESDAY)...
COMPLICATED FORECAST FOR DAYS 1-2 GIVEN THE TIME OF THE YEAR. NAM
AND GFS ARE NOISY WITH WHAT APPEARS TO BE ASSOCIATED WITH AN
OVERACTIVE CONVECTIVE PARAMETERIZATION...ESPECIALLY THE GFS. LATEST
SURFACE ANALYSIS SHOWS THE STATIONARY FRONT RUNNING BASICALLY ALONG
I-20 FROM LA TO SC. REGIONAL RADAR SHOWS THAT SHRA/TSTMS HAVE ALREADY
DEVELOPED ALONG THE FRONT OVER THE MIDLANDS AND CENTRAL GA. WV SHOWS
WHAT APPEARS AS AN MCV OVER THE AL/GA LINE AHEAD OF THE MAIN L/W
TROF. H5 TROF WILL APPROACH TODAY WITH SEVERAL EMBEDDED VORTS
ROTATING IN THE VICINITY OF THE CWA. IN ADDITION...H85 UPSLOPE FLOW
WILL ALSO STRENGTHEN THIS AFTERNOON. EXPECT THAT THIS MORNING
CONVECTIVE FOCUS WILL REMAIN ALONG THE STATIONARY FRONT TO THE
SOUTH. STEERING FLOW COULD BRING CELLS ACROSS THE SAVANNAH RIVER
VALLEY BY MID MORNING. SREF INDICATES THAT CAPE SHOULD RANGE FROM
1K-2K J/KG BY THIS AFTERNOON. BY MID DAY CONVECTION SHOULD SPREAD
NORTH INTO THE UPSTATE AIDED BY OUTFLOW BOUNDARIES. AT THE SAME
TIME...HIGH TERRAIN/UPSLOPE SHOULD BEGIN TO SPAWN
CONVECTION...COVERAGE SHOULD PEAK LATE THIS AFTERNOON. WILL
ADVERTISE NUM SHRA/TSTMS ACROSS THE WESTERN HALF OF THE FA WITH
SCT EAST.

L/W TROF AXIS WILL BECOME LESS AMPLIFIED TONIGHT AS IT MOVES EAST
WITH RIDGE BUILDING OFF THE FL COAST. SHRA/TSTM MAY LINGER UNTIL
MIDNIGHT BEFORE COVERAGE DECREASES TO LESS THAN 30%. FOR THE
4TH...MID LEVEL HEIGHTS FLATTEN AS SOUTHERN RIDGE BUILDS AND SLIDES
WEST OVER FL. WEAK BOUNDARY SHOULD CONTINUE TO LINGER SOUTH OF THE
FA WITH BROAD SFC RIDGING EAST OF THE MTNS. WILL ADVERTISE TYPICAL
SUMMER-TIME CHC AS VORT BAND RIDING ALONG THE RIDGE LINE PASSES
OVERHEAD ON MON. BY TUES...MOISTURE PLUME ARRIVES FROM THE WESTERN
EDGE OF THE H5 HIGH AND AHEAD OF SLOW OHIO VALLEY FRONT. EXPECT THE
CWA WILL REMAIN WELL TO THE EAST OF FRONTAL MCS ACTIVITY.
HOWEVER...BUILDING MOISTURE SHOULD SUPPORT DIURNAL SCT SH/TS ON TUE.

LONG TERM (TUESDAY NIGHT THROUGH SATURDAY)...
LITTLE CHANGE EXPECTED FOR THE REST OF THE WEEK. FRONT SLOWLY
PRESSES CLOSER TO THE FA AS ATMOS REMAINS WARM AND MOIST. GOING
TEMPS AND POPS LOOK GOOD AND WILL ONLY MAKE MINOR ADJUSTMENTS.

AVIATION...
SOME PATCHY MVFR FOG ALREADY OCCURRING ACROSS THE CWFA. EXPECT AT
LEAST A BRIEF PERIOD OF MVFR ALL TAF SITES BY MORNING...WITH SOME
IFR FOG POSSIBLE AT KAND WHERE RAIN FELL. MDLS STILL ADVERTISING LOW
LEVEL SELY FLOW AND INCREASING MOISTURE THIS MORNING.
HOWEVER...DISAGREEMENT EXISTS REGARDING CIG HEIGHTS. LOOKS LIKE MVFR
CIGS ARE MOST LIKELY...WITH IFR AT KAVL. VFR CONDITIONS RETURN
BEFORE NOON TODAY...BUT EXPECT LOW VFR CIGS WITH THE LOW LEVEL
MOISTURE AND FLOW. MDLS AGREE ON AT LEAST LIKELY AFTERNOON POP...SO
HAVE PREVAILING SHOWERS AND VCTS DURING THE AFTERNOON. EXPECT VFR TO
BE THE MAIN FLIGHT CATEGORY...UNLESS A TSRA MOVES OVER THE AIRFIELD.
VCTS ENDS...BUT VFR SHRA CONTINUES THRU 06Z. FOR THE 12Z TAFS...WILL
NEED TO CONSIDER AT LEAST MVFR CONDITIONS BETWEEN 06Z AND 12Z.
