AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
743 PM EDT WED AUG 22 2007

.SYNOPSIS...
AN UPPER RIDGE WILL REMAIN OVER THE SOUTHEAST THROUGH THE END
OF THE WEEK...BEFORE A COLD FRONT APPROACHES THE WESTERN CAROLINAS
LATE IN THE WEEKEND. THE FRONT WILL BECOME STATIONARY OVER THE
REGION AND SLOWLY DISSIPATE EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH THURSDAY/...
THE UPPER RIDGE WILL SLOW ITS RETROGRESSION AND BUILD NORTHEAST
THROUGH THURSDAY...WITH ITS AXIS ALONG THE APPALACHIANS. UPPER LEVEL
ENERGY WILL DROP SOUTH ALONG THE EAST SIDE OF THIS RIDGE... FAVORING
CONVECTION ALONG THE INTERSTATE 77 CORRIDOR...WHILE DIFFERENTIAL
HEATING TRIGGERS CONVECTION IN THE MOUNTAINS...BOTH LATE TODAY AND
AGAIN ON THURSDAY. VERY SMALL POPS WILL BE CARRIED DOWN THE
INTERSTATE 77 CORRIDOR EVEN LATE TONIGHT AS THE MODEL SHOW MOISTURE
LINGERING THERE ALONG THE VORT TRACK.

TEMPERATURES ARE FORECAST TO BE A BIT LOWER TONIGHT AND THURSDAY
THAN THEY WERE TODAY...ESPECIALLY IN THE EAST...AS HEIGHTS HAVE
FALLEN EAST OF THE RETROGRADING RIDGE...AND A NORTHEAST WIND SETS
UP BEHIND A SURFACE TROUGH NOW OVER THE AREA. GUIDANCE VARIES WILDLY
ON MAXIMUM TEMPERATURES THURSDAY...WITH THE MAV IN THE UPPER
90S...THE MET 10 DEGREES LOWER...AND THE FWC IN THE MIDDLE. THE MAV
HAS HAD A HISTORY OF OVERFORECASTING THIS HEATWAVE...BUT WITH ONLY
SMALL HEIGHT FALLS...THE CURRENT FORECAST...BETWEEN THE MAV AND
FWC...WILL BE CUT BY ONLY ONE DEGREE. DEW POINTS WILL BE HIGHER THAN
RECENTLY...MORE LIKE CLIMATOLOGY...BUT THE HEAT INDEX WILL BE WELL
UNDER HEAT ADVISORY CRITERIA.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
THURSDAY NIGHT INTO EARLY FRIDAY...LOW LEVEL UPSLOPE FLOW AND HIGH
RH VALUES SUGGEST AT LEAST PARTLY CLOUDY SKIES WITH A SLIGHT CHC OF
SHOWERS AND TSTMS ALONG THE BLUE RIDGE ESCARPMENT. MIN TEMPS WILL BE
CLOSE TO WHAT WE HAVE SEEN OVER THE LAST WEEK (LOWER 70S PIEDMONT).

FRIDAY...UPPER RIDGE TRIES TO BUILD IN ACROSS THE SOUTHEAST...AND
LOW LVL THICKNESSES BEGIN TO CREEP UP A BIT. WITH RIDGE AXIS
BASICALLY DIRECTLY OVER THE CWFA...CONVECTION WILL BE SCARCE ONCE
AGAIN. HOWEVER...WITH A LITTLE MORE LOW LVL MOISTURE THAN PREVIOUS
DAYS...CAPES LOOK REALLY HIGH (ESP OVER THE MTNS) WITH THE NAM
GREATER THAN THE GFS. MAX TEMPS WILL STILL BE SIMILIAR TO THURSDAY
(MIDDLE 90S PIEDMONT/ 80S MTN VALLEYS).

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
A WEAK COLD FRONT APPROACHES THE AREA FROM THE OHIO VALLEY
SATURDAY...AS SOUTHEAST CONUS RIDGE WEAKENS. SFC HIGH PRESSURE
PUSHES OFFSHORE...WITH A SOUTHERLY COMPONENT TO THE LOW LVL FLOW.
THIS SHOULD ALLOW FOR SOME LOW LVL MOISTURE TRANSPORT OUT AHEAD OF
THE FRONT. THE 12Z/22 GFS LIKE SO MANY OTHER RUNS OF LATE HAVE
PUSHED BACK THE MORE NORMAL TEMPERATURES. HOWEVER...WITH SFC HIGH
PRESSURE BECOMING ESTABLISHED OFF THE EAST COAST...LOW LVL FLOW
SHOULD STILL SUPPORT AT LEAST AN INCREASED CHC OF AFTN CONVECTION.
THOUGH...IT STILL LOOKS ISOLATED TO SCATTERED IN NATURE. THE LATEST
TEMP GRIDS HAVE MAX TEMPS GENERALLY IN THE UPPER 80S TO LOWER 90S
ACROSS THE PIEDMONT (A FEW DEGREES LOWER THAN THE 12Z/22 MEX TEMPS).

&&

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
MAINLY VFR CONDITIONS ARE EXPECTED THE NEXT 24 HOURS. ISOLATED
CONVECTION HAS BEEN AVOIDING THE TERMINALS THIS EVENING...AND THIS
TREND IS EXPECTED TO CONTINUE AS COVERAGE DIMINISHES. FOG
DEVELOPMENT IS EXPECTED AT KAVL TOMORROW MORNING...WITH A BRIEF
PERIOD OF IFR EXPECTED AROUND SUNRISE. OTHERWISE...INCR NORTHEAST
FLOW WILL BRING SOME LOW LEVEL MOISTURE INTO THE NC FHILLS AND
PIEDMONT TOMORROW MORNING. IT IS DIFFICULT TO SAY IF THIS WILL
RESULT IN LOW STRATUS DEVELOPMENT TOMORROW MORNING...BUT THE
POTENTIAL IS THERE. FOR NOW...WE WILL SIDE WITH GUIDANCE TREND OF
KEEPING LOW CIGS AWAY FROM THE TERMINALS...BUT WE DID INCLUDE FEW009
AT KHKY DURING THE PRE-DAWN HOURS.

ISOLATED TO WIDELY SCATTERED AFTERNOON CONVECTION AND LIGHT MORNING
FOG WILL BE POSSIBLE THROUGH THE REMAINDER OF THE WEEK...ESPECIALLY
IN THE MTNS. COVERAGE OF CONVECTION MAY INCREASE OVER THE WEEKEND...
AS A FRONT APPROACHES FROM THE NORTHWEST.

&&

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