AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
230 PM EDT TUE JUN 7 2011

.SYNOPSIS...
UPPER LEVEL RIDGING WILL BUILD THROUGH THE MIDDLE OF THE WEEK...THEN
MOVE GRADUALLY EAST OVER THE ATLANTIC BY THE END OF THE WEEK. A WEAK
FRONT WILL APPROACH DURING THE WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AT 1830Z...UPPER HIGH WILL SETTLE OVER THE REGION THROUGH WED. EVEN
SO...THE FORECAST IS NOT WITHOUT A COUPLE COMPLICATIONS. WE HAVE
BEEN MONITORING THE MCS THAT MOVED SOUTH OFF OF LAKE ERIE THIS
MORNING...AND IS NOW OVER WV. ALL MODELS FOR THE MOST PART FAILED TO
INTIALIZE THIS FEATURE...AND THEREFORE GUIDANCE DEOS NOT TAKE INTO
ACCOUNT THE POSSIBLE IMPACT ON THE FORECAST OUR AREA. WILL CONTINUE
TO MONITOR AND AM LEANING TOWARD BUMPING UP POPS ANOTHER NOTCH INTO
HIGH CHANCE CATEORY FOR THIS EVENING OVER THE CENTRAL/NORTHERN NC
MOUNTAINS. STILL EXPECT SOME MOUNTAIN VALLEY FOG EARLY WED...BUT
WITH MORE CLOUD COVER TONIGHT THE EXTENT MAY NOT BE AS MUCH AS
THIS MORNING. LITTLE TN VALLEY APPEARS TO HAVE THE BEST CHANCE FOR
SIGNIFICANT FOG.

OTHERWISE...EXPECT A CIRRUS CANOPY FROM THE MCS TO OVERSPREAD THE
AREA FROM THE NORTH THIS EVENING WHICH SHOULD LOCK IN WARM/MUGGY
CONDITIONS FOR THE OVERNIGHT. HAVE ELECTED TO CONTINUE THE IDEA OF
LOWERING POPS AFTER MIDNIGHT. ON WED...EXPECT PLENTIFUL SUNSHINE
AND CONTINUED HOT TEMPS. YOU WOULD THINK UNDER THE UPPER HIGH THAT
CONVECTIVE CHANCES WOULD BE SUPPRESSED. HOWEVER LOOKING AT MODEL
SOUNDINGS...IT APPEARS THAT THE LOW LEVEL CIN WILL BE OVERCOME
DURING THE AFTERNOON IN THE MOUNTAINS WHICH SHOULD ALLOW FOR
SCATTERED THUNDERSTORMS AS CAPES WILL BE IN THE 1500-2000J RANGE.
OUTSIDE OF THE MOUNTAINS...CONVECTIVE CHANCES APPEAR MUCH LESS AS
CIN LOOKS MORE DIFFICULT TO OVERCOME. EXPECT MAX TEMPS IN THE MID-
UPPER 90S OUTSIDE THE MOUNTAINS AND NEAR 90 MANY MOUNTAIN VALLEYS.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
AS OF 130 PM TUESDAY...WHILE IT UNDERGOES SOME DEAMPLIFICATION IN
RESPONSE TO HEIGHT FALLS OVER ERN CANADA...THE UPPER RIDGE WILL
REMAIN OVER THE FA WED NIGHT THROUGH FRIDAY. SCT AFTN TSTMS WILL
DEVELOP OVER THE MTNS BOTH THU AND FRI AFTNS. WITH A LITTLE MORE WLY
FLOW OVER THE REGION ON FRI...AND WITH SOME WEAKENING OF THE
RIDGE...CONVECTIVE COVERAGE SHOULD BE A LITTLE BETTER THAN ON THU.
THOUGH WITH THE LACK OF FORCING...POPS ONLY MAX OUT AROUND 30 TO 35
PERCENT OVER THE HIGHER ELEVATIONS. TEMPS WILL CONTINUE TO RUN ABOUT
10 DEGREES ABOVE NORMAL BOTH DAYS.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
AS OF 1230 PM EDT TUESDAY...THE MID TROPOSPHERIC RIDGE WILL CONTINUE
TO SLOWLY WEAKEN OVER THE REGION ON SATURDAY. WINDS WILL STILL BE
LIGHT WITH THE RIDGE OVERHEAD...THOUGH THERE WILL BE WESTERLY
COMPONENT TO THE FLOW. THE GFS DEVELOPS A CONSIDERABLE AMOUNT OF
CONVECTION OVER THE MTNS...WHILE THE EC IS DRIER. THE FORCING
DOESN/T LOOK TO BE THERE FOR WIDESPREAD CONVECTION...AND LOW CHANCE
POPS OVER THE HIGH TERRAIN AND SLIGHT CHANCE ELSEWHERE IS WHAT I/VE
CARRIED. A TROUGH WILL BEGIN TO DIG ACROSS NEW ENGLAND ON
SUNDAY...WHICH SHOULD PUSH A FRONT THROUGH THE REGION SOMETIME
SUNDAY NIGHT. SHOWER AND THUNDERSTORM ACTIVITY SHOULD BE A LITTLE
MORE WIDESPREAD AHEAD OF OF THE FRONT. A DRIER AIRMASS SHOULD ENTER
THE REGION MONDAY AND TUESDAY AS THE TROUGH STRENGTHENS AND DIGS
ALONG THE EASTERN SEABOARD...PUSHING THE SFC FRONT SOUTH OF THE FA.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
AT KCLT AND ELSEWHERE...GENERALLY A VFR FORECAST FOR ALL AIR FIELDS.
THE EXCEPTION WILL BE KAVL EARLY WED MORNING WHERE AT LEAST MVFR FOG
RESTRICTIONS ARE LIKELY...AND CAN'T RULE OUT A COUPLE HOURS OF
LIFR. HOWEVER...HAVE LECTED NOT TO INCLUDE LIFR WITH THIS TAF
ISSUANCE AS EXPECT AN INCREASE OF HIGH LEVEL CLOUD COVER OVERNIGHT
WHICH MAY CURTAIL THE AMOUNT OF MOUNTAIN VALLEY FOG. WINDS WILL BE
GENERALLY LIGHT SW TO CALM.

OUTLOOK...HIGH PRESSURE WILL DOMINATE THE WEATHER THROUGH SAT WITH
GENERALLY VFR CONDITIONS...EXCEPT FOR IN THE MOUNTAIN VALLEYS WHERE
EARLY MORNING FOG WILL CAUSE RESTRICTIONS. ALSO EXPECT ISOLD DIURNAL
TSTM THREAT TO CONTINUE THRU SAT...MAINLY IN THE MOUNTAINS.

&&

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