AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREENVILLE-SPARTANBURG SC
718 PM EDT THU JUN 2 2011

.SYNOPSIS...
WEAK HIGH PRESSURE WILL MOVE ACROSS THE MID ATLANTIC REGION THROUGH
SATURDAY...BEFORE A WEAK FRONTAL BOUNDARY APPROACHES FROM THE NORTH
ON SUNDAY. UPPER RIDGING WILL REMAIN IN CONTROL OVER THE DEEP SOUTH
THROUGH THE MIDDLE OF NEXT WEEK.

&&

.NEAR TERM /THROUGH FRIDAY/...
PROFILES ARE STABILIZING ACROSS THE REGION WITH THE LOSS OF DAYTIME
HEATING. A LINGERING LINE OF CONVECTION WILL RIDE SOUTHEAST ALONG A
FRONTAL BOUNDARY DRAPED JUST SOUTH OF THE CHARLOTTE METRO AREA.
LIKELY POPS WILL BE NEEDED ALONG INTERSTATE 77 THIS EVENING...BUT
CAN BE DROPPED QUICKLY WITH THE PASSAGE OF THE LINE. CONVECTIVE
DEBRIS SHOULD STEADILY THIN OVERNIGHT. LOWS WILL BE ONLY A LITTLE
ABOVE NORMAL OVER NC DUE TO THE DRIER AIR MASS MOVING IN FROM THE
NORTHEAST. THE DRIER AIR MASS SHOULD NOT REACH NE GA AND UPSTATE
SC...SO ABOVE NORMAL LOWS WILL CONTINUE THERE. EXPECT SOME MTN
VALLEY FOG TOWARD DAYBREAK...WITH PATCHY FOG ALSO POSSIBLE IN THE
AREAS RECEIVING HEAVY RAIN TODAY.

THE FRONTAL BOUNDARY SHOULD CONTINUE TO PUSH SW ACROSS THE CWFA ON
FRIDAY...WITH DRIER AIR CONTINUING TO SPILL IN FROM THE NE. SOME
DIFFERENCE PERSISTS BETWEEN THE NAM AND GFS SOLUTIONS IN HOW FAR SW
THE DRIER AIRMASS CAN PENETRATE. A MODEL BLEND SUGGESTS THAT THE
MTNS AND THE UPSTATE/NE GA WILL ONCE AGAIN BECOME UNSTABLE FRI
AFTERNOON...BUT WITH CAPE VALUES NOT BE AS HIGH AS THE PAST FEW DAYS
GIVEN THE COOLER TEMPS AND DEW POINTS. A SHORT WAVE WILL MOVE OVER
THE AREA WHICH COULD PROVIDE FORCING TO BREAK ANY CAP.
THEREFORE...WILL GO WITH CHC POP WEST OF AVL AND THE NE GA/UPSTATE
MTNS...WITH SLIGHT CHC REST OF THE NC MTNS AND WEST OF I-26 IN THE
UPSTATE AND NE GA. SVR STORMS WILL BE POSSIBLE AGAIN WITH STEEP LOW
LEVEL LAPSE RATES AND AN INCREASE IN SHEAR. HIGHS WILL BE AROUND 10
DEGREES ABOVE NORMAL WEST AND ONLY A FEW DEGREES ABOVE NORMAL EAST.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
AS OF 200 PM THURSDAY...THE AXIS OF THE UPPER RIDGE EXTENDING FROM
THE STRONG UPPER ANTICYCLONE OVER THE MS VALLEY WILL ROTATE ACROSS
THE WESTERN CAROLINAS ON SATURDAY. AS THE RIDGE AXIS MOVES
ACROSS...AN AREA OF NVA COMBINED WITH SOUNDINGS FEATURING VERY WARM
MID LEVELS WILL CREATE AN ENVIRONMENT QUITE HOSTILE TO THE
DEVELOPMENT OF DEEP CONVECTION. AS SUCH...I HAVE REMOVED THE
MOUNTAIN SLIGHT CHANCES I INHERITED. TEMPS ON SATURDAY WILL WARM
BACK UP INTO THE LOW 90S EVERYWHERE OUTSIDE THE MOUNTAINS.

ON SUNDAY...THE UPPER ANTICYCLONE CENTER WILL RETROGRADE OVER THE
SOUTHERN AND CENTRAL PLAINS. THIS WILL ALLOW A BACKDOOR FRONTAL
BOUNDARY TO SAG SOUTHWARD INTO WESTERN NC. WITH THE UPPER RIDGE
SUPPRESSED FURTHER TO THE WEST AND THE BOUNDARY IN THE
VICINITY...DIURNAL CONVECTION CHANCES APPEAR HIGHER THAN ON
SATURDAY. SOUNDINGS INDICATE THAT THE ATMOSPHERE WILL BE LESS
FAVORABLE FOR THUNDERSTORM DEVELOPMENT THE FURTHER SOUTH AND WEST
YOU GO FROM THE NORTHERN MOUNTAINS AND FOOTHILLS. THEREFORE...CHANCE
POPS WILL BE ADDED IN THESE AREAS...DECREASING TO SLIGHT CHANCE OR
LESS ACROSS THE FAR WESTERN NC MOUNTAINS AND THE SOUTHERN TIER OF
THE UPSTATE. ALTHOUGH THE UPPER RIDGE AND ANTICYCLONE GET SUPPRESSED
TO THE WEST...UPPER HEIGHTS ARE VERY SIMILAR TO SATURDAY AND LOW
LEVEL THICKNESSES ARE ACTUALLY HIGHER. THIS WILL YIELD TEMPS INTO
THE MID 90S OUTSIDE THE MOUNTAINS...LOW 90S IN THE MOUNTAIN VALLEYS.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
AT 1 PM EDT THURSDAY...THE MODELS ARE IN BASIC AGREEMENT ON AN UPPER
RIDGE AXIS MOVING FROM THE PLAINS ON MONDAY...TO THE EASTERN THIRD
OF THE NATION BY THURSDAY. A BACK DOOR COLD FRONT WILL BE LOCATED TO
OUR SOUTH ON MONDAY...WITH HIGH PRESSURE TO THE NORTH. THIS FRONT
WEAKENS AND MOVES FARTHER SOUTH BY TUESDAY. WEDNESDAY AND THURSDAY
FEATURE HIGH PRESSURE CENTERED TO OUR SOUTH...WITH OUR AREA IN THE
WARM SECTOR TO THE SOUTH OF A FRONT IN THE NORTHEAST. SMALL POPS
WILL BE MAINLY CONFINED TO SAVANNAH RIVER VALLEY MONDAY AND
TUESDAY...CLOSEST OT THE DEPARTING FRONT...MIGRATING TO THE
MOUNTAINS WEDNESDAY AND THURSDAY...WHERE DIFFERENTIAL HEATING AND
OROGRAPHIC EFFECTS WILL COME INTO PLAY. TEMPERATURES WILL
RUNS SEVERAL CATEGORIES ABOVE NORMAL UNDER THE UPPER RIDGE...EVEN
BEHIND THE COLD FRONT ON MONDAY AND TUESDAY.

&&

.AVIATION /23Z THURSDAY THROUGH TUESDAY/...
AT KCLT...THE APPROACHING LINE OF THUNDERSTORMS AT ISSUANCE TIME IS
RIDING SE ALONG THE FRONTAL BOUNDARY AND SHOULD MAINLY MISS THE
AIRFIELD JUST TO THE SOUTH. WILL STILL NEED BRIEF TEMPO THUNDER WITH
SOME GUSTS FROM THE WSW AS THE LINE MOVES BY. OTHERWISE...FEW TO SCT
CUMULUS WITH SCT TO BKN CIRRUS WILL LINGER TONIGHT...WITH JUST FEW
CU OR STRATOCUMULUS ON IMPROVING NE FLOW EARLY FRIDAY.

ELSEWHERE...THE THUNDER POTENTIAL HAS ENDED ACROSS THE TERMINAL
FORECAST AREA. EXPECT FEW TO SCT CUMULUS WITH CIRRUS CEILINGS EARLY
TONIGHT...WITH MAINLY LINGERING FEW TO SCT CUMULUS THROUGH FRIDAY.
WINDS WILL BE FROM THE NE AND IMPROVE SLIGHTLY THROUGH THE
PERIOD...EXCEPT LIGHTER AT KAVL. MVFR FOG SHOULD BE RESTRICTED TO
KAVL OVERNIGHT...WITH TEMPO IFR LIKELY AGAIN TOWARD DAYBREAK.

OUTLOOK...DIURNAL ISOLATED THUNDERSTORMS WILL BE POSSIBLE EACH
AFTERNOON AND EVENING...WITH EARLY MORNING MTN VALLEY FOG LIKELY AS
WELL.

&&

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