AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHARLESTON WV
336 AM EDT TUE SEP 9 2008

.SYNOPSIS...
A COLD FRONT PASSES THIS AFTERNOON INTO THIS EVENING...BUT THEN
STALLS ALONG THE BLUE RIDGE WEDNESDAY BEFORE WASHING OUT THURSDAY.
HIGH PRESSURE OFF THE EAST COAST RETURNS HUMIDITY AND ABOVE AVERAGE
TEMPERATURES LATE WEEK INTO THE WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
MOISTURE TRANSPORT QUITE EVIDENT IN THE ATMOSPHERE AND IN THE MODELS
THIS MORNING.  RESULT HAS BEEN PRECIPITATION BREAKING OUT QUICKLY
ACROSS THE AREA.  ONE FEED ATTACKING FROM THE S APPEARS TO BE
SUSTAINING ITSELF MAINLY ON LLVL MOISTURE CONVERGENCE...BUT SOME OF
THESE CELLS HAVE BEEN RATHER STOUT.

THE OTHER POINT OF ATTACK IS FROM THE W ON THE APPROACH OF A COLD
FRONT AND ASSOCIATED UPPER LEVEL TROUGH/DIVERGENCE.  AREA IN BETWEEN
CONTINUES TO FILL IN IN RESPONSE TO THE CONVERGENT MOISTURE
TRANSPORT.

USED THE RUC EARLY ON BEFORE TRANSITIONING TO THE WSETA...AND THEN
THE NAM AND FINALLY THE GFS FOR THE LATTER PART OF TONIGHT TO
PRODUCE POPS...WHICH HAVE BEEN CRANKED UP TO CAT FOR THIS MORNING.
THE GFS IS HIGHER ON POPS ACROSS SE WV TOWARD DAWN WED THAN THE
NAM...ON ACCOUNT OF A SOUTHERN STREAM WAVE PRESENT ON THE GFS BUT
ALL BUT ABSENT ON THE NAM12.  TOOK POPS BACK UP THERE AFTER MIDNIGHT
BUT NOT QUITE TO LIKELY AS THE GFS SHOWS.

MOISTURE IN THE NRLY LLVL FLOW WILL LEAD TO LOW CLOUDS IN A
BAND BEHIND THE FRONT...WHERE DRIZZLE IS ALSO POSSIBLE TONIGHT.  A
SHARP CLEARING LINE BEHIND THAT WILL ALLOW RADIATION FOG NW PORTION
OF AREA BEFORE DAWN WED.

HIGHS TODAY ARE MOSTLY A BLEND OF THE NUMBERS...WHICH DIVERGED AT
ONLY A FEW SITES.  DID USE NON DIURNAL TREND WITH THE
CLOUDS...PRECIPITATION AND FRONT.  SE OH MAY RECOVER A BIT THIS
AFTERNOON WHEN THE SUN COMES OUT.  ANY SUNNY BREAKS EARLIER ON
FARTHER S AND E WILL OF COURSE MAKE AN APPRECIABLE DIFFERENCE.  LOWS
TONIGHT LOOKED QUITE REASONABLE WITH LOWEST LOWS N WHERE THE
CLEARING TAKES PLACE.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY/...
SFC BOUNDARY STALLS ALONG THE BLUE RDG WED MAKING FOR A TIGHT CLOUD
GRADIENT.  ROLLED WITH OVC FOR THE HEADWATERS OF THE GRNBR VLY S
INTO THE CNTRL WV MTNS.  BUFR SNDGS SUPPORT L- DUE TO SATURATED
LLVLS COUPLED WITH WEAK UVV IN THE ABOVE AREAS.  H8 MSTR SPILLS INTO
THE EKN-CRW-WIL CORRIDOR DURING THE DAY WED...THEREFORE RAMPED UP
SKY CVR IN THE PREVIOUS MENTIONED LOCATIONS.  OTRW...IT WILL BE
SUNNY AND PLEASANT DAY FM THE OHIO RIVER W AS HIGH PRESSURE BUILDS
ACR THE ERN GRTLKS.  GFS PUSHES LLVL RH FARTHER W THAN THE NAM
WED...BUT DUE TO HIGHER RESOLUTION OF THE NAM BASED CLOUDS OFF IT.

WED NGT AND THUR BAROCLINIC ZONE WASHES OUT ALLOWING FOR SRLY THRU
THE COLUMN.  GFS IS AGGRESSIVE RETURNING QPF TO THE CWA...WHILE
SREF/NAM/ECMWF ARE NOT.  AGAIN...PREFER THE LATTER DUE TO A BETTER
CONSENSUS.  DUE TO THE CLOUDS WE SHOULD SEE LTL IN THE WAY OF
RADIATION FG PER A CANOPY OF MID AND HIGH CLOUDS WITH SCT STRATOCU
UNDERNEATH.  ONLY CHANGES MADE TO TEMPS WAS A SLGT DOWNWARD
ADJUSTMENT IN MAXT WED FM BKW-SUM.

&&

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
SRLY FLOW THRU A GOOD PART OF THE ATMS ALLOWS FOR PLENTY OF
CLOUDS...BUT SLIGHTLY ABV NORMAL WX THRU SAT.  APPEARS WE CAN GET
AWAY WITH A DRY FCST THUR NGT...BUT DUE TO A MID LVL IMPULSES
ROUNDING THE PERIPHERY OF A H5 ANTICYCLONE SCT RW/TRW ARE PSBL W OF
THE OH RVR FRI.  IT APPEARS IKE WILL BE LESS OF A CONCERN IN THE
OUTER PDS...BUT NW FLOW SHALL KEEP THE PERIOD ACTIVE WITH A SERIES
OF BAROCLINIC ZONES AND MID LVL WAVES TRAVERSING THROUGH.  INCREASED
THE PROB OF PCPN IN THE MTNS THIS WKND TO ACCOUNT FOR THE
AFOREMENTIONED FEATURES.  GIVEN THE PALMER INDEX...RAIN IS NOT A BAD
THING.

&&

.AVIATION /07Z TUESDAY THROUGH SATURDAY/...
RAIN DEVELOPING QUICKLY ACROSS THE AREA EARLY THIS MORNING WILL
CAUSE IFR CONDITIONS AT TIMES...ESPECIALLY IN THUNDERSTORMS.
SHOWERS AND THUNDERSTORMS WERE APPROACHING THE OHIO FROM THE
W...WITH INDIVIDUAL CELLS MOVING MORE N THAN E.  THUNDERSTORMS WERE
ALSO ENTERING WV FROM THE S.  MOISTURE TRANSPORT WILL CONTINUE INTO
THE AREA EARLY THIS MORNING...RESULTING IN THE INCREASING COVERAGE
OF RAINFALL.  THE MOST LIKELY TIME FOR IFR IN THUNDERSTORMS IS
DAYBREAK THROUGH ABOUT MIDDAY.

AS THE COLD FRONT MOVES THROUGH THE AREA THIS AFTERNOON AND EARLY
THIS EVENING...FLOW WILL GO FROM S AND THEN SW AHEAD OF THE
FRONT...TO NW...N AND EVENTUALLY NE BEHIND THE FRONT.  CLEARING
WILL GET TO ABOUT CENTRAL WV BY THIS EVENING...WITH SLOW SWD
PROGRESS TONIGHT.  AREAS S AND E OF CRW...TO INCLUDE BKW...WILL HAVE
IFR CLOUDS TONIGHT...WHILE AREA TO THE NW GET IFR OR WORSE FOG ON
RADIATION BENEATH THE CLEAR SKY...ALTHOUGH THIS HOLDS OFF UNTIL 06Z
OR BEYOND. FOR THE MOST PART.

AVIATION OUTLOOK /BEYOND 06Z WEDNESDAY/...IFR WX PSBL IN STRATUS AND
FOG OVER SRN WV LATE TUESDAY NIGHT INTO WEDNESDAY...AND IN FOG NRN
WV DURING THE EARLY MORNING HOURS WEDNESDAY.
