AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
345 PM EDT THU OCT 8 2009

.SYNOPSIS...
SURFACE HIGH PRESSURE WILL MOVE EAST AND OFF THE MID ATLANTIC
COAST TONIGHT. AS AN AREA OF LOW PRESSURE MOVES THROUGH THE OHIO
VALLEY A COLD FRONT CROSS THE REGION FRIDAY NIGHT INTO SATURDAY
MORNING. HIGH PRESSURE COVERS THE OHIO VALLEY AND MIDDLE ATLANTIC
BY THE END OF THE WEEKEND AND EARLY NEXT WEEK.

&&

.NEAR TERM /THROUGH FRIDAY/...
SOME SHWS HAVE BROKEN OUT IN THE WEAK LIFT AHEAD OF THE MAIN GROUP
OF SHWS ACROSS KY. ATMOSPHERE REMAINS VERY DRY...AND NOT MUCH IF
ANYTHING IS EXPECTED TO SURVIVE TO THE GROUND. THE HIGHEST
ELEVATIONS OF GREENBRIER MAY EXPERIENCE A LIGHT SHOWER/SPRINKLE.
AREA OF MID/HIGH CLDS THROUGH THE MIDWEST...ASSOCIATED WITH DEEP
AND STRONG SW FLOW WILL SPILL INTO THE CWA OVERNIGHT. ALTHOUGH
DEWPOINTS ARE IN THE LOWER 40S CURRENTLY...THESE CLDS AND INC
WILL EVENTUALLY STUNT THE QUICK DROP IN TEMPERATURES THIS
EVENING. A LLVL JET OF ABOUT 50KTS ARRIVING LATE TONIGHT WILL
DELIVER H85 TEMPS NEAR A TOASTY +18C AT H85 BY 12Z FRIDAY. MIN
TEMPS OVERNIGHT ARE WARMER THAN GUIDANCE SAVE LYH/DAN CORRIDOR
WHERE CLDS WILL BE LAST TO ARRIVE.

INITIALLY...INVERSION WILL PREVENT STRONGER WINDS FROM MIXING
DOWN...ALTHOUGH THE HIGHEST SPOTS FROM THE NEW RIVER/SHENANDOAH
VALLEY AND WEST WILL STILL GUST TO 30MPH AFTER MIDNIGHT. ONCE
MIXING BEGINS WITH INSOLATION EARLY FRIDAY...THE STRONGER WINDS
WILL BEGIN TO MIX DOWN ALONG A BLF/JFZ/MKJ LINE. WIND GUSTS COULD
APPROACH NAM BUFKIT MOMENTUM TRANSFER VALUES NEAR 40 KTS IF MID
CLDS ARE THIN ENOUGH TO LET SOME SUNSHINE THROUGH. WILL ISSUE A
WIND ADVISORY SHORTLY FOR THIS COUNTY GROUPING...ALTHOUGH IT MAY
NEED TO BE EXTENDED INTO NW NC LATER TONIGHT. WILL GO AHEAD AND
CONTINUE THE ADVISORY THROUGH THE FRONTAL PASSAGE FRIDAY NIGHT...ALTHOUGH
THERE WILL BE A LULL TOMORROW AFTERNOON. WITH H85 TEMPS AT
+16-18C...DESPITE CLDS...UPPER 70S ALONG THE HIGHLANDS AND MID 80S
THROUGH THE CITIES LOOKS GOOD.

DESPITE SOME ISOLATED SHWS/STORMS AHEAD OF THE MAIN LINE
TOMORROW...MOST OF THE PRECIP SHOULD COME LATE PM EARLY EVENING
FRIDAY. SPC HAS SLT RISK JUST TO THE SW VA BORDER...AND DESPITE
THE LACK OF CAPE/INSTABILITY...IT WILL NOT TAKE MUCH TO GET
STRONGER WIND GUSTS TO THE GROUND CONSIDERING 0-6KM SHR VALUES
NEAR 50 M/S AS FRONT ARRIVES. WILL HIGHLIGHT IN HWO.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
NORTHERN STREAM H5 LOW OVER THE NORTHERN PLAINS AT THE OUTSET MAKES
VERY LITTLE PROGRESS TO THE SOUTHEAST AS STRONG BERMUDA HIGH WITH
596 DM HEIGHTS OFF THE SOUTHEAST COAST REMAINS STRONG. COLD FRONT
APPROACHES EARLY SATURDAY BETWEEN 06-12Z BUT UPPER SUPPORT IS
SHEARED NORTH AND WEST SO EXPECT DIMINISHING COVERAGE OF PRECIP AS
IT CROSSES THE MOUNTAINS. STILL WITH SLOW-MOVING BOUNDARY MOST
PLACES SHOULD SEE RAINFALL BUT NOT VERY IMPRESSIVE
AMOUNTS...GENERALLY LESS THAN 0.25 INCHES IN THE MOUNTAINS WITH LESS
OVER THE PIEDMONT BY EARLY SUNDAY. BOUNDARY MOVES SLOWLY SOUTH WITH
SEVERAL DISTURBANCES ALONG THE BOUNDARY BRINGING PRECIP BACK TO THE
NORTHWEST ON SUNDAY. DIFFICULT TO SAY HOW MUCH WILL FALL THIS FAR
NORTH BUT LEFT HIGHER POPS IN THE SOUTHERN HALF ON SUNDAY WITH
LOWERING POPS THRU THE DAY IN THE NW AS HIGH PRESSURE FROM THE NW
BUILDS IN. NOT ESPECIALLY COOL AIR FOR THE SEASON IN THE WAKE OF
THIS BOUNDARY WITH NEAR SEASONABLE HIGHS IN THE UPPER 50S NW TO
UPPER 60S SE.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
SURFACE FRONT BECOMES STATIONARY WELL SOUTH OF THE CWA ON MONDAY
WITH SEVERAL DISTURBANCES ALONG THE BOUNDARY BUT THE BULK OF THE QPF
LOOKS TO BE SOUTH OF THE CWA. TEMPS FAIRLY SEASONABLE ON MONDAY WITH
H85 TEMPS IN THE +6 TO +10C RANGE TRANSLATING TO UPPER 50S NW AND
UPPER 60S SE FOR HIGHS. BY TUE MIDWEST SFC HIGH BUILDS EAST WITH
COASTAL LOW WELL EAST AND NW SFC FLOW ACROSS THE CWA.

MID-WEEK LOOKS LIKE ZONAL FLOW ALOFT PREVAILS WITH NO MAJOR
PRECIPITATION PRODUCING SYSTEMS. STRONG HIGH PRESSURE OVER THE
CENTRAL CONUS BUILDS EASTWARD IN THE TUE-WED TIME FRAME WITH SOME
SEASONABLY COOL AIR FOR MID-OCTOBER. 12Z GFS BRINGS NEAR 0C AIR TO
THE NORTHERN CWA BY LATER TUESDAY INTO WED. EC MODEL BRINGS SIMILAR
TYPE COLD AIR BUT 12-18 HOURS EARLIER. STILL WITH 1030+ MB SFC HIGH
CENTERED OVER WV COULD BE A CHILLY NIGHT UNDER GOOD RADIATIONAL
CONDITIONS AND PSBL WIDESPREAD FROST EARLY WED. SFC HIGH RETREATS
LATER WED INTO THU WITH CAD KEEPING EAST A BIT COOLER FOR HIGHS WED.
TEMPS REBOUND BY THUR WITH SOUTHERLY FLOW DEVELOPING AHEAD OF
ANOTHER COLD FRONT APPROACHING LATE IN THE WEEK. MODELS DIVERGE SUBSTANTIALLY
AT THAT TIME WITH GFS SHOWING MUCH COOLER AIR BEHIND AND EC MUCH
MILDER.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
HIGH CLDS WILL GRADUALLY FILL IN FROM THE WEST OVERNIGHT.
CONSIDERING CLD COVER AND DRY AIR IN PLACE...VFR IS EXPECTED AT
ALL TERMINALS. A 50KT LLVL JET WILL MOVE INTO SE WEST VA AND
EXTREME SW VA LATE TONIGHT...AND AS THE EVENT NEARS...A WIND SHR
GROUP MAY BE NEEDED INTO THE NEW RIVER VALLEY AS THE LLVL JET
MOVES OVERHEAD. MODEL SOUNDINGS...SPECIFICALLY THE NAM...ARE
AGGRESSIVE WITH MOMENTUM TRSFR WITH 40KT GUSTS AT BLF FRI MORNING.
THICKENING CLDS MAY BE A LIMITING FACTOR...BUT FOR NOW HAVE
INCREASED WIND GUSTS AT ALL TERMINALS...ESPECIALLY DURING THE MID
MORNING HOURS FRIDAY. SOME SHWS MAY APPROACH LWB AT THE END OF THE
TAF PERIOD...BUT LEFT OUT FOR NOW.

MVFR/IFR CIGS EXPECTED ON SATURDAY AS COLD FRONT SLOWLY MOVES
THROUGH THE REGION...AND POSSIBLY INTO SUNDAY AS N TO NE FLOW
REMAINS. EVENTUALLY...CONDS SHOULD IMPROVE INTO MONDAY AND TUESDAY.
