AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
314 AM EST FRI NOV 26 2010

.SYNOPSIS...
A STRONG COLD FRONT WILL PASS THROUGH THE AREA BY FRIDAY
AFTERNOON. COLD AIR WILL MOVE INTO THE AREA TONIGHT AND SATURDAY
ON STRONG GUSTY WEST WINDS. HIGH PRESSURE WILL BUILD INTO THE
REGION LATER IN THE WEEKEND.

&&

.NEAR TERM /THROUGH TONIGHT/...
AS OF 300 AM...PIEDMONT OBS INDICATE THE LOW LEVEL WEDGE HAS
BROKEN IN THE EASTERN PIEDMONT SECTIONS OF THE CWA...AND TEMPS
HAVE RISEN INTO THE MID TO UPPER 50S. MEANWHILE...THE SFC FNT HAS
MOVED EAST OF BLUEFIELD...BUT IS SLOWING DOWN SOME. STILL LOOKS
LIKE THE FNT WILL MOVE TO ABOUT ROA/LYH BY 12Z/700 AM...AND THEN
CLEAR THE DANVILLE AREA BY 15Z/1000 AM. HOWEVER...MOST OF THE RAIN
IS BEHIND THE FRONT...SO AT LEAST THE MORNING HOURS LOOKS WET-
ESPECIALLY IN THE MTNS ALONG AND WEST OF THE BLUE RIDGE. I HAVE
CATEGORICAL POPS FOR MOST OF THE MTNS...AND LIKELY POPS FURTHER
EAST. SHOWERS SHOULD END FROM NORTHWEST TO SOUTHEAST DURING THE
AFTERNOON...ALTHOUGH THE WESTERN SLOPES MAY HAVE SOME LINGERING
LIGHTER SHOWERS INTO THE AFTERNOON...EVEN THOSE SHOULD TAPER OFF
LATE IN THE DAY. THERE IS ENOUGH COLDER AIR MOVING INTO THE MTNS
THAT HIGHER ELEVATIONS OF SE WV WILL LIKELY SEE THE RAIN SHOWERS
CHANGE OVER TO SNOW SHOWERS. THIS WOULD BE MAINLY WESTERN
GREENBRIER COUNTY...AND I HAVE ABOUT AN INCH OF WET SNOW ACCUM
THERE THIS MORNING. ALSO...COLD ADVECTION IS STRONG ENOUGH THAT
TEMPS WILL BE FALLING IN THE WESTERN MTNS- ESPECIALLY SE WV AND
SMYTH/TAZEWELL COUNTIES IN VA. THE REST OF THE MTNS WILL SEE
FAIRLY STEADY TEMPS...WITH A GOOD DROP IN THE LATE AFTERNOON.
HIGHEST ELEVATIONS...ABOVE 3000 FEET...MAY SEE SOME WIND GUSTS TO
NEAR 45 MPH FOR AN HOUR OR TWO THIS MORNING AFTER THE FRONTAL
PASSAGE. THESE STRONGER WIND GUSTS WILL BE SHORT-LIVED AND ISOLATED
ENOUGH THAT A WIND ADVISORY IS NOT NECESSARY.

TONIGHT- AN UPPER SHORT WAVE MOVG ACROSS THE DAKOTAS AT THIS
TIME...WILL PASS ACROSS THE CWA BETWEEN 06Z/100 AM AND 12Z/700 AM.
THIS BRINGS SOME STRONGER WINDS...COLDER AIR AND INCREASED
SUBSIDENCE. THIS LOOKS LIKE A GOOD SET-UP FOR STRONGER WIND GUSTS
TO REACH THE SFC ALONG THE CREST OF THE APPLNS...AND EAST INTO THE
HIGHER ELEVATIONS OF THE BLUE RIDGE. SHOULD BE WIND GUSTS OF 45 TO
50 MPH IN MANY ELEVATIONS ABOVE 2500 FEET...SO WILL ISSUE A WIND
ADVISORY RUNNING FROM 900 PM THIS EVENING...UNTIL NOON SATURDAY.
MODELS SHOW 850 MB TEMPS DROPPING AS LOW AS -8C IN THE MTNS WITH
THE COLD ADVECTION OVERNIGHT. THIS SHOULD BRING WIDESPREAD LOWS IN
THE 20S IN THE MTNS...AND AROUND 30 IN THE PIEDMONT. WITH THE
WIND...WILL BE A COLD NIGHT.

&&

.SHORT TERM /SATURDAY THROUGH MONDAY/...
NW FLOW CONTINUES SATURDAY WITH 8H TEMPERATURES DOWN TO -1 TO -8
FROM SOUTH TO NORTH SATURDAY. WITH THE STRONGEST CAA SATURDAY
MORNING...HIGHS WILL ONLY MANAGE TO REACH THE UPPER 30S TO LOWER 40S
IN THE  MTNS...WHILE SOME DOWNSLOPING WILL HELP THE EAST RISE INTO
THE LOWER 50S.

HIGH PRESSURE WILL BUILD OVERHEAD SATURDAY NIGHT...ALLOWING WINDS TO
BECOME LIGHT. GOOD RADIATIONAL COOLING NIGHT AS TEMPERATURES FALL
WELL INTO THE 20S ESPECIALLY THE MTN VALLEYS.

THE SFC HIGH WILL TRAVEL EAST AND 5H HEIGHT RISE SUNDAY. RETURN WAA
WILL BE MAINLY AFFECTING THE WRN CWA WHERE HIGH TEMPERATURES REBOUND
10-15 DEGREES WARMER THAN SATURDAY WITH THE UPPER 40S IN THE
MOUNTAINS TO THE MID 50S IN THE PIEDMONT.

SURFACE RIDGE OVER THE MID ATLANTIC STATES ON SUNDAY NIGHT WILL
DRIFT NORTHEAST TO OFF THE NEW ENGLAND COASTLINE BY MONDAY NIGHT.
DEEP FULL LATITUDE TROF OVER THE WEST U.S. WILL BE PROGRESSING
SLOWLY EASTWARD...REACHING THE MISSISSIPPI VALLEY BY DAYBREAK
TUESDAY.

&&

.LONG TERM /MONDAY NIGHT THROUGH THURSDAY/...
EXPECT DRY WEATHER TO PERSIST THROUGH MONDAY EVENING. HOWEVER...
INCREASING WARM MOIST ADVECTION IN ADVANCE OF UPPER TROF AND
ATTENDANT SURFACE LOW TO WEST...AND DEPARTING SURFACE HIGH TO
NORTHEAST SHOULD RAPIDLY MOISTEN MUCH OF LOWER AND MID TROPOSPHERE
AS THE NIGHT PROGRESSES. INCREASING UPWARD VERTICAL MOTION FIELDS
RESULTING FROM ISENTROPIC LIFT OVER WEDGE AND LOW LEVEL UPSLOPING
SHOULD BE SUFFICIENT TO WRING OUT SPOTTY DRIZZLE AND/OR SHOWERS
BEFORE DAYBREAK TUESDAY...ESPECIALLY ALONG THE EASTERN FLANKS OF THE
BLUE RIDGE SOUTH OF ROANOKE INTO THE NORTH CAROLINA MOUNTAINS.

APPROACH OF RIGHT ENTRANCE REGION OR UPPER JET AND ASSOCIATED UPPER
DIFFLUENCE COUPLED WITH CONTINUED WARM MOIST ADVECTION/ISENTROPIC
LIFT AND TOPOGRAPHICAL FORCING/UPSLOPING SHOULD ASSURE THAT THREAT
OF SHOWERS WILL INCREASE OVER THE ENTIRE BLACKSBURG FORECAST AREA AS
TUESDAY PROGRESSES INTO TUESDAY NIGHT...WHEN COLD FRONT FINALLY
ARRIVES FROM THE WEST.

BOTH THE ECMWF AND THE GFS SUPPORT THE NOTION THAT THE COLD FRONT
WILL SLOW IN ITS EASTWARD PROGRESSION ON TUESDAY NIGHT AS UPPER
SYSTEM DIGS AND THREATENS TO BECOME NEGATIVELY TILTED AS UPPER FLOW
SLOWLY BACKS. GFS A BIT MORE BULLISH IN THIS SCENARIO...AND
THEREFORE HOLDS ON TO THREAT OF PRECIPITATION WELL INTO WEDNESDAY
BEFORE ENDING FROM THE WEST DURING THE AFTERNOON...WITH THE ECMWF
SOME 3-6 HOURS MORE PROGRESSIVE WITH BACK EDGE OF PRECIPITATION
SHIELD.

TIMING WILL BE CRITICAL TO WHETHER SUFFICIENT COLD AIR ON BACKSIDE
OF SYSTEM CAN BE ENTRAINED TO CHANGE LINGERING PRECIPITATION OVER TO
SNOW BEFORE ENDING. CURRENT FORECAST ALLOWS THIS TRANSITION TO OCCUR
FIRST OVER THE SOUTHWESTERN MOUNTAINS LATE TUESDAY NIGHT...POSSIBLY
REACHING THE CREST OF THE BLUE RIDGE BY DAYBREAK WEDNESDAY.

STRONG COLD ADVECTION FOLLOWING THE PASSAGE OF THE UPPER TROF SHOULD
ALLOW FOR SKIES TO RAPIDLY CLEAR IN DOWNSLOPE AREAS EAST OF THE BLUE
RIDGE ON WEDNESDAY AFTERNOON...BUT PERSISTENT UPSLOPING WINDS WEST
OF THE BLUE RIDGE SHOULD MAINTAIN THE THREAT OF WIDELY
SCATTERED/SCATTERED SHOW AND RAIN SHOWERS IN PREFERRED AREAS THROUGH
WEDNESDAY NIGHT BEFORE ENDING ON THURSDAY.

REGARDLESS...COLDEST AIR OF THE YEAR WILL ARRIVE AS STRONG SURFACE
RIDGE SLOWLY BUILDS EAST INTO THE AREA...MAINTAINING BELOW NORMAL
TEMPERATURES FOR THE REMAINDER OF THE OUTLOOK PERIOD. HPC
TEMPERATURES GUIDANCE LOOKED VERY REASONABLE IN LIGHT OF THE ABOVE
AND WERE USED FOR THE ENTIRE LONG RANGE PERIOD...WITH THE EXCEPTION
OF SOME TWEAKS TO REFLECT LOCAL CLIMATOLOGICAL
BIASES.

&&

.AVIATION /08Z FRIDAY THROUGH TUESDAY/...
PERSISTENT WEDGE WITH ABUNDANT LOW LEVEL MOISTURE TRAPPED UNDER
THE INVERSION WILL ASSURE THAT IFR TO LIFR CONDITIONS PERSIST IN
MOST AREAS EAST OF THE BLUE RIDGE UNTIL LATE TONIGHT. HOWEVER LOW
CLOUDS HAVE AGAIN SHIFTED JUST EAST OF KROA AND EXPECT INTERVALS
OF VFR/MVFR AT TIMES THERE UNTIL THE SHOWERS AHEAD OF THE FRONT
ARRIVE A FEW HOURS AFTER MIDNIGHT WHEN MORE WIDESPREAD MVFR/IFR
LOOKS LIKELY. LIMITED INFLUENCE OF WEDGE WEST OF THE BLUE RIDGE
ALONG WITH CONTINUED DOWNSLOPING WINDS SHOULD ASSURE THAT KBLF AND
KLWB REMAIN VFR UNTIL THE STRONG COLD FRONT AND ASSOCIATED SHOWERS
WITH MVFR TO IFR RESTRICTIONS IMPINGE ON THE AREA FROM THE WEST
BETWEEN MIDNIGHT AND 2 AM. THIS COULD BRING A BRIEF GUST TO OVER
30 KTS WITHIN THE SHOWERS ON THE LEADING EDGE OF THE FRONT ESPCLY
AROUND KBLF AND PERHAPS KLWB SO BUMPED UP SPEEDS.

A STRONG LOW LEVEL JET WILL CONTINUE AROUND 50 KNOTS JUST AHEAD OF
THE ADVANCING FRONT...BRINGING LLWS TO MOST TAF SITES. FRONT
EXPECTED TO MOVE EAST THROUGH KBLF AND KLWB AROUND 07Z/2AM...KROA
AROUND 09Z-11Z/4-6AM...AND KLYH AND KDAN IN 14Z- 16Z/9-11AM TIME
FRAME.

STRONG GUSTY POST-FRONTAL NORTHWEST WINDS WILL OVERSPREAD THE REGION
AS FRIDAY PROGRESSES...CONTINUING INTO FRIDAY NIGHT. FLIGHT
CONDITIONS EXPECTED TO RAPIDLY IMPROVE BACK TO VFR EAST OF THE
BLUE RIDGE WITH ONSET OF DOWNSLOPING WINDS FRIDAY AFTERNOON.
HOWEVER THE LATEST NAM IS A BIT SLOWER TO EXIT MOISTURE OVER THE
SE SO KEPT MVFR CIGS AND AT LEAST A VICINITY SHRA IN A BIT
LONGER OUT EAST. OTRW UPSLOPING WINDS WEST OF THE BLUE RIDGE WILL
SUPPORT AT LEAST LOCALIZED MVFR CEILINGS PERSISTING THROUGH MUCH
OF FRIDAY AFTERNOON AT/NEAR KBLF/KLWB UNTIL SURFACE HIGH NUDGES
FAR ENOUGH EAST TO ALLOW UPSLOPING WINDS TO RELAX...CLEARING SKIES
FOR THE ENTIRE REGION FOR THE WEEKEND THROUGH MONDAY OF NEXT WEEK.

NEXT WEATHER MAKER TO BEGIN ARRIVING FROM THE WEST AND SOUTH MONDAY
NIGHT INTO TUESDAY...BRINGING THE THREAT OF ANOTHER ROUND OF MVFR
TO IFR RESTRICTIONS TO MUCH OF THE AREA LATE MONDAY NIGHT INTO
THE MID WEEK PERIOD.
