AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
209 AM EDT WED OCT 10 2012

.SYNOPSIS...
A COOL WEDGE OF HIGH PRESSURE WILL GRADUALLY WEAKENING FROM WEST
TO EAST AHEAD OF AN APPROACHING COLD FRONT OVERNIGHT INTO EARLY
WEDNESDAY. THE COLD FRONT SHOULD THEN CROSS THE AREA LATER
WEDNESDAY RESULTING IN GUSTY WESTERLY WINDS BUT LITTLE RAINFALL.
STRONG HIGH PRESSURE BUILDS IN FROM THE WEST FOR THE END OF THE
WEEK FOLLOWED BY YET ANOTHER WEAK COLD FRONT BY THE WEEKEND.

&&

.NEAR TERM /THROUGH TODAY/...
AS OF 944 PM EDT TUESDAY...

HAVE MADE A TWO TO THREE DEGREE INCREASE IN EXPECTED LOW
TEMPERATURES EAST OF THE CREST OF THE BLUE RIDGE OVERNIGHT. LATEST
SATELLITE TRENDS AND MODEL DATA SUGGEST CLOUD COVER MAY BE A BIT
MORE ROBUST...AND THUS HELP MAINTAIN SLIGHTLY MILDER TEMPERATURES.
OTHERWISE...HAVE MADE ONLY MINOR TWEAKS TO HOURLY
TEMPERATURE...DEW POINT...WIND AND SKY COVER GRIDS THROUGH THE
EARLY MORNING HOURS.

AS OF 636 PM EDT TUESDAY...

ONLY MINOR TWEAKS TO THE ONGOING FORECAST GRIDS. HAVE ADJUSTED
TEMPERATURE...DEW POINT AND SKY COVER BASED UPON THE CURRENT
OBSERVATIONS AND EXPECTED TRENDS THROUGH THE EVENING.
OTHERWISE...THE FORECAST IS ON TRACK BASED UPON THE AFTERNOON
ISSUANCE.

AS OF 210 PM EDT TUESDAY...

WEDGE CONTINUING TO SLOWLY WEAKEN THIS AFTERNOON WITH SOME CLEARING
SHOWING UP ALONG THE BLUE RIDGE WHERE LOW LEVEL MOISTURE HAS MIXED
OUT TO SOME DEGREE. HOWEVER GIVEN THE WEAK SUN ANGLE AND LIGHT
WINDS...APPEARS JUST BEFORE MORE WIDESPREAD CLEARING CAN OCCUR WILL
LOSE HEATING CAUSING THE WEDGE TO LIKELY FLOP BACK THIS EVENING.
THIS SHOULD AGAIN CAUSE CLOUDS TO REFORM ESPCLY BLUE RIDGE EAST
WHERE LIGHT EASTERLY FLOW MAY BANK UP THE LOW DECK AGAIN INTO AT
LEAST EARLY TONIGHT. IN ADDITION...SHORTWAVE CROSSING THE WEST MAY
HOLD CLOUDS IN WEST OF THE BLUE RIDGE LONGER THAN USUAL WITH THIS
MOISTURE SCOURING OUT A BIT FASTER LATER THIS EVENING AS THE FLOW
TURNS MORE SW AHEAD OF THE NEXT UPSTREAM COLD FRONT. NAM REMAINS THE
MOST PESSIMISTIC IN HOLDING LOW CLOUDS IN OVERNIGHT AS MOST OTHER
GUIDANCE BREAKS THE WEDGE DOWN AND TURNS TOWARD A PERIOD OF CLEARING
FROM WEST TO EAST BY MORNING. THINK THIS TOO FAST ESPCLY PIEDMONT
WHERE COULD BE EARLY WED BEFORE CLOUDS FINALLY EXIT. WITH ANY
CLEARING...WILL SEE FOG DEVELOP GIVEN WET GROUND AND CHILLY TEMPS
BUT LIKELY ONLY PATCHY EXCEPT PERHAPS A LITTLE MORE WIDESPREAD OUT
EAST LATE. DEWPOINTS SHOULD KEEP LOWS ABOVE FREEZING OUTSIDE THE
DEEPER VALLEYS TONIGHT PENDING DEGREE OF CLEARING...WITH THE RIDGES
LIKELY RISING SOME LATE PER SW FLOW ALOFT. SOME BRIEF PATCHY FROST
POSSIBLE VALLEYS BUT LOOKS RATHER ISOLATED GIVEN MOISTURE IN
PLACE. OTRW WENT A LITTLE BELOW MOS WITH THE WEDGE REDEVELOPING
OVERNIGHT.

5H TROF WILL PASS TO THE NORTH WED ALLOWING AN ASSOCIATED COLD FRONT
TO CROSS THE REGION FROM THE WEST DURING THE AFTERNOON. GIVEN LACK
OF MOISTURE AND DEEP WESTERLY FLOW EXPECT ANY PREFRONTAL BAND OF
SHRA TO FIZZLE CROSSING THE SE WVA MOUNTAINS SO KEEPING MAINLY 20ISH
POPS FAR NW. OTRW TURNING PARTLY SUNNY/BREEZY AND WARMER WITH THE
FRONT ALOFT NOT CROSSING THE BLUE RIDGE UNTIL MID AFTERNOON ALLOWING
HIGHS OUT EAST TO REACH THE LOW/MID 70S. ONSET OF CLOUDS BY
AFTERNOON WESTERN MOUNTAINS...AFTER A CHILLY START...SHOULD KEEP THE
WEST MOSTLY IN THE 60S.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/...
AS OF 310 PM EDT TUESDAY...

HIGH PRESSURE WILL BUILD IN BEHIND THE COLD FRONT ON A 4MB TO 6MB
PRESSURE GRADIENT...RESULTING IN GUSTY NORTHWESTERLY WINDS THROUGH
WEDNESDAY EVENING...WITH A FEW GUSTS IN EXCESS OF 30 MPH ACROSS
THE HIGHER ELEVATIONS. WINDS WILL DIMINISH WEDNESDAY NIGHT INTO
THURSDAY MORNING...AS HIGH PRESSURE SETTLES OVER WEST VIRGINIA.
WITH DRIER COLDER AIR PUSHES IN...LOWS WEDNESDAY NIGHT WILL DROP TO
THE UPPER 20S AND LOWER 30S IN THE COLDEST VALLEYS TO THE LOWER 40S
IN THE SOUTHEAST. ELECTED TO POST A FREEZE WATCH FOR LATE WEDNESDAY
NIGHT INTO THURSDAY MORNING FOR PORTIONS OF SOUTHEAST WEST VIRGINIA
AND BATH COUNTY OF VIRGINIA. FROST IS ALSO POSSIBLE IN THE COLDER
MOUNTAIN VALLEYS IN THE WEST. WILL NEED TO UNPROTECTED VEGETATION
SENSITIVE TO COLDER TEMPERATURES.

HIGH PRESSURE WILL TRAVEL EAST ACROSS THE REGION THURSDAY INTO
THURSDAY NIGHT. PLAYED HIGH TEMPERATURES THURSDAY CLOSE TO THE
ADJMET WITH READINGS FROM THE LOWER 60S IN THE NORTHWEST TO
THE MID 60S IN THE PIEDMONTS. LOW TEMPERATURES THURSDAY NIGHT
WILL VARY FROM THE UPPER 30S IN THE MOUNTAINS TO THE MID 40S IN THE
PIEDMONT.

ON FRIDAY...EXPECT TEMPERATURES TO REMAIN PLEASANT WITH THE
SOUTHWESTERLY FLOW AHEAD OF THE APPROACHING COLD FRONT. THE FRONT
WILL PASS ACROSS THE AREA DURING THE AFTERNOON...WITH ONLY A FEW
SHOWERS IN THE WEST DUE TO THE LACK OF DEEP MOISTURE AHEAD OF THE
BOUNDARY. HIGHS ON FRIDAY WILL RANGE FROM THE LOWER 60S IN THE WEST
TO THE LOWER 70S IN THE SOUTHEAST.

ANOTHER HIGH PRESSURE CENTER WILL BUILD INTO THE AREA BEHIND THE
FRONT...PASSING ACROSS THE GREAT LAKES REGION FRIDAY EVENING ON ITS
WAY TOWARD THE NEW ENGLAND. ACCEPTED THE HPCGUIDEBC LOW TEMPERATURES
FRIDAY NIGHT WITH VALUES FROM THE UPPER 30S IN THE MOUNTAINS TO THE
MID 40S IN THE PIEDMONT.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
AS OF 310 PM EDT TUESDAY...

THE HIGH CENTER WILL MOVE EAST SATURDAY INTO SUNDAY OUT INTO THE
ATLANTIC OCEAN. ANOTHER LOW PRESSURE CENTER CUTS TO OUR WEST AND
TRAILING COLD FRONT WILL APPROACH SUNDAY NIGHT INTO MONDAY. SOUTHWEST
FLOW UNDER THE UPPER RIDGE WILL PUSH MILD AND MOIST AIR INTO OUR
REGION. A COLD FRONT ARRIVES MONDAY INTO MONDAY...FOLLOWED BY DRIER
WEATHER TUESDAY. GENERALLY FOLLOWED HPCGUIDE FOR POPS AND
TEMPERATURES...STARTING BELOW NORMAL AND MODERATING TO NEAR NORMAL
BY TUESDAY.

&&

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
AS OF 200 AM EDT WEDNESDAY...

OVERNIGHT...THE HIGH PRESSURE WEDGE IS STILL HANGING IN THERE
ACROSS OUR AREA...AND APPEARS WE WILL KEEP STRATUS LOCKED IN OVER
LYH AND DAN. FURTHER WEST...SEEING BREAKS IN THE CLOUD COVER...AND
EXPECT IN AND OUT CEILINGS TO PERSIST FOR BCB AND ROA. BLF WILL
LIKELY REMAIN VFR AS THE SOUTHEASTERLY FLOW REMAINS DOWNSLOPE OVER
THE NEARBY TERRAIN. LWB HAS CLEARED OUT...ALLOWING FOG TO
FORM...BUT SHOULD CLOUD COVER REENTER THE AREA...FOG WILL
DISSIPATE.

A COLD FRONT WILL ENTER THE AREA FROM THE WEST DURING LATE MORNING
AND EARLY AFTERNOON. MOISTURE AHEAD OF THE FRONT WILL BE
LIMITED...AND WILL RESULT IN LIGHT SPOTTY SHOWER ACTIVITY MAINLY
ACROSS THE MOUNTAINS. MORE OF AN ISSUE WILL THE BE THE GUSTY
WESTERLY WINDS BEHIND THE FRONT AS HIGH PRESSURE BUILDS IN ON A
4MB TO 5MB PRESSURE GRADIENT. WILL SEE GUSTS APPROACHING 20KTS FOR
MOST AIRPORTS DURING THE AFTERNOON AND EVENING...HOWEVER GUSTS
WILL APPROACH 30KTS AT ROA THANKS TO WIND FUNNELING THROUGH NEARBY
TERRAIN. WIND SPEEDS WILL DIMINISH AFTER SUNSET AS THE GRADIENT
RELAXES AND THE EVENING TEMPERATURE INVERSION SETS UP. MAY SEE IN
AND OUT MVFR CEILINGS DEVELOP BEFORE MIDNIGHT AT BLF AS LOW LEVEL
MOISTURE BECOMES PINNED AGAINST THE NEARBY RIDGELINES TO THE
SOUTHEAST...BUT EXPECT ANY CEILINGS WHICH DEVELOP TO DISSIPATE
EARLY THURSDAY MORNING AS WIND SPEEDS DIMINISH.

HIGH PRESSURE WILL CONTROL THE WEATHER PATTERN THROUGH THE END OF
THE WEEK. ANOTHER COLD FRONT WILL PASS ACROSS THE AREA FRIDAY
NIGHT...BUT IS EXPECTED TO PASS WITH LITTLE TO NO PRECIPITATION
AND A NORTHERLY WIND SHIFT.
