The episode as NWS RNK wrote it up.
An area of low pressure strengthened as it moved north of our area. Behind the cold front associated with this low, gusty northwest winds developed which blew down trees and power lines across portions of the northwest North Carolina mountains.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
352 PM EST WED DEC 7 2011
.SYNOPSIS...
VIGOROUS UPPER LEVEL LOW WILL MOVE ACROSS THE MID ATLANTIC REGION
TONIGHT WITH CYCLOGENESIS TAKING PLACE OVER EASTERN VIRGINIA...AND
THE RESULTANT CYCLONE MOVING RAPIDLY NORTHEAST ALONG THE NEW ENGLAND
COAST. HIGH PRESSURE WILL BUILD ACROSS THE AREA FOR THURSDAY...
BRINGING A TRANSITION TO FAIR DRY WEATHER FOR FRIDAY AND THE
UPCOMING WEEKEND.
&&
.NEAR TERM /THROUGH TONIGHT/...
AS OF 330 PM EST WEDNESDAY...
MYRIAD OF WEATHER ISSUES TO WORK THROUGH THIS EVENING...TO INCLUDE
EXCESSIVE RAIN...P-TYPE CHANGE...AND HIGH WINDS.
ROBUST UPPER LOW OVERHEAD THIS EVENING TO PROVIDE LIFT FOR SURFACE
CYCLOGENESIS ALONG FRONTAL BOUNDARY WHICH IS MOVING EAST ACROSS THE
VA/NC PIEDMONT. THIS SURFACE LOW IS EXPECTED TO RAPIDLY MOVE
NORTHEAST AND DEEPEN TO A 992 MB LOW NR LONG ISLAND BY
MIDNIGHT...AND 980 MB BY DAYBREAK THURSDAY AS IT PASSES EAST OF
MACHIAS MAINE.
WE ARE NOW WITHIN THE FINAL STAGES OF PRECIP PRODUCTION FOR OUR
CWA...ANY REMAINING QPF CONFINED TO JUST THIS EVENING. RAINFALL
TOTALS FOR THE EVENT WILL LIKELY BE IN THE 1 TO 3 INCH RANGE WITH
SOME LOCALLY HIGHER AMOUNTS...AROUND 4 INCHES...NEAR THE BLUE RIDGE.
THIS WILL RESULT IN SUBSTANTIAL RISES ALONG AREA STEAMS AND CREES
WITH CONTINUED POTENTIAL FOR PONDING OF WATER AND LOWLAND FLOODING
ISSUES. IT WILL ALSO TAKE A DAY OR TWO FOR THE WATER TO DRAIN
THROUGH THE RIVER NETWORK WITH SIGNIFICANT RISES ANTICIPATED
TOO...SEE HYDRO SECTION OF THIS DISCUSSION FOR DETAILS.
THERE MAY BE A BRIEF PERIOD THIS EVENING...BEFORE 7 PM...WHERE
POTENTIAL FOR ISOLATED SEVERE STORM MAY TAKE PLACE BEFORE THE FRONT
CLEARS OUR FAR EASTERN CWA. STORM RELATIVE HELICITIES ARE HIGH BUT
CAPE SEEMS PRETTY ANEMIC...LESS THAN 500 J/KG. A MORE FAVORABLE
ENVIRONMENT FOR SEVERE STORMS EXISTS OVER THE TIDEWATER OF VA/NC
WHERE SOME SOLAR INSOLATION TOOK PLACE DURING THE AFTERNOON.
P-TYPE CHANGE OF THE PRECIP IS UNDERWAY ACROSS THE WESTERN CWA. LOOK
FOR RAPID CHANGE OVER TO SNOW THIS EVENING AS COLDER AIR WORKS ITS
WAY INTO THE BACK SIDE OF THE STORM SYSTEM. SEVERAL HOURS OF SNOW IS
POSSIBLE WEST OF THE BLUE RIDGE THIS EVENING B4 THE PRECIPITATION
COMES TO AN END. ALSO BE ON THE LOOKOUT FOR BLACK ICE AS
TEMPERATURES FALL INTO THE 20S CAUSING WATER TO FREEZE...ESP ON
BRIDGES AND OVERPASSES. WINTER WEATHER ADVISORIES ARE IN EFFECT FROM
THE NC MTNS NORTHEASTWARD INTO THE VA HIGHLANDS AND WV MTNS. 1 TO 4
INCHES OF SNOW IS POSSIBLE WITHIN THIS CORRIDOR...THE HIGHER AMOUNTS
OCCURRING AT THE HIGHER ELEVATIONS...SEE WINTER WEATHER ADVISORY
STATEMENT FOR DETAILS. TEMPERATURES WILL BE COOLING FROM TOP
DOWN...THE VALLEYS THE LAST TO EXPERIENCE THE CRITICAL TEMPERATURES.
THE GROUND IS WARM AND WET...THUS THE FIRST HOUR OR TWO OF SNOW
PRODUCTION SHOULD MELT ON CONTACT. THE ONLY THING THAT MAY COUNTER
THIS WOULD BE FOR SNOW RATES TO INCREASE...TO AN INCH AN HOUR OR
MORE...WHICH IS A DISTINCT POSSIBILITY AS SUPPORT FROM THE UPPER LOW
PASSES OVERHEAD THIS EVENING. DURATION OF THE SNOW LOOKS LIKE IT
WILL BE LIMITED TO JUST THE EVENING HOURS...B4 MIDNIGHT...THUS IT
WILL BE A RACE TO SEE HOW FAST WE CAN COOL THE BOUNDARY LAYER AND
ACCUMULATE SNOW B4 THE PRECIP COMES TO AN END. ALL THINGS
CONSIDERED...THIS JUSTIFIES NEED FOR LARGE SPREAD IN OUR SNOW FALL
PAINT BRUSH.
LOOKING BEYOND THE SCOPE OF THE PRECIP ISSUES...THE WAKE PRESSURE
RISES...WHICH MAY EXCEED 12 MB BETWEEN 6PM AND MIDNIGHT THIS
EVENING...RAISE CONCERN FOR HIGH WINDS. STRONG CROSS BARRIER FLOW IS
EXPECTED TO DEVELOP THIS EVENING WITHIN THE WAKE OF THE DEPARTING
STORM SYSTEM. FORECAST SOUNDINGS...ESPECIALLY THOSE ALONG THE BLUE
RIDGE...SUGGEST BOUNDARY LAYER WIND GUSTS OF NEAR 50 KTS ARE
POSSIBLE. WITH THE WET GROUND...TREES WILL BE MUCH EASIER TO UPROOT.
AS SUCH HAVE ISSUED A WIND ADVISORY ALONG THE BLUE RIDGE INCLUDING
THE VA HIGHLANDS...NEW RIVER...ROANOKE AND SOUTHERN SHENANDOAH
VALLEYS...FOR WIND GUSTS OF 40 TO 55 MPH. A HIGH WIND WARNING HAS
BEEN ISSUED FOR THE HIGH COUNTRY OF NC AND INTO SW VA TO INCLUDE
GRAYSON...CARROLL...AND FLOYD. WIND GUSTS OF UP TO 60 MPH WILL
FAVOR THESE AREAS.
AFTER WE GET PAST TONIGHT...THE WEATHER BECOMES QUIET QUICKLY. THE
CYCLONE SHOULD BE FAR ENOUGH REMOVED FROM THE CWA NOT TO BE A PLAYER
DURING THE DAY THURSDAY. HIGH PRESSURE WILL REPLACE THIS SYSTEM AND
BECOME SITUATION OVERHEAD...WINDS ALSO DIMINISHING QUICKLY.
LOOKING FORWARD TO A LITTLE SUN.
&&
.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
...AS OF 330 PM EST WEDNESDAY...
EXPECT THAT WE WILL FIND OUT THE DIFFERENCE BETWEEN A PACIFIC HIGH
PRESSURE SYSTEM AND A POLAR HIGH PRESSURE SYSTEM COME FRIDAY...AS WE
WILL SEE BOTH TYPES PASS THROUGH OUR REGION. WE START OFF FIRST WITH
THE PACIFIC HIGH PRESSURE SYSTEM WELL ESTABLISHED OVER OUR AREA ON
THURSDAY NIGHT. WE CAN EXPECT RELATIVELY CLEAR SKIES ACROSS OUR
AREA...PERHAPS A LITTLE CLOUD COVER IN THE MOUNTAINS LEFT OVER FROM
THE DEPARTING STORM SYSTEM. TEMPERATURES THURSDAY NIGHT AND FRIDAY
WILL BE VERY CLOSE TO NORMAL FOR THIS TIME OF YEAR...WITH EARLY
FRIDAY MORNING LOWS IN THE UPPER 20S TO NEAR 30...AND FRIDAY
AFTERNOON HIGHS IN THE MID 40S WEST OF THE BLUE RIDGE...AND IN THE
UPPER 40S TO LOW 50S TO THE EAST.
BY FRIDAY EVENING...AN ALBERTA CLIPPER STYLE COLD FRONT WILL MAKE
ITS WAY THROUGH OUR REGION...USHERING IN THE POLAR HIGH PRESSURE.
ACROSS MUCH OF OUR AREA...THE FRONTAL PASSAGE WILL BE MARKED MAINLY
BY A DROP IN TEMPERATURES AND A NORTHWESTERLY WIND SHIFT...WITH
GUSTS UP TO 25 MPH WEST OF THE BLUE RIDGE. HOWEVER...AREAS FROM THE
NORTH CAROLINA MOUNTAINS TO THE ALLEGHANY HIGHLANDS WILL SEE SNOW
SHOWERS DEVELOP FRIDAY NIGHT AND EARLY SATURDAY MORNING. MOISTURE IS
PRETTY LIMITED AHEAD OF THE CLIPPER FRONT...AND DO NOT EXPECT TO SEE
MORE THAN A QUARTER INCH OF NEW SNOW ACCUMULATIONS AS SNOWFALL IS
EXPECTED TO END BY LATE SATURDAY MORNING.
WITH POLAR HIGH PRESSURE BECOMING ESTABLISHED OVER THE WEEKEND...
AFTERNOON TEMPERATURES FROM THE ALLEGHANY HIGHLANDS THROUGH THE
NORTH CAROLINA MOUNTAINS WILL STRUGGLE TO RISE INTO THE MID 30S.
WINDS WILL REMAIN ON THE GUSTY SIDE DURING THE AFTERNOON...BUT WILL
BEGIN TO DIMINISH AROUND SUNSET AS THE PRESSURE GRADIENT RELAXES.
WITH CLEAR SKIES ACROSS OUR REGION...SATURDAY NIGHT TEMPERATURES
WILL BE SOME OF THE CHILLIEST OF THIS SEASON...WITH LOWS RANGING
FROM THE MIDDLE TEENS IN SOUTHEAST WEST VIRGINIA...TO THE LOW 20S
ACROSS PARTS OF THE PIEDMONT REGION.
&&
.LONG TERM /SUNDAY THROUGH NEXT WEDNESDAY/...
...AS OF 330 PM EST WEDNESDAY...
HIGH PRESSURE MAINTAINS ITS CONTROL OF OUR WEATHER PATTERN ON
SUNDAY...AS THE HIGH REMAINS WEDGED ALONG THE EASTERN SLOPES OF THE
APPALACHIANS. LONG RANGE FORECAST MODELS ARE IN AGREEMENT THAT A
DEEP LOW PRESSURE SYSTEM WILL DEVELOP OVER THE ATLANTIC EARLY NEXT
WEEK...BUT THAT THIS SYSTEM WILL REMAIN SUFFICIENTLY FAR TO THE EAST
THAT IT WILL NOT SIGNIFICANTLY IMPACT OUR REGION. TEMPERATURES ARE
EXPECTED TO WARM ACROSS OUR REGION AGAIN ON TUESDAY...AS WINDS
BECOME MORE SOUTHERLY AHEAD OF OUR NEXT COLD FRONT. AS THE COLD
FRONT PASSES THROUGH OUR AREA...EXPECT THAT WE WILL SEE A MIXTURE OF
RAIN AT LOWER ELEVATIONS...AND SNOW ALONG OUR WESTERN RIDGELINES.
&&
.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
AS OF 1225 PM EST WEDNESDAY...
IFR TO LIFR CONDITIONS WILL CONTINUE THROUGHOUT THE FORECAST AREA
THROUGH LATE THIS AFTERNOON...WITH SOME BREAKS POSSIBLE AT TIMES
ESPECIALLY DAN/LYH AHEAD OF THE FRONT BETWEEN 18Z-22Z/1P-5P WED. LOW
PRESSURE DEVELOPING IN NORTH CAROLINA ALONG A COLD FRONT WILL LEAD
TO RAPIDLY CHANGING CONDITIONS INTO THIS EVENING. MUCH COLDER AIR
WILL COME INTO THE MOUNTAINS...CHANGING THE PRECIPITATION TO SNOW.
AS THE LOW MOVES NORTHEAST AND SURFACE/LOW LEVEL WINDS COME AROUND
TO THE NORTHWEST...CONDITIONS WILL IMPROVE EAST OF THE BLUE RIDGE.
WINDS WILL INCREASE WITH GUSTS TO 35 KNOTS POSSIBLE AFTER 00Z/7P.
GUSTS UP TO 40-45 KNOTS ARE POSSIBLE IN THE CORRIDOR ALONG THE BLUE
RIDGE BETWEEN ROA-GEV-TNB. SHOULD SEE IMPROVING CIGS LATE THIS
EVENING IN THE EAST AND CLEARING OUT IN THE WEST AFTER MIDNIGHT.
A RETURN TO VFR AND DIMINISHING WINDS ARE EXPECTED BY THURSDAY
AFTERNOON AND FRIDAY AS HIGH PRESSURE MOVES INTO THE AREA. ON
SATURDAY...SOUTHEAST WEST VIRGINIA MAY SEE SOME MVFR CONDITIONS AS
A CLIPPER SYSTEM MOVES THROUGH THE AREA.
&&
.HYDROLOGY...
AFTER WIDESPREAD 1-3 INCHES FELL ACROSS THE BASINS FROM THE BLUE
RIDGE WESTWARD ENDING AT 12Z THIS MORNING WE HAVE SEEN AN ADDITIONAL
0.25 TO 0.50 INCHES OF BASIN-AVERAGE RAINFALL FROM 12Z TO 18Z IN
THE GREENBRIER...FAR UPPER JAMES...UPPER ROANOKE...MIDDLE NEW AND
TENNESSEE BASINS. POINT RAINFALL AMOUNTS UP TO A MAXIMUM AROUND 1
INCH OR SLIGHTLY HIGHER HAVE BEEN OBSERVED IN THIS SAME 6-HOUR
PERIOD. BASINS EAST OF THE BLUE RIDGE AMOUNTS HAVE SEEN MUCH LESS
RAIN AGAIN TODAY AND NO REAL HYDROLOGIC ISSUES IN THAT AREA.
12Z GUIDANCE WAS INDICATING THAT FLOOD STAGE WOULD BE REACHED AT
BOTH THE GREENBRIER RIVER AT ALDERSON AND ON THE JAMES RIVER DOWN AT
BREMO BLUFF. RIVER MODEL WAS RERUN WITH 18Z DATA AND 30-40 PERCENT
LOWER QPF IN THE 18Z-00Z TIME FRAME WILL BRING ALDERSON IN BELOW
FLOOD STAGE..NOW EXPECTED TO STAY 1-2 FEET BELOW. UPDATED RIVER
FORECAST THE JAMES ALSO LOOKING TO COME IN BELOW FLOOD STAGE AT ALL
POINTS BUT MAY EXCEED ACTION STAGE AT SEVERAL LOCATIONS. EARLIER
GUIDANCE SHOWING BREMO BLUFF REACHING FLOOD STAGE REVISED DOWNWARD
AND NOW EXPECT CREST ABOVE ACTION BUT BELOW FLOOD STAGE ON FRIDAY.
FLOOD WATCH FOR THE NORTHERN HALF WILL REMAIN IN EFFECT UNTIL 7 PM
AS THE STEADY LIGHT TO MODERATE RAINFALL THE REST OF THE DAY AND
INTO THIS EVENING MAY CAUSE SOME LOCAL RUNOFF AND MINOR PROBLEMS IN
AREAS WHERE WATER NORMALLY PONDS IN LOW-LYING AREAS. GREENBRIER
COUNTY HAS SEEN THIS HEAVIEST RAIN AND MAY BE MOST LIKELY TO
EXPERIENCE THIS TYPE OF MINOR FLOODING. MANY SMALLER STREAMS AND
RIVERS WILL BE RISING RAPIDLY AND MAY BE AT OR NEAR BANKFULL BUT
SIGNIFICANT SMALL STREAM FLOODING IS NOT ANTICIPATED OVERNIGHT AS THE
COLD AIR RUSHES IN AND CONVERTS RAIN TO SNOW IN THE WEST WHICH WILL
SLOW RUNOFF.
IN ADDITION STRONGER CELLS NOW DEVELOPING AHEAD OF THE BOUNDARY EAST
OF THE BLUE RIDGE ARE RACING NORTHWARD INTO SURRY AND PATRICK
COUNTIES AND WILL PRODUCE BRIEF HEAVY DOWNPOURS WITH RATES IN EXCESS
OF 1 INCH PER HOUR AND SOME PONDING OF WATER ON ROADS WILL OCCUR.
COULD BE A FLASH FLOOD ISSUE IF IT PERSISTS FOR VERY LONG.
