The episode as NWS RNK wrote it up.
Low pressure developed along a cold front across the Tennessee valley and moved across West Virginia and Virginia. A substantial fetch of moisture developed off the Atlantic Ocean and helped to allow showers and thunderstorms that formed to be efficient rain producers. One such cluster of storms moved across the area of Botetourt, Rockbridge and Amherst County region of Virginia. The resultant rainfall caused flash flooding along Back Creek. The flood waters prompted closure of Route 64, Lithia Road.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Mar 10, 12:22 PM EST, 3 hours 8 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
1222 PM EST THU MAR 10 2011
.SYNOPSIS...
COLD FRONT OVER THE EASTERN OHIO AND TENNESSEE VALLEYS WILL MOVE
ACROSS THE APPALACHIAN MOUNTAINS TODAY. A BAND OF SHOWERS AND
THUNDERSTORMS WILL ACCOMPANY THE FRONT...AND SOME OF THIS RAIN
WILL BE LOCALLY HEAVY. COLD NORTHWEST WINDS WILL DEVELOP BEHIND
THE FRONT THIS EVENING WITH ANY LINGERING MOISTURE CHANGING TO
SNOW SHOWERS IN THE MOUNTAINS. CLEARING WILL TAKE PLACE FRIDAY
WITH MAINLY DRY WEATHER SATURDAY. A CLIPPER TYPE SYSTEM WILL MOVE
THROUGH THE GREAT LAKES SATURDAY...ITS ASSOCIATED COLD FRONT
PASSING THROUGH THE MID ATLANTIC REGION SATURDAY NIGHT. ANY
MOISTURE WITH THIS FRONT WILL BE MAINLY CONFINED TO THE MOUNTAINS.
&&
.NEAR TERM /THROUGH TONIGHT/...
A DEVELOPING SURFACE WAVE OVER THE TENN VALLEY WILL TRACK NORTH AND
ALONG THE FRONT THROUGH THIS AFTERNOON. RAIN/DRIZZLE AHEAD OF THE
FRONT WILL GET PUSHED TO THE NORTHEAST WITH CONVECTIVE SHOWERS
MOVING IN ACROSS THE MOUNTAINS EARLY THIS AFTERNOON. THE UPPER LEVEL
TROUGH OVER THE OHIO VALLEY IS EXPECTED TO DEEPEN AND BECOME A
CLOSED LOW LATER THIS AFTERNOON. AS THIS SYSTEM MATURES...LOW LEVEL
FLOW WILL INCREASE MOISTURE TRANSPORT INTO THE REGION. WITH THE AREA
RICH IN MOISTURE AND CONVECTION BECOMES MORE ORGANIZED...HEAVY RAIN
AND DAMAGING WINDS COULD ACCOMPANY STORMS THIS AFTERNOON...ESPECIALLY
IN THE PIEDMONT. VERTICAL SHEAR ALSO FAVORABLE FOR A ISOLATED
TORNADOES TO FORM ACROSS SOUTHSIDE VA. THE LATEST LOCAL MODELS
SUGGESTING SEVERE/HEAVY RAIN THREAT WILL EXIT THE PIEDMONT NO LATER
THAN 700 PM THIS EVENING.
ALSO LATER THIS AFTERNOON/EVENING AND AS THE SURFACE LOW TRACKS
NORTH OF THE AREA...COLD AIR WILL RUSH INTO THE MOUNTAINS. MODELS
INDICATING COLD AIR TO FIRST COME INTO SOUTHWESTERN VIRGINIA
(BLF) THEN SOUTHEASTERN WEST VIRGINA (LWB) AN HOUR OR SO LATER.
TEMPERATURES WILL DROP QUICKLY WITH CRASHING THICKNESSES. RAIN
SHOWERS EXPECT TO TURN OVER TO SNOW SHOWERS PRIOR TO RUSH HOUR
ACROSS THESE TWO REGIONS. ACCUMULATIONS ON ELEVATED SURFACE LIKELY
A COULD CREATE A RUSH HOUR MESS. THE DEFORMATION ZONE WILL REMAIN
OVER THE MOUNTAINS INTO TONIGHT WITH ACCUMULATING SNOW ALONG RNK
WESTERN COUNTIES. SEE WSW FOR MORE DETAILS.
PREVIOUS DISCUSSION...MYRIAD OF WEATHER ISSUES TO DEAL WITH
TODAY. SOUTHEAST WIND IS PRODUCING SOME LOCALLY DENSE FOG ALONG
THE BLUE RIDGE FROM FLOYD/PATRICK SOUTHWEST INTO THE NC
MTNS...INCLUDING I-77 BETWEEN MM4 AND MM7. FLOOD WATCH CONTINUES
FOR THE ENTIRE CWA...BUT NOW FOCUSING ON BAND OF HEAVY RAIN TO BE
ASSOCIATED WITH THE FRONTAL PASSAGE. SEVERE WEATHER THREAT EXISTS
OVER SOUTHSIDE VA AND THE PIEDMONT OF NC WHERE THUNDERSTORMS ARE
EXPECTED TO DEVELOP ALONG THE FRONT AS IT TAPS THE DEEPER MOISTURE
EAST OF THE BLUE RIDGE THIS AFTERNOON. AND...AN ACCUMULATING SNOW
IS EXPECTED IN THE MOUNTAINS OF WV...FAR WRN VA...AND NC WHERE THE
RAIN WILL CHANGE TO SNOW THIS AFTERNOON AND CONTINUE THROUGH THE
OVERNIGHT TONIGHT.
VIGOROUS UPPER LEVEL TROF IS PROGGED TO CROSS THE FCST AREA
TODAY...A WAVE OF LOW PRESSURE DEVELOPING OVERHEAD AS THE FRONT
CROSSES THE CWA. THE FRONT IS FCST TO REACH BLUEFIELD AND BOONE
BETWEEN 11AM AND 2PM TODAY...THEN PASS EAST OF THE MTNS INTO THE
ERN CWA BETWEEN 2PM-5PM. DO NOT THINK WE ARE OUT OF THE WOODS JUST
YET FOR HEAVY RAINFALL AND POTENTIAL FLOODING PER THINKING THAT
BAND OF SHRA/TSRA WILL STRENGTHEN AS THE FRONT TAPS THE HIGHER
DEWPOINT AIRMASS EAST OF THE MTNS. POTENTIAL EXISTS FOR THE FRONT
TO ALSO SLOW DOWN AS A WAVE OF LOW PRESSURE DEVELOPS ALONG THE
FRONT...RESULTING IN TRAINING OF HEAVY SHOWERS OVER THE ERN CWA
THIS AFTERNOON. ADDITIONAL CAVEAT WILL BE THE A SEVERE WEATHER
THREAT. HIGH SHEARED ENVIRONMENT...CAPES INCREASING TO NEAR 500
OVER THE PIEDMONT...AND VIGOROUS LIFT ASSOCIATED WITH THE UPPER
TROF WILL PROMOTE DEVELOPMENT OF THUNDERSTORMS ALONG THE FRONTAL
BOUNDARY. THIS SEVERE THREAT WILL PRIMARILY BE BETWEEN 2-5PM...OR
UNTIL THE FRONT EXITS THE CWA.
CRASHING THICKNESSES ON THE BACK SIDE OF THE FRONT THIS AFTERNOON
WILL RESULT IN RAPID CHANGE OVER FROM RAIN-SNOW IN THE MTNS OF
WV...THE MOUNTAIN EMPIRE OF VA...AND THE NC MTNS. DEFORMATION ZONE
ON THE BACK SIDE OF THE UPPER TROF IS PROGGED TO LINGER OVER THE
MOUNTAINS THROUGH TONIGHT AND WITH 85H TEMPS DROPPING TO NEAR M8
DEG C...SURFACE TEMPS WILL PLUMMET INTO THE UPPER 20S. AS
SUCH...SNOW WILL EASILY ACCUMULATE WITH AMOUNTS OF 1-2 INCHES IN
THE VALLEYS TO AS MUCH AS 5 INCHES IN THE HIGHER ELEVATIONS.
WINTER WEATHER ADVISORIES HAVE BEEN POSTED.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
ACTIVE WEATHER CONTINUES THROUGH THE SHORT TERM PERIOD. FOR
FRIDAY...UPSLOPE SNOW MACHINE CONTINUES ALONG THE WESTERN
SLOPES...BUT DIMINISHING THROUGH THE DAY AS MOISTURE DEPTH BECOMES
MORE SHALLOW WITH RIDGING BUILDING IN. BIGGEST CHANGE TO THE
FORECAST WAS TO RAMP UP WINDS WITH BUFKIT FORECAST SOUNDINGS
INDICATING GOOD MOMENTUM TRANSFER OF STRONG LOW LEVEL WINDS. A FEW
SPOTS ALONG THE HIGHER RIDGES WILL LIKELY EXCEED WIND ADVISORY
LEVELS. OTHERWISE...LOWERED TEMPS IN THE MOUNTAINS WITH STRONG CAA.
MODELS AGREE WEAK SFC SHORTWAVE RIDGE WILL COVER THE FORECAST AREA
FRIDAY NIGHT...BUT WITH 850MB WINDS STILL PROJECTED TO BE 30-40KTS
TRIED TO SHOW A VALLEY/RIDGE SPLIT IN LOW TEMPS WITH COOLER THAN
GUIDANCE VALUES FORECAST IN THE VALLEYS AND ABV GUIDANCE IN ALONG
THE RIDGES.
THE NEXT SYSTEM TO MONITOR IS ANOTHER NORTHERN STREAM SYSTEM THAT
THE NAM AND GFS STRENGTHEN AND PUSH INTO THE EASTERN OHIO VALLEY BY
SATURDAY EVENING. HOWEVER...THE ECMWF FORECASTING ONLY A WEAK OPEN
WAVE THROUGH WITH NO PRECIP. FOR NOW...CONTINUED FORECAST
CONSISTENCY WITH SMALL POPS ALONG THE WESTERN SLOPES OF SE WV LATE
SATURDAY AND SATURDAY NIGHT.
WITH A DEEP WEST FLOW BACKING SOME IN THE LOWER LEVELS...APPEARS A
GOOD DOWNSLOPING EVENT WILL TAKE PLACE WHICH SHOULD PUSH TEMPS
TOWARD THE MUCH WARMER GFS MOS GUIDANCE. ALSO INCREASED WINDS ON
SATURDAY WITH EVEN THE WEAKEST ECMWF BRINGING A 35KT 850MB WESTERLY
WIND.
LIGHT UPSLOPE PRECIP LINGERS SATURDAY NIGHT WITH THE 03Z SREF
INDICATING A SMALL CHANCE OF MEASURABLE SNOW IN WESTERN GREENBRIER
COUNTY.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
AFTER THE FRONTAL PASSAGE SATURDAY NIGHT...TEMPERATURES WILL FALL
INTO THE LOWER 30S EARLY SUNDAY MORNING ACROSS SOUTHEAST WEST
VIRGINIA...PARTICULARLY GREENBRIER COUNTY... CAUSING RAINFALL TO
CHANGE OVER TO SNOW FOR A FEW HOURS AROUND SUNRISE.
MONDAY BRINGS A CHILLY AND WET WEATHER PATTERN ACROSS OUR AREA AS
HIGH PRESSURE BUILDS IN FROM UPPER NEW ENGLAND DOWN THE EAST SIDE
OF THE APPALACHIANS...WHILE ANOTHER LOW PRESSURE SYSTEM MOVES
EASTWARD ACROSS THE SOUTHEAST STATES. THIS SYSTEM WILL SEND GULF
MOISTURE NORTHWARD INTO OUR REGION...WITH SHOWERS DEVELOPING IN
THE COOL AIR WEDGED AGAINST THE HIGHER RIDGE LINES IN THE WESTERN
EDGE OF OUR REGION. AS THIS LOW PRESSURE SYSTEM REMAINS WELL TO
OUR SOUTH... MOISTURE FLOW INTO OUR REGION WILL REMAIN
LIMITED...AND AT THIS TIME WILL BE EXPECTING LESS THAN A HALF INCH
OF PRECIPITATION WITH THIS SYSTEM. SNOW WILL AGAIN BE POSSIBLE
EARLY TUESDAY MORNING ACROSS SOUTHEAST WEST VIRGINIA AND THE
ALLEGHANY HIGHLANDS OF VIRGINIA AS LOW TEMPERATURES ACROSS THOSE
AREAS APPROACH THE FREEZING MARK.
AS THIS SYSTEM PUSHES OFF SHORE ON TUESDAY EVENING...PRECIPITATION
WILL COME TO AN END ACROSS OUR AREA...LEAVING HIGH PRESSURE TO OUR
EAST AS THE DOMINATING WEATHER FEATURE. TEMPERATURES WILL REBOUND
WEDNESDAY AS CLOUDS DECREASE DURING THE MORNING...AND AS WINDS
BECOME MORE SOUTHERLY...BRINGING WARMER AIR INTO OUR AREA.
&&
.AVIATION /17Z THURSDAY THROUGH MONDAY/...
WIDESPREAD IFR CONDITIONS WILL CONTINUE UNTIL PASSAGE OF COLD
FRONT LATER THIS AFTERNOON. 40 KT LLJ AHEAD OF THE FRONT WILL ALSO
RESULT IN SOME LOW LEVEL WIND SHEAR UNTIL FROPA.
THE COLD FRONT WILL ARRIVE BY MID AFTERNOON...MOVING THROUGH BLF/LWB
BETWEEN 1PM AND 3PM...AND THEN THROUGH ROA/LYH/DAN BETWEEN 4PM
AND 7PM. PERIOD OF HEAVY RAIN WITH EMBEDDED THUNDERSTORMS WILL
OCCUR FOR SEVERAL HOURS PRIOR AND ACCOMPANY THE FRONTAL PASSAGE.
POTENTIAL FOR SEVERE STORMS EXIST AFTER 2PM EAST OF A LYH-DAN
LINE...THE THREAT ENDING WITH THE FRONTAL PASSAGE.
WINDS WILL SHIFT FROM SOUTHERLY TO WESTERLY WITH THE FRONTAL
PASSAGE. GUSTY WEST TO NORTHWEST WINDS WILL THEN PERSIST TONIGHT
AND INTO THE DAY FRIDAY. AN ACCUMULATING MOUNTAIN SNOW IS LIKELY
TONIGHT DUE TO LINGERING MOISTURE IN THE MOUNTAINS. THIS WILL
LIKELY IMPACT BLF AND LWB. THE SNOW MAY BE MODERATE TO HEAVY AT
TIMES.
THE MOUNTAIN SNOW WILL GRADUALLY TAPER TO FLURRIES FRIDAY WITH
CLEARING TAKING PLACE EAST OF THE MOUNTAINS. VFR IS EXPECTED AT
ALL TAF SITES FRIDAY NIGHT INTO SATURDAY. ANOTHER FRONTAL PASSAGE
MAY BRING MVFR CONDS AND PRECIPITATION TO THE MOUNTAINS SAT NIGHT
INTO SUNDAY...WITH LITTLE OR NO RESTRICTIONS EAST OF THE BLUE RIDGE.
&&
.HYDROLOGY...
RAIN AMOUNTS THUS FAR HAVE RANGED FROM ABOUT A HALF INCH TO AS
MUCH AS 2.00 INCHES...BUT EVEN THE HEAVY AMOUNTS HAVE OCCURRED
OVER A LONG DURATION ALLOWING FOR A MODEST RUNOFF.
FOR TODAY...CONCERN IS FOR TRAINING OF HEAVY SHOWERS AND POTENTIAL
THUNDERSTORMS ASSOCIATED WITH A FRONTAL PASSAGE AROUND MID-
DAY. UNTIL THE FRONT CROSSES THE AREA...WILL MAINTAIN THE FLOOD
WATCH. STILL NOT OUT OF THE QUESTION TO GENERATE ANOTHER HALF INCH
TO AS MUCH AS 2.00 INCHES PENDING DEVELOPMENT OF THESE FRONTAL SHOWERS.
FLOOD WARNINGS WILL CONTINUE FOR THE LOWER ROANOKE RIVER AT
RANDOLPH AND THE DAN RIVER FROM DANVILLE DOWNSTREAM TO SOUTH
BOSTON...AND FOR THE JAMES RIVER. QUIDANCE SUGGESTS THAT FLOODING
WILL NOT BE AS SEVERE AS ORIGIALLY FORECAST...BUT UNTIL WE SEE
JUST HOW MUCH RAIN WE GET FROM THE FRONTAL SHOWERS/THUDERSTORMS
THIS AFTERNOON...HESITANT TO CANCEL ANY OF THE WARNINGS.
