The episode as NWS RNK wrote it up.
A storm system moved into the Ohio Valley, spreading gulf moisture into the area, while high pressure over New England provided cold air. Mixed precipitation fell across southwest Virginia, but amounts were light. However, colder air over Bath county, kept the precipitation as snow, and up to 6 inches fell across the county, especially the western sections.

NWS Blacksburg, VA wrote its last area forecast discussion before the first event at Feb 24, 9:26 PM EST, 1 hour 34 minutes earlier.

.UPDATE...

.SHORT TERM /REST OF TONIGHT/...
WATCHING THE WARM ADVECTION PRECIP SPREADING NORTHEAST AND MAKING
SLOW HEADWAY INTO THE VERY DRY AIRMASS OVER THE FORECAST AREA.
NEVERTHELESS...SOME IS MANAGING TO REACH THE GROUND NOW...AND IS A
MIXTURE OF RAIN AND SLEET. 18Z MODELS SHOW THE BEST BAROCLINIC ZONE
AND ISENTROPIC LIFT SETS UP ACROSS THE GREENBRIER VALLEY OF SE WV
AND INTO THE HIGHLANDS OF VA WHERE WE HAVE THE WINTER STORM
WARNING GOING RIGHT NOW. THE FORECAST IS ON TRACK STILL...WITH THE
IDEA THAT THE RAIN AND SLEET WILL TRANSITION TO RAIN WITH POCKETS
OR AREAS OF FREEZING RAIN AS THE SURFACE TEMPERATURE LOWERS TO AT
OR A FEW DEGREES BELOW FREEZING. THIS WILL BE ALL IN-SITU TYPE
DAMMING. I SAW NO REASON AT THIS POINT TO ADJUST THE WARNINGS AND
ADVISORIES THAT WE HAD GOING. 18Z MODELS CAME IN A LITTLE WARMER
LOOKING AT MODEL SOUNDINGS...BUT WITH SUCH LOW DEWPOINTS AND A DRY
AIRMASS I/M NOT READY TO TRIM DOWN THE AREA THAT MAY SEE FREEZING
RAIN AT THIS POINT- BEST TO WAIT UNTIL THE PRECIP DEVELOPS AND
ADJUST ON THE FLY. AT LEAST IT DOES NOT LOOK LIKE THERE WILL BE
ANY SIGNIFICANT FREEZING RAIN OUTSIDE OF OUR WARNING AND ADVISORY
AREAS. IN ADDITION GROUND AND ROAD TEMPS SHOULD BE QUITE WARM...SO
THERE IS EVEN LESS OF A THREAT FOR ROADS TO BECOME ICY- MOST ICING
SHOULD BE IN THE TREES/ELEVATED SURFACES. FINALLY...I KEPT THE
WIND ADVISORY/HIGH WIND WARNING GOING AS WELL. 18Z MODELS STILL
SHOW A STRONG SOUTH-SOUTHEAST LLJ OF 60+ KNOTS LATE TONIGHT INTO
SUNDAY AND THERE IS A GOOD CHANCE THIS WILL MIX TO THE SFC ON THE
RIDGE TOPS AND NORTH SIDE OF RIDGES. THE ONLY CHANGE WITH THAT WAS
TO PUSH THE TIMING TO A LITTLE LATER TONIGHT- CLOSER TO 400 AM
WHEN THE STRONG GUSTS REACH THE SURFACE.

/ISSUED 653 PM EST SAT FEB 24 2007/
AVIATION /00Z-24Z/...
VFR CONDITIONS CAN BE EXPECTED THROUGH MOST OF THE NIGHT AS DRY
AIR HANGS ON A LITTLE LONGER. MOISTURE WILL FINALLY TRANSITION
TOWARD THE GROUND WITH CIGS LOWERING AND PRECIP FALLING. AT THE
AIRPORTS MAINLY RAIN WILL OCCUR FOR THIS EVENT. EXCEPTIONS WILL BE
LWB FROM 04Z-19Z...WITH A TRANSITION OF SNOW/SLEET EARLY BECOMING
FZRA BY DAWN. CONDITIONS WILL DROP TO IFR ON OCCASION THERE. LYH
WILL ALSO A BRIEF PERIOD OF FZRA FROM 13-17Z. OVERALL...EXPECT IFR
AT ALL SITES FOR MOST OF SUNDAY...TO OCCASIONAL LIFR.
PREV DISCUSSION...
/ISSUED 251 PM EST SAT FEB 24 2007/
SHORT TERM /TONIGHT THROUGH SUNDAY NIGHT/...
WEATHER SCENARIO OVER THE NEXT 36 HOURS REMAINS QUITE COMPLICATED AS
EAST COAST RIDGE QUICKLY GIVES WAY TO INCREASING MOISTURE AHEAD OF
MIDWEST S/W TROF AND WARM ADVECTION PATTERN. AS RIDGE SPLITS THIS
EVENING...WARM FRONT OVER THE MISS VALLEY WILL BEGIN TO LIFT NORTH
WITH ISENTROPIC PATTERN DEVELOPING OVERNIGHT AS BOUNDARY ATTEMPTS TO
PUSH INTO DRY AIR OVER THE REGION. MODELS REMAIN DIFFERENT ON AMOUNT
OF PRECIP AND TIMING OF QPF...WITH THE GFS MUCH FASTER TO BRING
PRECIP IN ESPCLY NW THIS EVENING WHILE THE OTHER GUIDANCE LAGGING
TIL AFTER MIDNIGHT. CURRENT TRENDS WOULD SUGGEST THE GFS BETTER BUT
GIVEN BONE DRY DEWPOINTS EXPECT A BIT TOO FAST. REMAINDER OF LIFT
ASSOCIATED WITH WEAK FRONT AND UPPER DIFFLUENCE WILL ARRIVE SUNDAY
MORNING AND THEN EXIT DURING THE AFTERNOON. MODELS INDICATING A
STORM TOTAL RANGE FROM A THIRD OF AN INCH TO AS MUCH AS AN INCH WITH
THE SYSTEM. HOWEVER SOME CONCERN OVER MOST SIG PRECIP PASSING TO THE
NW TONIGHT AND THEN BEST COVERAGE SOUTH SUNDAY CLOSER TO RESIDUAL
WARM FRONT/INSTABILITY GRADIENT.
OTRW MAIN ISSUE WITH PTYPE AND HOW MUCH BELOW FREEZING TEMPS MIGHT
FALL GIVEN SITUATION WHERE PRECIP HAS TO COOL THE COLUMN
OVERNIGHT...UNLESS SOME BREAKS DEVELOP THIS EVENING...AND STRONG
WARM ADVECTION PROCESSES DEVELOP ALOFT OVERTOP INSITU WEDGE. FORCAST
TEMPS SUGGEST THAT PRECIP MIGHT NOT BE HEAVY ENOUGH TO PUSH TEMPS
BELOW FREEZING NORTH UNTIL LATE OR SUNDAY MORNING AND THEN COULD
EDGE INTO THE 30S EXCEPT DEEP VALLEYS SUNDAY. HOWEVER RAOBS SUPPORT
A GOOD AMOUNT OF FZRA ESPCLY ELEVATED SURFACES FAR NORTHERN ZONES IF
QPF COMES TRUE WHEN BELOW FREEZING. THUS PLAN TO UPGRADE MOST OF THE
WATCH AREA TO A WINTER STORM WARNING WITH EMPHASIS MORE ON VALLEY
ICING...WITH SOME SLEET MIXED IN AS WELL ALTHOUGH CONFIDENCE IS
QUITE LOW GIVEN CURRENT WARMING TODAY AND LACK OF COLD RIDGING. LOW
LEVEL EASTERLY FLOW MAY BE ENOUGH TO AID COOLING BLUE RIDGE SO
LEAVING ADVISORY IN PLACE FOR NOW. OTHER ISSUE WITH STRONG SOUTHERLY
WINDS IN THE FAR WEST WHERE 85H 50-60 KT JET MAY BE ABLE TO MIX DOWN
TO THE RIDGETOPS DESPITE QUITE A HIGH LEVEL INVERSION TO OVERCOME.
TYPICAL SCENARIO FOR TAZEWELL CTY TO SEE HIGH WIND WARNING CRITERIA
SO UPGRADING THEM AND MERCER CTY TO A WARNING WITH AN ADVISORY IN
SMYTH. OTRW INCREASING POPS OVERNIGHT/SUNDAY WITH TREND TOWARD LESS
SNOW PER WARM NOSE AND MORE MIX AT THE ONSET...THEN AGAIN LATE
NORTHERN HALF THRU SUNDAY. SOME ISOLATED TSRA ALSO POSSIBLE FAR SW
WHERE WEAK INSTABILITY AXIS KICKS IN. OTRW PRECIP SHOULD THEN CUT
BACK TO DZ/FZDZ SUNDAY NIGHT AS DEEP RH EXITS AND DRY SLOT KICKS IN
BEHIND DEPARTING SECONDARY COASTAL LOW. TEMPS MAINLY 30S
OVERNIGHT...THEN ABOUT STEADY SUNDAY WITH RISES INTO THE 40S IF NOT
50S FAR WEST.
LONG TERM /MONDAY THROUGH SATURDAY/...
MONDAY THROUGH THURSDAY...
5H LOW WILL REMAIN PARKED OVER THE GREAT LAKES REGION MONDAY/TUESDAY
BEFORE GETTING BOOTED OUT ACROSS THE MID ATLANTIC BY NEXT UPSTREAM
SYSTEM MIDWEEK. SPOKES OF ENERGY ROTATING THRU WILL MAKE FOR MAINLY
UPSLOPE SHOWERS...WITH MORE SNOW AT NIGHT AND MIX DURING THE DAY.
THUS PLANNING TO RUN WITH CHANCE POPS NW MON-TUE NIGHT AND THEN DRY
THINGS OUT WED-THU WHEN S/W RIDGING DEVELOPS. ELSEWHERE...DEEP
WESTERLY FLOW SHOULD LIMIT CLOUDS TO THE WEST SO MORE SUNSHINE
DEVELOPING OUT EAST AFTER SOME LINGERING CLOUDS ESPCLY MON. TEMPS
ABOUT NORMAL WITH COOL POCKET OVERHEAD AND WEAK CYCLONIC FLOW EARLY
ON.
THURSDAY NIGHT THROUGH SUNDAY...
NEXT FAST MOVING SOUTHERN WAVE AND ASSOCIATED FRONTAL SYSTEM WILL
QUICKLY PUSH INTO THE REGION THU NIGHT/FRIDAY BEFORE EXITING SAT.
THIS MAY BRING ANOTHER GOOD SHOT OF HEAVIER RAINFALL BY WEEKS END
BUT APPEARS WARM ENOUGH FOR MAINLY LIQUID AT THIS POINT.
AVIATION /20Z-18Z/...
VFR CONDITIONS WILL PREVAIL UNDER HIGH PRESSURE THIS AFTERNOON
BEFORE DETERIORATING INTO MVFR LEVELS TOWARD MIDNIGHT AS MOISTURE
INCREASES THIS EVENING. EXPECT PRECIP TO DEVELOP ACROSS THE NW BY
MIDNIGHT AND THEN ELSEWHERE BY MORNING AS A WARM FRONT SLOWLY LIFTS
NORTH INTO THE REGION. APPEARS PRECIP MAINLY A MIX OF RAIN/SLEET AT
THE ONSET...THEN TRANSITIONING TO MOSTLY RAIN...EXCEPT FREEZING RAIN
IN A CORRIDOR FROM LWB TO ROA AND LYH BY MID MORNING SUNDAY.
OCCLUDED TYPE FRONT EDGES TOWARD THE AREA FROM THE WEST BY AFTERNOON
SUNDAY WITH A MIX OF MVFR/IFR CONDITIONS PREVAILING IN RA/FZRA AND
