The radar
The Roanoke radar (KFCX), 126 km from the middle of the area, began a volume at 18:40 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.
Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.
The nearest sounding before it
Greensboro/Hi Pt, NC (KGSO), launched 12:00Z, 6.7 hours before the alert went out and 108 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
115 PM EDT THU MAY 28 2009
.SYNOPSIS...
A COLD FRONT WILL APPROACH FROM THE WEST THIS AFTERNOON AND THEN
PASS OFFSHORE ON FRIDAY. LINGERING TROPICAL MOISTURE AHEAD OF THE
FRONT WILL RESULT IN ADDITIONAL SHOWERS AND THUNDERSTORMS
ESPECIALLY THIS AFTERNOON INTO TONIGHT. DRIER WEATHER SHOULD
FINALLY MAKE A RETURN BEHIND THE FRONT OVER THE WEEKEND AS HIGH
PRESSURE BUILDS IN FROM THE WEST.
&&
.NEAR TERM /THROUGH TONIGHT/...
SURFACE FLOW HAS BECOME MORE SOUTHWESTERLY THROUGH THE MORNING
WHILE FLOW ALOFT IS WESTERLY. DESPITE A LEE TROUGH IN THE
EAST...THIS WESTERLY FLOW IS NEUTRALIZING SHOWERS IN THE PIEDMONT
THIS MORNING. BREAKS IN THE CLOUDS ARE EXPECTED AND CONVECTIONAL
COVERAGE WILL INCREASE THROUGH THE AFTERNOON AS
HEATING/INSTABILITIES INCREASES.
PREFRONTAL CONVECTION WILL FIRE IN THE AFTERNOON AS A COLD FRONT
APPROACHES THE AREA. LOCAL WRF DISPLAY A FEW SHORT WAVES MOVING
ACROSS SE WV THIS AFTERNOON AND THIS AREA WILL HAVE THE BETTER
COVERAGE OF SHOWERS. ELSEWHERE ACROSS THE MOUNTAINS...RESIDUAL
BOUNDARIES...OROGRAPHICAL INFLUENCES AND AFTERNOON HEATING WILL
SPARK SCATTERED SHOWERS AND THUNDERSTORMS THIS AFTERNOON. SPC SLIGHT
RISK STILL REMAINS WEST OF THE AREA BUT CAN NOT RULE OUT ISOLATED
SEVERE WEATHER THREAT AS INSTABILITIES INCREASE THIS AFTERNOON.
WITH PLENTY OF MOISTURE AND SATURATED GROUND...WILL LEAVE FLASH
FLOOD WATCH IN EFFECT AS AFTERNOON CONVECTION COULD PRODUCE LOCALIZE
FLOODING.
SOME LOW LEVEL CLOUDINESS REMAINING IN THE AREA TO KEEP SOME
TEMPERATURES A LITTLE COOLER. AS THE AFTERNOON PROGRESSES...BREAKS
IN THESE CLOUDS WILL HAVE TEMPERATURES RISING RATHER QUICKLY. STILL
LOOKING AT NEAR NORMAL AND MUGGY CONDITIONS THROUGH THIS EVENING.
PREVIOUS DISCUSSION...FLOW HAS FINALLY VEERED AROUND TO A BIT
MORE SOUTH/SW TRAJECTORY ALOFT THIS MORNING ALLOWING SHRA TO BE
MORE PROGRESSIVE AND LESS BANDED. HOWEVER CONCERN AGAIN WITH
FLOODING POTENTIAL ESPCLY OVER THE WEST THRU THIS EVENING AS THE
UPSTREAM COLD FRONT BEGINS TO INTERACT WITH THE RESIDUAL TROPICAL
MOISTURE IN PLACE. AFTER RAINFALL FROM WED...LATEST 1 HOURLY FLASH
FLOOD GUIDANCE VALUES QUITE LOW WEST OF THE BLUE RIDGE WITH SOME
AREAS DOWN CLOSE TO A HALF INCH NEEDED TO PRODUCE FLOODING. EXPECT
WHATS LEFT OF PRE- FRONTAL CONVECTION OVER TN/KY TO ENTER THE WEST
EARLY THIS MORNING BEFORE FADING. THEN AS DECENT S/W ROUNDS TOWARD
THE APPALACHIANS LATE WILL SEE ANOTHER BAND OF TSRA TO THE WEST
AND CLUSTERS OF SHRA/TSRA DEVELOP ALONG/WEST OF THE BLUE RIDGE BY
AFTERNOON PER MORE HEATING TODAY. ALTHO THE FLOW IS A BIT
STRONGER...UNIDIRECTIONAL CHARACTER COULD LEAD TO SOME
MULTICELLUAR BANDS AS DEPICTED BY THE LATEST LOCAL WRF. HOWEVER
MORE WESTERLY FLOW WILL LIKELY CAUSE A JUMP TO THE PIEDMONT LEE
TROF LATER ON AS PWATS FINALLY DROP WEST BUT HOW FAST THIS HAPPENS
TRICKY. THEREFORE GIVEN HOW LITTLE QPF IT TOOK TO PRODUCE FLOODING
WED...WILL RAISE ANOTHER WATCH OVER THE WEST IN AREAS THAT HAVE
THE LOWEST FFG THRU EARLY TONIGHT. EASTERN AREAS SHOULD BE ABLE TO
HANDLE MORE QPF SO WILL LEAVE ISOLATED FLOODING MENTION FOR THE
EAST IN THE HWO. OTRW BOOSTED POPS TO LIKELY/CAT ALONG THE BLUE
RIDGE AND POINTS EAST WHERE ACTUALLY EXPECT THE BEST COVERAGE TO
END UP BY EVENING PER NAM CAPES/THETA-E AXIS. ALSO TWEAKED HIGHS
DOWN SOME GIVEN WARM MOS OF LATE EXCEPT SE WHERE MORE IN THE WAY
OF MID 80S LIKELY.
S/W SHOULD PUNCH HEAVIER SHRA EAST THIS EVENING WITH SOME DRYING IN
BETWEEN THE DEPARTING LEE TROF CONVECTION AND THE COLD FRONT
NEARING THE WESTERN SLOPES BY MORNING. LINGERING INSTABILITY
SUPPORTS KEEPING TSRA MENTION MAINLY EAST EARLY ON THEN HIGHER
CHANCE SHRA SE AND NW AFTER MIDNIGHT AS A MORE PRONOUNCED WESTERLY
FLOW TAKES SHAPE. EXPECT LOW TEMPS TO BE A LITTLE COOLER WEST WHERE
DEWPOINTS SHOULD FALL A LITTLE IN THE WAKE OF THE PASSING CONVECTION
OVERNIGHT. OTRW MAINLY LOW/MID 60S WITH A FEW 50S LIKELY IN THE
VALLEYS.
&&
.SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/...
ALTHOUGH THE SURFACE COLD FRONT IS PROGGED ACROSS ROANOKE FRIDAY
MORNING...UPPER WAVE LAGS A BIT...AND WITH SOME SUNSHINE POPPING
THROUGH...THERE WILL BE ENOUGH INSTABILITY AND MOISTURE FOR PRECIP
IN THE AFTERNOON. CLDS AND WNW TO NW WIND MAY KEEP LWB/BLF COOLER
THAN GRIDS FRIDAY. HIGHER POPS MAY NEED TO BE PUSHED BACK INTO THE
NEW RIVER VALLEY. WITH AN UPPER LOW SITTING OVER HUDSON BAY AND
RESULTING SE CANADIAN TROUGH...TROUGHINESS WILL REMAIN ACROSS NEW
ENGLAND. THUS...ANOTHER BOUNDARY WILL RESIDE ACROSS THE NORTHERN
HALF OF THE CWA INTO THE WEEKEND. MUCH DRIER AIR AND A WESTERLY
COMPONENT WILL WORK AGAINST WIDESPREAD SHWS AND TSTORMS. COLD
FRONT ARRIVING ON SUNDAY MAY ALLOW MORE DEVELOPMENT ON
THEN...ALTHOUGH THE BEST CAA AND UPPER SUPPORT SEEMS TO PASS NORTH.
UPPER RIDGE ACROSS THE WESTERN ATLANTIC SPREADS BACK WEST ON
MONDAY...CAPPING ANY THUNDERSTORM GROWTH ON MONDAY FROM RESIDUAL
BOUNDARY.
&&
.LONG TERM /MONDAY THROUGH WEDNESDAY/...
EAST COAST UPPER LEVEL TROUGH WILL BE REPLACED WITH INCREASING
HEIGHTS FROM AN UPPER LEVEL RIDGE. WITH A SOUTHWEST FLOW AND
INCREASING MOISTURE EACH DAY NEXT WEEK...TYPICAL SUMMER-TIME
ISOLATED/SCATTERED SHOWERS AND THUNDERSTORMS CAN BE EXPECTED. MOST
OF THE CONVECTION WILL BE OROGRAPHICAL GENERATED AND REMAIN IN THE
MOUNTAINS. TUESDAY AND WEDNESDAY AFTERNOON...A FEW OF THESE STORMS
MAY DRIFT EAST OF THE BLUE RIDGE. PATTERN DOES NOT LOOK GOOD FOR
ORGANIZED CONVECTION...THEREFORE WILL KEEP POPS IN THE 20/30 PERCENT
RANGE. IF THE RIDGE CENTER IS FARTHER TO THE SOUTH AND MORE ZONAL
FLOW IS OVER THE REGION...WILL NEED TO KEEP AN EYE TO THE WEST AS
DECAYING MID WEST MESOSCALE COMPLEXES COULD MOVE THROUGH THE AREA.
SEASONABLE TEMPERATURES ARE EXPECTED THIS WEEKEND AND INTO THE MIDDLE
PART OF NEXT WEEK. MOS GUIDE BIAS CORRECTED GRIDS WERE USED FOR
MAXIMUM TEMPERATURES WHILE MINIMUM TEMPERATURES WERE POPULATED WITH
HPCGUIDE.
&&
.AVIATION /18Z THURSDAY THROUGH MONDAY/...
SHOWERS AND SCATTERED TSTMS ARE DEVELOPING THIS AFTERNOON...WITH
THE BEST COVERAGE BETWEEN 18Z AND 23Z. SHOWERS AND TSTMS THIS
AFTERNOON WILL HAVE THE POTENTIAL FOR VERY HEAVY RAIN AGAIN...SO
FLIGHT CONDITIONS HAVE A GOOD CHC TO DROP BRIEFLY TO MVFR/IFR IN
PASSING STORMS. SHRA/TSRA SHOULD LINGER IN THE EAST EARLY TONIGHT
BEFORE MOST PRECIP GIVES WAY TO FOG AND PERIODS OF LOW CLOUDS
OVERNIGHT. FRONT SHOULD CLEAR THE SE WVA SITES BY MORNING BUT WEST
WINDS LIKELY NOT ENOUGH TO KEEP KLWB FROM LOWERING TO MVFR/IFR IN
FOG AS WELL AS KBLF WHERE WESTERLY FLOW MAY ENHANCE LOW CLOUDS.
MVFR TO IFR CONDITIONS WILL EXIST PERIODICALLY ACROSS THE AREA
FRIDAY MORNING WITH ABUNDANT MOISTURE AND SCATTERED SHOWERS...UNTIL
A COLD FRONT PASSES THROUGH THE REGION LATER FRIDAY. HIGH
PRESSURE THEN BUILDS IN OVER THE WEEKEND INTO EARLY NEXT WEEK WITH
A RETURN TO OVERALL VFR OUTSIDE OF ISOLATED AFTERNOON SHRA/TSRA
THAT MAY DEVELOP ON SUNDAY OR MONDAY.
&&
.HYDROLOGY...
1 HR FFG REMAINS VERY LOW WEST OF THE BLUE RIDGE WITH VALUES OF 0.75
AND 1.25 IN/HR BUT A BIT HIGHER IN THE EAST. WITH ANOTHER ROUND OF
CONVECTION LIKELY THIS AFTERNOON/EVENING POTENTIAL AGAIN EXISTS FOR
POSSIBLE ISOLATED FLASH FLOODING PENDING JUST WHERE THE HEAVIER
TSRA DEVELOP. MODEL CONSENSUS SEEMS TO POINT TO BETTER COVERAGE IN
THE EASTERN AREAS ALTHO IT WOULDNT TAKE MUCH TO PRODUCE FLOODING
ACROSS THE WEST WHERE HEAVY RAIN HAS PERSISTED THE LAST FEW DAYS.
THUS HAVE CONTINUED FLASH FLOOD WATCH FOR MUCH OF THE AREA
WEST OF THE BLUE RIDGE FOR ISOLATED FLASH FLOODING INTO THIS
EVENING.
