The radar
The Roanoke radar (KFCX), 37 km from the middle of the area, began a volume at 19:34 UTC, the scan nearest the moment this went out.
Open the radar archive at this moment
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, 7.5 hours before the alert went out and 73 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, May 7, 2:30 PM EDT, 1 hour 1 minute before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
230 PM EDT TUE MAY 7 2013
.SYNOPSIS...
EXPECT THE UPPER LOW TO TRACKS INTO VIRGINIA TODAY...THEN NORTH
INTO PENNSYLVANIA BY WEDNESDAY MORNING. THIS LOW WILL KEEP
SHOWERS IN THE FORECAST INTO WEDNESDAY...BEFORE THE SYSTEM LIFTS
OUT THURSDAY.
&&
.NEAR TERM /THROUGH TONIGHT/...
AS OF 1030 AM EDT TUESDAY...
CURRENTLY KEEPING AN EYE ON A BAND OF MODERATE TO OCCASIONALLY
HEAVY RAIN MAKING ITS WAY ACROSS THE AREA FROM AROUND BEDFORD INTO
OUR SOUTHEAST WEST VIRGINIA COUNTIES. A FEW LOCATIONS INSIDE THIS
BAND HAVE RECEIVED IN EXCESS OF TWO INCHES OF RAIN...WITH MORE ON
THE WAY. AS SUCH...WILL CONTINUE TO MONITOR FOR THE POTENTIAL OF
FLASH FLOODING UNTIL RAIN MOVES OUT OF THE AREA AROUND NOON...AND
THEN KEEP WATCH FOR LONGER TERM FLOODING OF CREEKS AND STREAMS.
AS DAYTIME HEATING INCREASES...WILL ALSO BE ON THE LOOKOUT FOR
THUNDERSTORM DEVELOPMENT...ESPECIALLY ACROSS NORTHERN NORTH
CAROLINA AND EXTREME SOUTHERN VIRGINIA...WHERE CLOUD COVER IS NOT
AS THICK AND MORE HEATING CAN REACH THE SURFACE. WITH THE UPPER
LEVEL LOW IN SUCH CLOSE PROXIMITY...CURRENTLY ROTATING ACROSS THE
MOUNTAINS OF SOUTH CAROLINA...DO NOT THINK IT WILL BE A MAJOR
STRETCH TO SEE THUNDERSTORMS REDEVELOP THIS AFTERNOON...A FEW
CONTAINING LARGE HAIL. REGARDLESS OF THUNDERSTORM INTENSITY...DID
INCREASE RAIN CHANCES ACROSS THIS AREA FOR THIS AFTERNOON AREAWIDE
AS LATEST RAPID UPDATE WEATHER MODELS AND LATEST RADAR TRENDS
INDICATE RAINFALL INCREASING WITH DAYTIME HEATING. EARLY MORNING
TEMPERATURE FORECAST APPEARS TO BE IN GOOD SHAPE FOR THE MOST
PART...WITH ONLY MINOR TWEAKS.
&&
.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
AS OF 400 PM EDT MONDAY...
THE UPPER LEVEL LOW WILL MOVE OVER NORTHERN VIRGINIA WEDNESDAY AND
WEDNESDAY NIGHT. THIS SYSTEM WILL GET KICK OUT TO SEA ON THURSDAY.
WRAP-AROUND SHOWERS WILL PUSH ACROSS THE MOUNTAINS THEN INTO THE
PIEDMONT DURING THE DAY. BY WEDNESDAY NIGHT...THE DAYTIME-DRIVEN
SHALLOW CONVECTIVE SHOWERS SHOULD DIE OFF QUICKLY AFTER
SUNSET...AS UPPER LOW CONTINUES TO LIFT NORTHEAST AND MOST OF FCST
AREA IS UNDER LIGHT NW FLOW. WE COULD SEE SOME MOUNTAIN SHOWERS
THURSDAY WITH LINGER MOISTURE AND SHORT WAVES TRACKING ON THE
OUTER RINGS OF THE DEPARTING LOW. HOWEVER...AREAL COVERAGE SHOULD
NOT EXCEED 20 PERCENT.
PERHAPS THE BIGGER DIFFERENCE IN THE WEATHER BETWEEN WED AND
THURS WILL BE A LITTLE MORE SUN BREAKING THROUGH AT TIMES DURING
THE DAY...WITH WARMER HIGH TEMPS...MOST LOCATIONS IN THE 70S. WENT
CLOSER TO COOLER ECWMF GUIDANCE...AS GFS GUIDANCE HAS MAX TEMPS AS
HIGH AS 80 IN PARTS OF THE EAST THURSDAY.
&&
.LONG TERM /FRIDAY THROUGH MONDAY/...
AS OF 400 PM EDT MONDAY...
UPPER TROUGH LIFTS OUT ACROSS NEW ENGLAND AS MID WESTERN WAVE SLIDES
IN BEHIND IT...WITH TAP OF GULF MOISTURE OUT AHEAD OF IT. BETTER
INSTABILITY AHEAD OF THIS FRONT IN SW FLOW FOR GOOD CHANCE OF
SCATTERED SHOWERS AND THUNDERSTORMS IN THE MOUNTAINS MAINLY BY
FRIDAY. MEDIUM RANGE MODELS IN FAIRLY GOOD AGREEMENT THAT FRONTAL
BOUNDARY THEN APPROACHES WESTERN APPALACHIANS BY LATE IN THE DAY
SATURDAY FOR BETTER COVERAGE IN WEST ESPECIALLY. WENT WITH HIGH CHC
TO LOW LIKELY POPS FOR SATURDAY AND SHOULD SEE BEST COVERAGE OF
THUNDERSTORM ACTIVITY OF THE SEASON SO FAR.
BY SUNDAY MORNING THE INITIAL FRONT PUSHES THROUGH THE REGION TAKING
MOST MOISTURE WELL TO THE SOUTH...BUT SECONDARY FRONT WITH MUCH
COOLER AIR BEHIND LAGS BEHIND...ESPECIALLY IN GFS...AS UPPER TROUGH
DIGS INTO EASTERN U.S. GIVEN UNCERTAINTY OF JUST HOW MUCH LOW LEVEL
MSTR WILL BE LEFT AHEAD OF THIS SECONDARY FRONT...AND SOME
INSTABILITY UNDER UPPER TROUGH DEPENDING ON ANY SUNSHINE...BEST TO
LEAVE AT LEAST SOME LOW CHC POPS AHEAD OF THIS BOUNDARY FOR
SUNDAY...BUT ANYTHING THAT DOES FORM WILL BE MAINLY IN MOUNTAINS
WITH WLY FLOW...AND SHOULD DIE QUICKLY BY LATE IN THE DAY AS
DRIER AIR PUSHES IN AND MAX HEATING WANES.
LATEST GUIDANCE SHOWS MUCH LOWER DEW PTS BY SUN NIGHT AND IF
CLEARING CAN OCCUR...MIN TEMPS MAY DROP INTO THE LOWER 40S OR EVEN
UPPER 30S MTNS. COOLER BUT DRY DAY MONDAY AS SFC HIGH BUILDS IN AND
UPPER TROF BEGINS TO SHIFT TO NEAR COAST...AND WE WILL HAVE TO KEEP
AN EYE ON FROST POTENTIAL FOR MONDAY NIGHT WITH SFC HIGH DIRECTLY
OVERHEAD.
&&
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
AS OF 145 PM EDT TUESDAY...
NUMEROUS SHOWERS WITH EMBEDDED THUNDERSTORMS COVERED MUCH OF THE
REGION THIS AFTERNOON. LOW PRESSURE OVER THE SOUTHERN APPALACHIANSWILL
MOVE SLOWLY NORTHEAST INTO EASTERN PENNSYLVANIA TONIGHT INTO
WEDNESDAY. THIS WILL RESULT IN SEVERAL PERIODS OF SHOWERS WITH
LIGHT TO MODERATE RAIN AND MVFR TO IFR CEILINGS AND VISIBILITIES
THROUGH WEDNESDAY NIGHT.
SPECIFICALLY...SCATTERED SHOWERS AND THUNDERSTORMS WILL DEVELOP
EAST OF THE BLUE RIDGE THIS AFTERNOON AND MAY IMPACT ROA/LYH AND
DAN. THE MORE WIDESPREAD SHOWERS WILL CONTINUE OVER BCB/BLF AND
LWB THROUGH 00Z. EXPECT THERE WILL BE A BREAK IN THE SHOWERS AFTER
00Z...BUT WITH ABUNDANT LOW LEVEL MOISTURE AND LIGHT WINDS...FOG
AND STRATUS WILL DEVELOP OVERNIGHT. HAVE ADDED LIFR FOG AND
STRATUS...MAINLY AFTER MIDNIGHT AND CONTINUING UNTIL JUST AFTER
SUNRISE. FOG WILL DISSIPATE AND CEILINGS WILL IMPROVE TO MVFR BY
14Z/10AM.
WEDNESDAY WILL BE ANOTHER DAY WITH SCATTERED SHOWERS AND
THUNDERSTORMS...ESPECIALLY IN THE AFTERNOON. HAVE NOT INCLUDED IN
THE TAFS AT THIS TIME...BUT MAY BE ADDED IN LATER FORECAST. ANY
SUN AND HEATING WILL INCREASE THE PROBABILITY OF SHOWERS AND
THUNDERSTORMS DUE TO THE COLDER AIR ALOFT ASSOCIATED WITH THE
UPPER LOW AND THEREFORE THE MORE INSTABILITY.
BY THURSDAY THE UPPER LOW WILL BE TO THE NORTHEAST. THURSDAY AND
FRIDAY EXPECT DRY AND WARMER WEATHER...WITH VFR CONDITIONS DURING
THE DAY AND PATCHY MVFR FOG AT NIGHT. A COLD FRONT CROSSING
THROUGH THE REGION ON SATURDAY WILL BRING ANOTHER CHANCE OF
SHOWERS AND THUNDERSTORMS...WITH COOLER AND DRIER WEATHER AND
LIKELY VFR CONDITIONS ON SUNDAY.
&&
.HYDROLOGY...
AS OF 200 PM EDT MONDAY...
AS OF THIS AFTERNOON...WATER LEVELS IN A FEW MOUNTAIN CREEKS AND
RIVERS NORTH OF INTERSTATE 81 CONTINUE TO RISE DUE TO PERIODS OF
HEAVY RAIN WHICH FELL DURING THE MORNING. MUCH OF THE RAIN HAS
DIMINISHED IN INTENSITY...BUT CONTINUES TO FALL STEADY ACROSS THE
MOUNTAINS. NEW RAINFALL AMOUNTS WILL BE BETWEEN A HALF INCH TO AN
INCH THROUGH MIDNIGHT.
IN THE MOUNTAINS SOUTH OF THE INTERSTATE...SHOWERS AND THUNDERSTORMS
HAVE DEVELOPED WITH AFTERNOON HEATING...AND HAVE BECOME SCATTERED TO
WIDESPREAD. UP TO AN INCH OF RAIN IS POSSIBLE WITHIN THE HEAVIER
ACTIVITY. SOME RAIN IS DEVELOPING ACROSS AREAS WHICH RECEIVED
SEVERAL INCHES OF RAINFALL WITHIN THE LAST DAY. DUE TO SATURATED
SOIL CONDITIONS IN THESE AREA...ANY RAINFALL THIS AFTERNOON AND
EVENING MAY BE CONVERTED DIRECTLY INTO RUNOFF. THEREFORE...A FLASH
FLOOD WARNING HAS BEEN THROUGH MIDNIGHT.
