The radar

The Roanoke radar (KFCX), 97 km from the middle of the area, began a volume at 21:13 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, 9.2 hours before the alert went out and 62 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, Jul 5, 4:39 PM EDT, 33 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
439 PM EDT FRI JUL 5 2013

.SYNOPSIS...
A LARGE HIGH PRESSURE SYSTEM CENTERED OFF THE EAST COAST COVERED
MUCH OF THE EASTERN UNITED STATES. LOW PRESSURE OVER THE NORTHERN
PLAINS ON SATURDAY WILL MOVE EAST AND WILL PUSH A WEAK FRONT
ACROSS THE MID ATLANTIC REGION SUNDAY NIGHT AND MONDAY.

&&

.NEAR TERM /THROUGH SATURDAY/...
AS OF 401 PM EDT FRIDAY...

THE BERMUDA UPPER LEVEL RIDGE CONTINUES TO DRIFT TO THE WEST
STRETCHING INTO THE MID ATLANTIC COASTAL PIEDMONT. MEANWHILE...THE
CLOSED LOW OVER THE MID WEST WILL REMAIN NEAR THE OZARKS. A
SIGNIFICANT SHORT WAVE WILL RIDE UP THE TENN VALLEY AND BETWEEN THESE
TWO SYSTEMS. COMBINATION OF THIS WAVE AND AFTERNOON HEATING...STRONG
STORMS WITH HEAVY RAINFALL POTENTIAL IS EXPECTED TO MOVE UP THE
WESTERN SIDE OF THE SOUTHERN APPALACHIAN THIS EVENING. MODELS KEEP
THE BULK OF THE HEAVIEST RAIN WEST OF THE AREA AND ACROSS THE TENN-
SOUTHERN OHIO VALLEYS OVERNIGHT. I DO NOT THINK THE MODELS ARE
HANDLING THE CONVECTION COMING UP ACROSS SC/NC THIS
AFTERNOON/EVENING. BASED ON PERSISTENCE OF THE LAST COUPLE OF
DAYS...THESE STORMS WILL BRING AN ADDITIONAL CHANCE OF SHOWERS TO
THE NORTH CAROLINA HIGHLANDS OVERNIGHT. WILL MAINTAIN THE MOUNTAIN
EMPIRE AND GRAYSON HIGHLANDS IN A FLASH FLOOD WATCH INTO THIS
EVENING. THERE WILL BE A CONTINUED THREAT FOR SHOWERS OVERNIGHT INTO
SATURDAY OVER THE NORTH CAROLINA HIGHLANDS. THEREFORE HAVE EXTENDED
THE WATCH FOR ASHE...WATAUGA...AND WILKES COUNTY THROUGH SATURDAY
EVENING. SHOWERS WILL NOT BE CONTINUOUS BUT ANY MODERATE TO HEAVY
SHOWER...NO MATTER HOW BRIEF...WILL BRING CREEKS...STREAMS AND
RIVERS BACK TO OR ABOVE BANKFULL. IF THE THREAT WANES THROUGH THE
PERIOD...THE WATCH COULD BE CANCELED.

SHOWERS IN THE EAST ARE MORE DIURNALLY MOTIVATED AND WILL FADE WITH
LOSE OF HEATING THROUGH THE EVENING. WITH MORE HEATING OCCURRING IN
THE EAST...SOME STORMS COULD BECOME STRONG TO SEVERE.

THE WEATHER PATTERN MAY START TO CHANGE BEGINNING SATURDAY. THE
RIDGE MAY DRIFT SOUTHWEST WHILE THE LOW JOGS TO THE EAST-NORTHEAST.
THE PATH OF THE SHORT WAVES BETWEEN THESE TWO SYSTEMS WILL BEGIN TO
CLIP THE AREA. COMBINED A WEAK LEE TROUGH AND AFTERNOON
HEATING...MORE SCATTERED CONVECTION IS EXPECT ACROSS THE AREA
SATURDAY.

&&

.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
AS OF 412 PM EDT FRIDAY...

THE UPPER LEVEL LOW BEGINS TO DRIFT TO THE EAST SATURDAY NIGHT.
SHORT WAVES AND A POSSIBLE SURFACE WAVE COULD GENERATING HEAVY
RAINFALL ACROSS THE TENN AND SOUTHERN OHIO VALLEY SATURDAY NIGHT.
THESE SHOWERS WILL ADVANCE TO THE EAST SUNDAY...MOVING ACROSS THE
MOUNTAINS SUNDAY AFTERNOON. THESE CONVECTIVE SHOWERS MAY MOVE TO A
LEE TROUGH ACROSS THE PIEDMONT SUNDAY NIGHT (NAM) OR BECOME QUASI-
STATIONARY ALONG THE BLUE RIDGE (GFS). MODELS DISPLAYING CONVECTIVE
FEEDBACK BUT WITH SATURATED SOILS...EVEN A FRACTION OF THIS RAIN
COULD CAUSE PROBLEMS ACROSS THE MOUNTAIN AND FOOTHILL COUNTIES. IF
PROGGED CORRECTLY...THIS LINE OF SHOWERS WILL MOVE OVER THE PIEDMONT
MONDAY MORNING. WITH THE BLOCK RIDGE STILL TO OUR WEST...THE
EVOLUTION OF THIS LINE MAY BE SLOW TO ENTER THE AREA AND THEREFORE
SLOWER TO EXIT.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 428 PM EDT FRIDAY...

THE UPPER LEVEL RIDGE IS EXPECTED TO DRIFT OUT TO SEA ON TUESDAY.
ZONAL FLOW AND A MORE PROGRESSIVE WEATHER PATTERN WILL THEN BE
ESTABLISHED OVER THE REGION. EACH AFTERNOON AND EVENING WILL SEE
DIURNAL PULSE STORMS. ON FRIDAY...A WEAK FRONT WILL APPROACH THE
REGION AND POSSIBLY STALL NEAR THE AREA FOR A GREAT THREAT OF
WIDESPREAD SHOWERS AND THUNDERSTORMS OVER THE WEEKEND.&&

&&

.AVIATION /21Z FRIDAY THROUGH WEDNESDAY/...
AS OF 715 AM EDT FRIDAY...

FLIGHT CONDITIONS WILL CONTINUE TO BE QUITE VARIABLE AS THE DEEP
SOUTH TO SOUTHWEST FLOW REMAINS PERSISTENT ACROSS THE AREA...
WHICH IS BETWEEN ATLANTIC HIGH PRESSURE AND OHIO VALLEY LOW
PRESSURE.

KEPT MOST TAF SITES IN VICINITY SHOWERS THIS AFTERNOON AND EARLY
EVENING AS AREAL COVERAGE NOT ENOUGH TO INCLUDE IN TAFS. SIMILAR
TO PAST FEW DAYS...THUNDERSTORMS AND STRONGER SHOWERS WILL PRODUCE
HEAVY RAIN...ALONG WITH BRIEF MVFR CEILINGS AND VISIBILITIES.

LITTLE SIGNIFICANT CHANGE IS EXPECTED THROUGH EARLY NEXT WEEK.
VERY HUMID TROPICAL AIRMASS WILL SUPPORT CONTINUATION OF DAILY
SHRA/TSRA...YIELDING HEAVY RAINFALL RATES AND SUDDEN DROPS IN
VSBY. THE BEST PROBABILITY OF PRECIPITATION OVER THE WEEKEND WILL
BE FROM THE BLUE RIDGE WESTWARD...WHILE RAINFALL EAST OF THE
MOUNTAINS WILL BE MORE SPOTTY.

&&

.HYDROLOGY...

ALL FLOOD WARNINGS HAVE EXPIRED AT THIS TIME AND AREA RIVERS
CONTINUE TO RECEDE ALTHOUGH VERY SLOWLY IN SOME CASES. THE NEW
