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

Roanoke, VA (KRNK), launched 00:00Z, 3.2 hours before the alert went out and 107 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 27, 7:43 PM EDT, 3 hours 26 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
743 PM EDT THU MAY 27 2010

.SYNOPSIS...
A BACKDOOR COLD FRONT...MOVING WEST FROM CENTRAL VIRGINIA...SETTLES
EAST OF THE BLUE RIDGE ON FRIDAY. THE FRONT BECOMES STATIONARY AND
ERODES AS HIGH PRESSURE SINKS SOUTH WELL OFF THE ATLANTIC COAST.
SOUTHWESTERLY FLOW ARRIVES AHEAD OF A COLD FRONT EARLY NEXT
WEEK...THEN HIGH PRESSURE ARRIVES NEAR THE END OF THE WORK WEEK.

&&

.NEAR TERM /THROUGH FRIDAY/...
WITH THE AIRMASS USED MOSTLY ACROSS GREENBRIER COUNTY...CONVECTION
SHOULD WEAKEN LATER THIS EVENING WITH SUNSET. SOME STORMS COULD
STILL SLIP INTO NW PART OF GREENBRIER FROM DEVELOPMENT ACROSS
POCAHONTAS. EXPECTING A FEW MORE STORMS TO FIRE ACROSS EXTREME SW
VA AND NW NC THIS EVENING. SMALL HAIL AND HVY RAIN CAN OCCUR WITH
ANY REMAINING STORMS. AS BACKDOOR FRONT ARRIVES TONIGHT...PLENTY
OF FUEL REMAINS ACROSS THE VA PIEDMONT...AND AS THIS BOUNDARY
SETTLES JUST EAST OF THE BLUE RIDGE...IT WILL BECOME THE FOCUS FOR
NUMEROUS SHWS/TSTORMS INTO FRIDAY. INITIAL STORMS COULD BE SLOW
MOVERS TONIGHT...HOWEVER WILL BE MOVING MORE QUICKLY AS STRONGER
MID LEVEL FLOW ARRIVES ON FRIDAY. DESPITE THE QPF BOMB CONSISTENT
ON THE OP GFS...IF HVY RAINFALL DEVELOPS IN THE EAST TONIGHT...A
FLASH FLOOD WATCH MAY NEED TO BE CONSIDERED FOR THE NE CWA
CONSIDERING THE RAINFALL EXPECTED ON FRIDAY. SPC CONTINUES A SLT
RISK ACROSS MUCH OF THE CWA...WITH BETTER SHEAR POSSIBLY LEADING TO
DMGG WINDS ESPECIALLY EAST OF THE BLUE RIDGE ON FRIDAY.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
A BACK DOOR FRONT WILL CONTINUE TO PUSH SOUTH INTO NORTH CAROLINA
FRIDAY NIGHT. WIDESPREAD SHOWERS/THUNDERSTORMS WILL PERSIST ACROSS
NORTH CENTRAL NORTH CAROLINA OVERNIGHT...ALTHOUGH THE BULK OF THE
ACTIVITY WILL BE IN THE EVENING HOURS. CHANCES SLOWLY DECREASE
SATURDAY INTO SATURDAY NIGHT FROM NORTH TO SOUTH AS THE BOUNDARY
PROGRESSES SOUTHWARD. ITS PROXIMITY WILL STILL ALLOW FOR ISOLATED
SHOWERS/THUNDERSTORMS ACROSS SOUTHWESTERN VIRGINIA AND POINTS EAST
AND SOUTH. HIGH PRESSURE AT THE SURFACE AND ALOFT BUILDS IN SUNDAY
BRINGING IN DRIER AIR FROM THE NORTHEAST. SHOWERS SHOULD BE
DISSIPATING IF NOT GONE BY THE MORNING. HOWEVER...WITH DIFFERENTIAL
HEATING IN THE AFTERNOON...ISOLATED SHOWERS/THUNDERSTORMS ARE
POSSIBLE MAINLY IN SOUTHWEST VIRGINIA AND PORTIONS OF NORTH
CAROLINA.

1000-85H THICKNESSES ALONG WITH DECREASING CLOUDS WILL ALLOW MAX
TEMPERATURES TO RISE INTO THE LOWER 80S ACROSS THE FORECAST AREA
SUNDAY. TEMPERATURES THROUGH THIS PERIOD WILL BE NEAR TO SLIGHTLY
ABOVE SEASONAL NORMS.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
MODELS INDICATE ANOTHER BACK DOOR COLD FRONT PUSHING SOUTH OVER THE
COUNTY WARNING AREA THROUGH MID WEEK. WITH WEAK RETURN FLOW OF
MOISTURE ALONG WITH SOME HEATING OF THE AFTERNOON ON SUNDAY AND
MONDAY...AN ISOLATED SHOWER IS NOT OUT OF THE QUESTION. A FAIRLY
LIGHT WESTERLY REGIME WILL REMAIN THROUGH THE LONG TERM. STAYED
CLOSE TO HPC GUIDANCE THROUGH THE LONG TERM.

&&

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...
BLF AND LWB HAD SHOWERS AND THUNDERSTORMS THURSDAY AFTERNOON...SO
HAVE ADDED FOG AND STRATUS IN FOR BLF AND KEPT THE LIFR CONDITIONS
IN AT LWB OVERNIGHT.

THE CLUSTER OF SHOWERS AND THUNDERSTORMS IN SOUTH CENTRAL VIRGINIA
MAY APPROACH DAN LATER TONIGHT. FOR NOW HAVE LEFT OUT MENTION OF
ANY STORMS.

A COLD FRONT WILL MOVE FROM EASTERN VIRGINIA TOWARD THE BLUE RIDGE
ON FRIDAY. CONFIDENCE IS HIGH THAT THERE WILL MUCH MORE COVERAGE
OF SHOWERS AND THUNDERSTORMS...WITH THE MOST LIKELY PERIOD FOR
STORMS BEING FRIDAY AFTERNOON.

THIS BACKDOOR COLD FRONT WILL STALL OVER NORTH CAROLINA FRIDAY
NIGHT. SCATTERED TO NUMEROUS SHOWERS AND THUNDERSTORMS ARE
EXPECTED FRIDAY NIGHT THROUGH SATURDAY...BUT MAINLY DURING THE
PEAK HEATING PART OF THE DAY.

HIGH PRESSURE AND DRY WEATHER WILL ARRIVE ON SUNDAY.
