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 severe thunderstorm 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 00:00Z, 0.0 hours before the alert went out and 136 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Blacksburg, VA wrote its last area forecast discussion before this severe thunderstorm warning went out at May 9, 7:42 PM EDT, 18 minutes earlier.

Area forecast discussion, May 9, 7:42 PM EDT, 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BLACKSBURG VA
742 PM EDT FRI MAY 9 2008

.SYNOPSIS...
A COLD FRONT HAS MOVED THROUGH THE FORECAST AREA.  AN UPPER LEVEL
DISTURBANCE WILL CROSS THE AREA TONIGHT.  ANOTHER STRONG AREA OF
LOW PRESSURE WILL TRACK ACROSS THE REGION SUNDAY.

&&

.NEAR TERM /UNTIL 9 PM THIS EVENING/...
HAVE EXPANDED CHANCE OF RAIN INTO THE EASTERN COUNTY WARNING AREA
BASED ON THE LATEST RADAR TRENDS. NO OTHER CHANGES AT THIS TIME.

&&

.SHORT TERM /9 PM THIS EVENING THROUGH MONDAY NIGHT/...
SKIES MANAGED TO CLEAR SOMEWHAT TODAY...MORE SO OVER THE SOUTHERN
CWA THAN IN THE NORTH. CURRENTLY MONITORING AN UPPER LEVEL
DISTURBANCE COMING ACROSS THE OHIO VALLEY...WATER VAPOR IMAGERY
CAPTURES IT PRETTY WELL. THIS FEATURE WILL PROVIDE AN OPPORTUNITY
FOR SHOWERS AND A FEW THUNDERSTORMS DURING THE OVERNIGHT...BUT
SHOULD CLEAR THE AREA SATURDAY MORNING. IN ADDITION TO THE THREAT
OF SHOWERS...THE MOIST GROUND WILL PROMOTE SOME LATE NIGHT FOG AND
STRATUS...ESP AREAS THAT DID NOT HAVE A CHANCE TO MIX OUT VERY
WELL FRIDAY.

CLOUDS...FOG AND SHOWERS SHOULD DEPART FOR A FAIR SATURDAY
AFTERNOON. BREAKS IN THE CLOUD COVER MAY BE SLOW TO DEVELOP
(SIMILAR TO FRIDAY)...BUT AT LEAST THERE SHOULD NOT BE ANY PCPN.
TEMPS WILL BE THE WARMEST IN THE SRN CWA...COOLEST IN THE NORTH
WHERE CLOUDS WILL BE SLOWER TO DEPART.

WITH SHRT RNG MODELS DEPICTING A STRONG WEDGE IN PLACE...DID LOWER
MAX T SEVERAL DEGREES ON SUNDAY. THIS SHOULD SHIFT THE
OPPORTUNITY FOR STRONGER STORMS EITHER OUT OF THE CWA...OR ALONG
THE PIEDMONT WHERE WARM FRONT/STRNG LLVL SHEAR MAY STILL ARRIVE
LATE DAY. HOWEVER...FOR NOW...SPC HAS SHIFTED SLIGHT RISK SOUTH OF
OUR REGION. HVY RAIN MAY DEVELOP WITH WARM HUMID AIRMASS GETTING
FORCED OVER COOL WEDGE. AS USUAL...ANY TSTORMS WHICH DEVELOP ALONG
THE FRONT MAY ROB MOISTURE FLUX THIS FAR NORTH. DESPITE
THIS...WITH BOTH NAM/GFS ON BOARD FOR HVY RAINFALL...A FLOOD WATCH
IWILL NEED TO BE CONSIDERED ON FUTURE SHIFTS WITH THE HVY RAIN
WHICH ALREADY FELL THURSDAY. ALSO...STRENGTHENING LOW PRESSURE
WRAPPING UP OFF DELMARVA IS TAKING A FAVORABLE TRACK FOR GUSTY
WINDS...ESPECIALLY ALONG THE HIGHEST SPOTS SUNDAY NIGHT/MONDAY
MORNING.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
SEVERAL FACTORS ON THE H5 CHART WILL LEAD TO A POTENTIALLY ACTIVE
END OF NEXT WEEK. THE CLOSED UPPER HIGH NORTH OF HUDSON
BAY...WHICH BROKE OFF FROM PERSISTENT RIDGING ACROSS THE NORTH
ATLANTIC...WILL HELP TO FORCE ENERGY BREAKING OFF FROM A STRONG
GYRE SW OF ALASKA...INTO THE MIDWEST. CLOSER TO HOME...THE AREA OF
LOW PRESSURE PASSING THROUGH THE MIDDLE ATLANTIC ON SUNDAY WILL
STRENGTHEN OFF THE EAST COAST AND HEIGHTS WILL INCREASE BEHIND IT
AND AHEAD OF A STRONGER CLOSED H5 LOW EVOLVING IN THE MIDWEST. THE
BIG QUESTION IS...WILL THIS LOW DISPLACE THE OMEGA SIGNATURE MORE
OFF THE EAST COAST /GFS/...OR WILL IT STALL WEST OF THE CWA AND
DIG /ECMWF/ INTO THE GULF COAST STATES? IF THE ECMWF
VERIFIES...THE END OF THE WEEK AND NEXT WEEKEND COULD VERY WET.
DIDNT MAKE MANY CHANGES TO CURRENT FORECAST CONSIDERING THE
ECMWF/GFS DIFFERENCES...BUT TRIED TO LEAN INTO THE ECMWF SOLUTION
BASED UPON ITS RECENT PERFORMANCE.

&&

.AVIATION /00Z SATURDAY THROUGH WEDNESDAY/...
LOW CLOUDS WITH CONVECTION AND FOG WILL HINDER AVIATION OPERATIONS
DURING THE PERIOD. MOUNTAIN OBSCURATIONS AND TURBULENCE ARE POSSIBLE
ESPECIALLY IN THE WEST. PILOTS SHOULD CHECK AIRMETS AND SIGMETS. AN
UPPER LEVEL DISTURBANCE WILL BRING SCATTERED SHOWERS TO THE AREA
TONIGHT...BUT OF MORE CONCERN WILL BE THE MOIST GROUND AND
BOUNDARY WHICH WILL PROMOTE THE FORMATION OF FOG AND STRATUS.
AREAS OF LIFR/IFR FOG ARE POSSIBLE BETWEEN 08Z AND 14Z AT KLWB AND
THE GREENBRIER VALLEY OF WEST VIRGINIA. CLOUDS WILL BE SLOW TO
CLEAR SATURDAY...BUT WILL TRANSITION LOWER AGAIN FOR SATURDAY
NIGHT AND SUNDAY AS ANOTHER SYSTEM APPROACHES FROM THE WEST.

THE WEATHER PATTERN IS FAVORING THE PASSAGE OF MORE FRONTAL
SYSTEMS FOR NEXT WEEK. THIS WILL RESULT IN FEWER VFR BREAKS WITH
SHOWERS AND THUNDERSTORMS RESULTING IN AREAS OF MVFR/IFR
CONDITIONS. THE MOIST GROUND WILL ALSO FAVOR AREAS OF LATE NIGHT
FOG AND STRATUS.

&&

.HYDROLOGY...
THURSDAY NIGHT RAINFALL IN THE UPPER DAN BASIN RANGED FROM 2 TO 4
INCHES WITH ISOLATED 5 INCH+ AMOUNTS IN PARTS OF HENRY COUNTY.
BASINWIDE AVERAGE RAINFALL ABOVE DANVILLE WAS IN THE 2.5 TO 3 INCH
RANGE.

RIVER FLOOD WARNINGS WERE ISSUED FRIDAY MORNING FOR THE
DAN FROM DANVILLE TO SOUTH BOSTON. THE DAN ROSE ABOVE FLOOD STAGE
EARLY FRIDAY AFTERNOON AND IS FORECAST TO CONTINUE ITS RAPID RISE
AND CREST NEAR 22 FEET AFTER MIDNIGHT. THIS IS CONSIDERED
MODERATE FLOOD STAGE AT DANVILLE...ALTHOUGH SERIOUS PROBLEMS DO
NOT GENERALLY OCCUR BELOW 22 OR 23 FEET. THE DAN WILL CONTINUE TO
RISE RAPIDLY DOWNSTREAM AT PACES AND SOUTH BOSTON...THOUGH NOT
REACHING FLOOD STAGE UNTIL SATURDAY. NO SUBSTANTIAL RAINFALL IS
FORECAST THROUGH SATURDAY WHICH MAKE RIVER FORECASTS LESS
PROBLEMATIC.

MEANWHILE THE ROANOKE RIVER BELOW SMITH MOUNTAIN LAKE AND
DOWNSTREAM OF BROOKNEAL HAS RISEN SIGNIFICANTLY. THE RIVER IS
EXPECTED TO REACH NEAR BANK FULL. MINOR FLOODING IS FORECAST AT
RANDOLPH.
