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
Roanoke, VA (KRNK), launched 12:00Z, 6.0 hours before the alert went out and 84 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 Jun 1, 1:15 PM EDT, 43 minutes earlier.
Area forecast discussion, Jun 1, 1:15 PM EDT, 43 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG VA 115 PM EDT FRI JUN 1 2007 .SYNOPSIS... HIGH PRESSURE OVER THE AREA WILL DRIFT EAST AND OFFSHORE THRU SATURDAY. LOW PRESSURE WILL DEVELOP AND MOVE NORTHEAST ALONG THE COAST SUNDAY AHEAD OF ANOTHER COLD FRONT APPROACHING FROM THE MIDWEST. && .NEAR TERM /THROUGH TONIGHT/... DEEPER MOISTURE REMAINS TRAPPED ACROSS THE REGION FOR THE AFTERNOON UNDER RIDGING AND WEAK SUBSIDENCE ALOFT PER 12Z DATA. HOWEVER GIVEN WEAK FORECAST CONVERGENCE ACROSS THE WEST SUSPECT WILL AGAIN HAVE AT LEAST WIDELY SCATTERED TSRA DESPITE WARMING ALOFT AND LACK OF S/W SUPPORT IN WAKE OF SYSTEM FROM THU. LATEST RUC SIMILAR TO THE NAM IN INDICATING A BAND OF CONVECTION ALONG/WEST OF THE BLUE RIDGE WHILE THE LATEST WRF MORE ISOLATED IN NATURE AND FOCUSED MAINLY ON OLD OUTFLOW BOUNDARIES. THUS UPPING POPS ACROSS THE SW/NW TO HIGHER CHANCE AND LEAVING ONLY SLIGHT CHANCES PIEDMONT WHERE RH ALOFT LESS PER GSO RAOB. MORNING THICKNESS GIVING HIGHS CLOSE TO GOING FORECAST VALUES SO ONLY TWEAKED HIGHS SOME IN THE WEST WHERE EARLY CLOUDS MAY LIMIT QUICK RISES. RELATIVELY MODEST INSTABILITY IN 1000-2000 J/KG RANGE AND LIFTED INDEX VALUES OF -2 TO -4 WILL AGAIN BE PRESENT THIS AFTERNOON...SO ISOLATED SEVERE IS NOT OUT OF THE QUESTION...BUT AGAIN...EXTENT IN TIME AND SPACE OF ANY SEVERE THREAT SHOULD BE MUCH LESS THAN YESTERDAY. ATMOSPHERIC FLOW REMAINS WEAK WITH LIMITED SHEAR...ONCE AGAIN IMPLYING MAINLY OUTFLOW DOMINATED CONVECTION AND RANDOM MOVEMENT ACCENTUATED BY LOCAL TOPOGRAPHIC INFLUENCES. CONCERN WILL BE CENTERED AROUND POTENTIAL FOR ISOLATED HEAVY RAINFALL CONSIDERING THE ANTICIPATED SLOW MOVEMENT OF STORMS THAT DO DEVELOP OVER THE HIGHER TERRAIN THIS AFTERNOON. OVERNIGHT LOWS TONIGHT SHOULD RANGE FROM THE MID AND UPPER 50S IN THE COOLER SHELTERED VALLEYS OF THE WEST WHERE SOME LATE NIGHT PATCHY FOG IS POSSIBLE...TO THE 60S ELSEWHERE. HARD TO SIGNIFICANTLY BEAT GUIDANCE WITH THIS TYPE OF SETUP. WENT WITH SOMEWHAT LOWER TEMPERATURES IN AREAS THAT RECEIVED ABUNDANT RAINFALL YESTERDAY... OTHERWISE CURRENT SET OF GRIDS LOOKED REASONABLE. && .SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/... NEAR TERM FORECAST DISCUSSION (ABOVE) APPLIES FOR WEATHER EXPECTED ON SATURDAY. MAXIMUM TEMPERATURES SHOULD BE BE A FEW DEGREES COOLER THAN THE PAST SEVERAL DAYS AS MID AND HIGH LEVEL MOISTURE BEGINS TO BE TRANSPORTED NORTHEAST IN ADVANCE OF DEVELOPING GULF COAST LOW PRESSURE SYSTEM...AND AS HEIGHTS/THICKNESSES SLOWLY FALL AS UPPER RIDGE RELAXES ITS GRIP OVER THE MID ATLANTIC REGION. && .LONG TERM /SUNDAY THROUGH THURSDAY/... WEATHER FOR SUNDAY INTO EARLY NEXT WEEK STILL HIGHLY DEPENDENT ON THE HANDLING OF ENERGY IN THE SOUTHERN STREAM THAT WILL ATTEMPT TO LIFT NORTHEAST INTO THE MID ATLANTIC REGION FROM OUT OF THE GULF COAST STATES. MID AND LONG RANGE MODELS STILL NOT CONSISTENT WITH TIMING OR STRENGTH OF THIS FEATURE. CURRENT THINKING IS THAT A BETTER THREAT OF SHOWERS/THUNDERSTORMS WILL OCCUR OVER THE REGION AS TEMPERATURES ALOFT COOL AS UPPER RIDGE MOVES OFFSHORE AND AS MID LEVEL MOISTURE IS ADVECTED NORTHEAST AROUND ITS PERIPHERY. TEMPERATURES WILL BE STRONGLY INFLUENCED BY AMOUNT OF RESULTING CLOUD COVER...AND WILL CONTINUE TO COOL AS A RESULT. THE THREAT FOR...AND AREAL COVERAGE OF PRECIPITATION WILL PERHAPS BE THE MOST PROBLEMATIC. STRONG CLOSED UPPER LOW PRESSURE WILL DRIFT EAST INTO THE UPPER GREAT LAKES AS THE LOWER LATITUDE SYSTEM LIFTS NORTHEAST OUT OF THE GULF COAST. WEAKENING FRONTAL BOUNDARY MOVING OUT IN ADVANCE OF THE NORTHERN SYSTEM AND ASSOCIATED CONVECTIVE LINE WILL LIKELY DECAY WEST OF THE BLUE RIDGE SUNDAY INTO MONDAY. MEANWHILE...SOUTHERN ENERGY MAY REMAIN JUST ENOUGH TO THE SOUTH OF THE BLACKSBURG AREA TO PLACE IT IN AN AREA OF SUBSIDENCE RATHER THAN BROAD UPWARD VERTICAL MOTION...RESULTING IN A LOWER THREAT FOR WIDESPREAD PRECIPITATION THAN WOULD BE IMPLIED BY MUCH WETTER AND WESTERN PLACED NAM. REGARDLESS OF FINAL SOLUTION...MID ATLANTIC REGION WILL SEE GRADUAL VEERING OF WINDS ALOFT ON BACKSIDE OF COASTAL SYSTEM...ALLOWING FOR INTRUSION OF SOMEWHAT COOLER AIR BY LATER MONDAY INTO TUESDAY. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... WIDELY SCATTERED THUNDERSTORMS WILL AGAIN DEVELOP IN THIS AFTERNOON...MAINLY FROM KROA WEST INTO SE WVA THRU EARLY THIS EVENING. SOME LOCALIZED IFR CONDITIONS ARE POSSIBLE IN SOME OF THE STRONGER STORMS...ALTHOUGH THE CHANCE OF A RESTRICTION AT ANY TAF POINT REMAINS LOW AND THEREFORE ONLY INCLUDING VICINITY TSRA MENTION AT THE WESTERN SITES. MORNING MVFR FOG AND HAZE...WITH LOCALIZED IFR CONDITIONS...ARE EXPECTED AGAIN TONIGHT IN 08Z-13Z TIME FRAME. SATURDAY...WILL CONTINUE WITH A PERSISTENCE FORECAST FOR EARLY MORNING MVFR FOG AND HAZE FOLLOWED BY AFTERNOON SCATTERED SHRA/TSRA MAINLY AT BLF/LWB. CONDITIONS WILL REMAIN VFR DURING THE DAYTIME PERIODS OUTSIDE OF THUNDERSTORM ACTIVITY UNDER AN INCREASING CANOPY OF MID/HIGH CLOUDS. SUNDAY AND MONDAY...THE THREAT FOR SHOWERS AND THUNDERSTORMS WILL INCREASE ALONG WITH ASSOCIATED MVFR/IFR CONDITIONS AS WEATHER DISTURBANCES APPROACH THE AREA FROM THE SOUTH AND WEST. TUESDAY...UPPER TROFING EXPECTED TO REMAIN OVER THE AREA...INDICATING A CONTINUED THREAT OF SOME MVFR CEILING RESTRICTIONS...MOST NOTABLY IN THE MORNING AND ALONG/WEST OF THE BLUE RIDGE. && .RNK WATCHES/WARNINGS/ADVISORIES...
