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
Roanoke, VA (KRNK), launched 12:00Z, 10.1 hours before the alert went out and 221 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, Aug 3, 3:54 PM EDT, 2 hours 12 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHARLESTON WV 354 PM EDT FRI AUG 3 2007 .SYNOPSIS... THE HEAT WAVE CONTINUES INTO NEXT WEEK. WHAT IS LEFT OF A DISSIPATING FRONT SHOULD IN OUR VICINITY ON SATURDAY. UPPER AIR DISTURBANCE SWINGS THROUGH ON SUNDAY COULD TRIGGER MORE WIDESPREAD CONVECTION AND CLOUDS...AND KEEP AFTERNOON TEMPERATURES DOWN A BIT. && .NEAR TERM /THROUGH SATURDAY NIGHT/... TCU ARE BEGINNING TO DEVELOP IN THE HUMID AIRMASS AS OF 17Z. ONE CLUSTER OF STORMS IS MOVING THROUGH ERN KY WHILE ANOTHER AREA IS LOCATED IN THE HIGHER TERRAIN OF THE WV MTNS. NO REAL UPPER SUPPORT TO FOCUS DETERMINISTIC POPS ON THIS AFTN AND EVNG. A WEAK TROUGH OF LOW PRESSURE ENCROACHES FROM THE NW TONIGHT...BUT BY THEN A DECENT CAP WILL ESTABLISH. NAM AND GFS DIFFER ON THE PLACEMENT OF THE FRONT BY 12Z SATURDAY. GFS CONTS TO BE THE DRIER AND FARTHER SE MODEL...WHILE THE NAM AND SREF HOLD THE FRONT ALONG THE M/D LINE WITH H8 MSTR POOLING ALONG THE BOUNDARY. CONTD TO ROLL WITH A DRY FCST SAT UP NORTH WITH THE FOCUS ON THE BETTER INSTABILITY OVER THE MTNS AND SRN COAL FIELDS /SCHC POPS/. DEWPOINTS FALL INTO THE LWR 60S IN THE N GIVEN WE OPTED FOR THE GFS SLTN...WHILE THE MUGGIES PERSIST S WITH U60S FOR TD. WIDESPREAD HAZE TODAY WILL BE LESS TMRW AS SOMEWHAT FRESHER AIR INFILTRATES FROM THE LOWER GREAT LAKES. && .SHORT TERM /SUNDAY THROUGH MONDAY NIGHT/... STILL UNCLEAR ON HOW SUNDAY WILL TURN OUT. CAN NOT TOTALLY JUMP ONTO 12Z GFS WHICH LAGS VORT MAX BACK IN SRN OHIO AT 18Z SUNDAY IN WNW FLOW ALOFT. BOTH NAM AND GFS AGREE THERE COULD BE SOME MORNING PCPN AT 12Z SUNDAY IN THE W AND N. QUESTION IS DOES THAT MOVE ACROSS MOUNTAINS DURING THE AFTERNOON...THEN DOES WESTERN COUNTIES DRY OUT IN THE PM...OR DOES MORE CONVECTION FIRE AND CROSS SOUTHERN COUNTIES DURING AFTERNOON AND EVENING. THE LOW LEVEL INFLOW IS CERTAINLY NOTHING TO WRITE HOME ABOUT. DID INCREASE POPS INTO THE 40 TO 50 POP RANGE...AT THIS DISTANCE IN TIME...FOR CENTRAL AND NRN COUNTIES. DO THINK THE CLOUDS AND PCPN COULD CERTAINLY HINDER MAXIMUM TEMPERATURE ON SUNDAY. LOWERED MAX TEMPS INTO MID 80S ACROSS THE NORTH INCLUDING CKB. OF COURSE... EVERYTHING IS DEPENDENT ON THE CONVECTION PATTERN. BUILDING 500 MB HEIGHTS ON MONDAY...BUT HAD TO KEEP 20 TO 30 POPS FOR LEFTOVER MOISTURE AND INSTABILITY. && .LONG TERM /TUESDAY THROUGH FRIDAY/... 500 MB RIDGE WILL TRY TO BULGE NORTH TUESDAY AND WEDNESDAY. WENT A BIT HOTTER THAN HPC GUIDANCE TEMPERATURES WITH SOME UPPER 90S. DEW POINTS WILL BE INCREASING BUT THINK HEAT INDEX WILL REMAIN AB 105 IN THE USUAL HOT SPOTS. MAIN FRONTAL ZONE REMAINS OVER SOUTHERN GREAT LAKES DAY 4/5. THOUGHT SOME OF THE HPC POPS A BIT HIGH FOR SOUTHERN COUNTIES... BUT HARD TO RULE OUT 20 POPS THERE. NEW 12Z GFS HAS UPPER TROF STRONGER MOVING OFF NEW ENGLAND DAY 6 AND 7...WHICH WOULD DRIVE FRONTAL ZONE...FURTHER S ON FRIDAY. TOO EARLY TO JUMP ON THAT ONE SOLUTION. && .AVIATION /19Z FRIDAY THROUGH WEDNESDAY/... MVFR HZ LIFTS TO VFR VIS BRIEFLY THIS EVNG BEFORE FALLING BACK TO MVFR DURING THE OVERNIGHT HRS. ONLY PLACE WHICH WILL SEE IFR OR WORSE CONDITIONS WILL BE EKN. VIS BTW 5-6SM WILL COMMON THE LAST SIX HOURS OF THE FCST. AVIATION OUTLOOK STARTING AT 18Z SAT THROUGH WEDNESDAY...IFR/LIFR MORNING FOG AT EKN GIVES WAY TO HAZE EACH DAY. THE BEST CHANCE FOR THUNDERSTORMS IS SUNDAY. && .EQUIPMENT... SEE CRWFTMRLX. NWS TECHNICIANS WORKING ON RADAR. RADAR REMAINS DOWN AS OF 1950Z. && .RLX WATCHES/WARNINGS/ADVISORIES... WV...NONE. OH...NONE. KY...NONE. VA...NONE. && SYNOPSIS...29 NEAR TERM...29 SHORT TERM...KTB LONG TERM...KTB AVIATION...29 EQUIPMENT...KTB
