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 12:00Z, 8.9 hours before the alert went out and 73 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 22, 2:55 PM EDT, 1 hour 59 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BLACKSBURG, VA 255 PM EDT TUE JUL 22 2003 SHORT RANGE (TNT-THU NIGHT)... MCS APPROACHING THE FA FROM THE TN AREA. QUESTION IS WHETHER TO GO CAT POPS EARLY...ESPECIALLY IN THE WEST. THE MCS IN GENERAL HAS BEEN WEAKENING...BUT THE LEADING EDGE HAS ACTUALLY STRENGTHENED IN THE PAST HOUR. POPS IS THE MAIN FORECAST DILEMMA FOR THIS PERIOD. LOOKING AT HIGH LIKELY POPS MOST AREAS TONIGHT...ESPECIALLY IN THE SOUTH...CLOSER TO INCOMING LIFT AND MCS. SFC FNT MOVES THROUGH MOST OF FA...LATE TONIGHT..BUT HANGS UP AS UPPER FLOW AMPLIFIES OVER THE ERN FA. COOL POOL ROTATES INTO THE FAR WRN CWA TOMORROW...WHILE DEEPER MOISTURE POOLS IN THE FAR ERN CWA. HAVE THE HIGHER POPS ON BOTH ENDS OF MY CWA...WITH A LOW CHANCE POP IN THE MIDDLE. DEEPER MOISTURE BEGINS LIFTING NE WED NIGHT...SO TAPER POPS OFF. KEEPING SLIGHT CHANCE THURSDAY...AS COLD POOL WILL BE OVERHEAD. LACK OF DEEP MSTR AND LIFT LEAVES ME TO BELIEVE THAT NOT ONLY ISOLATED TSRA TO DEVELOP...BUT POTENTIAL FOR A GOOD HAIL THREAT EXISTS WITH 5H TEMPS FALLING TO -12 TO -14. SHOULD BE DRY THURSDAY NIGHT WITH HIGH PRESSURE BUILDING IN...AND FRONT WASHES OUT TO OUR EAST. TEMPS TO REMAIN MILD TONIGHT. UPPED HIGHS TOMORROW SOME...AS THINK SOME SUN AND WEAK DOWNSLOPE MAY SEND TEMPS HIGHER THAN CURRENT FORECAST. LONG RANGE (FRI-TUE)... FRIDAY SHOULD BE DRY TROF PULLS OUT TO THE NORTHEAST SATURDAY...BUT A MEAN TROF REMAINS OVER THE EAST THROUGH THE EXTENDED PERIOD DESPITE HGHT RISES. NEXT FRONT TO LAY DOWN THROUGH THE AREA MON-TUE TIME FRAME. COULD SEE ENOUGH MOISTURE RETURN WITH REMNANTS OF MCS SUNDAY TO KEEP SLIGHT CHANCE GOING OVER THE WRN HIGHER TERRAIN...ESPECIALLY SE WV. MON-TUE WILL KEEP CHANCE POPS IN...HIGHER IN THE SOUTH TUESDAY AS FRONT STALLS OVER SRN VA. .RNK... NC...NONE. VA...NONE. WV...NONE. WHP
