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, 9.7 hours before the alert went out and 129 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.

.SHORT TERM (TONIGHT THROUGH FRIDAY)...
TONIGHT...AN UPPER LOW CUTS OFF OVER THE SAVANNAH BASIN AND DRIFTS
SLOWLY SOUTH WITH A WEAK INVERTED TROUGH AT 850 EXTENDING INTO THE
CENTRAL NC PIEDMONT.  MOIST AXIS WITH THE INVERTED TROUGH SHOULD BE
A FOCUS FOR SCATTERED SHOWERS AND POSSIBLE THUNDER MAINLY EARLY
TONIGHT...DECREASING AFTER MIDNIGHT.  HIGHEST CHANCE POPS WILL BE SW
TOWARD ANSON AND STANLY COUNTIES...LOWERING TO THE NE TO ONLY A
SLIGHT CHANCE OR LESS IN THE HALIFAX/EDGECOMBE COUNTY AREAS.
TEMPERATURE GUIDANCE FOR LOWS IN THE UPPER 50S TO AROUND 60 IS
FAVORED.

WED-THU...RIDGING TAKES HOLD ALOFT AS THE SAVANNAH BASIN LOW SETTLES
SOUTH AND WEAKENS.  SURFACE HIGH PRESSURE BUILDS IN THE TENNESSEE
VALLEY THAT BEGINS TO PUSH WINDS FROM THE WNW IN DOWNSLOPE FASHION
ACROSS THE AREA ON THU.  MID LEVEL MOISTURE REMAINS IN THE MIX TO
HELP GROW AFTERNOON CU EACH DAY...BUT DRYNESS IN THE LOWEST LAYERS
AND ALOFT SHOULD INHIBIT DEEP CONVECTION...THOUGH WITH ISOLATED
CELLS IN CONVERGENCE BOUNDARIES POSSIBLE.  AT THIS TIME...ITS
DIFFICULT TO FIND SURFACE CONVERGENCE BOUNDARIES WITH EACH MODEL
HAVING A DIFFERENT RENDITION.  DAYTIME MAXIMA SHOULD WARM FROM 81-86
WED TO 85-90 ON THU...ASSUMING CLOUDINESS REMAINS SCATTERED FOR MOST
OF THE DAY.  WED NIGHT LOWS MAINLY 60-65.

THU NGT-FRI...NAM IS MORE FORCEFUL THAN GFS IN PUSHING A BACK DOOR
COLD FRONT AND COOLER AIR INTO THE REGION BY FRIDAY.  BOTH SUGGEST A
FRONTAL RAIN BAND ACROSS THE AREA LATE THU-THU NIGHT WITH THE RAIN
THREAT CONTINUING INTO FRI ON THE GFS BUT DRYING OUT ON THE NAM.

UPPER RIDGING OVER THE EASTERN SEABOARD WILL SHIFT EAST EARLY THIS
WEEKEND. IN ADDITION...SURFACE HIGH PRESSURE WILL GRADUALLY SHIFT
OFFSHORE RESULTING IN MOIST RETURN FLOW WHICH WILL LINGER INTO
TUESDAY. THERE ARE FEW FORCING INDICATORS TO FOCUS PRECIPITATION
INITIALLY AND EXPECT SCATTERED DIURNAL CONVECTION SATURDAY. SHOWERS
AND TSTMS WILL BE A BIT MORE WIDESPREAD...STILL IN THE CHANCE POP
CATEGORY...DUE TO CONTINUED MOISTURE ADVECTION AND APPROACHING FRONT
SUNDAY AND MONDAY. WILL ALSO CONTINUE CHANCE POPS TUESDAY DUE TO
TIMING UNCERTAINTY. HIGHS MAINLY IN THE MID AND UPPER 70S THROUGH
THE PERIOD.
