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
Pittsburgh, PA (KAGC), launched 12:00Z, 7.0 hours before the alert went out and 205 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, May 10, 2:51 PM EDT, 9 minutes before
Area Forecast Discussion National Weather Service Charleston WV 251 PM EDT Thu May 10 2018 .SYNOPSIS... Cold front exits this evening. Second cold front stalls over the area Friday through the weekend. Very warm weekend on tap. Continued warm but trending towards unsettled for next week. && .NEAR TERM /THROUGH FRIDAY/... As of 234 PM Thursday... Cold front evident in sfc obs with a wind shift and dewpoint gradient, along the OH River attm. This front will bring a cool air mass that could bring a relatively cool night tonight. Therefore, went with coldest guidance bias corrected MOS short for lows tonight. On Friday, a second cold front is expected to stall over our area through the weekend. Although do not see any shortwave to enhance instability, the location of the stalled front could serve as focus for convection due to diurnal heating and other any short wave not resolved by models. Therefore, kept chance PoPs for Friday. Used the blend of all models for high temperatures Friday. && .SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/... As of 250 PM Thursday... A frontal system will remain in the vicinity of our northern counties through the period. In addition, models suggest several weak shortwaves will race east in mainly zonal flow. The combination of these features should result in on and off chances of showers and thunderstorms generally across our northern counties. Southwest low-level winds should result in well above normal afternoon temperatures. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... As of 250 PM Thursday... The front should remain stationary near our northern counties through Tuesday before pushing north on Wednesday. Weak mid-level shortwaves will continue to traverse the area in quick zonal flow. Models suggest unsettled weather is expected to continue with the precipitation chances spreading south. Temperatures should remain above normal. && .AVIATION /19Z THURSDAY THROUGH TUESDAY/... As of 138 PM Thursday... Cold front crossing WV this afternoon producing isolated showers and thunderstorms along the eastern mountains. Brief periods of IFR visibilities possible along the heavier showers. Additional isolated convection is evident in radar images along the OH River. This convection could produce brief periods of IFR conditions as well as wind gusts up to 32 knots along their path. VFR conditions expected around sunset through at least midnight. After 06Z, conditions are ideal for fog development over river valleys and areas that received rain. Coded IFR conditions accordingly. Any fog may start to thin out across the middle Ohio Valley before dawn, as more clouds roll, in, from a warm front that may produce showers and thunderstorms near and beyond 12Z Friday. Southwest surface flow will switch to the west as the cold front crosses this afternoon, and then become light west tonight. Moderate to strong west to southwest flow aloft through today will become moderate northwest behind the cold front tonight. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z FRIDAY... FORECAST CONFIDENCE: Medium on timing and extent of showers today and fog tonight. ALTERNATE SCENARIOS: Direct impacts of showers and thunderstorms on the terminals may vary. Gusty winds will vary. Fog formation overnight tonight may vary.
