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
Nashville Metro, TN (KBNA), launched 00:00Z, 1.7 hours before the alert went out and 117 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.

BarnwellWhat 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 Nashville, TN wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 26, 7:55 PM CDT, 47 minutes earlier.
Area forecast discussion, Jun 26, 7:55 PM CDT, 47 minutes before
Area Forecast Discussion National Weather Service Nashville TN 755 PM CDT Tue Jun 26 2018 .UPDATE... FOR EVENING DISCUSSION. && .DISCUSSION... Only a few weak storms remain in Middle Tennessee at the moment. A line of severe storms is currently moving across western Kentucky and may clip our northern zones. An even more widespread convective system over southern Illinois and southeast Missouri will likely affect the mid state afterwards, but the HRRR shows these storms dissipating rapidly as they enter Middle Tennessee later this evening. The 00Z sounding from OHX does show some instability in place (lifted index of -4, surface-based CAPE of 751 J/kg), but also the boundary layer has become stable owing to afternoon storms. Have lowered overnight lows on the Cumberland Plateau a few degrees since the rain-cooled air has already dropped early evening readings to or below previously forecast lows. Will keep scattered POP's in the forecast through the overnight period, tapering off further south. No other changes are planned for now. && .AVIATION... 00Z TAF DISCUSSION. Difficult forecast for this TAF period as rounds of showers and thunderstorms will be possible overnight and into the day Wednesday. Consensus has the evening TS more isolated, but another line of showers and storms looks to move in later this evening into the overnight hours from the northwest. Timing is hard to nail down with short term models having little agreement, so have VCTS mention for now. Should showers and storms impact terminals, periods of MVFR and even IFR vis will be possible with heavier rain. There looks to be a brief drier period just before sunrise, and another round of showers and isolated storms will move in mainly during the morning and early afternoon. Cigs look to remain VFR, with southeasterly winds around 10 knots becoming southwesterly by tomorrow afternoon. && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. && DISCUSSION......08 AVIATION........Barnwell
