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
Midland Regional, TX (KMAF), launched 12:00Z, 5.3 hours before the alert went out and 51 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.

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 Midland/Odessa, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at May 21, 11:23 AM CDT, 52 minutes earlier.
Area forecast discussion, May 21, 11:23 AM CDT, 52 minutes before
Area Forecast Discussion National Weather Service Midland/Odessa TX 1123 AM CDT Sun May 21 2017 .AVIATION... 18Z TAF issuance. Showers and thunderstorms continue to affect portions of the area early this afternoon with -TS near FST currently. This is the only site with mention of TSRA through this afternoon but will continue to monitor radar trends and amend if needed. VFR to MVFR cigs should persist through this evening then flight conditions expected to deteriorate to IFR, if not lower. Otherwise, easterly winds will prevail today with a few gusts through the evening hours. && PREV DISCUSSION... /issued 330 AM CDT Sun May 21 2017/ DISCUSSION... Current radar is showing showers moving up from the southeast into the Permian Basin this morning. This activity, though continuing to spread northwest, should remain fairly weak and isolated. The greatest rainfall potential for today will be in the Big Bend where models are showing an upper disturbance moving out of Mexico potentially producing heavy rainfall from Presidio to Sanderson. This area has not seen much rain lately and can take quite a bit of rain, but locally heavy downpours could still create some flash flooding problems and this will be the greatest weather threat for today. Tomorrow a ridge builds over the west coast and northwesterly flow over the Rockies will send another disturbance into the area. Shear and instability will be enough to support severe thunderstorms with large hail in discrete supercells, and also a strong wind threat should the activity form an MCS. See more details in the SWODY2 from SPC. The trough will send a cold front into the CWA early Tuesday, pushing the rain east but keeping below normal temps through midweek. Things change Thursday when the ridge over the western U.S. flattens and moves east with westerly flow bringing much warmer temperatures. Highs Thursday will range from the mid 90s to 100s with weaker flow Friday and Saturday only providing a couple of degrees of relief. Hennig && .PRELIMINARY POINT TEMPS/POPS...
