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.

$$What 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 Tulsa, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 21, 3:34 PM CDT, 2 hours 1 minute earlier.
Area forecast discussion, Apr 21, 3:34 PM CDT, 2 hours 1 minute before
Area Forecast Discussion National Weather Service Tulsa OK 334 PM CDT Fri Apr 21 2017 .DISCUSSION... Repeated widespread convection through the day has suppressed the most unstable warm sector to extreme southeast Oklahoma and points southward. Further north, elevated instability has been maintained with steep mid level lapse rates associated with approached trough. Forcing will continue to strengthen in advance of the aforementioned wave with convection increasing currently across NE OK with this activity spreading eastward through the evening. While these storms are elevated, sufficient effective shear will support scattered strong to severe storms. Further south nearer the sfc boundary the potential for sfc based storms increases and any storms which can develop within this zone will pose a more significant severe weather risk. The passing of the wave this evening will mark the end to the stronger storm potential while lingering light precip may continue into Saturday especially north of Interstate 40. The widespread heaviest rains have also likely ended however the last round of precip will contain smaller cores of heavy rain. Given the rainfall that has already fall we will let the Flood Watch remain in place until it is clearer that the heavy rain potential has completely ended. Noticeably cooler temps Saturday with breezy north winds. Warm up begins Sunday with the next frontal passage late Tuesday into Wednesday. Moisture return in advance of this front is questionable however storm chances associated with this frontal passage may mark the next chance of severe weather. A more substantial warm sector and higher severe weather potential looks likely by late next week as an unsettled weather pattern develops across the Southern Plains. && .PRELIMINARY POINT TEMPS/POPS...
