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.

$$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 Aug 31, 6:41 AM CDT, 20 minutes earlier.
Area forecast discussion, Aug 31, 6:41 AM CDT, 20 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 641 AM CDT Mon Aug 31 2020 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KBVO/KMLC/KXNA/KFYV/KFSM/KROG. Thunderstorms are ongoing across eastern Oklahoma and northwestern Arkansas at the time of writing. A strong to severe storm was moving into the vicinity of FSM. This storm will likely produce brief gusty winds as it passes over the terminal. Spotty showers and storms continue at most other terminals this morning. This activity should gradually diminish by mid to late morning with skies expected to clear. A brief period of clearing skies is expected for the first half of the afternoon. The afternoon and evening forecast for this TAF period remain very uncertain at this time. A cold front will approach the area from the west which will be the main trigger for thunderstorms this afternoon. There is also the potential for an outflow boundary originating from a storm complex near Kansas City that will dive into the area which may provide additional lifting for thunderstorms. The eventual setup up of these two fronts will play a vital role when it comes to the location and duration of storms this afternoon, evening, and overnight for the terminals. With low confidence, opted to go with guidance that would slowly push thunderstorms through all terminal sites this evening and overnight resulting in several hours of thunderstorms. The 18Z TAF issuance should have a better handle on what to expect this evening and overnight in terms of the duration of thunderstorm activity and when the lowest conditions could occur. As it stands now, TEMPO groups were used to illustrate where confidence was a little higher in terms of the lowest expected conditions from thunderstorms. Snider && .PREV DISCUSSION... /Issued 327 AM CDT Mon Aug 31 2020/ DISCUSSION... Widely scattered showers/thunderstorms starting to develop across NE OK in response to approaching upper wave in stronger low level jet axis. Moderate instability/fairly steep mid level lapse rates coupled with deep layer shear around 35 knots will support a large hail/damaging wind threat across portions of eastern Oklahoma this morning. In addition, with PWAT around 2 inches, locally heavy rainfall is likely in the stronger storms. This activity will begin to shift east into northwest Arkansas this morning and will likely begin to weaken as storms move into a more stable air- mass. Cold front will push into far northeast Oklahoma this afternoon with atmosphere becoming very unstable as low level moisture pools ahead of boundary with dew-points climbing in the upper 70s. Weak surface low progged along boundary may back winds enough for a limited tornado threat, however main threats will again be large hail/damaging winds. Thunderstorms are expected to increase in coverage through the evening hours with activity spreading into southeast Oklahoma/northwest Arkansas. With rainfall rates in the 1-2 inch per hour range in the stronger storms, localized flooding will be possible and a flash flood watch may be needed for some areas, especially south of I-44 where FFG has been lowered from the previous rainfall over the last few days. Multiple rounds of thunderstorms with a heavy rainfall will remain possible Tuesday into Wednesday as upper trough axis approaches from the northwest with upper low moving over the Four Corners region and into west Texas. More widespread flooding will be possible during this time including some main-stem river flooding. Depending on how quickly upper low progresses, precipitation chances may continue across southeast Oklahoma/northwest Arkansas Thursday with a few lingering showers into Friday across the south as front pushes south of the Red River. Cooler and less humid conditions expected over the weekend as weak surface ridge axis remains over NW AR. && .PRELIMINARY POINT TEMPS/POPS...

Additional severe thunderstorm development is expected across portions of northeast Oklahoma by late afternoon or early evening as a cold front moves into the area. This activity will likely spread into southeast Oklahoma and northwest Arkansas this evening into the overnight hours with large hail and damaging winds. In addition, very heavy rainfall is likely with localized flash flooding. A flash flood watch may be issued later today as the axis of heavy rainfall becomes more certain.
