The radar
The Tulsa radar (KINX), 86 km from the middle of the area, began a volume at 16:45 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.
Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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
Norman, OK (KOUN), launched 12:00Z, 4.7 hours before the alert went out and 113 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.

$$What forecasters said that day
The local office's own words before this flash flood 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 flash flood warning went out at May 13, 11:06 AM CDT, 37 minutes earlier.
Area forecast discussion, May 13, 11:06 AM CDT, 37 minutes before
Area Forecast Discussion National Weather Service Tulsa OK 1106 AM CDT Fri May 13 2022 ...New SHORT TERM... .SHORT TERM... (The rest of today) Issued at 1106 AM CDT Fri May 13 2022 Updates to PoPs/thunder probs/temps etc made to the grids to account for overachieving band of elevated convection that continues to refire over central OK. Locally heavy rainfall has occurred with training storms this morning, necessitating some warnings. Assuming CAMs are even close to handling the current situation (big assumption), coverage of elevated convection should wane during the afternoon, though some isolated development is possible farther east into AR. Expect more updates to the forecast later. Focus then turns to the stalled front to our W and N for potential late afternoon/early evening strong to severe storm development. && .LONG TERM... (Tonight through Thursday) Issued at 352 AM CDT Fri May 13 2022 Additional thunderstorms will form late this afternoon across southern Kansas along an approaching cold front. These storms may move southeast into our area this evening with some severe weather threat before weakening during the overnight hours. Saturday looks quiet, with above normal temperatures continuing despite the cold frontal passage tonight. A few storms may drift southeast from the high plains into our area Saturday evening and overnight, but the chances appear low at this time. A better chance of showers and storms, possibly severe, will occur Sunday afternoon and evening as another cold front sweeps across the area. This frontal boundary will lift back north as a warm front late Monday into Tuesday, with a few showers and storms potentially developing to its north late Monday night into Tuesday morning. These would mainly affect parts of far northeast Oklahoma and far northwest Arkansas if they develop. Hot weather will be the rule for much of next week, with temperatures continuing to run several degrees above the seasonal averages. Rain chances will be very low after Tuesday. && .AVIATION... (12Z TAFS) Issued at 607 AM CDT Fri May 13 2022 Scattered showers and storms will affect E OK sites through mid morning before gradually dissipating. Cigs are expected to remain VFR through much of the period except for possibly in a heavier thunderstorm where lower vsbys will be likely as well. Later today and tonight, more showers and storms are expected to develop along a weak cold front with MVFR/IFR conditions possible within any thunderstorms. Otherwise, VFR conditions are expected with light winds for the remainder of the period. && .PRELIMINARY POINT TEMPS/POPS...
