The radar
The Altus AFB radar (KFDR), 106 km from the middle of the area, began a volume at 01:02 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 tornado 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
Amarillo Airport, TX (KAMA), launched 00:00Z, 1.0 hours before the alert went out and 166 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.

Area forecast discussion, Jul 5, 6:14 PM CDT, 1 hour 46 minutes before
Area Forecast Discussion National Weather Service Norman OK 614 PM CDT Wed Jul 5 2023 ...New AVIATION... .SHORT TERM... (This evening through Thursday) Issued at 234 PM CDT Wed Jul 5 2023 The complex of showers/storms in north central OK will continue to move across NE/E portions of the fa this afternoon. Isolated/scattered storm development along/near an outflow boundary across southern OK curving up into west central OK into the TX panhandle will remain possible the rest of this afternoon into maybe early evening. A few of these storms may become strong to severe with strong winds, hail, and locally heavy rain possible. The higher potential for severe storms will likely be overnight into Thursday morning. Models show storms developing to the NW of the fa this afternoon then congealing into an MCS that moves into the fa overnight. Meanwhile, llj is expected to strengthen a bit this evening which could aid in continued storm development in the eastern panhandles, maybe into NW OK, this evening which could eventually spread into the fa as well. What all this means is that one or more storm complexes along with additional storm development will likely affect parts of the fa overnight into Thursday morning with the most likely area for storms across northern and central portions of Oklahoma as the storms move ESE/SE across the area. Severe storms will be possible with damaging winds and locally heavy rain the primary concerns. Thunderstorms will remain possible Thursday afternoon/evening but this will be somewhat dependent on how things unfold tonight into tomorrow morning. With the rain and cloud cover, below average temperatures (highs in the 80s) are expected across at least the NE half or so of the fa. More like average temperatures are expected in SW parts of the fa with highs in the low to mid 90s. && .LONG TERM... (Thursday night through next Tuesday) Issued at 234 PM CDT Wed Jul 5 2023 With WNW/NW flow aloft continuing into early next week, models are showing the potential for MCS(s) affecting at least parts of the fa night/morning hours each day into early next week. There could also be some storm chances in the afternoon and evening hours of those days but will be highly dependent on what occurs during the night and morning hours. As for the next couple of days, models show an MCS developing in the High Plains and moving SE into the fa Thursday night into Friday morning with the highest potential in portions of northern and central OK. Severe storms will be possible with damaging winds and heavy rain the primary concern. As for Friday into Saturday, models show storms developing to the W and NW of the area then moving into the fa Friday night into Saturday. Severe storms will be possible during this time as well with the highest potential across northern OK. Below normal temperatures are expected to continue across the NE third to half of the area into early next week due to rain/cloud cover. Hotter (around to slightly above average) temperatures are expected in SW OK and western north TX where less rain and cloud cover is expected. && .AVIATION... (00Z TAFS) Issued at 612 PM CDT Wed Jul 5 2023 VFR/MVFR ceilings expected. A complex of thunderstorms is expected to move across the area overnight into Thursday morning. Strong, variable winds gusts will be possible with some of these storms. Outflow boundaries moving across the area will also cause wind shifts. && .PRELIMINARY POINT TEMPS/POPS...
