The radar
The Goodland radar (KGLD), 124 km from the middle of the area, began a volume at 01:09 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 local office's own words before this tornado warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Denver/Boulder, CO wrote its last area forecast discussion before this tornado warning went out at May 26, 3:29 PM MDT, 3 hours 37 minutes earlier.
Area forecast discussion, May 26, 3:29 PM MDT, 3 hours 37 minutes before
Area Forecast Discussion National Weather Service Denver/Boulder CO 329 PM MDT Fri May 26 2023 .SHORT TERM...(This evening through Saturday) Issued at 328 PM MDT Fri May 26 2023 Current radar shows thunderstorms developing and progressing NNE across the urban corridor this afternoon. Many containing at least small hail and a few severe storms containing large hail around quarter size. As these storms move across the plains where the environment is moist and unstable (MLCAPE 1500+ J/kg). Marginal shear will support organized convection. Threats: large hail, up to golf ball size and as convection continues to grow upscale across the plains, damaging wind may become a threat as well (DCAPE 1000+ J/kg). This axis of multicell thunderstorms will moves east into this evening, exiting Colorado before midnight. In the moist, cooled post storm environment there is potential for fog/low stratus early Saturday morning, but should burn off by 8/9 AM. Saturday the upper trough pushes slightly further east towards Colorado. After remaining low clouds/fog burn off, temperatures warm nicely into the upper 70s to around 80 across the urban corridor and plains. Lee troughing develops over the plains with southerly flow off the Palmer Divide. Another piece of energy in the flow will move across and serve as optimal synoptic support for thunderstorm development. The axis of higher instability moves slightly eastward across the plains with MLCAPE 1000-1500 J/kg. Similarly the moist airmass with dewpoints in the 50s situates over the east plains. Expect afternoon chances for scattered showers and thunderstorms. Marginal shear (20-25 kts) will support organized clusters of storms, a few potentially being strong to severe over the plains. Large hail and gusty winds will be the main threats. .LONG TERM...(Saturday night through Friday) Issued at 328 PM MDT Fri May 26 2023 Once again storms will tracking east across the plains during Saturday evening. They will shift east of the state and/or dissipate by midnight. For Sunday, southwest flow aloft will continue as a trough digs south across the Pacific Northwest and California. Short wave ridging in the southwest flow aloft will bring subsidence and drier air for Sunday. This will result in fewer and weaker storms for Sunday. The far northeast plains may hang onto better moisture which could result in another round of stronger late afternoon and evening storms. Upper level low slowly digs southeast over California while the blocking pattern remains over the eastern portion of the country. As the low digs south expect ridging to prevail over the Central and Southern Rockies. Flow aloft will be weaker (less shear for storms). Surface low pressure will be near the Four Corners, which will keep a southeast low level flow over east Colorado. This southeast flow will keep enough moisture over the area for daily afternoon showers and storms for Monday and Tuesday. Due to the weak flow aloft, the storms should stay below severe limits. For Wednesday through Friday, the low/deep troughiness remains over southern California and the Desert Southwest while the blocking ridge continues to the east. Southwesterly flow aloft to continue. Flow aloft could turn more southerly depending how deep the low digs. This would increase moisture across the area. Also, flow aloft may increase, which could lead to a better chance for severe storms. Timing of the better day(s), is still uncertain this far out, but daily showers and thunderstorms are expected each day. As far as temperatures go, most days are expected to reach the mid to upper 70s over northeast Colorado. Should finally see some lower 80s come Monday, Tuesday, and possibly Wednesday when the ridging will be over the area. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 1159 AM MDT Fri May 26 2023 Light winds still at the terminals late this morning. SE flow will increase early this afternoon at APA and DEN with gusts 20-25 kts. Main impact for today with be the thunderstorms this afternoon. Still looking at the 20-02z timeframe for seeing any nearby or passing thunderstorm activity and their impacts. Lightning, hail, and gusty outflow winds may accompany the stronger to severe storms. A few higher brief gusts are also possible ( < 35kts). Stronger storms may be accompanied by periods of lowering ceilings/visibility. Can't rule out low stratus/fog developing again after 06z. This will depend on the environment post-storms, so there is still some uncertainty is the chances/timing. Similar Saturday with strong S/SSE winds developing at APA and DEN and afternoon scattered showers and thunderstorms. && .HYDROLOGY... Issued at 328 PM MDT Fri May 26 2023 For remainder of today, there will be a limited flood threat for burn area flash flooding. Moisture and instability are there; however, storm motions are sufficient. Scattered showers and thunderstorms expected Saturday afternoon. Higher moisture and instability develop further east on the plains. There is still a chance for activity over the high country/burn areas, capable of producing locally heavy rainfall. Storm motions aren't expected to be slow, but any organized storm over the burns will pose a threat. Limited threat Saturday. Scattered showers and thunderstorms are expected each day. Not seeing a day with organized heavier rainfall, so the flash flood threat for the burn areas will be limited each day. && .BOU WATCHES/WARNINGS/ADVISORIES...
