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.
The nearest sounding before it
Tuscon, AZ (KTUS), launched 12:00Z, 10.6 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 severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Tucson, AZ wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 24, 2:00 PM MST, 1 hour 36 minutes earlier.
Area forecast discussion, Jul 24, 2:00 PM MST, 1 hour 36 minutes before
Area Forecast Discussion National Weather Service Tucson AZ 200 PM MST Sun Jul 24 2022 .SYNOPSIS...Deeper moisture and a favorable weather pattern will result in more widespread rainfall through this coming work week. This wetter period could result in flooding and flash flooding across the area the next few days. && .DISCUSSION...Thunderstorms managed to redevelop late this morning with most of the activity already producing heavy rainfall across parts of southwest Cochise and eastern Santa Cruz counties. As another disturbance approaches from the east, additional showers and thunderstorms will form across SE AZ through late tonight. A wet flow pattern will remain in place this coming work week with day-to- day fluctuations in the areal coverage of thunderstorms expected. Heavy rainfall will continue to be the main concern with elevated flows in normally dry washes and small streams. After a few days of rain, some of the larger washes could experience significant flows by the end of the week. The rain chances will be enhanced and sustained as an upper low/inverted trough currently positioned over the southern tip of Texas approaches the area on Monday. Latest models keep some form of this feature nearby through Wednesday before tracking farther west of the Baja California Peninsula by early Thursday. That said, a flash flood watch remains in effect for all of SE AZ through late Tuesday and may need to be extended to include Tuesday night and Wednesday. Otherwise, cloudiness and more widespread rainfall will help keep daytime temperatures closer to or slightly below seasonable readings. && .AVIATION...Valid through 26/00Z. Isolated to Scattered TSRA. Localized +TSRA likely. Lower cigs between 4-7k ft AGL can be expected around precipitation, including gusty winds in excess of 40 kts. Otherwise, cloud bases range 8-12k ft AGL with diurnal sfc winds generally less than 12 kts. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Deeper moisture in place will bring more widespread showers and thunderstorms, providing a greater potential for heavy rainfall. Most locations should see at least a wetting rain into next week, with many locations seeing areal averages greater than one half inch. Strong and erratic outflow winds accompany the stronger storms, with otherwise diurnal wind trends. && .TWC WATCHES/WARNINGS/ADVISORIES... Flood Watch through Tuesday afternoon for AZZ501>515. && Visit us on Facebook...Twitter...YouTube...and at weather.gov/Tucson
