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
Santa Teresa, NM (KEPZ), launched 00:00Z, 0.8 hours before the alert went out and 336 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, Jun 25, 12:58 PM MST, 4 hours 50 minutes before
Area Forecast Discussion National Weather Service Tucson AZ 1258 PM MST Thu Jun 25 2026 .SYNOPSIS...Chance of thunderstorms from Tucson south and east this afternoon, slight chance Friday along the AZ/NM border, with dry conditions returning this weekend into next week. High temperatures will be 2-6 degrees above normal through Saturday then around normal Sunday into next week. Breezy southwest winds during the afternoon and evening Friday through Monday resulting in areas of critical fire weather conditions. && .DISCUSSION...Southwesterly flow aloft prevails this afternoon between the subtropical high centered over Chihuahua and weak troughing along the west coast. Latest visible satellite imagery along with KEMX radar shows clouds developing along with a few showers and thunderstorms across Graham/Greenlee/Cochise counties at this time. That is where the focus of the convection will be this afternoon as the combination of PWAT's around 1 to 1.2 inches and MLCAPE around 1000 J/KG support scattered thunderstorms. Coverage will be greater than yesterday afternoon, with Tucson being on the western edge of thunderstorm activity. The main threat for storms today will be gusty outflow winds of 40-50+ mph. The secondary threats will be flash flooding with any back-building/training storms (primarily for Cochise County) and hail with the strongest storms as 0-6km bulk shear around 20 kts will help support a few stronger updrafts. Most of the convection should weaken earlier this evening, though the CAMs do show potential for a complex along the Sonora/Chihuahua border well south of the Int'l border this evening and that can push some outflow into Cochise County later tonight. Outside of thunderstorms, heat is the main story with an Extreme Heat Warning in effect until 8 PM for portions of southeast Arizona. Our area will start to become more under the influence of stronger westerly flow aloft Friday as troughing builds down the west coast. There will still be enough residual moisture for isolated storms (10- 20 percent chance) near the AZ/NM border Friday afternoon. As southwest breezes increase Friday afternoon to around 15-20 mph with gusts around 30 mph, elevated to near critical fire weather conditions will return to much of the forecast area. High temperatures Friday will lower about 1 to 2 degrees compared to today. As an anomalously strong trough sets up on the west coast in an amplified pattern this weekend with the subtropical high over the lower Mississippi Valley, that will bring in a drier airmass for all of southeast Arizona along with a continuation of breezy to windy conditions this weekend. Southwest winds both Saturday and Sunday afternoon will be sustained around 15-25 mph with gusts 30-40 mph. The combination of these strong winds and dry conditions will result in critical fire weather conditions and a Red Flag Warning is in effect this weekend. Temperatures by Sunday will lower to near or even slightly below normal levels. Breezy conditions will continue Monday with elevated to locally near critical fire weather conditions. Thereafter, broad troughing and southwesterly flow through much of next week with temperatures near to slightly below normal. Looking for monsoon moisture, as the trough weakens late next week, the flow will become more southerly. Initially, any moisture will remain along the AZ/NM border around next Thursday and Friday. We'll have to see how things evolve for the July 4th weekend but hints of a more typical monsoon pattern with a Four Corners high developing around July 5th or just beyond. && .AVIATION... Valid through 27/00Z. SCT clouds at 12k-15k ft AGL and SCT-BKN AOA 20k ft AGL mainly from Tucson south and eastward thru 26/06Z and again aft 26/19Z. Isolated to scattered -SHRA/-TSRA from KTUS south and eastward will continue through roughly 26/04Z. The best chances will be in Cochise and Graham Counties including KDUG, with lower confidence in any storms impacting KTUS/KOLS terminals. Strong outflow winds 30-40 kts will be possible in the vicinity of storms. Otherwise SFC winds WLY-NWLY at 8-14 kts with ocnl gusts to 20-25 kts thru 26/03Z, becoming variable in direction at less than than 8 kts thereafter thru 26/16Z. Sfc winds increase again aft 26/16Z becoming SLY/SWLY at 10- 20 kts with gusts up to around 30 kts. Aviation discussion not updated for TAF amendments. && .FIRE WEATHER...Expect scattered showers and thunderstorms from Tucson south and eastward this afternoon and along the AZ/NM border Friday. Thunderstorms will be capable of wind gusts to 40+ mph. A bit of residual moisture for isolated storms along the AZ/NM border Friday afternoon, but otherwise drier conditions start to move in with minimum relative humidity levels in the 10-20 percent range. Areas along the international border will be on the higher end of that range. Southwest winds increase Friday afternoon as a weather system moves through to the north, and stay breezy through Monday. Saturday and Sunday continue to appear to be the breeziest days with some locations seeing Red Flag conditions in the afternoon and evening from Sells eastward. Southwest winds of 15-25 mph and gusts to 35-40 mph are expected Saturday and Sunday afternoon/evenings. Outside of the Red Flag period Saturday and Sunday, elevated fire weather conditions are expected Friday and Monday. Winds will be lower the middle of next week. Some monsoon moisture returns along the AZ/NM border late next week. && .TWC WATCHES/WARNINGS/ADVISORIES... Extreme Heat Warning until 8 PM MST this evening for AZZ504>507-509. Red Flag Warning from 10 AM Saturday to 8 PM MST Sunday for AZZ150>154. && Visit us on Facebook, X, YouTube, and at weather.gov/Tucson
