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
Albuquerq/Krtlnd, NM (KABQ), launched 00:00Z, 0.6 hours before the alert went out and 331 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 National Weather Service Pueblo CO 527 PM MDT Wed Aug 26 2026 .KEY MESSAGES... - Shower and storms will continue into this evening. Flash flooding concerns continue over the Aspen Acres. - Strong to severe storms possible over the plains into this evening. - Showers and thunderstorms continue on Thursday, with warmer and drier conditions Fri/Sat. - Moisture looks to increase late this weekend and into next week. && .SHORT TERM /THROUGH THURSDAY/... Issued at 1242 PM MDT Wed Aug 26 2026 Another round of afternoon showers and storms will move through the area this afternoon and into this evening. Convection will continue forming over and near the higher terrain, pushing east-southeast. Latest observations and analysis show a window of high instability (1500+ J/kg of CAPE) over the eastern plains, and though there is some capping present, diurnal heating and some lift from a passing disturbance aloft should be enough to break through. The main impact concerns through this evening will largely be heavy rainfall and subsequent flash flooding over the burn scars. Further east, storms will increase in both strength and coverage as they encounter more moisture and better shear, bringing on the threat for large hail and gusty outflow winds as well. Lingering convection will move off into Kansas later tonight, and barring any outflow interactions, we should dry out into early Thursday morning. Tomorrow will be, overall, pretty similar to today, if a few degrees warmer. Models indicate a bit higher instability present over the mountains, with less moisture and instability over the eastern plains. Activity out east will be a bit more isolated in nature, while another day of flash flood risks will be in play for our burn scars. We may also see a strong to marginally severe storm around the Pikes Peak Region, where the more moist air will be influenced by the topography of the Palmer Divide thanks to northwest flow aloft. && .LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/... Issued at 1242 PM MDT Wed Aug 26 2026 The upper ridge will amplify over the region on Friday and Saturday, with the center of the high pressure settling just south of Colorado. This will give us a brief period of warmer and slightly drier conditions. High temperatures will be in the mid-high 90s out east, with some portions of the eastern plains exceeding 100 degrees on Saturday. The monsoon plume will be moved out of our immediate area, but lingering moisture at the mid to low-levels, combined with diurnal heating, will still allow for isolated to scattered convection each afternoon over the mountains. On Sunday, the ridge will shift east as an upper low moves onshore from the Pacific Northwest, bringing a new surge of moisture into our area. Daily showers/storms will increase in strength and coverage over the mountains, with more storms moving over the eastern plains as well. Cooler air will move in behind a cold front sometime on Monday, with temperatures settling back around seasonal normals. && .AVIATION /00Z TAFS THROUGH 00Z THURSDAY/... Issued at 526 PM MDT Wed Aug 26 2026 Mainly VFR conditions expected at COS, PUB and ALS over the next 24 hours. Scattered showers and storms thunderstorms pushing off the higher terrain and across the immediate adjacent plains will keep chances of brief MVFR conditions and gusty outflow winds at the terminals through 02Z. Skies partially clear overnight with generally light diurnal wind regimes expected through the rest of the taf period. With the available moisture in place, there is a low chance of seeing MVFR/IFR cigs at COS and PUB aft 10Z, however, too low of a chance to include in the taf attm. Also, with more northerly flow across the region tomorrow, convecton may be tied more to the higher terrain, and will not mention storms in the tafs at this time. && .PUB WATCHES/WARNINGS/ADVISORIES... Flash Flood Watch until 9 PM MDT this evening for COZ079-080- 086. Flash Flood Watch from Thursday afternoon through Thursday evening for COZ079-080-086. && SHORT TERM...GARBEROGLIO LONG TERM...MW AVIATION...GARBEROGLIO

The main hazard from storms again today will be locally heavy rainfall and flash flooding, with areas over and near the Aspen Acres burn scar continuing to be susceptible to flooding and debris flows. A few storms over the plains east of I-25 may become severe late in the afternoon and into the evening, with winds over 60 mph and half dollar sized hail possible. Many storms today and this evening may also produce gusty winds of 50 to 60 mph, frequent cloud to ground lightning and small hail .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Scattered to numerous showers and thunderstorms are possible each afternoon and evening through the period, with the greatest coverage of storms on Thursday. Locally heavy rainfall will again be the main hazard from storms each day, with a flash flood risk continuing for the Aspen Acres burn scar, especially on Thursday. Storms will also produce frequent cloud to ground lightning, gusty winds to 55 mph and small hail. .SPOTTER INFORMATION STATEMENT...
