The episode as NWS PUB wrote it up.
Another active period across southern Colorado on this day, with showers and thunderstorms observed over much of the area. The eastern mountain and I-25 corridor interface was a location with more widespread development, especially along the Highway 50 corridor. In this area, heavy rainfall with flooding, large hail, and damaging winds were observed.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area Forecast Discussion National Weather Service Pueblo CO 1119 AM MDT Sun Jul 25 2021 .SHORT TERM...(Today and tonight) Issued at 441 AM MDT Sun Jul 25 2021 Weak upper wave, evident in water vapor satellite loop, was lifting northward through the eastern plains of Colorado this morning, providing just enough lift the past few hours for small area of showers/thunderstorms east of I-25. Precip has faded to mainly sprinkles as of 0930z, while back over the mountains, a few light showers were lingering over the peaks as moist air mass remains in place. Weather pattern for today looks similar to yesterday, with weak flow aloft across CO while remnants of the mid level moisture plume remain overhead. Suspect subsidence behind northward moving wave on the plains may delay the onset of convection from the I-25 corridor eastward this afternoon, with better chances for storms from late in the day into the evening. Over the mountains, not much in the way of mid/upper level features to force convection, and while most CAMs suggest fairly widespread storms, they don't point to any particular area for heavy rainfall. As a result, will hold off on issuing any flash flood watches for this morning and let day shift look for any clues as to where heavy rainfall may occur today. Certainly still at least a low risk for heavy rainfall and flash flooding if the wrong storm moves over the wrong place, as precipitable water is nearly the same as yesterday. Guidance numbers for max temps drift down a couple degf today, though areas around Colorado Springs and Pueblo should end up warmer than yesterday's cloud/precip influenced readings. Tonight, convection again slowly diminishes through the evening, with a few showers lingering past midnight over the mountains and perhaps near the KS border where air mass is slightly more unstable. Min temps look little changed from the past few nights as clouds slowly clear by early Mon morning. .LONG TERM...(Monday through Saturday) Issued at 441 AM MDT Sun Jul 25 2021 ...A Slow Drying and Warming Trend through the Work Week... Upper level high pressure looks to build north and east of the region through the middle of next week, with the center of the high progged to be across the central High Plains by Wednesday afternoon. This will tend to slowly push the monsoonal moisture plume north and west of the area within weak eastern mid level flow by the middle of next week. Latest models then continue to suggest the plume slowly moving back into the region within weak west to northwest mid level flow next weekend, as the upper high continues to push south and west into the southern High Plains next weekend. On Monday, PWATS (1 to 1.5 inches) are progged to remain high across the region, with latest models continuing to indicate a surface boundary along the southeastern Colorado/northeastern New Mexico border. With moisture in place, should see convection start to fire across the higher terrain through the late morning and afternoon, with a better chance of storms along said boundary south of the Highway 50 Corridor across the plains, with storms slowly moving to west with the weak easterly steering flow. With the ample moisture and weak flow aloft, main storm threats will continue to be heavy rainfall, along with lightning and gusty outflows, with small hail possible with the stronger storms. Temperatures on Monday look to be near seasonal levels, with highs in the mid 80s to mid 90s across the plains, and mainly in the 60s and 70s across the higher terrain. For Tuesday through Friday, the high continues to drift into the central and southern High Plains, leading to a warming and drying trend, especially across the eastern Plains, as the main monsoonal moisture plume continues to shunted to north and west of the region. There will continue to be enough residual moisture to work with strong summer solar heating for scattered afternoon and evening showers and storms over and near the higher terrain. However, the thinning of the moisture will slowly lessen the heavy rain and flash flooding threat through the end of the work week. With less expected convection, especially over the plains, temperatures are expected to warm to above seasonal levels, with highs back in the 90s to around the century mark across the plains, with 70s and 80s across the higher terrain, save for 50s and 60s at the peaks. Slowly increasing chances of showers and storms can be expected across the region through next weekend, as available moisture begins to increase once again. && .AVIATION...(For the 18Z TAFS through 18Z Monday afternoon) Issued at 1113 AM MDT Sun Jul 25 2021 VFR at all TAF sites except possibly during thunderstorms. Thunderstorms will be possible during the afternoon and into the evening at the TAF sites. Very weak forcing makes it difficult to pinpoint timing and exact location of convection. Outflow boundaries will be a major factor for storm location. Believe convection will develop by mid afternoon over the region and continue into the early evening. With ample moisture, can get lower ceilings and visibility with storms which could produce locally heavy rain. By mid evening, convection should end with VFR conditions. --PGW-- && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...PETERSEN LONG TERM...MW AVIATION...PGW

The main risk with storms today will again be locally heavy rainfall, which could produce flash flooding over recent burn scars and across areas which have received heavy rain over the past few days. A few stronger storms could also contain small hail, gusty winds up to 50 mph and frequent cloud to ground lightning. Storms will gradually weaken and dissipate during the evening, with most activity ending by midnight. .DAYS TWO THROUGH SEVEN...Monday through Saturday Scattered to numerous afternoon and evening thunderstorms will continue across the mountains on Monday, with a few storms possible along the I-25 corridor and across the eastern plains. Storms will be slow moving and capable of producing locally heavy rain, leading to enhanced flash flooding risks, especially for area burn scars. Other storm threats will include lightning and gusty outflow winds to around 50 mph, with small possible with the stronger storms. Storm coverage and intensity will begin to decrease from Tuesday through the remainder of the work week, as available moisture decreases across the region. There will be enough residual moisture to support isolated to scattered afternoon and evening storms each day, with the best coverage across the higher terrain. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible across all of south central and southeast Colorado this afternoon and evening. 06/RODRIGUEZ
