The episode as NWS PUB wrote it up.
An upper-level pattern which allowed for a sufficient mid-level monsoonal moisture plume to be established over the region aided in the development of storms, which produced heavy rainfall and lead to some heavy amounts of rain and minor flash flooding from the 7th thru 10th of August. A severe storm which developed over Teller County also allowed for a rare tornado to occur over high terrain, just NNE of Cripple Creek, on the 9th of August.

NWS Pueblo, CO wrote its last area forecast discussion before the first event at Aug 7, 1:48 PM MST, 14 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pueblo CO 248 PM MDT Wed Aug 7 2024 .KEY MESSAGES... - Widely scattered showers and thunderstorms will continue through the early morning hours, mainly over the southeastern plains. - Much cooler tomorrow, especially over the plains. Showers and thunderstorms will become numerous by the afternoon hours, mainly over the higher terrain. - Flash flooding will be a concern tomorrow, especially for the burn scar and urbanized areas which are prone to flooding. - A cooler, unsettled pattern continues into this weekend and early next week. - Flash flooding may become an increasing concern as more rain moves into the area, with showers and storms possible each day. && .SHORT TERM /THROUGH THURSDAY/... Issued at 247 PM MDT Wed Aug 7 2024 Tonight... Scattered showers and thunderstorms which have formed during the afternoon will continue well into the evening hours and possibly even into the morning hours over the southeastern plains, as some of the high res guidance is suggesting. Cooler temperatures will continue to advect in over the plains with the passage of a front this late afternoon through early evening, with increasing low cloud coverage across the plains becoming prevalent closer to sunrise. There will be some heavier showers possible, which may contribute to some localized areas of flash flooding by later this evening for the urbanized areas which are prone to flooding or for some locations where the soil is already saturated. Temperatures will gradually fall off into the low to mid 60s for a majority of the plains, and generally in the 40s and 50s for high country. Some clearing will take place over the mountains, although there could be a few isolated showers during the overnight hours as well. Tomorrow... With much cooler air advection in place and persistent northeasterly to easterly winds, and upslope flow, it will be notably much cooler tomorrow with temperatures well below the seasonal average for this time of year across the plains. The upslope enhancement will also help to trigger off some showers and possibly thunderstorms along the I-25 corridor by later in the afternoon, although the plains might be much too stable to allow for convection to continue to develop as these showers/storms move eastward. There will be a lot of moisture throughout the mid and upper levels. Due to this, showers and thunderstorms developing over the higher terrain will bring about the chance of very heavy rain and thus there could be flash flooding concerns, especially for the burn scar areas. As convection further develops in the afternoon and possibly moves over some of the urbanized areas which are prone to flooding, there could also be the potential of flash flooding concerns for these areas as well. For this reason, WPC has a slight risk of excessive flooding over a large portion of the CWA tomorrow, and marginal risk elsewhere. There will also be a fair amount of CAPE, over 2000 J/kg, over the eastern mountains during the afternoon hours, as well as effective bulk shear approaching 40 kts over some locations in vicinity of the Wet Mountains. Therefore a stronger or possibly severe thunderstorm cannot be ruled out. Main threat will be hail possibly up to an inch in diameter and gusty outflow winds up to 60 mph. These should weaken as they move out over the adjacent plains and into the I-25 corridor as the atmosphere will be considerably more stable. Highs will likely remain in the 70s across the plains, with values closer to the seasonal average but still cooler over the higher terrain. -Stewey && .LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/... Issued at 247 PM MDT Wed Aug 7 2024 A cooler and unsettled pattern will set in for the long-term forecast period, as the high pressure center in our region is shifted to the south with breezy northwest flow setting in over our area. Plenty of moisture will continue moving into our area, increasing chances for showers and thunderstorms throughout the day. Afternoon convection is expected to form over and near the higher terrain, before the northwest steering flow aloft pushes things onto the eastern plains. The main challenge with this part of the forecast will be coverage, intensity, and specific hazards related to storms. In addition to the ample moisture, models are moving an upper-level wave across our area on Friday, which should assist in stronger storm formation. The breezy northwest flow should also provide us with decent shear in the mid-late afternoon hours. The real determining factor will be instability. With the widespread moisture on Thursday, coupled with relatively cool temperatures, the plains may end up being a bit too stable for convective storms to actually fire and persist. High temperatures will only be in 70s to low-80s, so depending on the amount of forcing the passing wave provides, we may be too capped. What storms do manage to form, especially over the mountains, will be relatively fast-moving and capable of producing heavy rain. As of now, our main concern will be flash flooding in areas that get hit by multiple storms in quick succession. This general pattern of wet and cool conditions will continue this weekend and into next week. Northwest flow aloft will gradually give way to more westerly winds, with a series of shortwave disturbances passing overhead. Daily showers and storms will continue across the area through at least Monday, with increasing concern for flash flooding as soils become more and more saturated. The best chance for stronger storms will be closer to the CO-KS border, where instability will be a bit higher. High temperatures will range from the high-70s, low-80s over the mountain valleys, up to the high-80s, low-90s over the eastern plains through Monday. Moving further into next week, some upper ridging builds back in overhead, allowing high temperatures to warm back into the mid-90s over the plains. At the same time, some more shortwave disturbances are forecasted to pass through, continuing our daily chances for showers and storms. Flash flooding will continue to be a concern, depending on the amount of moisture our area receives throughout the next week. && .AVIATION /18Z TAFS THROUGH 18Z THURSDAY/... Issued at 1152 AM MDT Wed Aug 7 2024 VFR conditions are expected to prevail for KALS throughout the forecast period, and for KCOS and KPUB for most of the forecast period, although lowering CIGs and slightly reduced VIS in BR towards the end of the forecast period will bring about MVFR/IFR and possible IFR criteria, especially after 11Z at both sites. VCTS/VCSH will be likely by later in the day today at all stations, with low- med confidence of moving onstation. If SHRA/TSRA does occur and moves on station at either site, it could temporarily reduce CIGs and VIS to MVFR/IFR criteria. It could also result in periodic windshifts and increased wind speeds at all terminals. Winds will be synoptically influenced at all terminals, and increase out of the NW- NE at both KCOS and KPUB then becoming ESE towards the end of the forecast period. At KALS, winds will be out of the WNW, then come around to the NE-ESE, and eventually weaken to become L&V towards by late in the evening and through the rest of the forecast period. -Stewey && .PUB WATCHES/WARNINGS/ADVISORIES...

A few stronger storms may have wind gusts to 55 mph with small hail, but the main risks with storms today will be excessive rainfall and flash flooding. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday Showers and thunderstorms are expected every day over the mountains and the lower elevations throughout the forecast period. Thursday and Friday have the best chance for flash flooding over the mountains and over the urban population centers. As the week progresses saturated soils will become more widespread across the region so the chance for flash flooding will increase. Outside of flooding the main risks from these thunderstorms will be lightning and small hail. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible over portions of the region. STEWARD/GARBEROGLIO
