The episode as NWS PUB wrote it up.
A thunderstorm produced heavy rain and flash flooding in southwest Teller County. Another severe storm produced wind damage south of the Pueblo Resevoir. In addition lightning struck a house in southwest Colorado Springs.
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.
NWS Pueblo, CO wrote its last area forecast discussion before the first event at Aug 9, 2:20 PM MST, 2 hours 20 minutes earlier.
Area Forecast Discussion National Weather Service Pueblo CO 320 PM MDT Wed Aug 9 2017 .SHORT TERM...(This evening through Thursday) Issued at 320 PM MDT Wed Aug 9 2017 ...A Little Less Storm Coverage This Evening... A little less moisture covers the area this evening. Total Precipitable Water values estimated by satellite indicate generally 90-115 percent of average, down from 120-140 percent of average yesterday at this time. So this should decrease the overall storm coverage. However, there is still a shortwave making its way eastward across the Rockies that is triggering storms at this time. This shortwave will still manage to kick off some storms through the evening. High res models have things picking up during the evening, particularly over the Pikes Peak Region and plains, possibly staying active through late evening. And, because there is more heat and better shear today, a few of those cells could be on the strong to possibly severe side during the evening hours. The primary risks with most storms this evening will be locally heavy rain, wind gusts to around 50 mph and lightning. However, a couple of storms across the plains could produce quarters and 60 mph winds. Overnight into early Thursday, areas of low clouds and fog could develop over parts of the area, particularly through the lower Arkansas River Valley. For tomorrow, most of the day will be rather quiet with only isolated storm activity. However, late in the day, a boundary will drop south to near the Palmer Divide. This boundary will be the focus for potential severe weather into Thursday evening. The Storm Prediction Center currently has a large portion of the plains under a slight risk for severe weather Thursday. This makes perfect sense in light of the boundary that is expected to move through. .LONG TERM...(Thursday night through Wednesday) Issued at 320 PM MDT Wed Aug 9 2017 Thursday night-Friday night...Upper high across the Southern Rockies and into the Desert Southwest keeps west to northwest flow aloft across the region. Latest models continue to indicate an embedded shortwave translating across the Northern Rockies and into the Northern High Plains Thursday afternoon, which sends a cold front across the Eastern Plains of Colorado Thursday evening and night. With low level moisture pooling along and behind the front, the boundary will be a focus for convection through the evening. Models are indicating CAPES of 1000-1500 j/kg and shears in excess of 40 kts across the eastern plains, which would support the development of supercell thunderstorms, capable of producing large hail and damaging winds across much of the southeastern plains tomorrow evening. Models indicating storms congealing into an MCS across the far southeast plains late tomorrow night, which then continues into southwestern Kansas through early Friday morning. Will see moist upslope flow across the eastern Colorado through the day Friday, with morning stratus and patchy fog likely keeping the plains too stable through the afternoon. Further west, expecting another round of afternoon and evening storms to fire, with storms moving east southeast across the immediate adjacent plains through the late afternoon and evening, with a few possible showers surviving across the far southeast plains through the late evening. Will again have to watch for the potential for flash flooding on Friday, especially over and near area burn scars, with possible training of storms. Temperatures through this period will remain below seasonal levels. Saturday-Wedensday...Models continue to suggest the cool northwest flow pattern will persist into early next week, with several more embedded waves digging across the area. Pattern will remain favorable for daily convection, though hard to time features will likely play a role in determining where convection and the heaviest precipitation will occur. Temperatures look to slowly warm into early next week, though will generally remain below seasonal levels. && .AVIATION...(For the 00Z TAFS through 00Z Thursday evening) Issued at 320 PM MDT Wed Aug 9 2017 Convection will tend to be less widespread this evening than last evening as a little drier airmass covers the region. MVFR to LIFR CIGS and VSBYS will be possible through areas of precip. Primary storm threats will include heavy rain, wind gusts to around 50 mph, pea size hail and lightning. Overnight tonight into early Thursday, some areas of MVFR to LIFR CIGS and VSBYS could develop across the plains, particularly through the lower Arkansas River Valley. The KCOS, KPUB and KALS terminals could see storms at or near the terminals this evening. That threat could linger until around 3 or 4 UTC at KALS and to around 5 or 6 UTC at KCOS and KPUB. Low clouds and ceilings could possibly impact the KCOS and KPUB sites from roughly 9 to 15 UTC, although this is not certain. For tomorrow, storms will be pretty isolated for most of the day. However, late in the day, a boundary will approach the Palmer Divide from the north and then move south through the plains. This will lead to much more widespread storm coverage across the plains into Thursday evening. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...LW LONG TERM...MW AVIATION...LW

Due to a slightly drier airmass over the region today, the most intense and widespread activity across southern Colorado will likely hold off until late in the day into the evening. The primary risks with most storms today will be heavy rain, wind gusts to around 50 mph, pea size hail and lightning. Flash flooding will be possible, particularly on burn scars and urban areas. One or two storms over the eastern plains could become severe late in the day, producing quarter size hail and wind gusts to around 60 mph. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday There will be daily chances of thunderstorms across the area through Tuesday, with the greatest coverage of storms expected to be over and near the higher terrain. The main threats from storms will be lightning and locally heavy rain, with the potential for flash flooding, especially across area burn scars. Small hail and gusty outflow winds will also be possible with a few of the stronger storms. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible this afternoon and evening across southeast and south central Colorado. 50/50
