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, 10:08 PM MST, 1 hour 42 minutes earlier.

ROSE && .SHORT TERM...(THIS EVENING THROUGH MONDAY) ISSUED AT 248 PM MDT SUN AUG 9 2015 MONSOON PLUME EXTENDS ACROSS SOUTHEAST PORTIONS OF THE AREA WITH EAST TO NORTHEAST UPSLOPE FLOW ACROSS THE PLAINS. THIS HAS KEPT DEW POINTS IN THE 50S...WITH A MIX OF 30S AND 40S ACROSS THE MOUNTAIN AREAS AND NORTHERN I-25 CORRIDOR. CONVECTION THIS AFTERNOON IS FIRING OVER THE ELEVATED TERRAIN AND ALONG A BOUNDARY WHICH IS DROPPING THROUGH SOUTHEAST CO...THOUGH IT LOOKS LARGELY SUPPRESSED AS SE CO APPEARS TO BE ON THE BACK SIDE/SUBSIDENCE REGION OF A SHORTWAVE/MCV WHICH HAS PUSHED INTO WESTERN KS. DEW POINTS ARE STILL ANTICIPATED TO MIX OUT A LITTLE...BUT THERE SHOULD BE A GOOD 1000-1500 J/KG OF CAPE ACROSS THE SOUTHERN PORTIONS OF THE SOUTHEAST PLAINS THIS AFTERNOON AND EVENING...AND WITH DEEP LAYER SHEARS RUNNING AROUND 30-40 KTS...AN ISOLATED STRONG TO SEVERE THUNDERSTORM WILL BE POSSIBLE. MOST LIKELY AREA FOR THIS TO OCCUR WILL BE ACROSS LAS ANIMAS...BACA...AND PROWERS COUNTIES. MARGINALLY SEVERE HAIL AND WIND GUSTS TO AROUND 60 MPH WILL BE THE PRIMARY STORM THREATS. THUNDERSTORMS SHOULD DIMINISH WITH LOSS OF HEATING...THOUGH SHORT RANGE MODELS SUGGEST ANOTHER WAVE MAY COME OFF THE SOUTHEAST MOUNTAINS INTO THE PLAINS DURING THE LATE EVENING AND OVERNIGHT HOURS. THESE SHOULD BE WEAKER IN INTENSITY AND SHOULD MOVE EAST AND DIMINISH ACROSS SE CO BY EARLY MONDAY MORNING. BUILDING UPPER RIDGE WILL BRING A RESURGENCE OF THE MONSOON PLUME NORTHWARD INTO CO ON MONDAY. THIS WILL INCREASE THUNDERSTORM CHANCES ACROSS ALL OF THE DISTRICT AS PRECIPITABLE WATERS INCREASE. EAST UPSLOPE FLOW ACROSS THE PLAINS SHOULD KEEP DEW POINTS A LITTLE HIGHER ON MONDAY...AND WITH SOME SUBTLE SHORTWAVES EMBEDDED WITHIN THE FLOW...SHOULD SEE SCATTERED SHOWERS AND THUNDERSTORMS DEVELOP OVER THE MOUNTAINS BY AFTERNOON...AND ACROSS SOUTHEAST PLAINS DURING THE MID-LATE AFTERNOON. MODELS HIT THE SOUTHERN SANGRES AND RATON RIDGE REGION THE HARDEST WITH SOME HEALTHY QPF AMOUNTS. MAY HAVE TO MONITOR THIS AREA FOR AN INCREASED FLASH FLOOD POTENTIAL MONDAY AFTERNOON...ESPECIALLY ON BURN SCARS SUCH AS EAST PEAK. HOWEVER MODELS DIFFER WITH THE DETAILS ON THESE QPF AMOUNTS...WITH NAM12 SIGNIFICANTLY HEAVIER THAN GFS WITH QPF ACROSS LAS ANIMAS AND BACA COUNTIES. WILL LET ANOTHER MODEL RUN CYCLE OR TWO COME IN BEFORE DECIDING ON A FLASH FLOOD WATCH...BUT ITS POSSIBLE THAT LAS ANIMAS AND BACA COUNTIES MAY NEED ONE. OTHERWISE...TEMPERATURES SHOULD REMAIN MILD TONIGHT...WITH MAX TEMPS ON MONDAY REMAINING BELOW CLIMATOLOGY. -KT .LONG TERM...(MONDAY NIGHT THROUGH SUNDAY) ISSUED AT 248 PM MDT SUN AUG 9 2015 ...EXTENDED PERIOD FEATURES THE MONSOON PLUME INTO THE WEEKEND... MONDAY NIGHT...INTERESTING SCENARIO DEPICTED BY NAM AND HINTED AT BY GFS. ISOLATED TO SCATTERED SHOWERS AND STORMS ACROSS THE AREA THROUGHOUT MUCH OF THE NIGHT AS A SHORTWAVE ROTATES AROUND THE WESTERN SIDE OF THE RIDGE...BUT A PERSISTENT AND STRONG MCS SHOWN BY THE NAM ACROSS LAS ANIMAS AND BACA COUNTIES THROUGHOUT THE NIGHT. THE MCS GIVES SEVERAL INCHES OF RAIN TO THAT AREA...SO UPPED THE POPS DURING THE NIGHT. TUESDAY...THE GFS HINTS AT THE MCS IN THE MORNING...WHILE THE NAM YIELDS A FEW MORE INCHES OF RAIN TO EASTERN LAS ANIMAS AND BACA COUNTIES. OTHERWISE...A SHORTWAVE ACROSS WESTERN COLORADO MAY CONTINUE RAINFALL IN THE WEST THROUGH THE MORNING. THEN DIURNAL SHOWER AND STORMS GET GOING ACROSS THE REST OF THE AREA. HIGH TEMPERATURES SHOULD BE LOWER WITH THE RAIN AND CLOUD COVER...PERHAPS BELOW SEASONAL NORMS. CONVECTION AGAIN COULD PERSIST THROUGH THE OVERNIGHT HOURS INTO WEDNESDAY MORNING. WEDNESDAY THROUGH SUNDAY...THE UPPER RIDGE STAYS OVER THE ROCKIES THROUGH THE PERIOD. BOTH GFS AND EUROPEAN MODELS SHOW THE WESTERN TROUGH LIFTING NORTH AND MOVING THROUGH THE NORTHERN ROCKIES AND GREAT PLAINS THROUGH THE WEEKEND. DURING THE WEEK...OCCASIONAL SHORTWAVES CIRCLING THE UPPER RIDGE WILL ENHANCE THE DIURNAL CYCLE OF SHOWERS AND STORMS. TEMPERATURES WILL BE AT OR SLIGHTLY ABOVE SEASONAL NORMS. THROUGHOUT THE ENTIRE EXTENDED FORECAST PERIOD...THE POSSIBILITY FOR LOCALLY HEAVY RAIN WILL BE THERE...SO SLOW MOVING STORMS WILL BE MONITORED FOR FLASH FLOOD POTENTIAL...ESPECIALLY ACROSS THE NUMEROUS BURN SCARS. -TLM- && .AVIATION...(FOR THE 06Z TAFS THROUGH 06Z MONDAY NIGHT) ISSUED AT 1103 PM MDT SUN AUG 9 2015 MAIN CONCERN IS POSSIBILITY OF TS FOR THE TAF SITES OVER THE NEXT 24 HOURS...AS THE MONSOON REMAINS ACTIVE OVER OUR AREA. ISOLD TO SCT TS SHOULD WIND DOWN OVER THE NEXT 2-3 HOURS OVER THE I-25 CORRIDOR...BUT ABUNDANT MOISTURE WILL KEEP A LOW GRADE THREAT OF STORMS GOING THROUGH THE MORNING HOURS. ANOTHER ROUND OF SCT STORMS IS EXPECTED AFTER 18Z ON MONDAY...AS CONVECTION MOVES OFF THE MTS AND ONTO THE PLAINS DURING THE AFTERNOON AND CONTINUING INTO MON MORNING. THE MAIN THREATS FROM STORMS WILL BE LOCALLY HEAVY RAINFALL WHICH COULD RESULT IN BRIEF MVFR-IFR CONDITIONS...ALONG WITH SOME LOCALIZED GUSTY WINDS. ROSE && .PUB WATCHES/WARNINGS/ADVISORIES...

28The Pueblo radar (KPUX), 58 km away, was scanning. The volume nearest the first event began at 06:51 UTC.
4 hail, 3 flash flood. Local standard time, as filed.
Torrential rain caused flooding of roadways and low spots across central and southern El Paso County. Up to 4 inches of rain was recorded east of Colorado Springs around Ellicott, and a report of over 7 inches of rain was received from the Hanover area, south-southeast of Fountain.
A slow moving thunderstorm brought very heavy rain and prodigious amounts of hail to western and northern parts of Colorado Springs and the Waldo Canyon burn scar. In the burn scar, Williams Canyon and the South Douglas Creek watersheds received the most rainfall. Williams Creek overflowed the channel in northern Manitou Springs, causing water to flow down Canon Avenue into the center of town, flooding a few houses and businesses. Meantime...the Autism Center in the South Douglas Creek watershed sustained major damage when water and debris flowed into the building after a retention pond west of Colorado Springs overtopped. In addition, a large volume of hail clogged street drains and caused flooding of streets across northern Colorado Springs. The hardest hit area was just east of the burn scar near Garden of the Gods Road. There were no known injuries with the flooding.
Heavy rain occurred across southwest Pueblo, causing water over 6 inches deep on many city streets, including Pueblo Blvd.
