The episode as NWS PUB wrote it up.
A slow moving thunderstorm moved across portions of the northern Spring burn scar producing over 0.50 inches of rain within 30 minutes. Some local impacts were felt as roadways became water or debris covered.
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 3, 1:18 PM MST, 1 hour 42 minutes earlier.
Area Forecast Discussion National Weather Service Pueblo CO 218 PM MDT Sat Aug 3 2019 .SHORT TERM...(This evening through Sunday) Issued at 218 PM MDT Sat Aug 3 2019 Another day another chance for high country showers and thunderstorms to develop within the monsoonal moisture and slowly drift off towards the east. Light east-southeast surface flow across the plains towards the Front Range will allow for better low-level lifting to take place but we really don't see the flow becoming strong enough to produce deeper convection over the hills and high terrain. MUCAPE and deep layer shear aren't the strongest, generally less than 1000 J/kg and 20 knots respectively, so expect slower storm motion and mostly pulse convective modes. Hi-res guidance has been showing throughout the morning today an area of enhanced convection along the Palmer Divide starting by mid- afternoon and tapping into somewhat better instability and moisture pooling. Again, without a better forcing mechanism expect mostly pulse strong to possibly an isolated severe especially with DCAPE values over 1500 J/kg today. Burn scar flooding is another threat this afternoon and evening as the storm motions will be slow to the east-southeast. There was quite a bit of rain that fell across the northern part of the Spring burn scar last evening resulting in some flash flooding and debris flows. The same type of storms are expected this evening though in a more scattered nature and not as organized as we saw last night. That being said, Hayden Pass, Junkins, and Spring burn scar are all in play this evening with heavy monsoonal rains. With even less flow and more of a southerly component to the surface flow expecting better coverage in the higher terrain. There will be a sharp cut-off of rain versus no rain from the Front Range eastward. We may be a little high on our forecasted rain chances from the I-25 corridor eastward to the Arkansas Valley, the confidence is low on how far east outflows and localized low-level lift propagate though we do expect less eastward movement then in previous days. .LONG TERM...(Sunday night through Saturday) Issued at 218 PM MDT Sat Aug 3 2019 Sunday night and Monday: Monsoonal high pressure remains over the desert southwest, which will continue to advect moisture surges from the Pacific towards our mountains. The thunderstorms that developed during the day will continue until a little after midnight, but diurnal flow will stabilize the atmosphere, dissipating any thunderstorms lingering. Model derived data hints at QPF "bullseye" over the upper Arkansas River Valley, with the NAM resolving the Leadville vicinity getting heavy rain and the GFS resolving the Salida vicinity getting heavy rain. It is still uncertain where that thunderstorm will initiate, but there is certainty that heavy rain with fall over the Upper Arkansas River Valley. The lingering thunderstorms will increase the risk for flash flooding over the Spring, Junkins, and Hayden Pass burn scars during the evening hours. Low temperatures overnight will be right around seasonal, with values over the plains in the upper 50s to mid 60s, the mountain valleys in the upper 40s to low 50s, and the mountains in the upper 30s to low 40s. The monsoonal ridge will remain in the same area (desert southwest) as Sunday, with the main moisture plume centered over the Continental Divide. Scattered afternoon thunderstorms are once again anticipated over the mountains, with the most numerous thunderstorms over the Continental Divide. Daytime thunderstorms equate to the risk of flash flooding of the burn scars. The eastern plains are mostly stable, with the exception of the Palmer Divide and the rest of northern El Paso County. An isolated strong to severe storm may develop over the Palmer Divide during the evening hours as a cold front propagates from the north to south. If the front develops more quickly than anticipated the chance for a stronger storm increases, if the storm lags behind, then chances will decrease since it'll miss the peak instability. Bulk shear values in that region are around 30 to 40 kts, so the potential for a stronger storm is backed up by shear as well. High temperatures will remain right around average for this time of year, with values in the low to mid 90s over the plains, the low to mid 80s over the mountain valleys, and the upper 50s to 70s over the mountains. The cold front will bring moist air with it, which increase the nighttime temperatures compared to what the region has been experiencing recently. Tuesday through Saturday: The monsoonal ridge will remain located generally over general southwest region. Towards the later parts of the forecast period, the ridge will weaken in magnitude and propagate to the east. Thunderstorms should remain over the mountains on Tuesday afternoon, model resolved soundings resolve a warm nose from 700-600 hPa, capping the atmosphere. Daytime heating doesn't look to be warm enough to reach convective temperatures. Wednesday through Saturday look very similar, in regards to upper level pattern and precipitation. The ridge breaks and propagates to the southeast, allowing a more westerly flow aloft to form over southern Colorado. Daily shortwaves will propagate over aloft, causing widespread mountain and low elevation showers and thunderstorms. In order for the ridge to break, a low pressure system located north of Colorado needs to force it to the south, so these outcomes are dependent on the timing and how strong that low pressure center is. With all of this being said, there is flash flooding risk over the burn scars everyday during the afternoon and evening hours. Longer term models are resolving the ridge propagating to the southeast during the later period of this forecast package, therefore there is higher certainty in that more widespread thunderstorms will develop as the ridge breaks. && .AVIATION...(For the 00Z TAFS through 00Z Sunday evening) Issued at 218 PM MDT Sat Aug 3 2019 Today...Mostly VFR. Expecting to see a few high terrain showers and thunderstorms develop that may push eastward just enough to clip KCOS later this afternoon bringing lower conditions. KALS/KPUB have slightly lower confidence on direct impacts so we continue the VCTS wording. Medium confidence overall. Tonight - Sunday Morning...Mostly VFR. Could see some higher based showers at KALS late this evening as moisture remains across the region, but generally conditions will be drying out overnight tonight as we lose the better instability. Light and variable winds expected at our terminals overnight under mostly clear skies. Start to see better mixing by late morning as we pick up an east-southeast wind less than 10 knots. High confidence. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...HEAVENER LONG TERM...SKELLY AVIATION...HEAVENER
