What forecasters said that day
The local office's own words before this flash flood watch went out, 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 this flash flood watch went out at Jul 25, 11:34 AM MDT, 2 hours 56 minutes earlier.
Area forecast discussion, Jul 25, 11:34 AM MDT, 2 hours 56 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 1134 AM MDT Sat Jul 25 2020 .SHORT TERM...(Today and tonight) Issued at 430 AM MDT Sat Jul 25 2020 Main forecast concerns/challenges continue to be with shower and thunderstorm chances today through this evening across much of the area, especially along and west of I-25. No real big change in the overall pattern this morning with south southwest flow remaining in place, and with a steady stream of moisture continuing to lift north across the region. At the surface, surface trough situated across eastern CO, with high dew point air in the 50s to low 60s in place. With these conditions in place, another relatively mild morning is expected, with temps then expected to rise to the 80s and 90s across the plains. Below normal temps expected over the mountain valleys, as thick cloud cover and periodic showers and storms will help limit daytime warming. Scattered showery development is occurring across the higher terrain this morning and expect this to continue, but do think energy and moisture helping to drive current showers and storms to the south will help bring an increase in coverage later this morning. By late morning/midday, will see daily increase in coverage and intensity of this precip, with thunder becoming more likely. Isolated to scattered showers and storms then possible across plains later this afternoon, especially along the I-25 corridor. Pattern similar to what was in place Friday is expected this afternoon, and think slightly higher focus will again be possible closer to the Palmer Divide. In this location, a slightly stronger storm will be possible. Tall and skinny CAPE is once again likely though, helping to limit the intensity of any storm today. Main hazards today will be lightning and occasional gusty winds, but do think there will be another risk for localized flash flooding. This will primarily be across the burn scars though, with all area burn scars at risk as early as midday. While the risk of flash flooding is expected today, have not issued a Flash Flood Watch at this time. Confidence is not that high yet, and also think Sunday and Monday could pose higher risks not only for the burn scars but for other portions of southern CO. By this evening, surface trough/boundary drop south across the area and think there could be some gusty northerly winds behind it, especially across the eastern plains. Thunderstorm chances will be on the decrease in the evening, however, do think showers will linger slightly longer into tonight. This trough/boundary will mark the beginning of additional increases in moisture, with high dew point air and high PWATs appearing likely late this weekend into early next week across much of southern CO. .LONG TERM...(Sunday through Friday) Issued at 430 AM MDT Sat Jul 25 2020 Sunday and Monday...Both days look to be the most active of the extended period, as the plume of monsoon moisture persists over New Mexico and Colorado. This moisture tap will fuel convection by midmorning over the higher terrain, with gradual storm movement to the northeast across the high valleys and I-25 corridor. At the same time, a cold front will be pushing into the eastern plains. Models suggest that the front will drop south of the Palmer Divide by noon, but then stall somewhat in the vicinity of Highway 50. This front will eventually push all the way south in the evening, but as this boundary wavers through the aftn it will serve as the focal area for storm development. So while storms will initially fire over the mts, convection is expected to linger well into the night across the eastern plains. Moving forward to Monday, after the front has pushed south into New Mexico, easterly surface winds will allow 60F dewpoints to push west up to the I-25 corridor, and another round of widespread showers and thunderstorms is forecast. Healthy QPF amounts both days suggest the potential for moderate to heavy rainfall rates at times, and if slow-moving storms develop and track across area burn scars, flash flooding is a significant concern. Look for max temps in the 70s both days for the high valleys. Across the plains, temps will climb into the 80s to near 90F on Sunday, then the 70s to around 80F for Monday. Tuesday...The upper ridge quickly moves west across the state while a disturbance crosses the Great Basin. There will be plenty of residual llvl moisture to once again fuel thunderstorm activity during the aftn and eve. However, surface winds are forecast to be more southerly so storms will likely be more tied to the higher terrain, temps will be slightly warmer, and convection should die off fairly quickly after sunset. Maximum temps will warm into the 70s for the high valleys, and 80s for the plains. Wednesday through Friday...The ridge restrengthens west of Colorado, with the ridge axis expected to be in the vicinity of Nevada and Utah. This positioning will produce drier and warmer conditions for the forecast area through the end of the work week. Expect isolated to scattered convection across the region each aftn and eve, with the best chances tied to the higher terrain. High temps will climb into the upper 70s to mid 80s for the high valleys, and mid 80s to mid 90s for the plains. Moore && .AVIATION...(For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1134 AM MDT Sat Jul 25 2020 At KALS, scattered showers and thunderstorms are expected near the terminal through around 12z. The best chance for a shower or storm to occur at the terminal is between about 21z and 02z, with gusty south to southwest winds during that time as well. Outside of the potential for lowered VIS with showers at the terminal, VFR conditions are anticipated for the next 24 hours. At KCOS, showers and thunderstorms are expected to develop over the nearby mountains early this afternoon and progress eastward. Nearby showers and storms are anticipated into tonight, with the best chance for a shower or storm to occur at the terminal being between about 21z and 01z. Winds are expected to shift to the north this evening and continuing through the rest of the period. Outside of the potential for lowered VIS with showers at the terminal, VFR conditions are anticipated for the next 24 hours. At KPUB, nearby scattered showers and thunderstorms are expected to develop this afternoon and last into tonight. Although chances are limited, an isolated shower or thunderstorm at the terminal cannot be completely ruled out this afternoon and evening. Gusty southwest winds are anticipated this afternoon before shifting to northerly winds. Winds gradually diminish overnight and become light and variable. VFR conditions are anticipated for the next 24 hours. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...RODRIGUEZ LONG TERM...MOORE AVIATION...CARLBERG

Locally heavy rain will be possible, and any heavy rain that falls over a recent burn scar will have the potential to cause flash flooding. A stronger storm or two is possible near the Palmer Divide late this afternoon through early evening, with the main hazards expected to be gusty winds and heavy downpours. A few storms will also be possible across the far eastern plains this afternoon and evening. .DAYS TWO THROUGH SEVEN...Sunday through Friday There will be daily chances of afternoon and evening thunderstorms across all of south central and southeast Colorado. Thunderstorms will initially develop by midmorning Sunday over the higher terrain, then activity will spread east across the plains as a cold front pushes south. Storm activity is expected to linger well into the night, then reignite on Monday across the mountains as well as the eastern plains. The best coverage of storms will be over and near the higher terrain through the afternoon hours Tuesday through Friday, with a few of the storms spreading east across the far southeast plains through the late afternoon and evening. Slow-moving thunderstorms will be capable of producing locally heavy rainfall Sunday through Tuesday, increasing the potential for flash flooding, especially across area burn scars. Other storm risks will be frequent cloud to ground lightning, with small hail and gusty outflow winds to around 45 mph possible with the strongest storms. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible this afternoon and evening over the mountains and near the Palmer Divide. 29/27
