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 28, 11:46 PM MDT, 4 hours 18 minutes earlier.
Area forecast discussion, Jul 28, 11:46 PM MDT, 4 hours 18 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 1146 PM MDT Fri Jul 28 2017 .SHORT TERM...(This evening through Saturday) Issued at 305 PM MDT Fri Jul 28 2017 ...Increasing Monsoonal Activity through Tonight... After a relative down day yesterday, monsoonal activity is back on the upswing today. Storms firing over the mountains this afternoon have been pretty slow moving with pretty intense local rainfall rates according to some spotter reports. Also, some small, BB size hail was reported over the Wet Mountain Valley near Rosita earlier. The lack of steering flow and shear is evident in the atmosphere today. Storms are pulsing up fast to peak strength, then tending to weaken considerably as they drift off in varying directions at speeds less than 10 mph. The lack of shear is good in the sense that it will limit the severe potential. But, it is bad in the sense that storms will tend to sit over the same spot for too long of a period. Satellite derived Total Precipitable Water (TPW) values are still running well above average across the area, ranging from about 120 percent of average over northern parts of the forecast area up to about 160 percent of average over southern parts. And just as importantly, surface moisture remains high. Like they've been for days, dewpoints remain in the 60s across the plains, with 50s up into the high valleys. Moisture remains deep. Precipitation processes will remain efficient. Today's high resolution model runs are tending to favor the central and western mountains initially with less activity over the southernmost Sangres and plains. Then, unlike yesterday, through the afternoon and evening, they spread the activity east-southeast across the plains, eventually reaching the southeasternmost plains by mid to late evening. At the same time this is happening, the high res models want to keep at least some activity going on over the mountain areas through the evening hours, and then bring a new wave of energy north through the mountains around or after midnight. So, could be another night of persistent nocturnal convection. It's not supposed to happen too often in Colorado but seems to be happening a lot lately. .LONG TERM...(Saturday night through Friday) Issued at 305 PM MDT Fri Jul 28 2017 No big changes in current extended forecast, as quasi-stationary upper high across the southern high plains and into the Rockies keeps weak west to southwest flow aloft across the region through the weekend. Monsoonal moisture circling around the high maximizes across south central and southeast Colorado Saturday and Sunday with increased chances of afternoon and evening showers and storms expected across the all of area through the weekend. This will keep heavy rainfall and the potential for flash flooding high across the area, especially for areas over and near burn scars, and areas where previous heavy rains have saturated soils. The exact chances precipitation and bullseyes of heavy precipitation, especially over the eastern plains, will remain highly dependent on previous days convection, with models likely suffering from convective feedback issues throughout the extended portion of the forecast. At any rate, latest models indicating convection congealing into an mcs across the southeast plains Saturday night, which moves into southwestern Kansas through early Sunday morning. If this happens, it could be a down day of convection across eastern Colorado on Sunday. Either way, with expected wet weather, highs across the area through the weekend to remain below seasonal levels. Extended models continue to suggest the upper high slowly retrogrades back across the Desert SW and into the Great Basin region into the middle and through the end of the next week. This will lead to a slow warming and drying trend, especially across the eastern plains, as drier air slowly works into the region within more northerly flow aloft. && .AVIATION...(For the 06Z TAFS through 06Z Saturday night) Issued at 1146 PM MDT Fri Jul 28 2017 As the monsoon continues, the KALS, KCOS and KPUB will have the potential of experiencing showers and thunderstorms at times, the most intense of which will be capable of producing MVFR to IFR conditions at times during the next 24 hours. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. &&

The primary risks with thunderstorms will be locally heavy rainfall, wind gusts around 50 mph, hail around 1/2 inch in diameter and dangerous cloud to ground lightning. Localized flash flooding will be a threat for burn scars, urban areas and locations with saturated soil conditions. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Scattered to numerous afternoon and evening thunderstorms will be possible each day through Tuesday with thunderstorms persisting into the early morning hours across portions of the plains at times. The primary thunderstorm risks during this period will be heavy rainfall capable of producing flash flooding, lightning, small hail, and wind gusts up to 50 mph. One or two thunderstorms across the plains on Saturday could become severe with large hail and damaging wind gusts up to 60 mph possible. Thunderstorms will become less widespread and more confined to the mountains for Wednesday and Thursday. However, they will still carry the threat for heavy rainfall and localized flash flooding. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible tonight across south central and southeast Colorado.
