CohenWhat forecasters said that day
The local office's own words before this severe thunderstorm warning 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 severe thunderstorm warning went out at Sep 3, 6:00 PM MDT, 3 hours 50 minutes earlier.
Area forecast discussion, Sep 3, 6:00 PM MDT, 3 hours 50 minutes before
Area Forecast Discussion National Weather Service Pueblo CO 600 PM MDT Fri Sep 3 2021 .MESOSCALE DISCUSSION... Issued at 559 PM MDT Fri Sep 3 2021 Main Forecast Concerns/Challenges: 1) We continue to monitor thunderstorm trends across El Paso County/I-25 corridor hear in the near term as well as over the eastern plains along the Highway 50 corridor later this evening into the overnight hours. 2) A quick summary: Thunderstorm development across El Paso county has stayed somewhat on the weaker side late this afternoon and this looks to continue to be the case over the next couple of hours. However, can't completely rule out an isolated stronger storm across El Paso county over the next 1-2 hours. 3) Concerns are increasing for more organized development around Pueblo and to the east across the Highway 50 corridor later this evening into the overnight hours. In this location and during that time, all hazards are possible including an increasing risk for heavy rainfall and flash flooding. Latest radar imagery continues to show persistent thunderstorm development across the Palmer Divide, where low level convergence and deep moist upslope flow are in place. An MLCAPE axis of 500 j/kg in this location along with steeper low and mid level lapse rates are supporting these thunderstorms. While instability, focus, and shear are in place, these storms have struggled to strengthen and maintain themselves though. Looking at RAP analysis and even more recent AMDAR soundings out of COS, there are some warmer temperatures aloft that are likely playing a big part in storm intensity at this time. Short term guidance/soundings have initialized fairly well with current conditions, and the forecast soundings over the next couple of hours show these warmer temps aloft maintaining themselves. So, think thunderstorm development will likely continue across the Pikes Peak region, Palmer Divide and into other areas of El Paso county over the next couple of hours but this development should stay subsevere. However, can't rule out a stronger storm producing small hail up to one half inch and wind gusts up to around 50 mph. Once again, concerns are increasing for more organized development around Pueblo and to the east over the plains later this evening and tonight. While conditions aren't appearing to come together right at this moment, latest trends and guidance are indicating this will change by mid evening. The mid level energy noted on latest WV imagery ejecting out ahead of a low amplitude mid/upper trough is expected to arrive over the next couple of hours. The arrival of this mid/upper forcing will help support lee troughing and a developing 700mb low across the eastern plains, with increases in 700mb and 850mb WAA as well as even some FGEN. The arrival of all of this increasing large scale ascent will of course support quickly developing thunderstorms but also support the erosion of the warm temps aloft. Instability develops across the plains as well as advects overhead this evening, while the resultant easterly flow supports strong and deep moist advection. So, expect additional thunderstorms to develop in the 8-10 pm time frame over the Pueblo county area and quite possibly southern El Paso county. During this time, developing MCS to the north is expected to dive south/southeast into the better instability with latest trends suggesting all of this merging into a larger complex of storms over the eastern plains/Highway 50 corridor late this evening into the overnight hours. Large hail to one inch is possible, though the previously mentioned warmer temps aloft may continue to help limit the extent of any hail tonight. A higher threat may be be damaging wind gusts possibly in the 60-70 mph range. However, even with this threat, there is still some uncertainty based on factors such as how long the overlap of forcing and instability will be and the time of night - likely increasing CIN. Additionally, surface trough axis and possible upstream outflow boundary could serve to increase the tornado threat later this evening, and will continue to closely monitor trends for this possibility. Lastly, the previously mentioned moist advection will likely bring mid to upper 60s surface dewpoints into eastern Colorado with short term guidance showing 850mb dewpoints of around 20c approaching the CO/KS border tonight. This increased moisture along with storm mode (east to west multicell and possibly training) will support an increased risk for heavy rainfall and flash flooding. One last item to note, is that this threat of severe storms and flash flooding could extend well into the overnight hours for areas over far eastern CO. && .SHORT TERM...(This evening through Saturday) Issued at 240 PM MDT Fri Sep 3 2021 Main Points: 1) Showers and thunderstorms are expected to increase in coverage later this afternoon and well into the overnight hours. 2) The Palmer Divide area will be seeing storms pass through, with gusty winds, locally heavy rainfall and small hail as potential threats. These storms should pop up in the next few hours and last until around midnight. 3) Strong to severe storms will be possible later this evening and tonight over the eastern plains, with the main threats being gusty winds, hail of 1-2 inches, and perhaps even an isolated tornado. Currently... Cloud cover over the CWA has broken up slightly compared to this morning, allowing for increased heating at the surface. A few showers have already popped up over both the Continental Divide and the far southeast plains, with no impactful weather reported as of yet. Just north of our area, past the Palmer Divide, several strong thunderstorms have already formed near the Denver Convergence Zone, with storm motion vaguely heading northeast. Today-Tomorrow... The tip of an upper-level trough is currently making its way eastward across Colorado, carrying with it enhanced lift and the majority of the forcing for enhanced precipitation. Showers have largely dwindled over the mountains and activity has steadily moved east throughout the day, although coverage is expected to increase overall as we progress later into the afternoon-evening hours, thanks to a healthy influx of mid-level moisture expected to circulate in around the upper-level high to our southeast. A weak surface boundary is also set up far to the southeast, intersecting portions of our southeast plains, which is assisting in giving us some easterly upslope flow over the plains. The slowly recovering, semi-stable air present in that area will also delay the onset of significant convection for a few hours yet at least, but once heating is able to overcome it and increase instability it may result in stronger storms this evening. Several short-term models have been consistently overmixing the boundary layer over our area, mixing out dewpoints by several degrees and limiting the extent of convection expected in our area. Given current moisture profiles over the plains, these models (including the HRRR) will have a bit less weight in the forecast for today and tonight, while the NAM seems to be handling things much better. Current analysis shows 500-1000 J/kg of CAPE over the Palmer Divide area, and between 1000-1500 over the far southeast plains. Around 30 knots of effective bulk shear are also present over the Palmer, with a considerable 45+ knots over the plains. Current dewpoints over the southeast plains are also currently sitting around the mid-60s. As of now, the main factor inhibiting thunderstorm development over the plains is the semi-stable air (and related CIN) sitting in that area. As daytime heating works to overcome it and continuously destabilize the environment, the main forcing will come later this evening as the axis of the upper trough passes overhead. As it does, that forcing is expected to spark thunderstorms along and near the boundary, assisted by easterly upslope flow increasing low-level convergence. With the CAPE and shear in place, as well as the ample moisture available in that area, we can expect a drastic increase in precipitation over the next 12 hours. To start, mostly moist, westerly flow aloft will assist in increasing shower coverage over the mountains later this afternoon, mainly over the San Juans, Sangres, and Continental Divide. As the trough axis moves more to the east, the main forcing will expand to cover the I-25 corridor, where upslope into our eastern mountains and the Palmer Divide will assist in sparking scattered to widespread showers and thunderstorms. As better forcing moves east and the plains become further destabilized, strong to severe thunderstorms will become possible later this evening into tonight. Given the available surface vorticity traveling along with the upper- level features, as well as the notable amounts of CAPE and shear available, gusty 60 mph winds and 1-2 inch hail will be well within the realms of possibility. Additionally, should an updraft manage to latch itself to the existing surface vorticity and maintain itself, cannot rule out the threat of an isolated tornado. Given the strength of the easterly winds expected over the plains, this threat could extend back to near the I-25 corridor, but is mainly confined to the southeast plains near the CO-KS border. Later tonight, storms are expected to continue, and as the upper trough moves east, storms are expected to move off of the Palmer and head southeast, where several short term models are actually resolving a larger system with potential QLCS properties moving across parts of the eastern plains before moving into Kansas by tomorrow morning. Showers are expected to persist into Saturday morning, although they should be more stratiform in nature. A cold front is expected to push south across the plains by late morning. Recent model trends have been consistent in keeping the front more robust, meaning that it will likely keep precipitation widespread over parts of the southeast plains and our southeast mountains. However, given the cooler, more stable air behind the front, thunderstorms, should any manage to form, will likely be much weaker than the storms we expect to see this evening. With post-frontal upslope flow expected to set in by early afternoon, main concerns for Saturday's weather will be storms firing over and near the Spring Burn Scar, with flash- flooding concerns on the table should a more convective storm manage to drop consistent rain. Otherwise, things tomorrow will be more stratiform, with overcast skies over much of the plains and cooler .LONG TERM...(Saturday night through Friday) Issued at 240 PM MDT Fri Sep 3 2021 Overall, there is great agreement through the extended between the operational solutions and ensembles. This leads to higher confidence in the extended period. Saturday night...an upper level trough is forecast to slowly move east into the Missouri Valley Saturday night, with trailing energy shifting south across Eastern Colorado. Moist, easterly upslope flow will be ongoing, with widespread precipitation from the Eastern Mountains, east along the New Mexico border. Weak instability may lead to a few thunderstorms over southern Sangre de Cristo and Raton Mesa areas. Locally heavy rainfall may be possible with stronger cores, which could produce a low risk of flash flooding on the Spring burn scar. This activity will shift south and east overnight, clearing to the southeast Sunday morning. Sunday through Thursday...high pressure will build over the Great Basin and slowly shift eastward during this period. This will keep dry conditions across southern Colorado for the Sunday afternoon, through Thursday time frame. A dry cold front will bring a continued cooler air mass to the area, with upper 80s to lower 90s across the Plains. Temperatures will gradually warm up by Thursday, with mid to upper 90s expected across the Plains. Friday...the upper level high will shift east into the Central Plains by Friday, with southwesterly flow returning to souther Colorado. Embedded energy could bring back showers and thunderstorms to the forecast along the Mountains. Mozley && .AVIATION...(For the 00Z TAFS through 00Z Saturday evening) Issued at 240 PM MDT Fri Sep 3 2021 KALS: VFR conditions expected over the next 24 hours. Winds will become gusty later this afternoon to about 20 mph before weakening again this evening. KCOS: VFR conditions generally expected through the next 24 hours. Isolated to scattered showers and thunderstorms are expected in the area, beginning after about 01Z and lasting through about 06Z tonight. Given the nature of the expected precipitation, it is still unclear whether anything will move directly over the terminal. If it does, expect brief periods of moderate to heavy rainfall and gusty erratic outflow winds. Will continue to closely monitor the area this afternoon and evening. Precipitation should move away from the area after midnight. After about 08Z tonight, there is a chance of some lower clouds developing over the terminal, but left with VFR conditions for now. KPUB: VFR conditions are expected over the next 24 hours. Isolated to scattered showers and thunderstorms will begin in the area around 23Z and increase in coverage throughout the evening and into the overnight hours. Direct impacts to the terminal are still expected to be low at this time, so left as VCSH. If a shower does manage to move over the terminal, brief periods of moderate to heavy rainfall and gusty erratic winds could be expected along with brief vis drops to MVFR. Rain is expected to clear out after about 09Z, where clouds will disperse and winds will weaken into tomorrow morning. && .PUB WATCHES/WARNINGS/ADVISORIES...

For this afternoon into the early evening, scattered thunderstorm development will be possible over the Interstate-25 corridor from Pueblo to the Colorado Springs area, along with areas farther west toward the eastern slopes of nearby mountains. This activity will spread generally eastward to southeastward, and will be capable of producing strong winds and hail. A couple of the most intense storms could produce quarter-size hail and 60-mph wind gusts. During the evening hours, thunderstorm activity will spread eastward and southeastward, toward and across the plains of southeast Colorado, potentially continuing through the pre-dawn hours Saturday morning. While not certain, this activity could increase in coverage and intensity during the late evening and overnight hours, and could become capable of producing widely scattered damaging winds, large hail, and possibly one or two tornadoes. The most intense storms are expected to occur along and north of a line from Avondale to La Junta to Lamar and Holly. In addition, there will be the potential for repeated rounds of heavy rainfall to occur late this evening into the overnight hours, especially along the U.S. Highway 50 corridor, and this could result in localized flash flooding. With a risk for severe thunderstorms extending well into the overnight hours tonight, interests across the southeast Colorado plains are encouraged to prepare ahead of time, to have multiple sources of being alerted to hazardous weather information. .DAYS TWO THROUGH SEVEN...Saturday through Thursday Scattered showers and thunderstorms are expected over the far eastern plains on Saturday morning and then over the I-25 corridor and the eastern mountains. The main hazards will be cloud-to -ground lightning and gusty winds, and there is a flash flooding chance over the Spring Burn Scar if a stronger storm were to develop over it. Isolated showers and thunderstorms are possible over the southern Sangre de Cristo Mountains, the Raton Mesa, and the Colorado- New Mexico-Oklahoma border. Gusty winds are the main hazard. Dry conditions are expected from Tuesday through Thursday. .SPOTTER INFORMATION STATEMENT... Weather conditions that meet reporting criteria for spotters will be possible across the Interstate-25 corridor from Pueblo to the Colorado Springs area, and locations eastward across the southeast Colorado plains, through tonight.
