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 May 31, 4:33 PM MST, 3 hours 14 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pueblo CO 533 PM MDT Sat May 31 2025 .KEY MESSAGES... - Scattered thunderstorms this evening, a few strong storms along the I-25 corridor. - Forecast repeats on Sunday, with afternoon/evening thunderstorms expected, and few strong storms again possible. - Cooler and wetter weather pattern on track for next week, with daily chances for showers/thunderstorms and temperatures much below seasonal averages Tuesday and Wednesday. && .SHORT TERM /THROUGH SUNDAY/... Issued at 141 PM MDT Sat May 31 2025 Another late start for convection this afternoon, with just isolated activity on radar as of 2 pm. Expect storms to expand and strengthen over the mountains through the remainder of the afternoon, then push eastward across the I-25 corridor starting 5-6 pm. CAPE around 1000 J/KG and 0-6km shear of 25 kts suggest a couple strong/low end severe storms possible, especially along I-25 this evening. Storms move onto the plains and dissipate this by late evening, persisting the longest over Las Animas/Baca Counties. On Sunday, upper ridge builds slightly across CO, but overall, weather pattern remains the same, with moisture/instability lingering and another round of afternoon/evening thunderstorms expected. Again, maybe a strong/brief severe storm possible along I-25 toward evening. Temps will remain warm, with maxes drifting upward a degf or two with building heights. && .LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/... Issued at 141 PM MDT Sat May 31 2025 Active weather week begins Monday, with old swrn U.S. upper low finally booted northeastward into CO during the day as new trough drops south along the Pacific Coast. With dynamic lift strengthening across the area, expect shower and thunderstorm coverage to increase, especially over the mountains along the Continental Divide. Scattered to numerous showers/storms are also expected across most interior valleys, while convection on the plains looks more isolated, as low/mid level flow takes on a more w-sw downslope component in the afternoon. Could be a risk of a severe storm over the far eastern plains along the weak surface trough/dryline, though low level moisture convergence looks rather weak, and most model solutions keep stronger storms well east in KS. Surface cold front then races south through the area Monday night, with post-frontal upslope and dynamic lift generating showers/thunderstorms through the night into Tuesday morning, especially along the I-25 corridor and across the eastern plains. In general, most model data has trended wetter across the area Monday night, as upper low appears to be slightly slower/stronger as it ejects across the region. Showers/isolated thunderstorms linger Tue/Tue evening, though air mass looks very cool and stable from the eastern mountains across the plains, which may limit convection. Slightly warmer Wed with afternoon/evening showers/storms, though again cool temps may limit convective strength, especially on the plains. Upper trough lingers over the western U.S. into next weekend, and with moisture not going anywhere, expect afternoon/evening convection to persist through the period. Temps will gradually warm back toward seasonal averages by the weekend, though no extreme heat is expected. && .AVIATION /00Z TAFS THROUGH 00Z MONDAY/... Issued at 533 PM MDT Sat May 31 2025 KALS: VFR conditions expected through 24 hours. Some showers may drift off of the mountain between now and 9pm or so, but currently no impacts are expected at the terminal. Will monitor for outflow or needed updates due to storm interactions. Winds lighten overnight, becoming a bit more breezy and southwesterly Sunday afternoon. KCOS and KPUB: Showers and storms will move through the area of both terminals. KCOS already has storms nearby, which should move through between 00-02Z. Will monitor for any leftover showers thereafter, but that should be it for anything strong. Some gusty outflow will be possible along with rainfall. KPUB will see passing showers and storms later on in the evening, with a lower chance of precipitation at the terminal. Left as PROB30 for now given the scattered nature of showers. Nearby showers will end by about 05Z, with light winds overnight turning westerly in the morning. Another round of showers and thunderstorms is expected late tomorrow afternoon into the evening, near both KCOS and KPUB. && .PUB WATCHES/WARNINGS/ADVISORIES...

Shower and thunderstorm activity will end by around midnight as storms move southeast into New Mexico .DAYS TWO THROUGH SEVEN...Sunday through Friday Daily rain showers and thunderstorms are still expected over the next several days. Showers and storms will be greatest in coverage along the higher terrain Sunday, and expand in coverage Monday through Friday. Greatest hazards from any thunderstorms are expected to be small hail, gusty outflow winds, heavy rainfall, and lightning. .SPOTTER INFORMATION STATEMENT...
