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 Cheyenne, WY wrote its last area forecast discussion before the first event at Aug 2, 1:07 PM MST, 2 hours 21 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Cheyenne WY 207 PM MDT Sat Aug 2 2025 .KEY MESSAGES... - There is a Slight Risk (Level 2 of 5) for severe weather Saturday afternoon and evening east of the Laramie Range. All modes of severe weather are possible: large hail, damaging winds, an isolated tornado or two (southern Panhandle), and flash flooding. - There is a Marginal to Slight Risk of severe weather for Sunday, mainly across western Nebraska. Primary hazards look to be large hail, damaging winds, and flash flooding. - Drier and warmer conditions return mid-week and continue through the weekend. && .SHORT TERM /THROUGH SUNDAY NIGHT/... Issued at 105 PM MDT Sat Aug 2 2025 Thunderstorms already firing off once again across the region this afternoon and the potential for severe weather remains yet again. Stout instability of 1500-2500 J/kg lies from around Cheyenne eastwards, while favorable SRH lies just outside of our region to the west of the NE Panhandle. Overall the environment looks conducive of some stronger to severe thunderstorms including large hail and damaging wind gusts, but unlike yesterday we're not seeing quite as widespread stout severe parameters and with much of this activity firing off in a scattered nature, congealing of storms into clusters will help to limit supercellular development. The best region in our CWA for stronger severe weather development will be the Southern NE Panhandle, where a watch is possible in the coming hour or two. Meanwhile mesoanalysis also shows PWAT values of 1+ inch more into central Nebraska. This has helped to pull the Panhandle just out of the marginal risk of heavy rainfall, but some localized flooding can't be ruled out despite our downturn of flash flooding threat. CAMs indicate activity will either begin to weaken or move out of region during the early evening hours. Overnight more clearing should occur, and with downsloping expected low stratus and fog should finally not be an issue for the Nebraska Panhandle. Into tomorrow the Nebraska Panhandle remains in a Marginal (1 out of 5) risk for severe weather including hail and winds yet again. CAMs struggle to produce meaningful storms in Wyoming as moisture and instability continue to shift eastwards further into Nebraska. MUCAPE values of 750-1000 J/kg should still be present in the NE Panhandle and with bulk shear values a bit stronger in the 50-60 knot range, there should be at least meager support for a stronger storm or two during the afternoon. Meanwhile a drier surface layer may support some sounding profiles supportive of gusty showers or storms in Wyoming. Overall this weekend is thankfully looking quieter than our end to the week was, but a low end risk of some stronger to severe storms still can't be ruled out. && .LONG TERM /MONDAY THROUGH FRIDAY/... Issued at 105 PM MDT Sat Aug 2 2025 Warmer and drier weather is still expected in the long term forecast for Monday onwards. However, there is currently a Marginal Risk for severe weather across eastern portions of the region on Monday, due to northwesterly flow aloft allowing a weak disturbance to push through the flow and initiate enough synoptic lift via a stream of strong vorticity to support a few moderate to high based showers and possibly some isolated severe storms. Monsoonal moisture attempts to return the region as highlighted by NAEFS projecting Integrated Vapor Transport to be in the 99th percentile for the Intermountain west. The latest model soundings aren't too impressive and look to indicate wind as the main severe threat. Storm chances are expected to drop off Tuesday as an upper-level ridge builds over the southwestern CONUS and subsidence returns to southeast Wyoming and western Nebraska. PWATs are expected to be in the 10th percentile and gusty returning to the region to bring some Fire Weather concerns Tuesday. This high is expected to remain firmly in place, leading to more zonal flow across the region throughout the week. With the ridge so close by, its influence will be felt as temperatures once again rise into the 90s to near 100s. The warmest day looks to be Thursday at this time, though Wednesday through Friday will be quite hot. The next best chance for precipitation will be Saturday as an upper-level trough attempts to dive south out of Canada. However, this is still a week away, so things will change. This potential trough will continue to be monitored throughout future forecast updates. && .AVIATION /18Z TAFS THROUGH 18Z SUNDAY/... Issued at 1151 AM MDT Sat Aug 2 2025 VFR conditions expected to prevail over the next 24 hours. Another round of thunderstorms possible once again locally impacting both winds and visibilities as well as bringing MVFR or lower conditions for a brief period, with strong to severe activity primarily impacting Southern and Central Panhandle terminals this afternoon (KSNY, KBFF, KAIA) though all sites could see thunderstorms nearby. Cloud decks should be generally mid height, between 5-15k feet, but locally lower decks with storms also possible. Predominant winds 10-20 knots with some gusts to 30 knots possible, lessening overnight into tomorrow morning. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None.
