NWS Cheyenne, WY wrote its last area forecast discussion before the first event at Aug 15, 4:08 PM MST, 16 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Cheyenne WY 508 PM MDT Fri Aug 15 2025 .KEY MESSAGES... - Isolated to widely scattered PM showers and thunderstorms will continue today and through the weekend with slightly cooler temperatures this weekend. - Hot and dry conditions return for the upcoming work week with only minimal precipitation chances. && .SHORT TERM /THROUGH SATURDAY NIGHT/... Issued at 219 PM MDT Fri Aug 15 2025 A deep trough impacting the Northwest has shifted the mid and upper level flow to the south/southwest pushing some weak energy northeast across the CWA, this coupled with winds generally shifting to the south is bringing in some low level moisture into southeast Wyoming and the Nebraska Panhandle. This will increase the shower and thunderstorm threat through the afternoon hours into the early evening. Due to modest severe weather parameters, the primary threat from these thunderstorms will be gusty winds in the 40 to 50 mph range. Dewpoints will be 40 to 45 degrees across southeast Wyoming and in the mid 50s across the Nebraska panhandle. With the thunderstorm threat, kept POP values between 30 to 50 percent across a good portion of the CWA. With the modest severe parameters in place, all this should justify the Marginal severe risk for this afternoon and early evening. Expect somewhat "cooler" temperatures today with highs topping out in the 80s and low 90s primarily west of the I-25 corridor and into the low to mid 90s across far eastern Wyoming and the Nebraska panhandle. Expect much of the same for Saturday, with another upper level disturbance pushing through the CWA. Model agreement has improved since earlier runs, showing similar placement and timing of the energy. Kept POPs generally between 30 to 50 percent range. Convective parameters once again are modest, with primarily a wind threat from any thunderstorm activity. Temperatures will continue a slight downward trend through Saturday, which will be one of the coolest days over the next week or so, with highs in the 80s to low 90s across most of the CWA. && .LONG TERM /SUNDAY THROUGH FRIDAY/... Issued at 219 PM MDT Fri Aug 15 2025 Starting Sunday the Intermountain West starts to dry out as an upper level ridge becomes centered on the four corners region of the United States. Monday, the Intermountain west will be in a southern flow helping to advect in some moisture for some possible isolated thunderstorms in the afternoon and evening. These storms currently appear to remain attached to the higher terrain so low pops were added to those areas. Tuesday and Wednesday, the flow turns Northwesterly advecting in warm dry air to really mitigate our storm chances in the afternoon and evening. The high pressure system is progged to remain over the four corners region through the week to keep us mostly dry for the remainder of the week. && .AVIATION /00Z TAFS THROUGH 00Z SATURDAY/... Issued at 508 PM MDT Fri Aug 15 2025 Some showers are likely to affect KBFF and KAIA between 02 and 04z. KBFF looks more certain that it will be hit by the storm but KAIA may get missed so a Prob30 was used for this uncertainty. After these showers tonight, the skies should clear for VFR conditions. Widespread showers look to occur after 20z for the KLAR and KCYS and work their way east to affect the Nebraska terminals in the evening. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...None.
