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 Pocatello, ID wrote its last area forecast discussion before the first event at Jul 24, 10:27 AM MST, 1 hour 33 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pocatello ID 1127 AM MDT Thu Jul 24 2025 .KEY MESSAGES... - Daily, isolated shower and thunderstorms chances will continue through the weekend (primarily in the mountains), peaking in coverage each afternoon and evening. - Conditions will remain very dry outside of any showers or storms, supporting elevated fire weather conditions due to a combination of low relative humidity and breezy winds. - Temperatures will remain steady through Sunday, ahead of a warming trend starting Monday. && .SHORT TERM /THROUGH FRIDAY NIGHT/... Issued at 155 AM MDT Thu Jul 24 2025 Early morning satellite imagery shows a closed mid/upper-level low off the California Coast as a shortwave trough tracks northeast across the northern Great Basin. This trough will be the main driver of isolated shower and thunderstorm development this afternoon and evening as it passes over eastern Idaho, with a focus further south across the Lower Snake River Plain and eastern Magic Valley south into Utah. Here is where the HREF model probability of thunder shows a 30-50% chance, while elsewhere those chances are closer to that 5-20% range. Have added POPs to the drier biased NBM today to account for these isolated to widely scattered chances further south, in addition to adding a 15% chance up in the east-Central Mountains and Montana Divide region, where ensemble max reflectivity model guidance shows isolated development possible. Stronger storms later today will be capable of producing wind gusts of 35-45 mph and small hail. Outside of these isolated shower and storm chances, conditions will remain dry today with highs in the 80s/90s. Winds will remain breezy out across the Shoshone/Arco/Mud Lake Desert and Upper Snake River Plain region, with gusts peaking this afternoon around 30-40 mph. As that low off the Pacific Coast moves onshore late Thursday into Friday, a secondary shortwave trough will propagate northeast into eastern Idaho for Friday and help kickoff another round of showers/thunderstorms during the afternoon and evening hours. Best chances will shift to being in the Central Mountains, Montana Divide, and South Hills/Albion Mountains west into the Owyhees in that 15-40% range, locally higher up around Lemhi County. Temperatures will hold steady with highs again in the 80s/90s as winds see a slight uptick regionwide, with gusts peaking in the afternoon around 20-40 mph. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... Issued at 155 AM MDT Thu Jul 24 2025 Daily shower and thunderstorm chances will continue through the weekend, primarily in the mountains, as conditions remain predominantly dry and near normal temperatures persist. Courtesy of southwest flow, temperatures will remain steady through the weekend with highs in the low 80s to low 90s, ahead of a warming trend starting Monday as mid/upper-level flow turns southerly. This will push highs back into the upper 80s to upper 90s for the start of the work week. That southerly flow ultimately looks to tap into a plume of monsoonal moisture by midweek out of the Desert Southwest, allowing for moisture to lift north into the northern Rockies. However, the location and placement of that moisture fetch still remains uncertain at this time with a high degree of variability in model guidance. The NBM is currently weighted closer to the ECMWF and favors a drier solution while keeping the bulk of precipitation outside of our area. The GFS in contrast, is favoring better moisture transport into eastern Idaho. We will see exactly how this comes into focus over the coming days so stay tuned. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1127 AM MDT Thu Jul 24 2025 A general area of thunderstorms is expected to develop across southern ID/northern UT this afternoon generally after 20z. There is roughly a 20-30% chance of TS reaching as far north as BYI and PIH this afternoon and early evening. Equal concern will be potential for gusty outflows 30-40kts moving into these terminals even if TS stays outside of the aerodromes. Latest high-res models break down the convection in the 01-03z time frame, but still extend potential outflows in the 25-35kt range as far north as IDA and to a lesser extent DIJ. Have kept this out of the terminals for now, but will be a consideration for 00z issuance as situation develops. Overnight VFR and light winds anticipated at all sites. SUN expected to be the site of concern after 18z Friday with TS expected across central mountains. Latest HREF develops storms north of SUN, so have trended toward development with a slight increase in cloud cover for the afternoon but kept mention of TS out of the terminal for now. && .FIRE WEATHER... Issued at 155 AM MDT Thu Jul 24 2025 A series of shortwave troughs passing over eastern Idaho through the weekend will support daily isolated shower and thunderstorm chances and breezy winds. Given a very dry airmass in place, elevated to near critical fire weather conditions will be possible through the weekend due to a combination of breezy winds and low RHs in the teens/20s. This will especially be the case in FWZ 410 and 413, primarily out across the Arco/Mud Lake Desert where winds will be strongest each day. Temperatures will remain steady through the weekend ahead of a warming trend back starting Monday as southwest flow turns more southerly. That southerly flow ultimately looks to tap into a plume of monsoonal moisture midweek out of the Desert Southwest, allowing for moisture to lift north into the northern Rockies. However, the location and placement of that moisture fetch still remains uncertain at this time with a high degree of variability in model guidance. The NBM is currently weighted closer to the ECMWF and favors a drier solution while keeping the bulk of precipitation outside of our area. The GFS in contrast, is favoring better moisture transport into eastern Idaho. We will see exactly how this comes into focus over the coming days. && .PIH WATCHES/WARNINGS/ADVISORIES...
