NWS Pocatello, ID wrote its last area forecast discussion before the first event at Jul 29, 1:20 AM MST, 27 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pocatello ID 220 AM MDT Tue Jul 29 2025 .KEY MESSAGES... - Daily, isolated to scattered showers and thunderstorms will continue through the weekend, primarily each afternoon and evening. Stronger storms will be capable of producing gusty winds, small hail, and heavy rain. - 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 near/above normal through Wednesday, ahead of a gradual cooling trend back starting Thursday. && .SHORT TERM /THROUGH WEDNESDAY NIGHT/... Issued at 220 AM MDT Tue Jul 29 2025 Early morning satellite imagery shows a series of shortwave troughs continuing to lift northeast out of California and Nevada into the PacNW and northern Rockies. Following isolated showers and thunderstorms early this morning in the Central Mountains, yet another round of isolated to scattered showers and thunderstorms are expected to develop this afternoon and evening. The primary focus will remain in the Central Mountains east along the Montana Divide, with the exception being today now including at least isolated activity expanding near regionwide. As a result, look for an uptick in thunderstorm coverage compared to what we have seen the past several days, with the HREF model probability of thunder showing a 30-70% chance further north (locally higher up to a 70-90% chance across northern Lemhi County), along with a 10-30% chance elsewhere. Stronger storms will be capable of producing wind gusts up to 50 mph, small hail, and heavy rain. Outside of any showers or storms, conditions will remain hot and dry with afternoon RHs in the single digits/teens for most. Highs today will be similar to what we saw out there yesterday in the mid 80s to mid 90s, with afternoon synoptic wind gusts peaking around 15-30 mph. Dry conditions will progressively return overnight tonight and continue through Wednesday morning, ahead of another round of showers and thunderstorms during the afternoon and evening hours as another shortwave trough passes overhead. Best scattered coverage will remain in the Central Mountains and MT/WY border region, with isolated coverage elsewhere. Stronger storms will again remain capable of producing wind gusts up to 50 mph, small hail, and heavy rain. Highs Wednesday will again be in the mid 80s to mid 90s, with afternoon synoptic wind gusts peaking around 15-30 mph. && .LONG TERM /THURSDAY THROUGH NEXT TUESDAY/... Issued at 220 AM MDT Tue Jul 29 2025 Daily, isolated to scattered showers and thunderstorms will continue through the weekend across eastern Idaho, as a series of shortwave troughs continue to support sufficient instability and moisture transport each day. As a result, we will see shower and thunderstorm coverage peak diurnally each afternoon and evening with daytime heating. Best thunderstorm coverage is expected in the mountains, with more isolated coverage across the Snake River Plain. Outside of any gusty thunderstorm outflow winds, winds look to remain light through the extended forecast timeframe. Following temperatures peaking Tuesday and Wednesday with highs in the mid 80s to mid 90s, we will see a gradual cooling trend return to finish out the week, with highs dropping to the 70s/80s courtesy of increasingly zonal flow. Ensemble model guidance diverges early next week with split solutions showing a mid/upper-level low tracking through the PacNW and northern Rockies, while other guidance shows zonal/SW flow which would keep conditions drier. The NBM is leaning more towards the drier solution at this time, favoring drier and quieter conditions starting early next week, but at least keeping isolated shower and thunderstorm coverage around primarily in the mountains along with continued cooling temperatures. The GFS continues to be much drier solution in comparison to the wetter ECMWF, so we will continue to monitor these trends as they come into focus over the coming days. Nonetheless, our active daily shower and thunderstorm pattern looks to continue through the extended forecast timeframe into next week. && .AVIATION /06Z TAFS THROUGH 06Z WEDNESDAY/... Issued at 1055 PM MDT Mon Jul 28 2025 Mainly high-level cirriform clouds are expected during the next 24 hours, with occasional mid-level cloudiness at KSUN and KDIJ. The risk of TSRA has lowered below mentionable threshold at KBYI. This leaves only KSUN and KDIJ at risk for TSRA on Tue afternoon/evening. VSBY should not be restricted with upwind wildfires staying small. Wind will be light outside of TSRA, with some areas getting slope-valley effect wind at least briefly. && .FIRE WEATHER... Issued at 220 AM MDT Tue Jul 29 2025 Daily, isolated to scattered showers and thunderstorms will continue each day through the weekend as a series of shortwave troughs support sufficient instability and moisture transport into eastern Idaho. As a result, we will see shower and thunderstorm coverage peak each afternoon and evening with daytime heating, with very isolated chances possible overnight and during the morning hours. Best scattered coverage will remain confined to Idaho Fire Weather Zones 411, 422, 475, and 476, with more isolated coverage in Zones 410, 413, 425, and 427. Red Flag Warning criteria will need to be evaluated each day given scattered coverage of thunderstorms in zones that are approaching critical (411/475/476) or are already critical (422). Highs in the mid 80s to mid 90s early this week will see a gradual cooling trend starting Thursday, as highs return to the 70s and 80s later in the week. Minimum RHs will remain very dry through midweek in the single digits and teens (20s and 30s further north), ahead of a gradual improvement regionwide later in the week given more zonal flow overhead, with RHs returning mostly to the teens/20s with pockets in the 30s. Winds outside of any gusty thunderstorm outflow winds will remain light this week, with gusts peaking generally around 15-30 mph. While a few locations will approach critical thresholds with afternoon humidities in the single digits/teens and wind gusts up to 15-30 mph, widespread critical conditions are not expected in this category. However, elevated to near critical fire weather conditions will remain possible due to scattered thunderstorm coverage, especially in the mountains further north. && .PIH WATCHES/WARNINGS/ADVISORIES...
