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 17, 1:00 PM MST, 3 hours 30 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Pocatello ID Issued by National Weather Service Salt Lake City UT 200 PM MDT Thu Jul 17 2025 .KEY MESSAGES... - Isolated showers and thunderstorms along the Utah border this afternoon and evening with gusty outflow winds. - Near critical fire conditions today for winds and humidity, then critical conditions Friday for thunderstorms and gusty outflows. - Warming trend continues into the weekend. && .SHORT TERM /THROUGH FRIDAY/... Issued at 200 PM MDT Thu Jul 17 2025 Moisture along the UT border may be enough for isolated thunderstorms this afternoon and early evening. Gusty outflow winds 40-45 mph will be possible, but little precipitation is expected with the very dry air mass in place. HREF shows a 50% chance of exceeding 40 kts across southern Cassia county this evening. Breezy winds continue to develop across portions of the Snake Plain today as airmass reaches full mixing potential. Shortwave advancing into the PacNW should allow for additional moisture to advance into East Idaho during the day on Friday. Additional thunderstorm development is expected once again. Steep lapse rates will allow isolated gust potential over 50 mph. HREF paints a greater than 50% chance of exceeding 40 kts across a much wider swath of the region, with pockets of a greater than 70% chance. Long term discussion: && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Issued at 200 PM MDT Thu Jul 17 2025 Remnants of shortwave slide north along the Canadian border on Saturday. A few thunderstorms may still be possible, again with locally gusty outflows over 40 mph. Outside of the storms, gusty winds remain possible especially over the Snake Plain, and may lead to another day of critical or near critical fire conditions. Similar conditions exist for Sunday. Models amplify the trough along the PacNW coast into next week, leading to a strengthening of southerly flow across East Idaho. Moisture does not look to edge into the region, but is still spotty and uncertain enough to only lead to isolated thunderstorm chances at best, for now. Temperatures remain stable in the upper 80s/lower 90s for most of East Idaho into next week. Expect breezy conditions within the continued dry air mass for occasional critical or near critical fire conditions. && .AVIATION /00Z TAFS THROUGH 00Z SATURDAY/... Issued at 200 PM MDT Thu Jul 17 2025 VFR weather is expected through the next 24 hours. Gusty winds are possible up to 25kts at all TAF sites through this evening except SUN, although we could see sporadic gusts from the southwest at SUN before the usual switch to northwest this evening. For Friday afternoon, thunderstorms are expected...although the potential at any TAF site is too low to mention right now due to lack of confidence in timing and location. Gusts over 35 kts are likely with gusts over 45kts possible with some storms tomorrow. && .FIRE WEATHER... Issued at 200 PM MDT Thu Jul 17 2025 We are looking for near-critical to critical fire weather conditions for the next 24-36 hours across central and eastern Idaho. Through this evening, we are expecting some pockets of critical conditions due to low humidity and gusty winds, especially across the Snake Plain (410) and 425 (Magic Valley). Although fuels are not critical right now, gusts of 25-35 mph are likely with low humidity in the central mountains (475/476). Isolated thunderstorms with gusts over 40 mph are possible this evening along the Utah border, especially across Zone 427. We may see some virga or isolated storms with gusty winds overnight elsewhere, mainly though along the Utah border. For tomorrow, thunderstorm potential along with coverage is higher. The highest chance for storms will be in 2 main areas. The first in higher elevations south of the Snake Plain (413 and 427). The other is across the central mountains from around Mackay to Monida Pass (411 and 476). Elsewhere, look for more isolated coverage. There is a 70-90% chance of gusts exceeding 40 mph in those areas already mentioned with some gusts over 50 mph likely. Storms tomorrow will likely be a mix of wet and dry as well. We will be issuing a RED FLAG WARNING for Zones 413 and 427 since fuels are critical. We will NOT issue one for Zones 411 and 476 after talking with local fire folks and determining fuels are not critical enough at the moment. The timeframe will be 1pm to Midnight. Saturday COULD be another critical fire weather day, depending on how things trend. Isolated thunderstorms are possible again across Zones 411, 413 and 427. We are also looking for increasing winds OUTSIDE of thunderstorms and lower humidity. If we do reach thresholds, it will be across the Snake Plain (410) and Magic Valley (425). Winds will be gusty across the central mountains, but again fuels are NOT critical in those zones. Heading into early next week, we are looking at an ongoing potential for isolated showers and storms closer to the Montana border. Winds outside of storms remain breezy, but overall humidity forecasts are trending higher. && .PIH WATCHES/WARNINGS/ADVISORIES... Red Flag Warning from 1 PM Friday to midnight MDT Friday night for IDZ413-427. && SHORT TERM...DMH LONG TERM...DMH AVIATION...13 FIRE WEATHER...13
