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 Jun 27, 1:41 AM MST, 11 hours 19 minutes earlier.
Area Forecast Discussion National Weather Service Pocatello ID 241 AM MDT Tue Jun 27 2017 .SHORT TERM...Today and Tonight. Waves of showers and thunderstorms continue early this morning. Gusts over 35mph and some downpours have been common. The trend through noon appears to push one area through the eastern highlands, and a second one across the central mountains. Locally heavy downpours and gusty winds will be the main risks. By this afternoon, the focus for strong/possibly severe storms will be across the Upper Snake Highlands and Plain. How far southwest is still a bit in question. Some of the high resolution data suggests it won't make it too far past a Palisades to INL line, BUT there are a few indications it could make it almost to Craters and Pocatello. This appears to be a situation we will have to monitor once things get going this afternoon. Most storms in the areas mentioned above will see strong winds and small hail, but just like yesterday a few severe storms are possible especially across the Upper Snake Highlands. The risk would be hail over 1" and winds over 60mph in that scenario. This is would also be the area to look for heavy rainfall as we do have enough moisture for storms to be both "dry" and wet (over 0.10"). Elsewhere, showers and storms will continue across the central mountains but the risk of hail and wind will be less. Outside of where we see storms today, expect it be breezy with sustained winds of 20-30 mph with higher gusts. At this point though, we are seeing enough impacts for any headlines BUT don't be surprised if some pockets of blowing dust appear. For tonight, activity will be diminishing with lingering showers mainly across the north. It will be noticeably cooler, around 7-15 degrees. Keyes .LONG TERM...Wednesday Through Next Tuesday. As the next storm drops southeast out of Canada tomorrow and tomorrow night, we will see more showers and storms especially during the afternoon. It will be a bit cooler than today and breezy. Again, no wind headlines anticipated BUT pockets of blowing dust could re-appear. Dry weather will round out the end of the last week of June 2017. A slow warm up is forecast this point in time. The next storm to affect us arrives Saturday for more showers and thunderstorms across the central mountains and Upper Snake Highlands. early next week will be back to dry and warm as southwest flow develops and pushes some of us back toward the 90s. Keyes && .AVIATION...Showers and isold tstms remain possible this morning at KSUN...KBYI...and KPIH. Showers/tstms will continue around KIDA and KDIJ thru tonight. Gusty outflow winds are possible. Overall winds will increase from the SW by this aftn in the Snake River Plain and eastern Magic Valley. Cig/vis expected to remain VFR. Hedges && .FIRE WEATHER...Scattered showers and isolated thunderstorms this morning will become more numerous by this afternoon across the upper Snake River Plain and Upper Snake Highlands. Gusty outflow winds will remain possible through this evening. A cold front moving through Idaho today will bring cooler temperatures and slightly higher humidity...but also strong southwest winds by this afternoon. Thunderstorms are again a threat on Wednesday...but mainly over the eastern and southern highlands and near the Divide. The rest of the week into the weekend looks dry and warmer. Hedges && .PIH WATCHES/WARNINGS/ADVISORIES... None. &&
