The episode as NWS PIH wrote it up.
A large number of thunderstorms occurred in southeastern Idaho on the afternoon and evening of June 6th.
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 6, 1:28 PM MST, 2 hours 17 minutes earlier.
Area Forecast Discussion National Weather Service Pocatello ID 228 PM MDT Thu Jun 6 2019 .SHORT TERM...Tonight through Sun. SPC has put much of the forecast area under a Severe Thunderstorm Watch (number 337) until 11 pm tonight. Very warm and unstable air will clash with some of the coldest air the region has ever seen during the month of June. This is not only powering the thunderstorms, but there should be plenty of wind associated with the cold front. This will last through Friday, although there should be a brief lull in the coldest part of the morning, from sunrise to mid-morning. Then very windy conditions should return. Local study keeps the criteria in the Wind Advisory range. There is also a risk of blowing dust after a couple of dry days in the Snake River plain. Showers and thunderstorms will continue on Fri, although not to the magnitude of tonight. On Saturday, as the cold front continues its eastward track, showers will be more limited to the eastern and northern highlands. The cold air will have settled in, with high temperatures only reaching the 50s for places in the eastern Magic Valley and Snake River plain. This of course means accumulating snow in the higher elevations, but the precipitation is not heavy for the locations expected to snow, so a storm total up to 3 inches is about the limit for Fri night to Sat morning. Conditions start to clear Sat night after midnight, and record to near-record cold for this time of year is likely. Frost is nearly likely for Sun morning. Messick .LONG TERM...Sunday night through next Thursday. Ridging aloft will prevail over the region through about mid-week, bringing mostly clear skies and warmer temperatures. Starting Wednesday, a cutoff low will begin to fill and lift through California ahead of a shortwave trough around 140W. GFS is indicating showers Wednesday night across southeast Idaho, while the ECMWF is dry. Both models ramp up convection Thursday afternoon as the trough swings through the region. Hinsberger && .AVIATION...Main concern will be for severe thunderstorms late this afternoon and evening while a cold front pushes through around 03Z to 06Z. VFR conditions should prevail, but a passing shower could briefly drop visibility below VFR. In the post-frontal airmass, there will be a greater potential for MVFR ceilings beginning around sunrise tomorrow, particularly at KSUN and KDIJ and maybe KIDA. MOS guidance is bringing the strongest winds late tonight as pressure gradient remains tight over the region behind the cold front. Hinsberger && .HYDROLOGY...Wood River in Hailey and the Lost River at Howell Ranch (near Chilly Barton Flat) continue to be in or near minor flood stage, and so the Warning and Advisory continue. All points along the Wood, Little Wood, and both Big and Little Lost Rivers will continue with rising stages due to snow melt until Fri night. At that point, much colder air, bordering record cold for the month of June, will severely slow melting and give the rivers a chance at partial recovery to below even action stage. Snow melt is not done, however, and expect the sunny skies next week to bring back higher stages. Messick && .PIH WATCHES/WARNINGS/ADVISORIES... Wind Advisory from 9 PM this evening to 10 PM MDT Friday for IDZ052-053. Wind Advisory from 11 AM to 10 PM MDT Friday for IDZ056>058- 062>065. Wind Advisory from 3 AM to 10 PM MDT Friday for IDZ051-054-055. &&
