The episode as NWS OTX wrote it up.
A strong fast moving cold front brought severe thunderstorms to Extreme Eastern Washington during the afternoon and early evening hours of June 8,2016. The storms produced large hail and damaging wind.The most impressive storm spotter report noted 1.25 inch size hail causing dents in a car at Anatone, Washington. Not much further away in North Idaho the most impressive storm reports included 1.75 inch size hail at Craigmont with numerous 1.00 inch size hail reports near the towns of Winchester and Avery along with several 50 foot cottonwood trees blown over not far from Santa, Idaho.

NWS Spokane, WA wrote its last area forecast discussion before the first event at Jun 8, 1:32 PM PST, 8 minutes earlier.
Area Forecast Discussion National Weather Service Spokane WA 232 PM PDT WED JUN 8 2016 .SYNOPSIS... Strong to severe thunderstorms are likely through evening across southeast Washington and the southern Idaho panhandle. Gusty winds will be from the Cascade valleys into the Columbia Basin. This is all due to a cold front that will move through the region this evening. Cooler, breezy and showery weather will develop over the Inland Northwest for Friday and through the weekend. A slow warming trend is anticipated for early next week. && .DISCUSSION... The remainder of the afternoon and evening hours...the focus will be on strong to severe storms across southeastern WA and the Idaho Panhandle. The cold front is traversing the CWA a bit slower than expected and has allowed sufficient heating south of a line from Clark Fork to La Crosse. This could mean two things, the threat for strong storms will arc further to the north and west than previously expected and the threat for strong storms may linger longer into the evening. As such, per coordination with surrounding offices and the storm prediction center, a severe thunderstorm watch will be issued for the aforementioned areas through this evening for storms capable of damaging winds and large hail. These storms will also be capable of heavy rainfall but the storm motion is so fast that it will take training storms in the event to get flash flooding so will hold off on any flood highlights at this time. For the remainder of Central and NE Washington and far N Idaho Panhandle, the threat for strong storms is much lower. There will be a few embedded storms at times but the main issues will be scattered showers along a slow moving frontal band and gusty winds capable of fanning any new fire starts from earlier lightning /sb Thursday through Sunday: A cooler and showery weather pattern will be over the Inland NW for the later half of the week and the upcoming weekend. In the wake of strong cold front this evening, an upper level low pressure system will roll into the Pacific NW and settle in for the weekend. The strong to severe convection from this evening will wane overnight over the Idaho Panhandle. Gusty winds will persist from the lee side Cascade valleys into the Columbia Basin overnight and taper off by Thursday morning. Gusty winds will develop again Thursday afternoon with speeds to 20 mph. The models show a secondary front with an embedded shortwave will round the trough and reach the Cascades by 00z Friday. Surface based convection will develop over the Cascades Thursday afternoon and ahead of the feature over the Blue mountains, but it will not be at the caliber of those seen today. Instability and sheer will be less and as the colder trough moves in, anticipate more showery conditions with isolated embedded thunderstorms. This band of showers will accompany the shortwave and move across eastern Washington Thursday afternoon, and then stalling over extreme eastern Washington into north Idaho by Thursday evening and Friday. Did raise pops for Thursday night into Friday to support the better chances of precipitation. The cloud cover and precipitation will keep temperatures on the cool side on Friday and did push temperatures down slightly for Friday. By Saturday, the upper trough will swing through Washington, but models are differing on the track of its center. The ECMWF indicates a northward track of the low across BC, while the GFS and GEM show this feature lingering over Washington into north Idaho for the weekend. Did opt for a compromise of the model solutions, kept shower coverage diurnally driven over the higher terrain. Could still see a hint of thunderstorms especially over north Idaho. Across the lowlands of the Columbia Basin, shower chance will be minimal. Cool and below normal temperatures will prevail through the weekend. /rfox Monday through Wednesday: Swift SW stearing flow will produce a number of short-wave troughs that will introduce isolated to scattered showers and thunderstorms each day.bz && .AVIATION... 18Z TAFS: A cold currently stalled across Central/NE WA will continue to focus elevated showers and t-storms through 20z. The front will begin to make a move east around 21Z and interact with deep instability along an axis from NE Oregon and NW Montana. Clusters of t-storms are expected to develop across Ern WA and N ID impacting Spokane-Cd'A but the threat for scattered strong to severe storms will focus along and south of Walla Walla to Pullman to Mullan including the Pullman and Lewiston terminals. Chances increase further even further south. These storms will be capable of damaging winds and large hail btwn 21-02Z. Gusty west winds will develop behind the front with the potential for sustained speeds 15-25 and gusts near 30 mph. Some guidance is indicating strong speeds for Wenatchee arnd 00z so this will be monitored for future updates. /sb && .PRELIMINARY POINT TEMPS/POPS...
