The episode as NWS OTX wrote it up.
A wet spring contributed to saturated soils around the region. Scattered debris flows and landslides occurred over much of the region form March through May. Isolated landslides and debris flows continued to be reported into the month of June. In Spokane Valley a debris flow destroyed an out building and flooded a basement of a home.

Area Forecast Discussion National Weather Service Spokane WA 234 PM PDT Thu Jun 1 2017 .SYNOPSIS... A return to more seasonal temperatures into the weekend will allow the rivers in north central Washington to slowly recede. Scattered showers will taper off this evening. High pressure should bring drier weather for Friday and Saturday. Cooler and occasionally showery weather is forecast as early as Saturday night and on through Sunday and into Monday. More dry and warm weather possible by middle of next week. && .DISCUSSION... Today and tonight: The upper trough continues to bring us showers and thunderstorms this afternoon and these will continue into the early evening, tapering off from west to east. The frontal band has moved east the next shortwave is moving through the area from the southwest. This is bringing with it a few vorticity maxima and providing lift, along with some uplope flow, to initate the showers this afternoon. Central and eastern Washington saw a good deal of sun this afternoon which, together with the upper level cooling of the trough have increased our instability over the basin allowing for a few lightning strikes. The best threat for thunderstorms the rest of the afternoon is over the northeast mountain zones, where CAPE values max out >600 J/kg. Convection will decrease from west to east as through the evening. As the shortwave moves out we'll see a clearing trend through the night. Moisture willlinger in the boundary layer overnight, however, so some patchy fog is possible Friday morning, mainly northern and Cascade valleys. /bw Friday and Saturday: The shortwave from today will have exited into Montana by tomorrow with shortwave ridging building in behind it. Boundary layer moisture will remain high enough over the northeast valleys to allow for some fog potential Friday morning but overall a clearing and drying trend will ensue into Saturday. By Saturday evening, PWATs begin to rise back to near 1 inch as the flow turns to the southwest ahead of a deep trough off the coast. There is enough instability and some upslope flow over the central ID Panhandle Saturday evening to warrant a slight chance mention at an isolated shower or thunderstorm with a better chance overnight. Mid to high level clouds will also be on the increase Saturday. Saturday night through Monday night: A vort max will ride up from the southwest Saturday night which will allow for some shower chances over the eastern third of WA and the ID Panhandle for Saturday night into early Sunday morning. The incoming shortwave and associated cold front will reinforce the shower and thunderstorm chances for Sunday afternoon and evening, again, mainly over the eastern half of our forecast area. The best instability looks to set up over the ID Panhandle and even more-so in to MT supporting the inherited thunderstorm chances. Given the alignment of CAPE values and 0-6 km deep layer shear, the potential is there for some small hail and gusty winds with these storms over our eastern counties, with locally heavy rain more likely. Models are hinting at the possibility of some decent rainfall amounts over the central ID Panhandle but will need to continue to be refined as we get closer. This system exits overnight Sunday with some ridging and therefore a drying trend building in again for Monday. Temperatures still look to be within a few degrees either side of normal for this time of year, generally in the upper 60s and 70s. The exception to this still looks to be on Saturday which will feature high temperatures in the 80s for many locations. /Kalin Tuesday through Thursday...Amplifying ridging allows for a warming and drying trend Tuesday through Wednesday night. The ridge axis gets pushed into Western Montana Wednesday night so there is a bit more warm air advection on the west side of the ridge axis but the flow remains void of disturbances that could kick off convection so the forecast remains dry. There is some model agreement in allowing a very slow moving negatively tilted frontal zone into Central and Eastern Washington that would affect portions of the North Idaho Panhandle Thursday night. This setup would allow the warming trend to peak Wednesday with the most significant cooling occurring over the Washington Cascades Thursday coupled with pops for showers and possibly thunderstorms while further east over North Idaho Thursday may end up nearly as warm as Wednesday due to the slow arrival of the front there. /Pelatti && .AVIATION... 18Z TAFS: The frontal band leaving lingering light showers over southeast Washington and much of north Idaho is slowly moving out. Sites including KPUW & KLWS, and part of the KGEG-KCOE corridor will get a brief break in the rain chances early this afternoon before the next shortwave moves in from the southwest and increases cloud cover and convection across the region. All locations will see showers with cigs as low 4k ft. There is potential for a few thunderstorms but expected to remain over the NE mountains and won't affect any TAF sites. Clouds and showers are expected to dissipate after 04z with partial clearing. Some stratus and fog is possible mainly in the northern sheltered valleys late tonight /bw && .PRELIMINARY POINT TEMPS/POPS...
