The episode as NWS PIH wrote it up.
Butte County received two wind reports in excess of 58 mph northwest of Atomic City.
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 May 14, 1:13 PM MST, 2 hours 47 minutes earlier.
Area Forecast Discussion National Weather Service Pocatello ID 213 PM MDT Tue May 14 2019 .SHORT TERM...Tonight through Fri night. Instability ahead of an incoming spring storm continues the thunderstorm threat for this afternoon and evening. CAPE and strongly negative Lifted Indices are strongest south and east of the Snake River, and this is where thunderstorms are currently developing. The low creating all this will continue a slow march to the west coast, and dig southward some more. This will allow a great tap into subtropical moisture that should last beyond Wed and at least through Fri. National WPC has put parts of Lemhi/Custer/Blaine county in a marginal category for excessive rainfall on Thu/Thu night--pretty low possibility right now. Much will depend on where this subtropical plume of moisture tracks; it will likely be a very thin strip, although it has potential to track from west to east and actually affect a broader area. All the southerly air flow means temperatures will not cool off much for the afternoon compared to now, still staying well above normal. Overnight lows with the cloud cover will be mild during this near-term period. Outside of thunderstorms, do not see more than breezy conditions, and mostly in the eastern Magic Valley and Snake River plain. On Fri, the low center of this storm tracks over southern Idaho. Its cold core will bring temperatures down and there is the potential for snow levels once again developing at elevations above 7800 feet. All this precipitation means that area rivers and streams will be pushed to their limits, and possibly beyond and into flood conditions. Currently, the one place in the next 72 hours to respond to that level is the Wood River at Hailey-more down below in Hydrology. Messick .LONG TERM...Saturday through next Tuesday. Transient ridging will pass through Idaho throughout the day Saturday, but active weather will continue Saturday night and into next week. A deep upper trough will eject a series of shortwaves, and will carry plenty of moisture through southeast Idaho. Widespread showers and isolated to scattered afternoon thunderstorms are likely Sunday, given the negative tilt of the approaching upper trough. Models offer fairly similar solutions through the weekend, though the ECMWF begins to evolve into a split flow Monday morning. It cuts off a low over the Las Vegas area, while the GFS maintains an open trough, though it does develop a cutoff low off the California coast Tuesday morning. Main concerns in the long-term will be the duration and intensity of rainfall which will impact river flows, and the intensity of the thunderstorms that develop over the afternoon and evening hours. Hinsberger && .AVIATION...Plenty of instability this afternoon and evening with a deepening upper trough looms in the eastern Pacific. There is a weak shortwave that will influence convection today. High-res models depict isolated cells beginning around 20Z this afternoon with effective shear around 20 to 30 kts. Main concern will be strong outflow winds with forecast soundings resembling an inverted-V. Hinsberger && .HYDROLOGY...Precipitation amounts for today through Wed are down, and the flooding at Hailey on the Wood River is delayed, as the precipitation is not accelerating the snow melt. However, it is still expected. Henrys Fork and the Lost River are also quickly rising to near alert stage, when an Advisory would be appropriate. Add to this being in the vicinity of a margainal excessive rainfall area by WPC for Thu/Thu night means that the flooding situation should worsen. && .PIH WATCHES/WARNINGS/ADVISORIES... None. &&
