Event narrative

A trained spotter in Salmon, Idaho reported trees down over roadways, power lines down in three different areas with power outages and a roof over a patio blew off.

Wider weather episode

A 40 to 50 knot mid-level southwest jet maximum combined with unstable conditions over Lemhi County helped initiate a large supercell thunderstorm that brought wind and hail. As the main upper low over Washington and Oregon pushed eastward, thunderstorms developed over Idaho County. One of these storms brought heavy rain that triggered flash flooding over the Sheep Fire Burn area.
