Hail — Lemhi, Idaho

2013-08-01 · near Carmen, Lemhi, Idaho

Event narrative

A trained spotter northeast of Carmen estimated that most hail sizes ranged between 0.75 and 1 but there were a few that were up to ping pong size. The hail damaged several fruit trees and tomatoes. His neighbor's wood siding on his house was also damaged.

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.
