Hail in Benewah County, Idaho

A weather spotter in Fernwood reported hail one inch in diameter. Time was estimated based on radar.

A stationary trough of low pressure along the Pacific Northwest Coastline resulted in moist, unstable, southwesterly flow over the Inland Northwest. A shortwave embedded within the flow, triggered thunderstorms during the evening hours of August 25, 2013. Initially, the threat was focusing on isolated severe storms producing large hail. As the shortwave crossed into the region, a strong squall line crossed from Eastern Washington into northern sections of the Idaho Panhandle resulting in damaging winds and numerous downed trees and power lines.
