Episode Narrative A ridge of high pressure building up along the Idaho/Montana border placed the Inland Northwest in a moist south-southwesterly flow pattern. Strong insolation across southwest Washington destabilized the lower atmosphere enough to break the capping inversion across this area with rapid thunderstorm development during the late afternoon hours. One thunderstorm over Columbia County in southeast Washington produced a gust front that pushed out across the northeast Blue Mountains and down into the Lewiston area.
Event Narrative A severe thunderstorm in the Blue Mountains over Columbia County in Washington produced a gust front that pushed through the Lewiston area. Lewiston Orchards seemed to feel the brunt of this outflow boundary with wind gusts up to 45 mph recorded at the Lewiston-Nez Perce County Airport. A few small trees were knocked over with trunks estimated at six to eight inches in diameter. Some small branches were broken off as well.
