Episode Narrative An upper low drifted slowly southeast across western Wyoming during the afternoon hours. Cold air aloft coupled with daytime heating helped to generate a few severe thunderstorms in Fremont and Hot Springs counties.
Event Narrative Thunderstorm wind gusts measured as high as 74 mph caused damage to more than a dozen mature trees at the Riverton Country Club. A 40-foot spruce tree was toppled and several limbs up to nine inches in diameter were brought down during the storm. Rainfall of one-half inch to upwards of one inch came down in sheets. The storm generally followed Riverview Road on the south side of U.S. Highway 26. One rancher claimed it was the hardest he had seen it rain in his 35 years at his location near Kinnear.
