Episode Narrative A non-supercell tornado struck a ranch about nine miles east of Manderson.
Event Narrative A tornado struck a ranch, including a home, east of Manderson. Three children were in the house at the time of the tornado. The tornado was about 100 feet wide and traveled approximately one-third mile from north-to-south, crossing State Highway 31 before dissipating. Several trees, two fences, and a wooden corral sustained considerable damage. An All-Terrain Vehicle (ATV) was lifted, spun 180 degrees, and moved about 15 feet. A bicycle was tossed onto the roof of the ranch home and several water bins were tossed about.
This landspout tornado occurred in a post-cold frontal environment. A cold front moved through Manderson around 0830MST on Monday leaving northwest wind of 30 to 40 mph in its wake. Solar heating continued to warm the surface while colder air streamed into the region aloft. This helped set the stage for an unstable atmosphere during the afternoon. A west-moving boundary from showers to the east of Manderson in the Bighorn Mountain foothills helped initiate the updraft that spawned the tornado.
