Event narrative (NOAA)
A storm survey concluded that an EF-3 tornado crossed into McDonald County from adjacent Delaware County, Oklahoma. The tornado crossed Stateline Road 2.8 miles north of Southwest City, Missouri at 7:26 pm and destroyed a single family resident and vehicles near the residence. The vehicles rolled up to 200 yards away from the house. Several trees were uprooted along the path of the tornado as it tracked southeast towards chicken houses near the intersection of Highway 43 and Farm Road 4385. The tornado lifted right before reaching Highway 43 about 2.2 miles north northeast of Southwest City. Maximum wind speeds were estimated between 150 and 160 mph. The maximum width of the path was estimated at a quarter of a mile wide.
