National Weather Service meteorologists surveyed the damage in northern Lamar County into extreme southern Marion County and determined it was the result of an EF-1 tornado.

A tornado touched down just southwest of the Beaverton community in Lamar county Wednesday evening. The tornado first touched down along Highway 278 with very minor tree damage noted. The tornado then moved almost due east across Highway 278 producing sporadic tree damage as it crossed Turkey Branch Road and Markham Road in far eastern Lamar County. A small barn was also damaged in this area. The tornado then straddled the Fayette and Marion county line with mostly softwood trees uprooted in this forested area. The tornado crossed County Road 69 moving completely into southern Marion county and into the western portions of Winfield. The most notable damage was in downtown Winfield as the tornado strengthened to EF-1 intensity. Here damage to several buildings in downtown was noted along Highway 43. Several businesses sustained roof and structural damage with windows being blown out of others. A strip mall lost a large section of its roof structure. The damage here was deemed 110 mph. The tornado was also at its widest going through downtown at approximately 300 yards wide. The tornado narrowed fairly rapidly as it exited downtown and began to wind down in the more residential areas east of town. Some homes sustained minor roof damage along Highway 43 near the Highway 129 intersection. Further east the tornado lifted with only sporadic minor tree damage noted.

A brief EF0 tornado formed near Glencoe Middle School where some roof damage was observed. The tornado moved northeast across Lonesome Bend Road snapping a couple trees and causing shingle damage along Stone Street. It downed more trees, peeled back the roof a barn, and moved a travel trailer just west of Pineview Avenue. After crossing Pineview Avenue, it destroyed a small shed and caused roof damage to a home on Barron Way before dissipating.
