Numerous photos and videos were taken of a funnel clouds located about 2 miles west-southwest of downtown Lancaster.
A ground survey with assistance form the Fairfield County EMA confirmed a brief and weak tornado touched down in the southwest part of Lancaster.
The survey revealed an eyewitness report of a very weak tornado on the ground near a residence at the west end of Mount Ida Avenue in Lancaster. No damage occurred at this residence. From there the weak tornado moved east through a wheat field with a narrow path of flattened wheat in a convergent pattern. From there the tornado moved between Tarhe Street and Twin Creek Way where minor tree damage occurred, including a couple of uprooted trees and snapped limbs. The tornado appears to have lifted as it approached south Broad Street.
