Episode Narrative A warm front attempted to move in during the day, but a strong easterly flow and extensive low clouds and fog did not allow the boundary to mix northward. Low pressure moved from Missouri towards northern Indiana during the evening hours. A line of strong to severe storms initiated ahead of the low and along the warm front and moved into southern parts of the area. A strong low level jet allowed for temperatures and moisture above the surface to increase, causing elevated instability. Damage occurred across several counties in southern portions with much of it occurring at tree top and roof levels, suggesting winds could not fully mix down. Surveys of several areas indicated that brief circulations were embedded within these wind damage swaths, leading to the confirmation of several weak tornadoes.
Event Narrative A survey of straight line wind damage indicated a circulation touched down north of the intersection of County Road 400 N and US 27, near Antiville. Evidence in trees suggested the circulation touched down in an open field and tracked northeast across US 27, snapping 5 power poles as it crossed, causing power flashes observed by local residents. The circulation did not remain in contact with the ground during its roughly 7 mile track. Areas of snapped trees or tree limbs were seen along the track. Structural damage was noted in two locations, mainly to garages or pole barns.
