Yesterday afternoon, the NWS in Wilmington confirmed that an EF-0 tornado did indeed touchdown Friday night. It was not, however, within any of the tornado warnings that were issued.
The tornado occurred in Stonelick Township in northeastern Clermont County, 3 miles south-southwest of Newtonsville, or near Goshen approximately 12:40 Saturday morning. The damage consisted of 3 homes and a garage with minor to major roof damage, tree damage, and a home where the porch was lifted off.
Based on the damage, the NWS determined that this was a mid-range EF-0 with winds of 70-75 mph.
No warnings were in effect at 12:40 AM Saturday for the area where the tornado occurred. However, a Severe Thunderstorm Warning was issued at 12:43 AM for radar-indicated storms that were capable of winds to 60 MPH in northeast Clermont County (this storm, which produced the tornado), and a tornado warning was issued later (around 1AM) for southern Clermont County, for a rotating storm in northern Pendleton County. We cannot fault the NWS, as they were in the process of issuing the thunderstorm warning (which was based on radar information that was only 3 minutes old at the time of the tornado) on a busy night, and radar may not have seen the tornado.
