Clean-up is underway in several Ohio communities following a blast of wind and water Wednesday evening that continued through the early morning hours on Thursday.
A series of tornado warnings covered a swath from Marion to Guernsey Counties in the early evening, followed by a long line of storms with a few embedded rotating cells diving southeast from northern Indiana across Ohio during the middle of the night.
National Weather Service survey teams are out in the field assessing damage to determine whether the damage was caused by straight-line thunderstorm winds or an embedded tornado.
From my view, the damage in Caledonia in eastern Marion County was consistent with a small tornado, where the upper story of a building was destroyed, trees sheared, and two-by-fours driven into a home. A funnel cloud was spotted near the ground farther south between Waldo and Prospect, developing beneath a rotating wall cloud.
A barn flattened in northern Union County could have been caused by a downburst (strong downdraft), but the weather service in Wilmington will likely take a look at the damage Friday to be sure. Wind damage in Hilliard along Fishinger Road at Lowe's Home Improvement and at a nearby Speedway gas station was caused by a powerful downdraft.
