According to family still in Ohio, the predominant damage was
north of a line running along US 35 from the northern suburbs
of Dayton, north of Xenia and ending in southeast Pickaway County
(SE of Circleville). The northern edge of the impact area
picked up Celina (40 mi NNW of Dayton) and extended SE to SE
Pickaway County (but staying south of Circleville).
Like all tornado events in that part of the country, the major
damage was spotty as the funnel clouds skipped along ... and
more focused on the western end of the storm track in this case.
