| Brief Description: A brief tornado developed in the apex of a bow echo that moved across the county. A house was blown off its foundation and moved 35 feet away. A low pressure system with an unusually strong mid and upper level jet streak was moving across the Great Lakes with an associated cold front moving across the upper Ohio valley. Thunderstorms developed across Indiana and moved into West-Central Ohio around mid-afternoon with a distinct bow echo causing wind damage from near to Lima to southeast of Columbus. On the southern edge of the first line of storms, a supercell developed over Central Indiana. This storm evolved into a bow echo and swept across the Dayton metro area causing extensive wind damage and a brief tornado in Greene county. Another supercell developed near Cincinnati and moved southeastward along the Ohio River. This storm produced the F3 tornado in Clermont county. | |||||||||||
