There was one tornado on September 29, 1966:  An estimated F3 that moved through parts of the Cleveland, OH area.  22 people had minor injuries. Approximately 248 structures were damaged or destroyed.  The tornado moved eastward near Warrensville Heights and North Randall.  Per Thomas Grazulis in Significant Tornadoes, one home was “nearly leveled”.  He also notes that the tornado was described as “a big pillar”.  Per the Storm Data entry, “this was the latest date of occurrence of a tornado in Cuyahoga County since the beginning of weather records in 1870.”  This record held until November 10, 2002 when an F2 in Summit County, OH weakened to an F1 as it crossed into Cuyahoga County south of Glenwillow. Here is the NCDC entry for that event
