| Brief Description: A brick, ranch style home in Fairplain Township was totally destroyed by an apparent tornado. No one actually saw a tornado, but the debris pattern and localization of the damage strongly suggested a tornado rather than straight-line thunderstorm winds. Seven people were in the home at the time, but no one was injured. A small shed was also torn up. The path length and width were estimated from the debris pattern. Trees up to 10 inches in diameter were broken off at the ground in a counter-clockwise pattern. | |||||||||||
