A powerful cold front pushed through the lower Ohio Valley during the evening hours on July 7. Ahead of this front, unseasonably warm and humid conditions prevailed with high temperatures in the lower 90s and dewpoints in the low to mid 70s. This provided plenty of instability. Several lines of thunderstorms developed across central Indiana and then moved south into central Kentucky. Some large hail up to golf ball size in diameter was reported but the main impact was damaging wind gusts which brought down many trees and power lines with caused some structural damage as well. The storms were also noted for being prolific in-cloud and cloud-to-ground lightning producers.
