This was taken off an interstate 79 exit near Waynesburg, PA on September 2, 2013. It is a storm that looked to have some tornado-like characteristics with the look of the clouds. I thought a funnel could come out of them at any second. Though no funnel was ever reported that I know of, it was still a pretty nasty thunderstorm. It made for some beautiful skies and a lot of lightning. I was lucky enough to catch a lightning strike in one of the shots.
