This image is a video snapshot taken at 8:20 pm. The white house in the picture is facing south and the path of this rotating cloud is moving in a southeast direction. I would assume that staying on this course it would of passed directly over the Jewel-Osco on 159th & Farrell road. The video is sped up and the contrast has been increased to make it easier to see the rotation. At the time of this event due to the blowing rain, wind and the way the sun was lighting the clouds this rotation was hard to see. It was only after viewing the video that I realized how close our house was in the path of a potential tornado. It was about this time that the actual F1 tornado was passing over Farrell & Oak avenue
