This is on I-70 just west of the airport Friday evening. Note: rough language.
To help you understand what you are seeing:
These are power flashes which are caused when a tornado intersects power lines and causes transformers to blow. The car comes upon power lines across I-70 seconds later. The tornado is crossing the highway.
One of the drivers says "car" when this object (above right in relation to the car in front) flies. I've looked at the video several times and it might be a car. Whatever it is, it is pretty good size.
