At 2.6 Miles wide, this is the largest Tornado ever recorded. Touchdown was near El Reno Oklahoma on 5-31-13. This tornado was very deceptive to many due to its appearance and size.
The bulk of what you are seeing at 2:50 is a large wedge tornado. When the base lifts and flattens at around 3:05 it gave the “tornado” a mesocyclone appearance and when it started dropping large sub-vorticies many chasers lost sight of the big picture.
At around 6:02, the tornado is taking up almost the entire frame, however the huge sub-vorticies to the lower right appear to be the only point of ground rotation.
What many thought were several tornadoes was in fact just 1. At time code 6:30, this is a separate, smaller anticyclonic tornado.
