A collection of spectacular tornadoes occurred on the 16th June 2014 that levelled several buildings. The supercells developed in high instability and along a boundary and produced a pair of high contrast tornadoes with two mesocyclones side by side. As seen on the video and explained by the storm chasers, the two tornadoes merge. These are by far the most spectacular tornadoes this season in what was a well below average tornado season in the United States. Here are a couple of videos. http://icons.wxug.com/hurricane/2014/tornadoes-twin-pilger.jpg
