Red Barn Supercell
It was a very hot summer day in Illinois with oppressive humidity and extremely unstable air. At 5PM this storm exploded into existence near Utica and in less than an hour it was dropping 4" hail. After leaving the storm to cross the Illinois River and avoid getting caught in the hail, I met back up with it here. The supercell was showing some of the best structure I've seen with an obvious spiral shape. The clear slot caused by the rear flank downdraft made it easy to pinpoint where a potential tornado would form. A likely funnel cloud can be seen just above the distant group of trees. But even though conditions in the upper atmosphere were more than enough to support a tornado, the winds at the surface were too weak. I followed the supercell for most of it's life cycle but nothing ever touched down.
