July 13th was the second great day for the Great North Tornado Hunt tour. We started the day in Wichita. Extreme heat and instability would form that afternoon with temperatures near 100F and dewpoints in the upper 70s. Cells tried to form for a couple hours along a dryline/outflow boundary composite, and finally by around 5pm a significant supercell formed just west of Arkansas City, KS. This storm quickly became severe for large hail to tennisball size. As it continued to intensify, it moved due south towards northern Oklahoma near Peckham. This storm was a striated beast. It had continuous lightning, huge hail to baseball sized, and a wall cloud that spun like crazy. By mid evening, the storm weakened as it merged with other cells to its west, and eventually lined out moving into central Oklahoma. One of my favorite nontornadic chases of 2016!
