June 11th was highly advertised as a big tornado potential day. Shortwave energy was ejecting from the high plains and would interact with a boundary from northern Kansas through Iowa and Minnesota. By the end of the day, several fatal tornadoes would occur, with the most noted being the Little Sioux, Iowa tornado and the Manhattan, Kansas tornado. We chased in Iowa this day and intercepted several storms that had tornado warnings, including the Little Sioux storm, which was quite messy and rain clogged.
