Utica – Dwight, IL

July 13th, 2015, was a great chase day for a number of reasons, although not one that yielded tornadoes. I flew into Madison, Wisconsin, to meet up with Alex, Adam and Adam, planning to chase Northern Illinois that afternoon. Morning convection would leave outflow boundaries draped across the region that would later provide a focus for supercell development in an extreme CAPE environment. SPC extended a moderate risk from Eastern Iowa, through much of Illinois and Indiana, with a 10% hatched area for strong tornadoes across the Illinois portion. Liking the area extending between Davenport, Peoria and Bloomington, we set our initial target as Galesburg and headed out.
