Low pressure brought strong thunderstorms over Iowa and Illinois the evening of October 6th, 2016. Just ahead of the low's path, a warm front was positioned over Iowa and Illinois near Interstate 80. This allowed for winds supporting tornadoes to develop with the strongest storms. A cluster of strong to severe storms moved from near Ottumwa Iowa, northeast through Scott county, with several areas of damaging winds and tornadoes along the path from Louisa and Muscatine counties, through Scott county, and into portions of Rock Island county, Illinois before ending.
