In their Inaugural season, the Thunder became the first team in Iowa history to have a winning record at 5-3 and followed that up in 2010 with a 6-2 campaign that left them tied for 1st in the division (although they lost the tiebreaker to the Minnesota Machine based on head-to-head points total) and the first ever team to garner a playoff berth. The Thunder defeated the Machine 20–12 in the first round, but lost to the eventual WFA champion Lone Star Mustangs 30–20 in the conference semifinals.
