An unseasonably intense low pressure system tracked from Wyoming to the Dakotas and then to northern Minnesota on June 7, 2007. A strong cold front moved across the region during the late afternoon and evening, which triggered scattered severe thunderstorms. Due to the very strong wind field associated with the storm system, and unstable air ahead of the cold front, damaging wind was the main event. However, some large hail was also reported. One of the hardest hit areas was Davenport where many trees and branches were blown down, along with scattered power outages. Also, a farmstead had several barns destroyed on the outskirts of Bettendorf.
