Overview
|
Two rounds of showers and thunderstorms tracked across northeast Iowa and northern Illinois Sunday morning and early Monday morning bringing torrential rain and occasional lightning to the region. Rainfall amounts over 2 inches were common northeast of a line from Cedar Rapids, to De Witt, to Prophetstown IL. The highest amounts between 5 and 11 inches fell in eastern Jo Daviess and Stephenson counties in northwest IL. This caused numerous road closures in the county and floodwaters impacting homes in Freeport, IL. |
