Overview

Scattered thunderstorms quickly became numerous along the I-88 corridor on the early afternoon of Friday, July 29th.  These were extremely slow moving, leading to large totals in a short amount of time.  With antecedent wet conditions, this rainfall brought flash flooding to DeKalb, Kane, DuPage, and Cook Counties.  Some of the flooding persisted into the day after.  In addition, the DuPage River at Bolingbrook reached a top 10 crest in its ~20 year period of record.
