More thunderstorms on the way tonight- Flash flood watch just issued for north portions of the Chicago area from late tonight through early Sunday morning

North portions of the Chicago Metro area are still waterlogged in the wake of heavy rainfall that soaked the area Wednesday night and Thursday night in the wake of rainfall that totaled 3-9 inches. Water tables are high and many area rivers and streams are in flood. A weather disturbance approaching from Iowa will bring another round of showers and thunderstorms late tonight into Sunday morning. Rainfall is expected to be heavy in many locations, aggravating the already tenuous flood situation.  Areas covered by the flash flood watch are generally along and north of I-88 across northern Illinois and include the following counties… Winnebago, Boone, McHenry, Lake, Ogle, Lee DeKalb, Kane, DuPage, and Cook including the city of Chicago
