Repeated Downpours Could Lead To Flooding For Chicago Area

A localized flooding threat is possible across the Chicago area, with repeated downpours possible Friday afternoon through Saturday morning, according to the National Weather Service.

The weather service said there is a chance of storms on Friday afternoon and night, and a few of the storms "may approach severe limits."

Temperatures will cool into the 70s over the weekend, with a high of 84 on Friday, 75 on Saturday and 78 on Sunday, according to the current forecast.

There is also a chance of storms on Saturday, but severe weather is not expected.

Repeated downpours could lead to localized rainfall totals in excess of two inches. Flooding of low-lying and poor draining areas is likely, and rises in river and creek levels may occur as well, the weather service said.
