According to the National Weather Service, Thursday’s rainfall was the most ever recorded on March 30 in Chicago, breaking the old record of 1.36 inches in 1949.
The precipitation also was the most rain in one day in Chicago since Sept. 18, 2015, and the most on a calendar day in march since March 19, 1948, when 2.5 inches fell.

A flood warning also was issued for the Des Plaines River near Des Plaines from Friday evening until Saturday morning. As of Thursday night, the river was at 14.1 feet, approaching the flood stage of 15 feet, and expected to continue rising through Friday evening, due to runoff in the area.
