No more rain is expected until Memorial Day after severe thunderstorms dropped down on the area Tuesday, causing several flight cancellations.
But areas south of Interstate 80 could still see some thunderstorms and golf ball-sized hail Wednesday morning, according to a hazardous weather notice from the National Weather Service.
There is a 20 percent chance for rain that is forecasted before 8 a.m. for Chicago. But areas south of I-80 face a significantly higher risk of seeing more storms, paired with wind gusts of 60 mph, the weather service said.
Heavy rainfall Tuesday dropped a .84-inch of rain at O’Hare International Airport, National Weather Service Meteorologist Matt Friedlein said.
Areas in the south suburbs saw heavier rain, Friedlein said. Lansing logged 1.3 inches for the duration of the storm, starting at 4 p.m.
The weather caused more than 115 flight cancellations at O’Hare and halted all Midway flights at 8:30 p.m. Tuesday. Any cancellation or delay information for Wednesday was not yet available at 5:30 a.m.
Suburbs saw flooding Tuesday night, including Oak Forest, where several roads were under water.
“We had two or three inches of rain that fell in a very short time that backed up sewers and people are driving into deep water getting their cars stuck,” said an Oak Forest Police officer Tuesday night, who did not give his name. “We even have squad cars stuck right now.”
The storms walloped the western suburbs as they moved across northeastern Illinois.
North Aurora and Naperville residents reported 1-inch hailstones and as much as 6 inches of standing water on some streets and under viaducts, the weather service said.
Water was receding Wednesday morning in Naperville, and all roads were open, police said.
In North Aurora, about 6 inches of water was standing on North Aurora Road, just east of Eola Road, and drivers are being told to drive carefully through the roadway, police said.
Back in Chicago, temperatures on Wednesday are expected to stay warm, but muggy, with a high near 80 degrees and 87 percent humidity, the weather service said.
And the better news is that no rain is expected in the city until Memorial Day, the weather service said.
