CHICAGO (CBS) — More showers and thunderstorms soaked Chicago on Thursday, prompting more flood advisories and warnings.

The severe weather from Wednesday has moved out of the area, but steady, driving rains and brisk northerly winds greeted Chicago area residents on Thursday morning. Temperatures started in the 40s and are only expected to rise into the 50s–about 20 degrees below normal.

Yesterday’s storms grounded more than 800 Chicago area flights and airlines will be scrambling to catch up on Thursday morning.

Flood advisories have been issued for the east branch of the DuPage River at Bolingbrook in Will County and the Des Plaines River at Riverside in Cook County, according to the National Weather Service. Both rivers are expected to rise Thursday as rain continues.

Officials also issued a flood warning for the Kankakee River in Lake and Newton counties in Indiana, the National Weather Service said. The river is forecast to rise above flood stage by Thursday morning, causing minor flooding and continuing to rise to near 10 1/2 feet by early Monday. The river was measured at 8.9 feet deep Wednesday night.

Boaters are also warned to take caution, as 10 to 15 foot waves and 35 mile per hour winds are forecast for nearshore Lake Michigan waters, the weather service said. A small craft advisory is in effect until 10 a.m. Friday.

On Wednesday, clean up crews were hard at work clearing away debris and salvaging whatever property they could in St. Anne, ill. after a tornado ripped through the area near Kankakee.

After the storm left St. Anne it followed a Northerly path across farm fields.

In Pembroke Township firefighters drove the streets sounding the alarm. Deborah Michniak watched it approach .

“All of a sudden we seen the tail come down and my husband said oh my god it’s a tornado,” said Michniak.
