A short period of drizzle/freezing drizzle is psbl in the highlighted area tonight-early Thurs AM. There is potential for some icy spots on area roads. Plan for slick driving conditions late tonight-early Thurs AM.

More on the rain that caused this, which was the 2nd largest Feb rain event on record for Chicago & its largest winter rain event in 21 years: https://t.co/5Opj7opoUd… #ilwx #inwx pic.twitter.com/nk8SbEk6f9
Much or all of precip tonight-early Thu should be confined mostly south of IL & Kankakee Rivers. Precip, if it occurs, will be either light freezing rain or sleet mixing with snow. Wintry mix should be short lived. Stay tuned for updates. #ilwx #inwx pic.twitter.com/SkmhJhg41v— NWS Chicago (@NWSChicago) February 22, 2018
Here’s the Little Calumet in S Holland (Cottage Grove Ave) at 3:30 pm today. The chain link fence on the right in the left photo is the bank. pic.twitter.com/nqL4zwumKP— Susan Przybylo (@SusanPrzybylo) February 21, 2018
If you see a barricade -- DON'T GO AROUND IT. We have some roads (as pictured here on SR 331) where the record-rainfall has washed away parts of the pavement. You may think the road is safe because you don't see water. But those barricades are there for a reason. #BeSmart pic.twitter.com/RKcewKw4AN— INDOT Northwest (@INDOTNorthwest) February 21, 2018
Here is a look at rainfall totals over the 60-hour period from Sunday evening through early Wednesday morning. Totals from select volunteer observers are listed for each county across the NWS Chicago forecast area. pic.twitter.com/A8ac6K5kLG— NWS Chicago (@NWSChicago) February 21, 2018
