Many winter weather advisories have been issued through noon Sunday for light freezing rain, and for snow in northern Illinois/Indiana.
Rough areas of where we see snow/freezing rain/rain and general time-frames posted on this graphic below. Important to note that patchy drizzle will be possible ahead of these main time-frames.
Here is the latest thinking on snow amounts: 3-5″ over north-central Illinois, 4-7″ in far northern Indiana.
