Official Illinois road conditions (Getting Around Illinois) ↗
26 current reports along the route, including 1 full closure. The 8 most serious are listed below. Always check with the responsible state DOT before setting off.
Winter reporting is off for the season. Iowa DOT's Winter Road Conditions – Midwest Region feed, which carries Illinois DOT's segment-by-segment snow and ice conditions, runs from October 15 to April 15; outside that window it changes only as needed. Our own forecast below runs year-round.
Illinois DOT's winter road conditions reach this page through Iowa DOT's Winter Road Conditions – Midwest Region feed, which runs from October 15 to April 15 and refreshes every 10 minutes. That feed is published for reference; the authoritative report is Getting Around Illinois. Conditions are entered by maintenance staff and describe what is on the pavement, not the forecast. This page shows those reports next to our own road-surface forecast. Always check with Getting Around Illinois before setting off.
Each stretch has its own live conditions, closures and cameras for the Illinois miles only — the weather 500 miles away on the same interstate says nothing about this drive.

NOAA 1991–2020 Climate Normals, from 4 weather stations in Illinois. A dash is a figure that station does not report, not a zero.
Snowfall across Illinois is not one number: Springfield averages 20.9" a year and Chicago averages 37.1".
What the road normally throws at you, month by month, from NOAA's 1991–2020 normals for Illinois's own stations. Each month names its dominant hazard and the place that measured it — this is what the month is usually like, not a forecast and not a restriction.
