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.

Conditions are entered by Illinois DOT maintenance staff and describe what is on the pavement, not the forecast. They reach this page through Iowa DOT's Winter Road Conditions – Midwest Region feed, published for reference; the authoritative report is Getting Around Illinois.
