Winter reporting is off for the season. Iowa DOT publishes segment-by-segment snow and ice conditions from October 15 to April 15; outside that window the feed changes only as needed. Our own forecast below runs year-round.
Iowa DOT reports winter road conditions from October 15 to April 15 on the interstates, U.S. and state highways that Iowa DOT maintains, not county roads or city streets. Crews update a report every two hours or as conditions change, and the feed this page reads refreshes every 10 minutes. 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 Iowa 511 before setting off.
Each stretch has its own live conditions, closures and cameras for the Iowa 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 Iowa. A dash is a figure that station does not report, not a zero.
Snowfall across Iowa is not one number: Cedar Rapids averages 26.7" a year and Des Moines averages 35.3".
What the road normally throws at you, month by month, from NOAA's 1991–2020 normals for Iowa'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.
