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.
Conditions are entered by Iowa DOT maintenance staff and describe what is on the pavement, not the forecast; what each term means is on the Iowa page. Always check with Iowa 511 before setting off.

NOAA 1991–2020 Climate Normals, from a weather station in Iowa. A dash is a figure that station does not report, not a zero.
From Lamoni to Clear Lake, with the position of each town measured along this stretch itself — counted from the Lamoni end, not from a state milepost, so it will not match the numbers on the signs.
Places from the US Census Gazetteer and population estimates, both public domain; distances measured along this page's own route geometry.
