The Iowa Department of Transportation maintains a set of observing stations located along major roads in the state. These stations measure pavement temperatures as well as atmospherics. The DOT has a good website called WeatherView, which contains recent obs and a wealth of other information. The products on this page are intended to supplement their site.
