Iowa Department of TransportationHourly weather forecast data for each of the 99 Iowa counties for the next 32 hours. Data is updated every hour. This service was designed to support the Iowa DOT WeatherView site. Data is provided by Schneider Electric WeatherSentry product. The weather data provided here by the Iowa Department of Transportation only reflects conditions at the specified site. Because of Iowa weather patterns, conditions can vary greatly in a small area; i.e., weather conditions a few miles away from the sensor could be completely different. In addition, failure of the sensors, or the equipment processing the information, may occur and produce unreliable information. Therefore, this information should not be used as the only factor in determining whether to travel in a particular area. The Iowa DOT recommends you check a number of sources, including media weather reports, in making your travel plans.ArcGIS FeatureLayerhttps://hub.arcgis.com/datasets/cb3fc60d5efb476da4644ceb0449b7de_0engIowaDOT Open DataPublicCounty Forecast Data - Iowa Only [Iowa]Web servicesIowaLast Modified: 2026-01-08
