Des Moines, IA – Snowfall from a major winter storm has already begun across Iowa, ushering in a prolonged period of heavy snow that will continue through most of Saturday, according to the National Weather Service (NWS) in Des Moines. A Winter Storm Warning remains in effect for nearly the entire state, including an expanded area across southern Iowa.
According to NWS forecasters, snowfall will intensify through the evening and overnight hours, with the heaviest snow falling from central into northern Iowa. Widespread accumulations of 8 to 12 inches are expected, with localized totals even higher where banding sets up. The snow will fall over a long duration, creating significant impacts for travel, visibility, and road conditions.
In southwest Iowa, a glaze of ice or a brief rain/snow mix is possible, adding to travel difficulties. The rest of the state will experience primarily heavy snow, accompanied by breezy winds that will lead to blowing and drifting snow—especially in rural areas and open fields.
NWS warns that road conditions will rapidly deteriorate, and travel could become difficult to impossible at times. The agency urges residents to consider delaying or canceling any travel plans. Those who must be on the roads should pack an emergency kit, use caution, and allow extra time to reach their destination.
The timing graphic shows storm impacts peaking through Saturday, with the heaviest snowfall occurring from Friday evening into Saturday night. Hazardous conditions may linger into early Sunday as crews work to clear snow-covered roads.
Residents are encouraged to stay updated on the latest road conditions through the Iowa DOT and continue monitoring NWS updates as the storm evolves.
