A significant winter storm is forecast to affect the entire state of Iowa beginning late today and continuing through Saturday night, according to the latest briefing from the National Weather Service (NWS) in Des Moines. Widespread accumulating snow is expected, creating hazardous conditions during one of the busiest post-Thanksgiving travel periods. Snow will begin moving into western Iowa late this afternoon and spread across the state overnight. The heaviest snowfall and worst travel conditions are anticipated on Saturday, particularly from early morning through late afternoon, before the system gradually exits by late Saturday night.
Forecast snowfall totals vary across the state, with central and northern Iowa likely to receive between eight and twelve inches or more. Southern and southwestern Iowa may see slightly lower totals due to periods of mixed precipitation, including rain, which could reduce snow accumulation in those areas. Even where totals are lower, travel disruptions remain likely due to persistent snowfall, potential icing, and reduced visibility. Snowfall rates could reach up to an inch per hour at times on Saturday, especially in northern and eastern parts of the state.
The impacts from this storm may be substantial. Travel is expected to become difficult and potentially dangerous across much of Iowa, particularly on Saturday when snowfall is heaviest. Slick roads, limited visibility, and drifting snow will pose hazards for motorists, and holiday travelers are encouraged to prepare for delays or consider postponing travel if possible. As temperatures drop following the snowfall, cold conditions may create additional challenges for snow removal efforts and could threaten vulnerable populations.
Residents, travelers, and local partners are encouraged to prepare accordingly. Those who must travel should allow extra time, slow down, and bring a winter emergency kit. Communities should be aware of any local snow ordinances or emergency declarations that may go into effect. The NWS Des Moines office will issue its next briefing around 6 PM today, and all partners are encouraged to monitor updates closely to stay informed about changes to the forecast or impact timing.
