IOWA CITY, Iowa Snow is falling across much of Iowa, and forecasters predict much of the state will be covered by 2-4 inches of snow by Sunday night.
The National Weather Service says this is the first widespread snow storm of the winter for the state.
A section of Interstate 80 in Des Moines was closed for more than an hour Sunday morning because of a 20-car pileup. No serious injuries were reported.
Shortly after 1 p.m., a large crash was reported along I--80 in Iowa County. The crash blocked both westbound lanes of the interstate.
Southbound Interstate 29 was closed in Sioux City around midday Sunday because an accident was blocking the lanes.
The Weather Service says wind is expected to cause additional travel problems later Sunday by blowing the snow around.
