(Undated) -- Road conditions have been worsening throughout the day today, (Monday) due to a winter strong. Forecasters say a large part of Iowa could get nearly a foot of snow with this system.
From the National Weather Service in Des Moines:
Heavy snow will continue across much of central and southern Iowa into the night. Snowfall rates of 1-2" per hour are likely at times with widespread 6-13" accumulations from Highway 20 south to the Missouri border. Snow totals of this magnitude are somewhat rare, only occurring once every 15 to 20 years so impacts will not be common. Northeast winds may gust to around 30 mph producing blowing snow and dramatically reduced visibilities. This combination of snowfall rates and wind may produce near whiteout conditions, especially in open areas. Multiple tow bans are already in effect. Travel will likely be quite difficult if not impossible at times into tonight. Improvement is anticipated by Tuesday morning with winds diminishing somewhat and snow ending.
