DES MOINES, Iowa - The National Weather Service is warning the public about extreme conditions moving into Iowa Friday into Saturday.
Widespread snowfall moves into the state this morning and continues through the afternoon hours. The snowfall will be heavy at times. Expect quickly worsening travel conditions due to slick roads and limited visibility from blowing snow. Much of the state will receive 4-6 inches of snow, including metro Des Moines. Parts of northwest Iowa will see 6-8 inches. Accumulations of 3-4 inches are likely along a line straddling I-80 southward, and extending from Council Bluffs to Davenport across the state.
Snowfall will change to freezing rain or drizzle by late this afternoon and evening. Icing of up to a tenth of an inch may be common across the area through tonight. The icing combined with high winds could lead to downed power lines.
Some light snow may linger into Saturday, but meteorologists are more concerned about very strong winds and the potential for blizzard conditions, mostly in the northwest part of the state. A blizzard warning has been issued for northwest Iowa white-out conditions are expected with near impossible travel at times due to blowing snow. Strong winds will still cause areas of blowing snow and hazardous travel in central and southern Iowa, although blizzard conditions are unlikely.
