Iowa — Wind chill indices dipped as low as 20 below zero in parts of northern Iowa this morning, with air temperatures in many cities in the negative teens.
National Weather Service meteorologist Cory Martin says this is likely the coldest air Iowans have endured since last January, and more scattered snow is on the way.
That freezing rain translates to black ice on roads and Martin says driving may quickly become hazardous.
The forecast calls for the precipitation to end later Saturday while Sunday should be dry with highs that are decent for December in Iowa in the 30s and 40s.
