The National Weather Service has issued a winter weather advisory for blowing snow, which is in effect until 4am Tuesday.
Light snow and blowing snow will occur behind a cold front that is moving through north central Iowa this evening. Gusty northwest winds will rapidly increase which will allow visibilities to rapidly decrease in the snow and blowing snow. Accumulations will be less than one half inch, with visibilities around one half mile or less.
Air temperatures will fall from zero to 5 below zero by daybreak on Tuesday will little recovery during the morning. Wind chill values will generally range from 20 to 25 below with slightly colder readings along the Minnesota border.
Roads may quickly become slick due to blowing and drifting snow causing hazardous travel conditions. Frostbite can occur within 30 minutes to exposed skin with these types of wind chill values.
