The episode as NWS DVN wrote it up.
Rain developed throughout Eastern Iowa and Northwest Illinois ahead of an arctic cold front which swept across the region. By late afternoon the rain began to change to snow as colder air overspread the area. The snow mixed with sleet and freezing rain at times, mainly along and south of I-80. Roads became slick and snowpacked north of I-80 resulting in treacherous driving conditions and numerous accidents. Most of the snow fell in a swath from Iowa City to Dubuque and Freeport where accumulations ranged from 1 to 3 inches.
