The episode as NWS DVN wrote it up.
During the period of January 12-15, 2007 an arctic cold front moved slowly through the region, bringing a shallow arctic airmass. The front became nearly stationary across central Illinois, while several upper level disturbances moved along the boundary. This set up several rounds of freezing rain, sleet and snow that affected eastern Iowa, northwest and western Illinois and northeast Missouri. The main upper level trough then pushed through the region late in the period, bringing colder air with it, and changing the mixed precipitation to all snow. By the end of the event, northeast Iowa received 2-4 inches of snow, eastern Iowa and northwest Illinois picked up 1-3 inches of snow, along with ice accumulations of less than 1/4 inch. A portion of northeast Missouri into western Illinois was plagued by an ice storm, with 1/4 to 3/4 inch ice accumulations.
