This page houses climatological snowfall data for the NWS Chicago County Warning Area (CWA), a 23 county area that includes a large portion of northern Illinois and northwest Indiana.  Much of the information is for two official climate sites, Chicago and Rockford, as these locations have longtime, quality-controlled climate data.
