A strong weather system took an anomalous path for April 27 and brought a combination of widespread precipitation and cold air. This allowed for rain to change over to snow across northern Illinois and northern Indiana. Precipitation type at times varied, wobbling between snow and rain (even ice pellets in some places).  Snow at times was heavy, sharply reducing visibility causing patches of hazardous travel, and by late afternoon into evening causing accumulation on some roadways. With temperatures around freezing, slickness developed on some roads as well.
