A strong storm system that brought snow as far south as the Gulf Coast of Texas crossed the Great Lakes region February 15th into the morning of the 16th. Though northern Illinois was on the northwest extent of the main axis of heavy snow with this system, lake-effect and lake-enhanced snow resulted in significant snow totals along and near Lake Michigan in Illinois and Indiana, where amounts in excess of 12" were common, with isolated pockets of up to 18". A substantial snowfall gradient was centered roughly along the I-294 corridor in Cook County, with a difference of up to 10 inches over as little as 5 miles (7.1" in Elmhurst and 18.2" in Oak Park.)
