This was a long duration event made up of several components, and even sort of two events with the second being just lake effect snow. There was a period of snow on Sunday morning, the 17th, followed by snow and some ice during the afternoon. This led to hazardous travel. For the evening, the precipitation had all transitioned back to snow along and north of I-80, while remained freezing drizzle south. The snow gradually faded during the early morning of Monday the 18th. Lake effect snow showers though developed and persisted into far northeast Illinois and far northwest Indiana into the late afternoon. The longest duration snow was in far northern Illinois where the highest amounts fell. When accounting for the lake effect snow of the 18th, total amounts were highest in Lake County, IL and northern Cook County.
