The National Weather Service latest projected snowfall probability outlook has a good portion of the Chicago area (mainly along and south of Interstates 88-290) in a better than 70% chance of greater than 8-inches of snow (area circled in red line above) from 6PM CST Saturday until 6PM CST Sunday.

The rest of the Chicago area (encircled in green line) calls for a better than 40% chance of 8-inches or more.

The map below shows probabilities of 4-inches or more for the same time period (6PM CST Saturday to 6PM CST Sunday) – a large area, encircled by a red line, includes all of the Chicago area as well as extending from Iowa through Illinois and Indiana into Ohio including southern Wisconsin and southern Lower Michigan in a better than 70% probability area.

This snowfall will be enhanced along and inland of Lake Michigan by the anticipated strong northeast winds creating additional lake-effect snow that will not only enhance system snow, but add additional snowfall near the lake later Sunday night and Monday as the low pressure system draws away from our area and system snow ends from west to east.
