With the severe weather threat having ended across the Chicago area, attention turns to snow overnight that will make for a slippery morning commute. Wet snow showers will increase after midnight and become widespread overnight. Snow showers may linger through 8 a.m., especially for Northwest Indiana.

Officials said there was a 60% chance of showers and a thunderstorm  possible by 2 p.m. Wednesday in portions of north central and northeast Illinois and northwest Indiana.

A band of severe weather brought tornado warnings to the Chicago area and parts of northern Illinois on Wednesday, downing power lines and knocking power out to homes. Thursday morning's commute will be chilly,
