CHICAGO -- A  southwest/northeast-oriented jet stream flow aloft along with an upper-air impulse embedded in the flow will spread a band of snow across the Chicago area Wednesday morning.

As the impulse ripples off to the northeast, snow should end from south to north early Wednesday afternoon.

Heavier snowfall will reduce visibility to under a mile with minor accumulations, on the order of an inch or so mainly west and north of Chicago with lesser amounts southeast. Greater snowfall may occur along and farther north of the Illinois/Wisconsin state line.

The morning commute could be impacted to some extent, so be aware that visibility will lower and snow will stick, causing some slick travel conditions.
