CHICAGO — Accumulating snow is forecast to overspread the entire Chicago area beginning early Wednesday morning.

A Winter Weather Advisory has been issued for the Chicago area for Wednesday.

It is set to begin at 3 a.m. and run through 3 p.m. for Winnebago, Boone, McHenry, Ogle, Lee, DeKalb and Kane counties and through 9 p.m. for DuPage, Lake, Cook counties in Illinois.

The snow is expected to impact the morning commute area-wide with three to five inches likely. Snow is to begin in Wednesday’s pre-dawn hours and is likely to continue through a good chunk of the day. Lingering flurries are expected Wednesday night into Thursday with some more substantial lake effect snow showers not out of the question.

How much snow will we see?

Five to seven hours of steady snow with flurries continuing beyond that is to fall across the western suburbs and as many as 10 to 14 hours of snow is to fall in lakeside locations, where some lake enhancement is likely. That’s hardly a superstorm by January standards but it’s enough to produce slippery travel.
