Winter weather advisories have been issued for several Chicago-area counties in advance of a winter system set to bring snow cover and “unsafe” travel conditions to parts of the area.

The advisory was issued to LaSalle, Kendall, Grundy, Kankakee, Southern Cook and Will counties in Illinois, and Lake and Porter counties in northwestern Indiana.

Beginning at midnight CST and continuing until 6:00 pm Wednesday, it warns of 2 to 4 inches of snow and “slippery” road conditions that could make Wednesday morning’s commute dangerous.

Newton and Jasper counties in Indiana simultaneously issued another advisory warning for deposits between 3 and 5 inches.

Predictive models show the system moving up from the south, resulting in heavy snowfall Wednesday night.

According to the National Weather Service, “worsening travel conditions during Wednesday morning’s commute” are expected, with peak snowfall occurring in the morning.

By lunchtime, however, forecast models show a reduction in the snowfall rate. Additionally, temperatures are expected to rise and reach the late to mid-thirties.

The NBC 5 Storm team notes that the area is lacking and near below average snow, so the system indicates a return to typical January weather for the Chicago area.

The Chicago area may see snow throughout the region, but the highest totals are expected in areas south and east of the city.

According to the NBC 5 Storm Team, it is expected to be less than 2 inches in northern counties, up to 4 inches in southern and southeastern suburbs, and up to 5 inches in northwestern Indiana.

By Wednesday evening, the system is expected to start massing out of the Chicago area. However, because Lake Michigan’s waters are warmer and winds are blowing from the north, lake-effect snow can affect areas south of the lake in northwestern Indiana.

As a result, parts of Indiana could see locally higher total snowfall by Thursday morning, according to forecast models.

Another winter weather could arrive in the form of a fast-moving Clipper system on Friday, which could bring light snowfall or mixed precipitation to the region. would be on the lighter side.

Predictive models expect more snow late Saturday into Sunday as the two air masses collide with each other. Light snowfall is likely as these air masses pass over the Midwest, bringing additional accumulation to areas that see snow over several days.
