The National Weather Service has extended existing winter weather advisories for all of northern Illinois and northwest Indiana, with snow expected to hamper traffic during the morning commute in most places.
According to the latest guidance, the advisory will go into effect at varying times across the area, with 1 to 6 inches of snow possible by Wednesday evening, with parts of central Illinois and central Indiana seeing the heaviest accumulations.
The new warning will go into effect at midnight in LaSalle, Kendall, Grundy, southern Cook, Will and Kankakee counties in Illinois, and Lake, Porter, Newton and Jasper counties in Indiana.
Illinois counties will remain under this warning until 6 p.m., as will Newton and Jasper counties, according to the warning. Areas closer to Lake Michigan, including Lake and Porter counties in Indiana, will remain under the warning until midnight Thursday.
While accurate snowfall forecasts are still being compiled, the National Weather Service says the highest accumulations are likely to occur in central Illinois and Indiana, with Lake, Porter, Newton and Jasper counties potentially seeing 3 to 6 inches of snow , with some local – higher amounts possible.
In Illinois, areas south of Interstate 80 could see between 2-4 inches of accumulation, with the morning commute largely affected by the snowfall.
Lake and DuPage counties, as well as northern and central Cook County, will go under the advisory at 3 a.m. and remain under the advisory until 9 p.m.
Those areas closer to the lake could see slightly higher accumulations, with 2 to 4 inches of snow possible.
Finally, McHenry, DeKalb and Kane counties will be under curfews from 3 a.m. to 3 p.m. Those counties should see less intense accumulations, but road conditions Wednesday morning could still be hazardous.
Wednesday’s snowfall is the first of several disturbances that could bring wintry weather to the area, with another shear system expected to arrive Friday and several new rounds of snow possible Saturday and Sunday, according to the NBC team 5 Storm.
