Chicago-area roads were expected to get slick and slippery and travel impacts were likely for the Thursday morning commute as a winter weather advisory with bursts of "wind-whipped" snow moved into the region.
According to the NBC 5 Storm Team, all of Northeastern Illinois is expected to see waves of snow showers Thursday morning, beginning around 7 a.m., with two to four inches of accumulation possible. Slushy snow totals were expected to partially melt as temperatures rise above freezing, the NBC 5 Strom Team said.

Accompanying the snow will be wind chills in the teens and 20s, with gusts as high as 40 or 50 miles-per-hour at times. According to the National Weather Service, a wind advisory will go into effect at 10 a.m. for the entire area.
According to the NWS, sharply reduced visibility was expected for the morning commute, with accumulating snowfall "likely" to impact travel. Highest snowfall rates were expected to start around 8 a.m., the NWS said, lasting through Tuesday afternoon.
The heaviest snow was expected to fall first close to the Illinois-Wisconsin border as a band of heavy snow started to creep down from Green Bay.
