The National Weather Service says a “multifaceted storm system” is expected later this week and the potential exists for over six inches of snow in northern Illinois.
The National Weather Service (NWS) said Wednesday that the system will move into the region late Thursday night through Friday.
A dry cold front is shifting into the area Wednesday and it will result in cooling temperatures for the second half of the week.
Accumulating wet snow, heavy rainfall and strong northeasterly winds are the main concerns across the region with the incoming storm system.
The potential for accumulating wet snow is likely across much of northern Illinois, the weather service said.
A band of over six inches of snow is possible in far northern Illinois.
Forecasters are still uncertain exactly which areas will see the highest amounts.
Most of Lake County and McHenry County have a “medium” probability of receiving over three inches of snow, according to a graphic released by the NWS.
Over six inches of snow in the two counties are also possible. High winds may gust at more than 40 mph areawide.
The storm has the potential to significantly impact travel, the NWS said, adding that updates will be released when available.
