While a snowfall event is likely for the northern parts of the area, the far south and southwest suburbs may see a freezing rain event that could lead to some ice accumulation.

North of the Illinois-Wisconsin border, up to eight inches of snow are possible before Sunday morning as the system moves to the north throughout the day.

The Saturday system comes after multiple bursts of snow this week in the Chicago area, which had seen a snow drought in the weeks before.

While some snow showers may linger, Sunday is expected to remain mostly dry.

Additionally, temperatures are expected to drop, with highs reaching only into the upper 20s and falling in the days following the storm.
