...Lake Effect Snow Expected Near the Lake Late Tonight into
Sunday...

A band of lake effect snow will develop along the Wisconsin shore
of Lake Michigan this evening, then swing southward across the
northeastern Illinois and far northwestern Indiana shores after
midnight. This band of snow looks to remain progressive, which
should limit its duration at any given location across the far
northeastern Illinois shore. Nevertheless, some light
accumulations and slick travel may result in some localized areas
near the lake into early Sunday morning. The lake effect band is
expected to become focused across northwestern Indiana Sunday
morning, before shifting east of the area Sunday afternoon.
