An intense lake-effect snow band is expected to develop tonight and move in from Lake Michigan. While not unheard of to at least get flurries this far south due to the lake, accumulating snow is more rare. Areas near Champaign and Danville are most likely to see this occur, mainly after midnight tonight, with about a 20-40% chance of at least an inch of snow. Lake-effect snow bands are very tricky to forecast in advance, as the angle of the wind off the lake plays a big role. The Chicago area is expected to be hit hard by this lake-effect snow, and travel conditions northward along I-57 will deteriorate rapidly.
