The leading edge of the band of snow has crossed the state line and has moved into northern Illinois along a line from near Highland Park to Freeport . At Freeport in the northwest part of the state the visibility is down to 1/2 miles in moderate snow while at Rockford the visibility is 13/4 mile in light snow. Snow is also falling at Waukegan where the visibility has dropped to 2 miles and has just begun at Arlington Heights
Madison, Wisconsin received about an inch of snow when the snow band passed through, and visibilities in the Milwaukee area have dropped to 1/4 to 1/2 mile in the snow. An observer about 5 miles southwest of Madison measured 1.4 inches of snow.
A narrow band of moderate to heavy snow currently moving southeast through southern Wisconsin is headed for the Illinois border. At 11am the band of snow extended from the Milwaukee area southwest to Dubuque and was moving southeast at about 40 mph. The snow was reducing the visibility to as low as 1/2 miles in the areas of heaviest fall. Though not lasting long, a quick inch or two is snow is possible as the band moves through and it iwll create slippery roads and hazardous travel conditions.
