As of noon, 2.9 inches of snow had been recorded at O'Hare International Airport, the official measuring point for Chicago, NWS spokesman Matt Friedlein said. The snowfall ended at 9 a.m. at O'Hare and by 10 a.m. throughout the area, he said.

The snow caused slick conditions on roads during the morning rush, with at least 25 accidents reported on area expressways, Illinois State Police said. In Chicago, the city's full fleet of 284 snowplows were salting and clearing streets.

Light lake effect snow is expected periodically throughout the area through early Monday evening, Friedlein said.

Another inch to 1½ inches are expect to fall Tuesday between 9 a.m. and 3 p.m., with the heaviest snowfall expected in Lake County and northern Cook County, Friedlein said.

Tuesday's snowfall will mark the fifth straight day of accumulated snowfall in the city, Friedlein said.

But even with the snow accumulation, the area's precipitation is well below normal, said Amy Seeley of the National Weather Service, adding that the effects of last summer's drought are still being felt throughout the area.

"This seems like a big deal, but we're still well below our snow normals," she said. "This isn't going to do much."
