The Chicago area on Monday saw its largest snowfall of 2013, according to the National Weather Service.

As of 7:15 a.m., the weather agency said 2.6 inches of snow was recorded at O’Hare International Airport, the official measuring point for Chicago. The snowfall is expected to end about noon, the weather service said.

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

But even with the snow accumulation, the area’s precipitation is still well below the yearly average, 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.”
