A deep freeze across the Midwest set in Sunday with single-digit temperatures - and a few below zero - turning the season's first major snow into ice that made some roads treacherous to travel.

Temperatures plunged to 20 degrees or lower across six states from North Dakota to Illinois behind a cold front that brought snow across much of the region Friday and Saturday. 

The National Weather Service reported temperatures in the single- and low double-digits Sunday in northern Illinois, including Chicago, where residents were digging out of about 11 inches of snow.

The first snowfall of the season also brought amounts ranging from a few inches to 20 inches of snow from South Dakota through Michigan earlier in the weekend.

In the southern Wisconsin town of Janesville, between ten and 20 inches of snow had fallen by late Saturday afternoon, according to the National Weather Service.

Southside True Value Hardware manager Matt Krienke said business had been good in the days leading up to the storm in the Janesville, but that it had become 'very, very, very, very slick.'

'People who don't need to drive don't need to be out,' he said. 

Slick driving conditions were reported across the region. 

In western Michigan, two people were injured in a 15-car pileup late Saturday along Interstate 196 following heavy snow in the area. 

Local police said one woman was struck by a vehicle after getting out of her vehicle.

Snow totals in the northern suburbs of Chicago topped initial forecasts of six to ten inches, said National Weather Service meteorologist Amy Seeley - 12.5 inches in Woodstock and 11.7 inches in Roscoe. 

It's unusual for the area's first snowfall of the season to dump more than six inches, Seeley said.

About 60 miles northwest of Chicago, the village of Capron had received 14.6 inches by Saturday morning, spurring village employee Robert Lukes into action clearing sidewalks with his snowblower in the community of about 1,400 people. 

He said the snowfall was wet, with a layer of slush underneath that made the work slow going. 

'It's a typical first snow for us, but it's a pain in the butt. There's quite a bit of it and it's kind of difficult plowing and snowblowing,' he said, adding, 'It's just another snowstorm in northern Illinois.'
