Frigid Temperatures Hit Chicago

CHICAGO (CBS) -- It only takes a step outside to experience just how cold it is as frigid temperatures are expected throughout the day Sunday.

CBS 2's Courtney Gousman reports Pacific Garden Mission on Canal operates 24 hours a day serving the city's homeless.

According to volunteers, on an average night about 500 people take shelter here. But on cold bitter nights like Saturday night that number can jump to 800.

Things were brutal for those who lined the Mag Mile for the annual lights festival Saturday night.

Adults and children were wrapped-up in their scarves, hats, and gloves. Of course, winter gear was flying off the shelves at Michigan Avenue stores as people realized how cold things were.

Any moisture on cars and on the roadways is freezing over.

Courtney Gousman talked to some people who shared secrets on how they make it outdoors for several hours in this weather.

"Hand warmers," said Brian Banks. "You put a few in your gloves and if you need, in your pocket or jacket."

To find out about city-run warming centers and their hours, dial 311. Operators say if you need a break from the cold, you can also take shelter at police stations, and libraries during hours of business
