A Weekend When 'Chilling Out' Takes On a New Meaning

Jan. 20, 2008 — -- As the Midwest and Northeast continue to endure freezing temperatures, the South is reeling from Saturday's snowfall.

A mix of rain and snow blanketed Delaware, the Carolinas, Alabama, Virginia, Georgia and Mississippi, with accumulations reaching up to four inches. In some areas, it was the first snowfall since 2001.

In Atlanta, the snow forced airlines to cancel nearly 340 flights at Hartsfield-Jackson, the nation's busiest airport.

Meanwhile, residents of the Plains, Midwest and Northeast are still experiencing the paralyzing cold snap.

Sunday morning, it was 32 below zero in Northern Minnesota, and 14 below zero in Minneapolis, where athletes from 200 teams are competing in the final day of the National Pond Hockey Championship on Lake Nokomis.

In Chicago, temperatures dipped to 3 below zero. Twenty warming shelters opened Saturday morning in various Illinois locations to protect the homeless from wind chills as cold as 30 below zero.

And at Lambeau Field in Wisconsin, where the Green Bay Packers and New York Giants meet tonight, the temperature at kickoff is expected to be around zero, with a wind chill around 20 to 30 below zero.

This NFC championship game probably won't be the coldest game in NFL history. In the 1981 AFC championship game, the Cincinnati Bengals and San Diego Chargers played in minus 9 degree weather with a wind chill that made the "feels-like" reading minus 59 at Cincinnati's Riverfront Stadium.

In the conditions forecast for tonight's game, frostbite can occur in 20 minutes without adequate protection. Emergency medical personnel will be roaming the stadium to watch out for fans -- and athletes -- who might be suffering from the extreme temperatures.
