The 1 million revelers expected to flood Times Square on Sunday night are in for a seriously frigid start to 2018. CBS News reports the current forecast of 11 degrees with a wind chill close to zero will tie 2017 with 1962 for New York City's coldest New Year's Eve celebration. The coldest ever was in 1917, when it was 1 degree at midnight. With people expected to start gathering up to nine hours before the ball drops, the Today show's Al Roker has some suggestions for keeping warm. "Folks should start with a base layer of long underwear of merino wool and then use a number of lighter layers, finishing with a good warm coat," he tells USA Today. He also warns that while "booze may go down all warm and tingly," it will ultimately make "you feel colder." So keep that champagne corked until, let's say, August. (More New Year's Eve stories.)
