Millions threatened by 'dangerously cold' wind chills

(CNN)The good news: the major storm that gripped the East Coast is moving away. The bad news: the Northeast is not out of the woods. A one-two punch of powerful winds and bitter cold are expected Friday into the weekend in the East and Midwest, with temperatures plunging as low as single digit during the day, and below zero at night. With wind chill, temperatures could be as low as -15 in New York and -25 in Boston on the weekend, according to CNN Weather.
