It may not have felt very cold in most of the U.S., but in Central and Eastern Europe a brutal cold snap has killed at least 48 people so far. Ukrainian authorities say 30 people have died of hypothermia in recent days alone. Temperatures in Kiev are 10 below zero Fahrenheit and are projected to be about two below in Moscow today. It's normally about 18 degrees in Moscow at this time of year. In Prague, where the cold has also damaged train tracks, authorities are setting up tents for an estimated 3,000 homeless people.
