1. Alaska

Not surprisingly, the country's northernmost state takes the cold temperature crown. With numbers from just this year lower than half the country's all-time lows, Alaskans have every right to say, "You don't know what cold is, son."

This year's low*: -41

*Data collected Dec. 30-Jan. 19 by the National Weather Service, including only weather stations that have already reported these weeks. All temperatures are in Fahrenheit.
