What is the coldest spot in the nation?

Generally speaking, the coldest state in any given month is Alaska. It is interesting to note, however, that Nevada is the state with the all-time largest temperature spread, with the highest temperature to lowest temperature in one year. In 1984, the temperature spanned from 50 degrees below zero F in January, to 125 degrees F in June, a range of 180 degrees that year. South Dakota is next with a span of 177 degrees.
