The coldest it has been on this day in Anchorage, Alaska, since 1954 is 20 degrees Fahrenheit below zero. The coldest it has been on New Year’s Eve in that same time period is even colder: -25. But this year, the lows are expected to be 33 and 27 degrees respectively — meaning that 2014 will be the first year on record that the temperature didn’t drop below zero.

As Alaska Dispatch News notes, the last time the temperature was below zero (again: in Fahrenheit) was Dec. 26, 2013. That was the tail end of a cold snap, of the kind not uncommon in winter — particularly in Alaska. But ever since, temperatures have been above zero according to readings taken at the airport, with low temperatures reaching zero only once, on February 11.

All-years

Complete annual records from the National Oceanic and Atmospheric Administration begin on Jan. 1, 1954. Since then, the number of days Anchorage went below zero each year has dropped from an average of 33.2 in the 1960s to 16 in the 2000s. The year with the second-fewest below-zero days was 2002 (the red line on the graph above).
