Nome airport is basking in warm midwinter sunshine this afternoon and reporting a temperature of 50 °F at 1 pm AKST, which is a new all-time high temperature record for January and for the period of December through March; historical temperature data in Nome go all the way back to 1907. There appears to be little chance that today's measurement is erroneous, as nearby Golovin is also reporting 50 °F.
If the temperature rises any higher, the November-March record will also be broken (50 °F on November 1, 1928). Nome has never before observed a temperature above 50 °F between October 17 and April 9.
[Update 4 pm AKST: The temperature has reached 51 °F, so it is unequivocally a new winter record.]
