With the imminent arrival of single digit temperatures (and below) in Interior Alaska, I put together a map of the average and latest dates of the first sub-10 degree readings around Fairbanks. Most stations are within a week or so of the latest first sub-10 degree occurrence. Only those stations with at least 15-years of winter temperatures with no more than 10 missing observations per winter were included. Most stations are a solid 2-3 weeks late for this measurement.
Note: Today is the 32nd consecutive day with an above normal daily temperature in Fairbanks. You have to go back to the winter of 200202003 to find a longer stretch (62 days). Before that, 1997 had two streatch longer than 32 days.
