Bitter cold -65°F temperatures hit Alaska

By: Dr. Jeff Masters, 5:13 PM GMT on January 30, 2012

If you're wondering who's getting all the cold air the lower 48 states is missing during this non-winter of 2012, the answer during the past week has been Alaska. Our 49th state is used to intense winter cold, but not like what they've experienced during the past week. Friday night and Saturday night, temperatures plummeted to -50°F and -51°F in Fairbanks, marking the first time since 1999 the city had seen back-to-back minus fifty nights. The low temperature so far today at the Fairbanks International Airport has been -44°F, giving the city sixteen days of -40°F temperatures so far this month. Since 1906, there have only been three years (1906, 1934, and 1971) with more 40 below days during the month of January. At forty below zero, the air is so cold that the water vapor condenses out into ice crystals, which float in the air creating a low-visibility fog. A large area of Alaska experienced bitter cold temperatures of -50 to -65°F Sunday morning:

The cold snap is expected to continue through mid-week, with more -65°F temperatures possible in the interior valleys north of Fairbanks. Warmer air is expected to arrive state-wide by Thursday.

All-time U.S. low temperature record threatened?
The coldest temperature ever recorded in the U.S. was a -80°F (-62.2°C) reading from Prospect Creek, AK (about 180 miles north of Fairbanks) on January 23, 1971. A weather station just a few miles from Prospect Creek, the Jim River DOT site, appears to have recorded a low temperature between -78°F and -79°F Saturday morning (January 28, 2012), shortly before the weather station lost power. Keeping the power going at -70 is very tough, and it is not a surprise to see that the station lost power during this extraordinary cold snap. Power just returned this morning to the site, where the temperature was -66°F at 7 am AKST. Wunderground's weather historian Christopher C. Burt is corresponding with Alaska's state climatologist to get more information on whether the data during the power outage will be recoverable, and how reliable these near-record low temperatures might be.

This capture was shot just outside of North Pole , Alaska. It was a very cold and slow night for aurora hunting. One of these days I will learn to leave earlier in the evening.
