From the Fairbanks News-Miner
A cold air mass that settled over the Tanana Valley late last week from the Yukon Territory resulted in bitter cold temperatures throughout much of the central Interior. The temperature dropped to 40 degrees below zero on Friday and stayed there for most of the next four days, though it did climb up to 38 below on Saturday at one point.
The coldest temperature recorded in the Interior was 57 below at Dry Creek, on the Alaska Highway between Delta Junction and Tok, and sub-50 below temperatures were reported from several other Interior communities. A low of 55 below was recorded at Circle Hot Springs and Manley Hot Springs. It was 52 below in Central, Eagle, Nenana and Tok.
The lowest temperature recorded at the Fairbanks International Airport, the official recording site for the weather service, was 46 below on Sunday, but a low of 52 below was recorded in North Pole. Two Rivers reported 51 below.
