Temperatures across Alaska's Interior plunged deep into negative digits Sunday night, with Fairbanks hitting 41 degrees below zero and nearby Eielson Air Force base seeing the mercury drop to 45 below, according to a special weather statement from the National Weather Service.
Temperatures at weather stations in the Interior ranged from minus 38 at Delta Junction and Fort Wainwright to minus 51 at Huslia and Bettles, the two coldest stations listed by the weather service.
The weather service said temperatures would remain low through Wednesdays before warming to normal by later in the week.
In Anchorage overnight, temperatures of -4 to -6 degrees were seen over a widespread area, said Matthew Clay, meteorologist for the National Weather Service Anchorage office. The sub-zero temperatures are the first official ones in Anchorage for 394 days, the second-longest such streak.
The coldest temperatures recorded in the Anchorage bowl were at Campbell Creek Science Center in East Anchorage, which saw -18 degrees around midnight. Eagle River Valley saw the coldest teperatures in the Municipality of Anchorage at -21 degrees.
Clay said that chances of more snow for Anchorage was slim in coming days.
Meanwhile, several weather stations in Southeast Alaska reported record warm temperatures, according to a separate NWS statement.
Skagway, Haines, Juneau, Petersburg and Ketchikan -- which saw temperatures ranging from 44 (Haines and Juneau) to 49 (Ketchikan and Petersburg) on Sunday -- either tied or exceeded previous records for that date. In Skagway, where temperatures dipped only to 38, and Petersburg and Klawock, which got no colder than 41 Sunday, new daily high minimum records were also set.
Juneau also set a new rainfall record for January with 11.29 inches, beating the previous record, set last year, of 10.16 inches.
