Alaska experiences record-high temperature for December, freezing rain
Imagine running a 5K and winning the race by 10 minutes. Thats analogous to what is transpiring in Alaska at the moment. An exceptional slew of records has tumbled in the wake of extreme warmth, with highs up to 45 degrees above average.
The anomalous warmth has also brought record moisture, with top-tier rainfall totals thanks to the airs capacity to transport more humidity.
The ongoing spate of warmth is tied to a sprawling dome of stagnant high pressure banked southeast of the Aleutians in the northeastern Pacific. Reinforced by unusually warm ocean waters north of Hawaii, that high-pressure heat dome is inducing sinking air. That brings about additional warming.
Historic U.S. weather events in 2021, by the numbers
This latest bout of record-shattering warmth caps off a year that has brought a number of high-end climate extremes to North America, including a withering late June heat wave that heated Seattle up to 108 degrees.

Meanwhile in the Puget Sound region highs have been in the 20s. Looks like the two areas have swapped weather.
