A heat flux is forecast to enter the Arctic early February 2025 that could raise temperatures to levels more than 30°C higher than 1979-2000, as illustrated by the above forecast for February 2, 2025 12Z, run January 25, 2025 06Z by Climate Reanalyzer.
The situation has been described in earlier posts, most recently in this post, which adds that as temperatures rise, a lot of heat is accumulating in the North Atlantic and at its surface. Much of that heat can be pushed abruptly into the Arctic by strong longitudinal wind, accompanied by sudden acceleration of the Gulf Stream and its extension northward. Accordingly, this can cause a huge temperature peak in the Arctic.
