Keep an eye on this graph over the next few days or so (zacklabe.com/arctic-tempe...). An extreme #Arctic winter warming event is occurring bringing a narrow band of near freezing air temperatures close to the North Pole (associated with poleward movement of excessive heat and moisture).

The extent of #Arctic sea ice is already a record low for this time of year, and yet a highly anomalous surge of heat and moisture is still inbound toward the North Pole over the week ahead... Local temperature anomalies will exceed 20°C above average. Graphic from www.karstenhaustein.com/climate 🧪

These types of Arctic "heatwaves" are most common during the months of December through February, which is when temporary spikes of unusual warmth can reach the northernmost latitudes. They typically don't last very long though. You may be interested in this work: science.nasa.gov/earth/climat...
