Extreme warmth will develop across the Arctic region this weekend, in response to a very strong upper ridge and high pressure system. Northern Atlantic, Iceland, Greenland, Faroe Islands, Scandinavia and Scotland will experience unusually warm weather for this time, with daytime temperatures 10-15 °C above normal. The pattern evolving across Europe displays an extremely strong upper ridge centered over the Arctic region with several deep cyclones located to its west over the northern Atlantic. Together with powerful high pressure system across the northern Europe, this results in a sharp pressure / temperature gradient right across Iceland. A very strong southern jet stream will advect additional warm airmass towards already very warm weather caused by significant subsidence beneath the upper ridge. … Continue reading Extreme warmth for Iceland and Greenland this weekend, Nov 16-18th
