Extreme warmth across Iceland verified this weekend – eastern parts peaked up to around 18 °C, Nov 17-18th

The pattern during the past days has been an exceptional across the northern Europe and Arctic region. A very powerful upper ridge developed and brought an extreme warmth very far north across the northern Atlantic, Iceland and also Greenland. Northern Iceland has seen the most extreme warmth as a pronounced Foehn effect has pushes afternoon temperature into 17-18 °C range both on Saturday and Sunday, Nov 17th & 18th.

The pattern was dominated by a very powerful upper ridge and high pressure system across the northern Europe, while a deep trough / cyclone was located over the northern Atlantic and resulting in strong warm airmass advection towards the Arctic region. Strong south-southeasterly low-level winds across Iceland usually result in downslope flow across the northern half of the island where a significant Foehn effect winds develop in the narrow fjords. Together with severe winds, airmass warms up into the range well above normal.
