Scandinavia is preparing for life-threatening Arctic blasts, temperatures up to -35°C and blizzards in the Baltic region are forecasted!




In the last series of articles (our homepage), since late October 2021, we have been warning before an early arrival of winter conditions in Europe, which were forecasted to strengthen until the end of the month.

NAO index is forecasted to fall into values around -1 already in 10 days /https://mkweather.com/the-end-of-november-should-bring-a-very-low-nao-index-greenlandic-arctic-and-siberian-winter-should-come-very-early-peaks-between-20-11-20-12-2021//, with a result of extremely cold conditions across wider European region /https://mkweather.com/winter-should-be-strengthening-until-new-year-2022-wider-european-region-estimates// until Christmas 2021, or maybe even a New Year 2022.

These forecasts were supported by ensemble outputs (GFS model) /https://mkweather.com/extended-gfs-ensemble-forecast-for-european-region-until-30-november-2021-arctic-winter-will-come-already-next-week//.

Near very low AO index, winter-like patterns are already appearing in the USA, Siberia, China, or North Africa /https://mkweather.com/severe-snowstorms-in-midwest-during-thanksgiving-25-11-are-possible/; https://mkweather.com/delyankir-418c-dzalinda-408c-oymyakon-405c-if-these-frosts-had-struck-a-week-earlier-they-would-have-been-historic/; https://mkweather.com/northeastern-china-hit-the-strongest-blizzard-in-116-years-in-taiwan-and-japan-still-summer/; https://mkweather.com/the-first-snow-in-algeria-morocco-and-tunisia//.

The newest forecasts for Scandinavia count with a possibility of values up to -25°C for basins and valleys around 29. November 2021, which should mean a very rare potential for temperatures up to interval -30/-35°C in Lapland and Scandinavian Mountains (lower situated basins and valleys below 1000 MASL).

These temperatures are deeply below November’s and early December´s historic averages.

Severe frosts below-20°C are according to the next extreme runs possible in eastern parts of Baltic states, Belarus, and Ukraine, which will be a topic of one of the next Mkweather articles in the series.

T850 hPa should a few days earlier reach below -20°C above parts of Scandinavia.

Moreover, snow cover and severe blizzards are forecasted for large parts of the Scandinavia and Baltic states – including Baltic states it should fall above 50 cm of snow, regionally.

Air, which will flood Europe soon, will have origin in Greenland, where record -55,6°C was on 7. November measured – so extremely low temperatures have never appeared above Summit so early, so far /https://mkweather.com/summit-camp-greenland-556c-possibly-never-has-been-so-extremely-cold-so-early-in-the-season//.
