Long-termly expected extreme Arctic blast in Scandinavia is peaking and on Sunday, 24. October 2021, record low temperatures were measured /https://mkweather.com/winter-came-to-scandinavia-very-early-48-cm-snowfall-in-finland-and-27c-forecasted-for-sweden/; https://mkweather.com/extreme-frosts-in-norway-sweden-and-finland-are-confirming-30c-minimum-and-15c-maximum-temperatures-are-possible//.
9 meteorological stations in Sweden and Finland reported in the morning minimum temperatures only -20-/-25°C, with the coldest report from Nattavaara, where -24,6°C was measured.
This temperature is the lowest minimum temperature in Scandinavia in October since the year 2006 (in the last 15 years).
In Latnivaara, Sweden, -23,5°C, in Nikkaluokta, Sweden, -23,0°C, in Pajala, Sweden, -22,2°C, in Ranjson, Sweden, -21,5°C, in Salla, Finland, -21,3°C, in Sodankyla Vuotso, Finland, -21,2°C, in Parkalompolo, Sweden, -21,1°C, and in Ylinenjarvi, Sweden, -20,4°C was measured.
Moreover, northern parts of Scandinavia report anomalous up to 50 cm of snow – so high snow cover hasn´t been measured here in October decades, too.
Extreme early cold blast in Scandinavia is linked with a persisting October 2021 NAO- phase, but too with anomalously cold Arctic (only 3 years in the last 15 years had higher Arctic Sea Ice Extent: https://mkweather.com/arctic-sea-ice-extent-26-greater-than-last-year-12th-lowest-on-record-and-the-largest-since-2014/) and the last extreme coldwave in Greenland /https://mkweather.com/extreme-frosts-in-greenland-the-temperature-dropped-to-508c-october-record-for-summit-station-3216-masl-is-only-514c//.
Until 10. November, so extreme minimum temperatures aren´t forecasted for Scandinavia, so far and Indian summer in many parts of Europe is predicted – above central parts with possibly abnormal temperatures up to +25°C /https://mkweather.com/november-brings-an-abnormal-heatwave-france-30c-germany-25c-the-uk-23c//.
However, anomalously cold winter conditions should return already around late November and in December and early January 2021-2022, when according to many sources, the extreme Arctic and Siberian blasts in Europe are possible /https://mkweather.com/winter-2021-2022-forecast-for-europe-early-extreme-arctic-and-siberian-blasts-and-blizzards-late-dry-and-very-warm-conditions/; https://mkweather.com/winter-2021-2022-forecast-extreme-frosts-in-eurasia-in-december-in-north-america-in-february-early-canadian-stratospheric-warming-ne-pacific-blob-la-nina-qbo-and-shift-from-nao-to-nao-such-le/; https://mkweather.com/winter-2021-2022-forecast-a-peak-near-nao-already-in-december-ne-pacific-warm-blob-nao-and-early-spring-in-february-north-america-oppositely-warm-start-cold-end-of-winter//.
