Only in the last article, we were informed about anomalous temperatures up to -33,3°C in the Jura region, Switzerland, around 1200 MASL /https://mkweather.com/amburnex-combe-switzerland-333c-the-strongest-frosts-of-winter-2021-2022-in-continental-europe-so-far// and the coldest times in France since 2012 /https://mkweather.com/avignon-france-with-the-coldest-period-since-the-legendary-winter-2011-2012//.
In a series of 7 Mkweather articles, before articles from the world, we will look at extremely cold morning, 22. December 2021 in parts of Europe and many regional temperature records or very low measured minimum temperatures.
Severe frosts up to -33,3°C were reported in the Alps (link above), regions in France reported the coldest winter period since a legendary winter 2012 (link above), Czechia was close to -25°C (this article), Slovakia below -22°C, Serbia, Germany, and Austria attacked -20°C in densely populated regions, cold was in Eastern Europe and Baltic region and below -10°C was measured in the UK and almost in Benelux, too /detailed information in the next Mkweather articles/.
Now, we will shift into Czechia, where mornings 21. and 22. December 2021 brought into frost valleys very low temperatures around -23/-24°C and in the next 2 morning, 23. December, below -25°C is in these regions possible.
On 21. December 2021, the coldest was in Rokytská Slať, southern Czechia, -23,0°C, Březník reported -22,0°C, or Kvilda-Perla -20,5°C /http://obec.sumava.eu/index.php/sumava/129-pocasi/18801-na-sumave-klesla-teplota-poprve-pod-20-c/.
Morning 22. December 2022 was even colder, with a minimum temperature in Rokytská Slať approximately -24°C (graph below) /note: the coldest stations in Czechia you will find here: https://www.ifrog.cz/teploty.php?sort=tu#temp)
From bigger cities / densely populated areas, Pec pod Snežkou reported -11,7°C or Karlovy Vary -10,6°C.
In Prague, -6,4°C was measured.
In Pec pod Snežkou, 22 cm snow cover is reported.
Severe frosts hit on 22. December already Slovakia, too, with a minimum temperature of -22,2°C in Samelova Luka, region of Gemer (near Dobšinská Ľadová Jaskyňa) /the next Mkweather article/.
Frosts below -20°C were measured practically in a large region of continental Europe from France, Germany, Switzerland, Austria, Italy, Czechia, Slovakia, or Serbia.
In Ukraine, Belarus, Baltic countries, and Poland, only little was missing to reach -20°C on 22. December (will be mentioned in the next articles).
While the first 2 decades of December 2021 were in European mid-latitudes relatively milder /https://mkweather.com/esrl-composites-for-europe-for-the-first-4-pentads-of-december-2021-early-winter//, already around Christmas and New Year 2021-2022 is 40% chance, that AO index will fall extremely low, into the interval -5/-7 /https://mkweather.com/12-30-runs-of-gefs-expect-an-extremely-low-ao-index-from-5-to-7-for-christmas-time-and-new-year//.
This destabilization of polar vortex should be associated with extreme blizzards across Europe /https://mkweather.com/gfs-expects-extreme-blizzards-in-europe-regionally-20-70-cm-locally-up-to-1-meter-of-snow-possible// and according to the newest outputs, parts of the eastern half of the continent should until New Year receive 30-70, regionally up to 1 meter of snowfall.
Just for these areas, a current GFS returned abnormally cold weather around 5. January 2022 /https://mkweather.com/frost-inferno-for-poland-ukraine-romania-its-abnormal-30c-40c// /agrees with our long-term outlook /https://mkweather.com/the-long-term-forecast-for-europe-until-30-january-2022/; https://mkweather.com/the-long-term-snow-forecast-for-europe-until-30-january-2022//.
Extremely cold air is shifting eastward and already on 23. – 24. December 2021, frosts below -25°C will be possible e.g. in Czechian frost valleys and in interval -20/-25°C in Germany, Austria, Slovakia, Poland, Baltic region, Ukraine, Romania, or other countries in northern Balkan.
An Arctic Ice Sea Extent was in the last period the 2nd highest in the last 15 years /https://mkweather.com/arctic-sea-ice-extent-is-the-2nd-highest-in-15-years//, moreover, La Nina is ongoing and strong AO- and NAO- are expected, together with wet MJO above SE Asia and negative IOD (additional factors).
An absolute peak of Winter 2021/2022 however, is forecasted between 31. December 2021 – 9. January 2022, so far /https://mkweather.com/the-long-term-forecast-for-europe-until-30-january-2022/; https://mkweather.com/the-long-term-snow-forecast-for-europe-until-30-january-2022//.
Classic warnings before a worsening of health problems such as hypothermia, virological situation, heart attacks, such as power outages, uprooted trees ar problems in travel are expected.
Therefore stay safe and warm.
