In southern Norway an probably too Czechia, the coldest temperatures since Beast from the East 2018 were measured /https://mkweather.com/2021/02/13/southern-norway-386c-20-days-with-28-40c-in-a-row/; https://mkweather.com/2021/02/14/jeleni-u-mostu-czechia-321c//.

Finally, in Hungary, all-time national temperature record was possible /https://mkweather.com/2021/02/13/hungary-355c-all-time-national-record-2021// (if recognized).
There are however 2 countries, where frosts wasn´t so extreme - Poland, with minimum temeprature "only" -26,1°C from the start of coldwave /https://mkweather.com/2021/02/07/rozanymstok-poland-already-261c-but-outputs-12c-warmer-than-expected-100-year-winter-2021//, Austria, with "only" -23,7°C on Sunday, 14. February 2021 (https://www.tt.com/artikel/30779207/minus-23-7-grad-in-st-jakob-die-eiszeit-geht-langsam-zu-ende) and -29,4°C in the mountains.
In Poland, only -19,6°C was on Sunday measured in southwestern border of the country and it´s a question, if -26,1°C from the start of coldwave will be overcame on Monday, Tuesday, Thursday and Friday - on Monday on the west, on Tuesday, Thursday and Friday on the east of the country.
Temperature still should surprise, in case, if extremely dry air will shift above Carpathian basins, but there is a possibility, that -29,7°C form Biebrzy, January 2021 will be the Polish winter TOP temperature /https://mkweather.com/2021/01/19/surprising-night-in-poland-biebrzy-297c// - the lowest temperature since 2010.
Poland was long time situated on the front side of anticyclone in very cold, but humid air, while western and southern parts of Central Europe reported in very dry sector on the back side of anticyclone extreme frosts.
During the next nights, extremely dry air will be quickly shifting above Poland to the east and there should be surprise, but too a disappointment from measured temperatures.
However, at all, Poland experiences thanks to La nina /https://mkweather.com/2021/02/05/the-coldest-earth-for-7-years-strong-impact-of-la-nina-is-here//, negative AO phase /https://mkweather.com/2021/02/06/ao-index-7-this-looks-like-historic-cicrulation-conditions-next-week// and very long Major SSW in the Winter 2020/2021 one of the codlest winter times in this millennium.
Thanks to cold-set circulation parameters, extreme frosts should return into continental Europe until the March 2021, therefore stay warm and stay watch weather with us /https://mkweather.com/2021/02/09/neverending-winter-siberian-blasts-until-late-march-2021//.
