Historic winter in the USA: -51°F / -46,1°C in Bottineau, North Dakota, 128 year record broken




As we informed during last days, the USA and Canada face to extreme Arctic blast, which is bringing coast-to-coast snowstorm affecting 192 million people and regional all-time temperature records /https://mkweather.com/2021/02/13/the-usa-record-temperatures-50f-47c-coast-to-coast-snowstorm-affect-190-millions-of-people//.

After -50°F / -45.6°C in Minnesota /https://mkweather.com/2021/02/14/ely-minnesota-the-usa-50f-456c-records-in-midwest-and-texas-expected//, even stronger frosts surprised on Valentine, 14. February 2021 North Dakota, where -51°C / -46.1°C was observed in Bottineau, what is the coldest temperature in the city in history, overcoming a 128-year record from 19. century!

In many parts of the USA continues coast-to-coast snowstorm, with enormous amount of warnings and advisories /we have noticed this pattern already before more days: https://mkweather.com/2021/02/10/2-massive-snowstorms-hit-the-usa-2021//.

Extreme blizzard hits southern Texas and Louisiana, too, where are valid warnings before a blizzard conditions including Gulf Coast.

In the mountains, high risk of avalanches is still forecasted /https://mkweather.com/2021/02/10/deadliest-week-for-avalanches-in-the-us-in-more-than-100-years-2021//.

Wave of the most widespread cold weather in 21. century hit Canada, too /https://mkweather.com/2021/02/13/canada-set-to-the-most-widespread-cold-of-the-century/; https://mkweather.com/2021/02/10/edmonton-canada-438c-only-01c-from-all-time-record-from-1994//.

In Texas, all-time temperature record or many regional all-time temperature records are possible. Regional all-time records are too expected in parts of Midwest – mainly southern states.

Similarly such as in Europe, important factors for declining of temperatures are mainly extremely low relative humidity and high snow cover /https://mkweather.com/2021/02/13/a-big-siberian-winter-forecast-for-europe-which-country-will-have-excellent-conditions-relative-humidity-and-when-2021-mk/https://mkweather.com/2021/02/11/1048-hpa-pressure-high-above-central-europe-at-the-weekend-then-extremely-dry-siberian-air-and/https://mkweather.com/2021/02/11/updated-estimates-of-expected-national-minimum-temperatures-ine-europe-during-ongoing-siberian-wave-2021-mk// and important circulation factors are mainly peaking La nina /https://mkweather.com/2021/02/05/the-coldest-earth-for-7-years-strong-impact-of-la-nina-is-here// and extreme strong negative phase of Arctic Oscillation /https://mkweather.com/2021/02/06/ao-index-7-this-looks-like-historic-cicrulation-conditions-next-week//.

Energy prices have increased during last days, extreme winter is associated with many traffic accidents, health problems /e.g. https://mkweather.com/2021/01/16/heart-attack-influenza-cancer-frostbites-hypothermia-covid-what-you-should-to-know-about-arctic-and-siberian-coldwaves// and many dead animals, too.
