The first serious winter frosts in North-American Arctic!
Yukon, Canada, and Alaska, the USA reported in the last days really severe frosts, only a few degrees from all-time November records.
Only in October and early November 2021, the region was hit by extremely high temperatures and anomaly so-called “Early Canadian Stratospheric Warming”.
This anomaly is a predictor of strong NAO- and AO- phases and legendary cold Decembers in Europe and coldwaves in the wider European region thanks to upcoming NAO- and AO- are really forecasted /https://mkweather.com/nao-index-falls-to-2-0-the-lowest-value-since-legendary-35c-frosts-in-europe-in-january-february-2021-or-206c-in-april-2021/; https://mkweather.com/extremely-cold-weather-until-a-new-year-2022-arctic-air-should-come-in-3-peaks-around-30-11-14-12-and-christmas-wider-european-region-estimates//.
Meanwhile, the Arctic has become in the last days the coldest in this season in the last 15 years and 21 ships were ice-locked in anomalously cold Arctic /the next Mkweather articles/.
Very cold Arctic has brought in Canadian and Alaskan Arctic extremely cold conditions – in Beaver Creek, Yukon, Canada, only -42,7°C and in Northway, Alaska, only -42,2°C was measured.
Its values are only around 4°C below the all-time monthly November averages and we should consider them for extremely cold measurements.
Meanwhile, in the southern USA are persisting unseasonable heatwaves /https://mkweather.com/from-blizzards-arctic-blasts-floods-and-tornadoes-to-heatwaves-and-wildfires-weather-in-the-usa-and-canada-in-late-november-2021/; https://mkweather.com/colorado-is-suffering-a-lack-of-autumn-snow-212-days-without-snow-cover-means-5th-place-in-historical-tables// and in British Columbia and southern Alaska, the atmospheric river is bringing 500-years floods /https://mkweather.com/the-catastrophic-year-2021-for-pacific-coast-canada-nw-usa-after-496c-in-june-500-year-floods-in-november-2021//.
Anomalously cold air is forecasted to flood Central Canada and later even the northern USA and Great Lakes, the USA, until Thanksgiving, even – cold air from the region, therefore, hit soon densely populated southern regions, too.
In the Great Lakes region and parts of southern Canada, blizzard conditions are(again) possible.
