Only in the last article, we informed about the coldest December day in Vancouver in 52 years (-15,3°C: https://mkweather.com/vancouver-canada-hit-the-coldest-temperatures-in-52-years-153c/) and now we will shift behind the US-Canadian border, to Seattle.
In the city, only a minimum temperature of 17°F / -8,3°C was measured on 27. December 2021, which is the lowest temperature in the city since the legendary year 2010.

The city even reported 8 cm snowfall from 27. December 2021 (on 30.12. only 4 cm).
Anomalous coldwave hit many parts of northern and western USA – in Montana according to the newest information, only -38°F / -38,9°C was on 29. December 2021 measured /the next Mkweather article/.
Meanwhile, in Sierra Snow Lab, California, 455 cm of snowfall (193,7 inches / 16+ feet) fell such as the record amount for the station /the next Mkweather article/.

Conditions for tornado outbreaks and extremely cold Western, Central Canada, and N/NW USA are forecasted during January and February 2022, too, with possible Kentucky-like events across Midwest and Southeast, the USA /https://mkweather.com/kentucky-like-tornadoes-for-the-usa-in-january-and-february-2022-cfs-sees-extreme-temperature-differences-across-the-continent-and-sharp-frontal-boundaries-for-midwest-southeast//.
The next weeks therefore should bring even colder conditions in the region of Vancouver, Seattle, Portland, Edmonton, Alberta, or Helena.
