Experts say that despite the warm and mild temperatures that extended throughout most of the fall season, winter fury may come soon, but freezing temperatures are not expected to persist.

According to a report from The Weather Network, Canadians should prepare for colder than usual temperatures across much of the country in December.

After a cold wave until the end of 2022, temperatures are expected to fluctuate.

Meteorologist Doug Gillham wrote in a Weather Network report about this matter, saying: "We expect that once we enter January and February, winter will take breaks with periods of mild weather, especially in southern Ontario to Newfoundland and Labrador," for the third consecutive year.

Adding that winter weather in Canada is expected to be mainly affected by the large-scale climate pattern known as La Niña - associated with cooler-than-usual sea surface temperatures in the central and eastern tropical Pacific Ocean.

But La Niña is not the only weather phenomenon expected to drive the bitter winter fury.

Added to the mix is a wave of the polar vortex, which the Weather Network expects will be present over northern Canada, causing significant levels of Arctic air to blow south during what is expected to be a cold December.

As we approach January and February, La Niña is expected to bring cold and active winter weather across western Canada, with mild and stormy conditions directed from the Great Lakes to Atlantic Canada.

However, the Weather Network indicates that winter weather in western Canada may sometimes shift eastward to an area stretching from the eastern prairies to Quebec, resulting in milder weather in British Columbia and Alberta.

As a result, the Weather Network says Canadians will face a "volatile winter" – a season "characterized by long periods of harsh winter weather, and long periods of mild weather that might make you wonder, 'What happened to winter?'"
