Tuesday, December 21st 2021, 4:46 am - The Weather Network is forecasting a come-and-go winter for much of the country, with periods of high-impact weather for the season ahead.
Devastating floods, record warmth, and even blizzards have all grabbed headlines across Canada during the fall of 2021. While we have seen a few quick shots of early winter weather, consistent cold has been missing so far across the country. Is this mild and stormy pattern a preview of what is to come this winter? For a look ahead at what we expect during December, January, and February, please read on.
A tumultuous temperature pattern is expected across Canada during the upcoming winter season. This will result in a come-and-go winter across the eastern half of the country, with periods of high impact winter weather, interrupted by periods of mild weather. Across western Canada, we expect that frigid temperatures will out-duel any periods of milder weather. Meanwhile, across eastern Canada, the periods of mild weather should be more dominant.
Here is a look at our national temperature forecast for the winter of 2021-2022.
For much of the winter season, we expect that the focus of the frigid weather will be across western Canada, with rather mild weather surging north into eastern Canada at times. However, we anticipate two different versions of that pattern.
At times, very mild temperatures will dominate across the eastern half of the country. This will result in extended thaws across southern parts of the region, and seemingly ‘wipe away’ winter.
However, at times, the frigid weather across western and central Canada will attempt to spread south and east. This would set up a battleground between the Arctic air to the north and the very mild air to the south, that will extend from southern Ontario to the Maritimes. This scenario will produce periods of high-impact winter weather with messy systems tracking across the region.
While it looks like the milder version of the pattern will be more dominant, we are still uncertain about the exact balance between the two scenarios – which will be the key to how the winter is remembered from the Great Lakes to the Maritimes.
Meanwhile, a La Niña weather pattern in the Pacific Ocean will continue to support an active storm track across southern Canada, leading to above normal precipitation and snowfall for southern parts of B.C., Alberta, Ontario and Quebec. However, across southern Ontario and into parts of southern Quebec, several of our winter storms will bring a messy mix of snow, ice, and even rain. So, while we still expect an abundance of snow (despite the milder temperatures), southernmost areas could end up with below normal snowfall.
Below you can find a more detailed look at your provincial forecast, as well as a sneak peek into early spring.
A stormy pattern is expected to continue across southern B.C. through the winter season, resulting in above normal precipitation totals. This will bring an abundance of snow to the alpine regions, and at times, we expect significant snowfall across lower elevations, including Vancouver and the Lower Mainland, Victoria, and the Okanagan Valley.
In addition, colder than normal temperatures are expected to dominate the season, and potentially linger well into March. This should set the stage for an extended ski season.
WATCH BELOW: HOW LA NIÑA WILL IMPACT WINTER WEATHER ACROSS B.C.
A frigid winter is expected across the province. While a few periods of milder weather are expected, we have a heightened risk for extended periods of severe cold, as well as for blizzard conditions as Arctic air plunges south across the region. A snowy winter is expected across the southern half of the province, including Calgary. Near normal snowfall is expected elsewhere, including Edmonton.
MANITOBA AND SASKATCHEWAN
A classic Canadian winter is expected across the region. While a few periods of milder weather are likely, we have a heightened risk for extended periods of severe cold and also for blizzard conditions at times as Arctic air plunges south across the region. A snowy winter is expected across southwestern parts of Saskatchewan, but otherwise, the rest of the region should see near normal snowfall, including Saskatoon, Regina, and Winnipeg.
