A new weather forecast says parts of the country are in for some of the coldest temperatures of the season, and you'll probably want to break out your winter jacket. Canada's weather forecast says cold air from a polar vortex will descend into eastern regions next week, making for "frigid" temperatures and the possibility of lots of snow. According to The Weather Network , Eastern Canada is set to see temperatures that will feel much colder than most of November so far next week, and an "abundance of snow" is also possible for many in the region. According to the outlet, a "lobe" of the polar vortex, a wind pattern surrounding the Earth's poles that has the coldest air on the globe, will head into areas like the Great Lakes region, the Eastern Prairies and parts of Atlantic Canada. The coldest air will arrive on Monday and into Tuesday, with wind chills feeling close to C in northern Ontario, according to the forecast.

Visit our Complete Guide to Fall for an in-depth look at the Fall Forecast, tips to plan for it and much more! It's worth considering if the polar vortex is the reason behind this shift in weather patterns. Over the last week, there have been indications that the polar vortex is expanding over the North Pole. This expansion, combined with an amplified weather pattern, will guide a sliver of the polar vortex south. The residual warmth of the summer season is baked into the ground. The warm waters of the Great Lakes will also fight to moderate the air. A lack of snow cover works to warm the air as it travels great distances over Canada. The Prairies get a taste of some seasonably cool temperatures, with highs stubbornly hanging in the single digits for Saskatchewan and Manitoba by Friday. Weather balloons have been sampling the atmosphere for many decades, and on Oct. The Weather Network. More News from The Weather Network.

The reason we do this is because geopotential height aka air thickness is much higher in the stratosphere than in the troposphere. Thank you!

During the winter schedule the blog is updated once every week. Snow accumulation forecasts replace precipitation forecasts. Also, there is renewed emphasis on ice and snow boundary conditions and their influence on hemispheric weather. Snow accumulation forecasts will be replaced by precipitation forecasts.

In Figure i, I do show the anticipated surface temperature anomalies for the winter just below the AER winter forecast for comparison.

Eastern Canada has had a relatively easy winter so far, temperature-wise, but that's going to change in a hurry. The most potent lobe of the polar vortex will descend across Canada late this week, and its short-lived stay will pack a punch. It's been an incredibly mild stretch of weather across the country throughout January, but February will buck the trend in a big way. Early this week, the polar vortex is meandering across Hudson Bay, but some reinforcing shots of cold air will displace the polar vortex across Ontario, Quebec and Atlantic Canada. A clipper system moves through on Thursday along the dividing line of Arctic air. Behind the low, the cold air is free to surge south. We'll have to watch intense lake-effect bands off Georgian Bay and Lake Huron as the lakes remain ice-free. Here's the most likely scenario for temperatures early Saturday morning Feb. It's likely a few locations in northeastern Ontario and Quebec fall into the s into Saturday morning. A strong ridge quickly builds in behind, so temperatures moderate rapidly into Sunday, Feb.

Warm weather has dominated across Canada through most of the fall season. However, the past few weeks have featured an abrupt transition into a period of wintry weather for most Canadians. A strong start to the winter season is anticipated, with colder-than-normal temperatures across most of Canada during the month of December. In addition, a piece of the polar vortex is expected to be located over northern Canada, providing an abundant source for Arctic air that should frequently plunge south and spread across much of the country during December. We expect that once we get into January and February, however, winter will take a couple of breaks with periods of mild weather, especially from southern Ontario to Newfoundland and Labrador. However, we expect that at times the frigid weather will shift east, and stretch from the eastern Prairies to Quebec with milder weather across B. This is much like what we saw during January and February of last winter. When we look at the big picture for the season as a whole, we expect that temperatures will be near to below normal across most of Canada, but parts of Atlantic Canada and Nunavut will be warmer than normal. However, across southern parts of Atlantic Canada, southern Ontario, and even into 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 across much of the region, it is possible that southern areas will end up with below-normal snowfall.

Also, I had ice on my roof. In some areas, temperatures dropped to degrees below average. Thks again and take care. The lower stratosphere seems to have been perturbed from a combination of factors in the stratosphere but also the troposphere. Other times, these changes stop near the stratosphere-troposphere boundary called the tropopause. If that is why the area over Alaska and NE Siberia was colored white rather than blue in that diagram, then that's what I meant. The reason why I'm searching and reading your article is unexpected cold temperature events. Need an account? Below is a look at the temperature anomalies for December , with the various shades of orange, red and brown highlighting warmer-than-normal temperatures across all of Canada, and most of the U. Saturday, March 2, When this happens, it can split into multiple smaller vortices or be displaced from the pole.

Seasonal and observed and predicted North Atlantic sector only see insert daily polar cap height i. Below are also the snowfall anomalies since 1 November see Figure. During El Nino winters, visits from the polar vortex are most likely in mid-January and about four weeks later in early-to-mid-February. That will be watched closely. December has so far seen a slightly weaker and warmer than average polar vortex. The front is forecast to flip these temperatures much colder over the weekend and next week. And the weak Arctic boundary forcings compounded the challenge at least for me. Below is a look at the temperature anomalies for December , with the various shades of orange, red and brown highlighting warmer-than-normal temperatures across all of Canada, and most of the U. The first thing you might notice is that the winds change direction in the late summer and spring. Bare patches exist in much of the Northern Plains and Canadian Prairies. Comment policy Permalink. This week the polar vortex PV is predicted to be shifted south of the North Pole centered over the Barents-Kara Seas though mostly circular in shape Figure 13a. This cold will spread east on the next day, Nov 1st. Climatology of highest and lowest daily values is from Climate Forecast System Reanalysis.
