The cold has avoided the month of December, at least in southern Quebec. It will arrive in the province next week, but in a fairly polite way. Forecast.

The polar vortex is wandering

The polar vortex decided to move this week. He took a little dip in the South, which in this case is represented by the Prairies and the Rockies. In Manitoba, Saskatchewan and Alberta, even in parts of British Columbia, the effect has been striking. Temperatures of -30° to -45° are recorded. You read correctly, it is about the temperature on the thermometer, and not about the feeling of the wind chill. In Red Deer for example, we are talking about a feeling of -55 overnight from Friday to Saturday.

Football at -20°

The vortex eventually makes its way to Quebec, but like many Quebecers, he has a slight penchant for the south. We’re not talking about Mexico here, but the Midwestern United States. In Kansas City, Missouri, for example, the NFL playoff game could be played at -21°, while the average temperature in that city in mid-January is around 5°. There is a risk of consuming more hot chocolate than beer in the stands.

A polite cold

The cold will not completely ignore us. It will settle in southern Quebec quite a bit all week from January 14 to 20, but it will not have the same bite as in the west. Maximum temperatures should remain around, even above the -10° mark, slightly below the average for the season. To the southwest of the Great Lakes, around Chicago, the temperature anomaly will be between 8° and 12° below normal.

The heart of winter

Many will say that this is completely normal, because we are entering the heart of winter, and they are right. Even though this cold is a little late this year. Normally, we see this kind of sequence around January 6. This coldest period of the season usually lasts until February 14.
