After a mild spell at the end of the year, southern Quebec can expect to receive a wave of cold air straight from the Arctic. Good coats will be essential: low temperatures could reach -20°C at their peak.

A wave of cold air coming from the western Canadian Arctic is heading towards southern and central Quebec, according to Environment Canada. The coldest days will be Sunday and Monday in the Montreal region, with a maximum of -10°C and a minimum of -20°C.
Predictions well below normal temperatures for this period. In Montreal, you can usually expect a maximum of -5°C and a minimum of -14°C in early January.
A few additional snowflakes could fall on southern Quebec on Thursday and Friday. “But we can’t expect any major storms for the next week,” says Gina Ressler, meteorologist at Environment Canada.
-This extreme cold is the result of a blocking regime: a meteorological configuration where a reversal of air flow sends cold winds to the south and warm winds to the north.
Northern Quebec will therefore experience “much warmer than usual” days, according to the meteorologist. In the Kuujjuaq region, the mercury will be between zero and -5°C as of Friday, at a time when the average temperature is around -20°C.
In Montreal, no mild spells are in sight at the moment, because this weather pattern will not change for at least a week.
