Quebecers will have to take advantage of the relative mildness during the day on Thursday before an extreme cold spell arrives through Saturday that will affect virtually the entire province.
Environment Canada has issued an extreme cold warning that will send temperatures plummeting for at least 48 hours.
Temperatures of -26°C to -24°C are expected in the south and center of the province, particularly in Quebec and Montreal, while the mercury reading in Saguenay is -29°C.
The sun will be present during these two days of polar cold, which can lead to frostbite if your hands are less well covered.
The presence of strong winds will produce extreme wind chills that can reach -55C in the northern sectors of Quebec, according to federal forecasts.
Meanwhile, the weather is more unsettled with clouds and light snow showers in places, particularly in the Saint-Laurent River Valley and eastern Quebec.
The mercury will record comfortable temperatures of -2°C in Montreal and -5°C in Quebec before dropping quickly in the evening when strong winds bring blowing snow.
