An intense cold snap is expected to last all weekend across Quebec.

Quebecers should bundle up for a frigid Saturday night into Sunday. In some regions it will feel — and sometimes even dip — below -40 C.

The overnight high will be -19 C in Montreal and Quebec City.

Montreal, Laval, Châteauguay and Longueuil could drop from -36 C to as low as -48 C with the wind chill.

Environment Canada has issued an extreme cold warning for the entire province. If you are going out tonight, it is important to wear appropriate clothing and to layer to prevent frostbite and hypothermia.

The cold is expected to let up by Monday, with a snowstorm expected for Tuesday. Quebec could receive anywhere between 20 to 30 centimetres of snow.
