Just when you thought you could venture out with one less layer of clothing, Mother Nature turns down the thermostat.
Calgary is again under an extreme cold warning from Environment Canada.
The city was under an extreme cold warning for much of last week, until it was lifted on Friday morning as temperatures eased slightly.
It is forecast to get as warm as -18 C on Saturday, but winds will make it feel more like -32 C.
There is a risk of frostbite, so cover up if you head outdoors.
The winds will make it feel closer to -41 C tonight as temperatures dip, and Environment Canada is warning that anyone can get frostbite within minutes in those conditions.
Environment Canada now says the cold snap should end on Monday. Temperatures are projected to be above zero later in the week.
