If you're checking out the CP Holiday Train in Swift Current this evening or heading outside for any other reason at all today, you will need to bundle up.

An extreme cold warning has been issued by Environment Canada for parts of southwest Saskatchewan including the Swift Current, Herbert, Cabri, Kyle, Lucky Lake, Gull Lake and Leader areas with very cold wind chill factors between minus 40 and minus 45 expected. While extreme wind chills are to moderate this morning and afternoon, they are expected to return this evening.

In these conditions, frostbite could occur on exposed skin within minutes. The weather agency is reminding people to watch for symptoms of cold-related illnesses like shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes, and to cover up whenever they go outside. They also remind everyone that if it's too cold for you to stay outside, it's too cold for your pet to stay outside.

The cold snap will be brief, however, as temperatures are expected to warm up considerably starting tomorrow.
