UPDATE 4:15 AM Friday 29 December 2017: Extreme wind chills are occurring through the northern Grainbelt early this morning and will spread throughout most of southern Saskatchewan as a frigid arctic air-mass establishes prevalence over the province.

Cloud and some light snow have kept relatively moderate temperatures through Thursday night over the portions of Saskatchewan south of the Yellowhead.

The next blast of frigid arctic air is expected Friday and wind chills will be particularly severe.

  • Dress warmly. Dress in layers that you can remove if you get too warm. The outer layer should be wind resistant.
  • Cover up. Frostbite can develop within minutes on exposed skin, especially with wind chill.
  • Keep emergency supplies in your vehicle such as extra blankets and jumper cables.
  • If it’s too cold for you to stay outside, it’s too cold for your pet to stay outside.
  • Outdoor workers should take regularly scheduled breaks to warm up.

Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
