An extreme cold warning has been issued for Moose Jaw and the surrounding area by Environment and Climate Change Canada. 

Extreme wind chill values in the -40 to –45-degree range will come in Wednesday night and into Thursday as a bitterly cold Arctic airmass lingers over the region. 
Temperatures are expected to return to near-seasonal values by the weekend. 
A reminder to take precautions during extremely cold temperatures. Risks are greater for young children, older adults, people with chronic illnesses, people working or exercising outdoors, and those without proper shelter. 
Watch for cold-related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes. 
Frostbite can develop within minutes on exposed skin, especially with wind chill. 
Extreme cold warnings are issued when very cold temperatures or wind chill create an elevated risk to health such as frostbite and hypothermia.
