Environment Canada is calling for a bitterly cold night in southern Manitoba. 

In fact, an Extreme Cold Warning has been issued for the entire southern half of the province with the coldest wind chill values expected to be between -40 and -45. In Steinbach, the mercury is forecast to drop to -33 degrees with a wind chill of -43 overnight.

According to Environment Canada, a high-pressure system is moving into the southern prairies, causing a clear sky and ushering in cold arctic air. Conditions will improve Wednesday afternoon as relatively warmer air begins to move into the southern prairies.

Environment Canada is asking everyone to watch for cold-related symptoms including 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. Everyone is encouraged to cover up and if it is too cold for you to stay outside, it is too cold for your pet to stay outside.
