It has been a cold few weeks for parts of the Northern Plains, Prairie Provinces and even parts of eastern Canada. This should continue tonight into tomorrow morning before a brief relief is in store. Below is a depiction of a brief relief from extreme cold temperatures for parts of southern Manitoba near the International border.
As you can see a brief relief is in store for parts of S Saskatchewan, North Dakota and S Manitoba, but it will be short lived as cold returns on Saturday. Below is the wind chill values expected for tonight into tomorrow morning.
3:29 PM CST Wednesday 30 January 2019 Extreme Cold Warning in effect for:
All of Manitoba
A bitterly cold Arctic air mass in combination with light northwesterly winds will give extreme cold conditions over southern Manitoba. Wind chill values of -40 to -50 will develop this evening and persist into Thursday morning. A moderation of temperatures will bring an end to the extreme wind chills Thursday afternoon although temperatures will remain below seasonable normals. Extreme wind chills are not expected to redevelop Thursday night. Information regarding how to prepare for episodes of extreme cold can be found at the Province of Manitoba health web site:
Extreme cold puts everyone at risk. Watch for cold related symptoms: shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes. 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. Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia.
