Expected wind chills as low as 50 prompt extreme weather warnings for all of Sask.

All of Saskatchewan is now under extreme cold warnings as wind chill values are expected to drop to 40 to 50at times on Friday and through the weekend.

Most of Saskatchewan was under extreme cold weather warnings on Thursday morning. Environment and Climate Change Canada (ECCC) issued alerts for the rest of the province, including Regina and Yorkton, late on Thursday afternoon.

ECCC issues extreme cold weather warnings when temperatures or windchill create an elevated risk for frostbite or hypothermia.

Natalie Hasell, an emergency preparedness meteorologist for the national weather agency, said these extremely cold temperatures are expected to stick around until at least Tuesday.

"We'll have to wait and see if this forecast works out, but it does look like things should improve come Tuesday or Wednesday, at least for the southern and central parts of the province," Hasell told CBC news on Thursday.

Hasell said the extremely cold wind chills are a result of an Arctic air mass sweeping through the province. She added this is the coldest weather many parts of the province have seen this winter season.

The emergency preparedness meteorologist said it's important that everyone take precautions with the cold weather even if you consider yourself healthy.

She recommends trying to limit your exposure to these cold temperatures but said if you decided to brave the freezing weather, you should be prepared because skin can freeze within minutes in the current conditions

"We want people to dress warmly, dress in layers. Outer layers should be wind resistant,footwear should be waterproof and insulated," Hasell said

"Cover as much exposed skin as possible. Try to stay dry so that you don't lose as much body heat as quickly."

Hasell added it's important to have the winter necessities if you are driving in this cold weather such as jumper cables, warm clothes and a charged phone
