With the forecast indicating sunshine on the coldest days, and temperatures in the minus 20s and windchills much colder yet it is bringing an extreme cold warning to the area.

Meteorologist Terri Lang with Environment and Climate Change Canada shared the connection between clear skies and cold spells.

"It has to do with where the air is coming from, and of course it's Arctic air, so we know it's cold to start witch really deepens in the Arctic, where there's no sunshine," she said. "When it starts making its way down, it does modify somewhat as it comes along, but at night, when it's very clear, just because of the subsiding motion in the atmosphere, we get clear skies with high-pressure systems, ones that come from the Arctic."

During the day, the earth absorbs radiation from the sun.

"That's why we get warmer temperatures during the afternoon, but at night, the earth releases that into the atmosphere, and that allows us to cool, so if the skies are clear, it all goes off into space."

Lang said this is why even a little bit of cloud, when it's that cold, will make a difference.

"The cloud is like a little blanket that kind of keeps that heat closer to the earth," she noted.

"It does sound counterintuitive, but we know clear and cold is very winter-like and very Saskatchewan-like."

Lang said we could be feeling the cold well into next week.
