Clear skies overnight enhanced the impact of a low-riding jet that has been drawing frigid air south, and early Monday most of Alberta woke up under an extreme cold warning.
As of 7 a.m. Monday, air temperatures across the province were in the mid-minus 20s to mid-minus 30s, with windchill values as cold as -45.

Calgary and areas in southwestern Alberta were not under the extreme cold warning, however both the temperature and windchill values were cold.
Environment and Climate Change Canada explained, “Wind chill values will moderate by Monday afternoon, although extreme cold wind chills will return tonight for some areas.”

Since the start of February, temperatures in Calgary have ranged from -8 C to -28 C compared to seasonal values of -1 C to -14 C.
There will be a slight warmup in Calgary by the middle of this week, however the warmest temperatures for the next seven days will still be at least 10 degrees colder than average.
Some light and scattered snow is possible across the region in the middle of this week, however accumulations should be minimal.
