An especially chilly Sunday is forecasted for several regions across Saskatchewan – as extreme cold warnings come into effect.

The early morning hours of Sunday saw Environment and Climate Change Canada (ECCC) issue warnings for the cities of Saskatoon, Prince Albert and their surrounding areas.

Temperatures in both cities are expected to reach minus 30 C - which will combine with light northerly winds to produce periods of wind chill exceeding minus 40 C.

The dangerous winds are expected to die down late Sunday morning.

In addition to the warnings in central Saskatchewan, a large swath of the province’s north – which includes Uranium City and Stoney Rapids – are expected to reach minus 45 C with wind chill values.

Conditions “will moderate” during daylight hours but ECCC warns that temperatures are expected to drop again overnight.

Extreme cold warnings in southern and central Saskatchewan are issued when the temperature or wind chill is expected to reach minus 40 degrees for at least two hours.

The criteria is upped to minus 45 degrees for warnings that affect northern Saskatchewan.
