Earlier this week, bitterly cold temperatures broke records in six locations across Saskatchewan, including Regina, where the mercury dropped to –27.7.

Next week, snow could be melting in the city.

Temperatures hit frigid lows while wave after wave of cold arctic high pressure was pushed over Saskatchewan by the jet stream.

Because the polar vortex pushed south over Manitoba and Northern Ontario, the jet stream was able to direct colder air masses over the Prairies.

Now, the jet stream has started to normalize, allowing low pressure from Alberta to move over the province, bringing milder weather as well as snow. 

Although things may cool slightly over the weekend, temperatures next week should return to, or even climb above, the freezing mark, as that jet stream pushes warmer air masses across the Prairies.
