Weekend Outlook: Return of the Polar Vortex

Nighttime lows will approach -30°C and daytime highs will struggle to climb above -20°C

Cold air lobes associated with the polar vortex revolving around the Canadian Arctic continue to fall over Ontario this month. As a result, we continue to see very cold outbreaks followed by brief warmer and more seasonal periods. The Polar Vortex will again send very cold air to the Sault area at the start of the weekend. Nighttime lows will approach -30°C and daytime highs will struggle to climb above -20°C.

The polar vortex is again pushing frigid air into the Sault area on Friday under mostly sunny skies. Morning lows will be near -25°C and afternoon temperatures will remain below -15°C. Even light northeast winds will be enough to bring wind chill values ​​near -30.

The cold snap continues on Saturday, with daytime highs near -15C under mostly sunny skies.

A southerly wind arrives on Sunday to push cloud cover into the region along with light snow and warmer air. As a result, temperatures are expected to climb to nearly -5°C by late afternoon. A few centimeters of snow are likely by nightfall. Colder air returns again by the middle of next week.
