After a relatively mild winter to this point, Torontonians are bracing themselves for a frigid weekend. 

On Friday, Environment Canada issued an extreme cold warning for the city. Expect some flurries this evening that will end sometime tonight with about two centimetres of snow. 

"A cold front will pass through the regions tonight. Very cold temperatures will follow in its wake, along with gusty northwest winds," Environment Canada said on its website.

The main issue for residents will be the blowing snow caused by winds reaching anywhere from 30 to 60 km/h. This could cause poor visibility for anyone trying to get around the city Friday.

"Ahead of this cold front, convective snow showers have developed and are producing locally intense bursts of visibility reducing snow. At their worst, visibilities could be as low as 250 metres," the weather agency said.

Motorists are advised to drive with caution. 

Bundle up Saturday

Environment Canada said the temperature is expected to dip to a low of -23 C overnight with the wind chill making it feel like -34 into Saturday morning. 

The forecast calls for mainly sunny skies Saturday with winds gusting 20 to 40 km/h. The high is -15 C but the wind chill is expected to make it feel like temperatures ranging from -30 to -35. 

The low Saturday night is slated to reach -23 C but the wind chill should continue, making it feel like -31. 

Weather conditions are expected to warm slightly Sunday with a low of -12 C, although it will feel like -17 with the wind chill, according to the Weather Network. 

"Extreme cold warnings are issued when very cold temperatures or wind chill creates an elevated risk to health such as frost bite and hypothermia," the government agency said. 

Toronto officials extended their extreme cold weather alert today. The city declares this alert when temperatures are forecasted to hit -15 C or -20 with the wind chill.
