From Alberta to southern Quebec, one word can sum up Monday: Frigid. Northwesterly winds swept Arctic air across a wide swath of the country.
It's expected to be the coldest morning of the winter so far in Toronto: around -18°C, feeling colder with the wind chill. The city was under an extreme cold weather alert throughout the weekend. Temperatures were so severe Monday morning, an elderly woman was found frozen to death on a driveway in the city's east end.
But what is extreme in one area is not unusual in another part of Canada. Take Edmonton, Saskatoon, or Winnipeg as examples. These cities are waking up to temperatures below -25°C on Monday before the wind chill is factored in.
Temperatures will improve in the Prairies as the week goes on. Southern Ontario only has to wait until Tuesday to swing back to more seasonal temperatures.
Warm air is coming to the region with a low pressure system from Alberta. While a warm up is coming, so is a storm. Exactly what it will bring is subject to change.
“Areas north of Barrie will likely get snow. But the type of precipitation for Toronto and areas to the south is uncertain. It looks like there will be freezing rain in southern Ontario,” says Dayna Vettese, a meteorologist at The Weather Network.
