Polar Vortex over Ontario for this week...
Arctic air is expected for Sunday and most of next week, with the coldest conditions of the season set to flood through the province.
In parts of northern Ontario, the temperatures will drop about 24°C in just 24 hours, and roughly 30°C in 36 hours.
For many areas, these will actually be the coldest conditions felt in years.
Kenora: Monday's forecast high of -28°C would be the first time plunging that low since January 2019
London: An overnight low temperature of -22°C will be the coldest since 2022......send warm wishes to Arawak
Ottawa: An overnight low temperature of -27°C will be the coldest since February 2023
Toronto: Tuesday's daytime high of -15°C will be the coldest daytime high since January 2019
Colder-than-normal temperatures are expected to continue into the final week of January.The drop isn’t as extreme in southern Ontario, but most areas will see a noticeable, 12-degree temperature tumble from Saturday afternoon to Sunday morning, with a chillier, 20-degree plummet expected across central regions.
The first cold day will be Sunday, with the Arctic air mass staying in place until Wednesday.
Several days of lake-effect snow are likely for the snowbelts next week, as well, but changeable winds should spread the snow over a larger region and prevent exceptional snow totals.
