Ontario: Another round of snow and rain, chilly temperatures linger

Accure weather

Daytime highs will be in the single digits across southern Ontario on Wednesday as the below-seasonal temperatures continue to linger. Conditions will change by the end of the week and there is the potential for temperatures to approach or reach the double digits on Friday and Saturday.

A system will track through southwestern areas of the province late Wednesday and will bring snow to some areas and a mix of rain and snow to others. Details and timing, below.

After a March-like day Tuesday with strong winds, calm conditions return Wednesday and Thursday in the south, but temperatures will remain chilly, especially near the west end of Lake Ontario.

“Daytime highs for parts of southern Ontario will struggle to break the freezing mark. Northern Ontario will see sub-freezing daytime highs,” Sonnenburg adds.

Stronger winds will have subsided, but winds will still remain brisk across southern regions through the day. A mix of sun and cloud can be expected for the majority of the province. According to Weather Network meteorologist Matt Grinter, Toronto could be on track to mark a milestone with its streak of cooler-than-seasonal temperatures.

“This could be the 15th time in history that we haven’t reached 20°C before May in Toronto,” Grinter says.

On Wednesday afternoon a low pressure system will begin to bring light snow or a rain/snow mix to parts of southwestern Ontario. Some of this precipitation could reach western regions of the GTA including Niagara, Hamilton, Oakville and Burlington.

The wintry mix will continue through the overnight hours into Thursday morning with patchy freezing drizzle mixing in at times. By Thursday afternoon most of the precipitation should transition over to showers as the system tracks out of the province.


Temperatures look to temporarily climb back into the double digits Friday and Saturday for parts of the south.

Forecasters are watching a system tracking south of the Great Lakes for this weekend, with rain developing during Saturday across southern Ontario, accompanied by chilly temperatures. Wet snow is possible across the higher terrains well north of Toronto.

“Watching the potential for a system near the U.S. East Coast early next week. It could bring wet snow into parts of southern Quebec, especially the higher elevations,” said Weather Network meteorologist Dr. Doug Gillham.

Temperatures should recover somewhat for the middle and end of next week, still be below seasonal, but milder than the past two weeks.
