Toronto in for 'temperature roller coaster' this week

Hold on to your coats, Toronto. While a warm up teased us with spring weather over the weekend, we’re in for a “temperature roller coaster” this week.

According to The Weather Network, a weak cold front dropping south over the province has brought temperatures back to more winter-like values. Hence Monday morning’s cold weather.

And the cold is expected to stay on Tuesday as well.

“Temperatures recover only marginally just above the freezing mark through the day on Monday and Tuesday, with highs running several degrees below average across the region,” states The Weather Network.

“While Tuesday will follow Monday’s chilly — but sunny — example, a change is in the works for mid-week as winds shift once again and warm air returns.”

A couple of sunny days are ahead, as milder temperatures roll in later this week across Southern Ontario.

By Thursday, it will be a sunny spring day in Toronto, with the high of 7°C.

But, naturally, with spring only just underway, that won’t be the end of the roller coaster quite yet, states The Weather Network.

A colder and rainy system will be moving into the region by the weekend.

“Southern Ontario will be the dividing line between warm weather to the south and colder weather just to our north. A significant system will track along this boundary,” said Weather Network Meteorologist Dr. Doug Gillham.

Gillham said the most likely scenario brings mild and wet weather to the region on Saturday, followed by a cool down behind the system on Sunday and for the start of next week.

“However, there is the threat for significant snow to our north including parts of Cottage Country,” said Gillham. “There are some models that bring the boundary further to the south and if that occurs, we would have the threat for snow/ice into at least northern parts of the GTA during the weekend.”

The Weather Network is forecasting colder than seasonal conditions to persist into the start of April, “although things look to take a turn for the warmer by the middle and end of next week.”
