Wild weather swing expected in Toronto with fierce, but fleeting, temperature plunge

After a few days of mild temperatures, Toronto and much of the GTA will experience a significant drop on Saturday, with a forecasted daytime high of -4 C.

Toronto’s largely absent winter will roar back with a dramatic temperature plunge expected Friday night and into Saturday, but the milder temperatures that have marked the season will soon return.

Temperatures on Friday were expected to peak at around 5 C, but hit 9.4 C at Pearson Airport, breaking the CityNews 680 Weather Guarantee of $33,300.

The jackpot winner will be announced on-air on CityNews 680 around 7 a.m. Monday.

The mid-Friday warmth, however, will be obliterated when a system from the northwest brings whipping winds and cooler air heading into the evening.

Winds could peak between 30 to 50 kilometres per hour on Friday evening, with lows hitting around -7 C.

Overnight, temperatures will further plunge to around -15 and by Saturday morning it’s expected to feel like -20 with the wind-chill.

That’s prompted the City of Toronto to open an additional warming centre at 58 Cecil Street. It will open Friday night at 5 p.m.

Warmer air is expected to return by Sunday, with temperatures back to balmy double-digit territory by Tuesday and Wednesday.

That heat will also come with some rain, and even the risk of thunderstorms, CityNews meteorologist Natasha Ramsahai warned in her seven-day forecast.
