Ontario's 2024-25 winter forecast predicts 'messy storms' and a 'duel' between cold & mild

Brace yourselves, Ontario — winter is coming, and it's shaping up to be a much more traditional winter than what we've seen recently.

The Weather Network's official 2024-25 winter forecast is out, and it's looking like Ontario's weather is in for a proper winter this year. After last year's record-breaking warmth, this season promises a mix of chilly temps, messy storms and a few surprises — so consider this your final warning to put your winter tires on if you haven't already.

According to The Weather Network, Ontario will start December with a sudden plunge into cold, wintry conditions. This sharp transition should bring plenty of lake-effect snow, offering a strong kickoff for ski enthusiasts and those hoping for a white Christmas.

But don't get too cozy — January and February are expected to see a "come-and-go" pattern, where periods of mild weather will often outshine the colder stretches.

Whether you're in Toronto, Ottawa or Thunder Bay, here's what you can expect for the 2024-2025 winter season.

A tale of two Ontarios

The divide between northern and southern Ontario is expected to be stark this winter. Northern regions like Thunder Bay and Timmins should brace for a snowy winter thanks to an active storm track near the Great Lakes. Meanwhile, southern areas—including Toronto, Ottawa and London — will likely see a series of messy storms with rain, ice and occasional snow, leading to below-average snowfall overall.

That said, The Weather Network warns that a slight southward shift in the storm track could flip the script, turning southern Ontario's mild winter into one marked by heavy snow. So, while you may not need a new snowblower just yet, it's probably wise to keep your shovels handy.

Will we get a white Christmas?

It's looking promising for many Ontarians. The December chill and active storm pattern suggest a higher chance of snow sticking around for the holidays, especially compared to last year. Even southern Ontario could wake up to a snowy Christmas morning, as the colder start to the season will boost the chances of wintry weather.

While this winter won't be as mild as last year's, it still has its share of unpredictability. From ski-ready December to unpredictable storms later on, Ontario's winter is bound to keep everyone guessing.

As The Weather Network puts it, "Winter will attempt to redeem its reputation" this year. Whether it's ice, rain or snow, one thing's for sure: It's time to bundle up and enjoy whatever the season throws our way.
