Just in time for the first day of December, Environment Canada is warning Ontarians that there’s a pretty intense weekend of wintery weather ahead. According to Environment Canada, a huge storm is heading for southern Ontario, and up to 10cm of snow is expected to blanket the region on Sunday. Ontario’s winter weather is officially arriving this weekend, and it’s going to be hectic!

Earlier this week, The Weather Network reported that southern Ontario’s winter weather would be setting-in this weekend, as an approaching Colorado low sweeps across the Great Lakes alongside a huge new storm.

The low is predicted to bring between 10 cm and 15 cm of snow to the region on Sunday, which is expected to have a “major impact” on travel times and conditions in the GTA.

In addition to travel warnings in Toronto, Environment Canada has now released several public weather alerts for the south of Ontario, and they’re predicting a pretty hectic end to the weekend.

According to their latest weather statements for the region, "A strengthening low pressure system is expected to bring a messy mix of weather to the area, beginning early Sunday morning."

Updated just before 11 a.m. on Saturday morning, Environment Canada warns of "a wintry mix" on Sunday, that is likely to include freezing rain, strong winds and snow.

In their most recent weather statement, Environment Canada predicts that some areas in southern Ontario could see "several hours of freezing rain or ice pellets" on Sunday morning, before "light snow and freezing drizzle" Sunday afternoon.

Light snow is expected to continue through Sunday night before tapering off early on Monday morning.

If that wasn't already a harsh re-introduction to the winter, strong wind gusts of up to 70 km/h are also expected across the region. Yikes!

It's not yet certain how the weather will shape-up on Monday, but Environment Canada predicts between 5 and 10 cm of total snowfall or ice pellets by Monday morning.

With snow and freezing rain expected to hit the GTA and beyond this weekend, commutes are expected to be a nightmare for both land and air. 

If you had plans for any unnecessary travel this weekend- cancel them! Curl up with a good book or movie, and just wait this one out.

Be sure to keep checking for updates as the weekend progresses, as the forecast details of this storm could still change.
