(Evan Mitsui/CBC) (BUTTON) Load image Open image in new tab A brutal weekend of winter weather will soon hit its climax with a snowstorm expected to hit the Greater Toronto Area starting late Sunday morning. Environment Canada issued an orange winter storm warning that predicts between 20 and 40 centimetres of snow for muncipalities across the GTA. Here’s a timeline of what to expect and when, based on information from Environment Canada and CBC Toronto meteorologist Colette Kennedy. It is worth noting current weather models aren’t fully in agreement. CBC Toronto will update this story as we learn more. Sunday morning: Storm set to hit GTA around 11 a.m. Lake-effect snow may start falling by the shores of Lake Ontario this morning. But current models expect the actual storm to hit around 11 a.m. and continue throughout most of the day. It'll be a high of -8 C, but feel closer to -21 C. This storm could drop up to 40 centimetres of snow by the time it’s done, according to Environment Canada, with higher amounts possible in specific areas. Right now, it looks like the heaviest snow will hit from 2-7 p.m, or possibly a little later in the day. Visibility will be near zero at times in blowing snow with winds gusting to 50 km/h, Environment Canada said in the orange warning.

Environment Canada warns disruptions to transportation and utility services are likely to occur across the GTA. Drivers are being warned to have emergency kits prepared with food, water, blankets and extra winter gear for both long and short drives this weekend, Ontario Provincial Police Sgt. Kerry Schmidt said on social media Friday. "Having these supplies in your vehicle could make the difference between having a good day that you'll get through or a really, really rough one," he said. Sunday evening: Heavy snow gradually tapers off Don’t be surprised if it’s still snowing hard in the evening, and watch out for snowplows on the roads. "We'll be doing our very best to keep the city moving," Toronto city manager Paul Johnson said ahead of the storm. That heavy snow will transition to light snow closer to midnight. It'll be a low of -13 C with a wind chill of -22. * 'Swirling pool' of Arctic air bringing deep freeze, 'significant' snow to Toronto area: Environment Canada * Toronto braces for bitter cold as advocates warn shelters, warming centres may not meet demand Monday morning: Concerns ahead of morning commute Light snow is expected to continue overnight. If we do get hit with a big dump of snow Sunday, the snow-clearing efforts will likely still be underway by Monday morning. There is a chance lake-effect snow could still be falling by 7 a.m., Kennedy said, with some areas seeing snow squalls. However, she thinks it's more likely the storm system will have cleared out. There will be a wind chill of -22 in the morning that will warm slightly to -15 in the afternoon. Brace yourself for a slow commute and consider lending a hand with the shovelling on your street. "Neighbours helping neighbours, that's the Toronto way," Mayor Olivia Chow said. More Stories Like This The related links below are generated automatically based on the story you’ve just read.
