DON’T MISS: Freezing weather is inevitable. Here’s what you need to prepare
This week: Multiple snow flurries as cold weather sets in
On Tuesday, easterly winds blowing over Lake Ontario are forecast to develop a blizzard that, at times, will target parts of the GTA with short bursts of snow, slippery roads and reduced visibility. The storm may meander around coastal communities through Tuesday targeting the Hamilton area and western and southern parts of the Golden Horseshoe first before sliding north toward Toronto. Snow accumulations vary greatly in how heavily the precipitation develops, how long it is locked in one location, and also the fact that roads versus grass surfaces can accumulate snow at different rates. From flurries to a light dusting, even 5-15cm of snow is not out of the question for parts of the GTA. This won’t be for the snow either as another round will start with an incoming low pressure system. Rain will spread across southern Ontario Tuesday overnight and persist into early Wednesday. It will be the first widespread, wet snow threat for southern Ontario this season, and it will be the first snowfall for Montreal, Que., later Wednesday. Another 5-10cm of snow could fall. Typical of mid-November events, temperatures will be marginal with accumulations heavily influenced by elevation and distance from the Great Lakes.
WARNING: Break out the shovels, Ontario, snow is piling up on the way
Meanwhile, widespread below-season conditions are expected to prevail this week and beyond, with another strengthening picture of arctic air and temperatures more typical of early December at times. Temperatures on Friday and Saturday will be more typical of early to mid-December. Stormy conditions will end the week along with another round of lake effect snow in the snow belts. Lake snow will continue through the weekend and into early next week. This will be a multi-day high profile event that will cause travel issues for the hardest hit areas east of Georgia Bay and Lake Huron. The hardest hit areas could be the Buffalo and Watertown areas, with the potential for snow totals to exceed 50 cm. We will be keeping a close eye on the southern parts of the Niagara region as the heavy snowstorm could drift north into this area at times.
WARNING: These snow showers gave southern Ontario its first weekend of winter
