The First Snowfall Possible Saturday Morning for Parts of Southern Ontario As the Season’s First Snowstorm Takes Aim at Northern Ontario This Weekend

As colder temperatures and the leaves fall off the trees, it’s only a matter of time until we see the first snowfall of the season. And for some parts of Central Ontario and the higher elevations through the Dundalk Highlands, that time is Saturday morning. Although little to no accumulation is expected as is usually typical with the first snowfall of the season and should melt on contact with the ground. Temperatures will rise into the upper single digits on Saturday so if any snow does manage to stick to the ground it will quickly melt after sunrise.

Lake effect showers are expected to develop off of Lake Huron and Georgian Bay late Friday and into Saturday affecting areas east of those lakes. As we head into the overnight hours we’ll see temperatures in the northern parts of Central Ontario such as Sundridge, Algonquin Park and Huntsville drop to near the freezing mark.

This will allow for some flurries and wet snow to mix into the lake effect flurries between midnight and before sunrise (around 7 am) in the morning. The same is true for the higher elevations just to the northwest of Orangeville although this is more questionable and may not occur. As mentioned, temperatures will quickly warm up after sunrise so if you aren’t up early in the morning (or up late) then you likely won’t see any snow.

The same can’t be said for parts of Northern Ontario which is currently on track to see their first snowstorm of the season with up to 20cm of accumulation possible by the end of the weekend. This is courtesy of a combination of lake effect snow off Lake Superior and an Alberta Clipper that will move in from the US starting Saturday. Most areas can expect between 10-15cm including Thunder Bay, Geraldton and Wawa with locally up to 15-25cm, especially with those areas that see the lake effect snow.

Have a great weekend!!
