A blizzard continues to form Blockbuster Lake Sunday in Ontario

Sunday will see the grand finale to a historic lake blizzard as a shift of winds sends fresh portions of southern Ontario facing heavy snowfall and dangerous travel bouts to end the weekend.

It has been a blizzard epidemic for centuries.

The town of Wyarton, Ont., reported 66cm of snow from Thursday night into Saturday morning, with more snow expected.

Some communities across the border in western New York have reportedly seen more than 70 inches of snow. That’s more than six feet, or nearly 200 centimeters, in some communities near Buffalo.

It’s hard to circumvent the incredible mountain of powder snow that it represents. It would take seven corgis stacked on top of each other to match the depth of the deepest snow near Buffalo. He is close to the average height of a professional basketball player. And that doesn’t even take into account the drift that occurred against homes and vehicles.

This type of snow is a legitimate emergency. Side streets are impassable, making it difficult for people to go to work or school, buy groceries, or even allow emergency crews to reach them if needed. It would take days – and a massive community effort – to extract the hardest hit areas.

The favorable framework that has buried western New York and parts of southern Ontario will begin to change as we head into Sunday. The gusts will continue from Saturday evening into Sunday morning before the winds begin to change direction.

The southwest winds that allowed these powerful snowballs to spin and attack from the northwest on Sunday afternoon, realigning the snow bands that will affect the area.

Snow Sunday will fall from Lake Huron and Georgian Bay, with the Bruce Peninsula, parts of the hinterland and the northern shores of Lake Ontario likely to contain most of the remaining snow from the event.

Finally, we could see additional snow accumulation by the end of Sunday. Snow accumulations collected from the southwest and northwest can form isolated ranges 15 to 30 cm thick in southern Ontario and rural areas. The heaviest totals are likely to be on the Bruce Peninsula, where an additional 30 to 40 cm of snow can fall.

It wouldn’t be a nice snowfall either. Winds will accompany Sunday, with winds of 50 to 70 km/h starting the day in a blisteringly cold weather in southern Ontario. Winds can reach 90 km/h along the Huron Coast.

The combination of heavy snowfall and high winds will cause more travel issues throughout the region. Conditions can quickly change from clear to near zero visibility for short distances in or near snowstorms.

Be prepared for sudden low visibility and very difficult travel in southern Ontario on Sunday. Avoid driving if possible.
