‘Incredible snow totals’: Squalls to hit parts of Ontario, up to 80 cm possible

Several parts of Ontario are set to see “incredible snow totals” over the next few days due to a shift in temperatures over the Great Lakes.

Several parts of Ontario are set to see “incredible snow totals” over the next few days due to a shift in temperatures over the Great Lakes.

Water temperatures across the lakes has been at record mild levels given the calm fall so far, Global News meteorologist Anthony Farnell said.

However, a looming change in temperature between the lake and the air will create “ideal conditions” for lake effect snow, he added.

“Areas downwind of all five Great Lakes will see some incredible snow totals this upcoming weekend and travel will be difficult at best,” Farnell said.

“The Lake Huron and Georgian Bay snow squalls will quickly intensify early Friday morning and continue right into early next week.”

Farnell added because water temperatures are still so mild, areas right near those will see a heavier, wet snow that will limit amounts at least initially. As the wind shifts slightly, the snow squalls will also shift, bringing the heaviest snow amounts to different communities depending on the day.

In the most intense squalls, snow rates could reach as high as 8 cm per hour with thunder and lightning, he said.

“By Monday, snow totals could reach as high as 80 cm under the more persistent snow squalls. Much of the GTA will miss out on the heaviest snow, but part of the north and west end will see amounts that could top 10 cm by Monday,” Farnell said.
