An intense thunderstorm continues to develop near Hawkesbury, Ontario on the Ottawa River Saturday afternoon. Scores of thunderstorms developed ahead of a cold front and produced two tornadoes in the region. ValleyWX Pic
The summer onslaught of severe thunderstorms in our area continued this past weekend with reports of two separate tornadoes locally, hail, and a couple struck by lightning in Montreal. Severe thunderstorms fired up in the warm and humid air by noon on Saturday across Eastern Ontario and then southern Quebec. I was crisscrossing the farm country in eastern Ontario between Highways 401 and 417 and encountered very strong down burst winds and torrential rains. I managed to miss both twisters despite being right in between the storms. The first struck Berwick, Ontario near Cassleman Saturday afternoon. With winds of around 100km/h the storm snapped scores of trees and damaged some homes. Environment Canada has determined the storm to be an F-0. A second F-0 tornado struck near St. Lazarre late Saturday with 120km/h winds causing damage at several homes and also toppling trees. Meanwhile the storms produced heavy rain in Montreal and intense lightning. The lightning struck a couple standing under a tree in east end Montreal just prior to the International Fireworks festival at Laronde. They are both in serious condition in hospital. Flooding was also reported again along the 40 near L'Acadie circle forcing Transport Quebec to close the road for about an hour.
Yesterday was quiet, much drier and cooler than it has been all month. Today it is muggy again with heavy rain showers this morning. There is a risk for the morning hours of more scattered thunderstorms. The balance of the week will be warm and humid with scattered showers, much the same way this entire month has been.
