The peak of tornado season is not too far off across Canada as you can see by the chart below.

The map below shows the average annual number of tornadoes across Canada. As you can see by the map below, most of the tornadoes in Canada impact the southern Prairies and Ontario. Southwestern Ontario averages the highest number of tornadoes annually.

When you think of large, powerful tornadoes, you normally think of the U.S. Plains, but these monster storms do occasionally impact Canada. The video below, courtesy of YouTube and Tornadoevideos.net, shows a very large, F5-rated wedge tornado that impacted Manitoba back on June 23rd, 2007.

------------ In the meantime...

--There will be a surge of unseasonably warm air into the Prairies and eventually northwestern Ontario starting early next week.

--The weather will remain cool and wet into Monday across most of Newfoundland and Labrador as a closed, upper low pressure system sits across the region.

--A fairly potent storm system will spread another batch of rain and thunder across the southern half of Ontario Monday and Monday night. There is a slight chance of severe storms over the southern half of southwestern Ontario.

--Expect a period of cool and wet weather to build across British Columbia during the middle of next week, but the weather looks quite nice through this Saturday.
