Ontario storm risk crops up again on Saturday before pattern turns

With the start of meteorological summer a week away, southern Ontario continues to bask in teases of weather reflection of the season.

Warm temperatures and multiple days of thunderstorms were on the menu this week, and Saturday could see more of the same offerings. The threat will be mostly non-severe in nature, but some locals in southwestern Ontario could see some powerful cells develop with large hail.

Strong winds, heavy rain, and small hail are the main risks across the south and east through Saturday afternoon.

However, there is a possibility for some storms in southwestern sections to become severe in nature, bringing the chance of large hail up to nickel-size, in addition to the downpours and wind gusts.

There’s the chance for storms to develop across the Greater Toronto Area (GTA) later in the day on Saturday, although many parts of the region may miss the stormy conditions if they remain south farther or north.
