Through Thursday: Storm risk returns for southern Ontario

We saw a powerful line of thunderstorms sweep off Lake Huron on Wednesday afternoon, prompting widespread tornado warnings from Owen Sound to Guelph as areas of rotation developed in the storms.

Thursday shouldn’t see anything as rambunctious as we saw on Wednesday, but remain on the lookout for a risk for thunderstorms as you go about your day.

We’ll see enough storm energy across southern Ontario that a risk for scattered thunderstorms will crop up in the heat of the day from Windsor all the way to the National Capital Region and beyond into Quebec.


While storms should stay below severe limits in Ontario, some of the stronger storms could produce small hail and heavy rainfall.

Conditions will remain warm and muggy through the afternoon hours on Thursday, with high temperatures in the mid- to upper-20s for most of southern Ontario. Humidity will push those feels-like values ​​into the upper 30s, as well, making for another sultry day in the Greater Toronto Area and north toward Ottawa.
