A severe thunderstorm yellow watch has been issued for Toronto and the GTA as the first heat spell of the season will be wrapping up. The affected areas also include York Region, Peel Region, Halton Region and Hamilton.
Environment and Climate Change Canada issued the alert after two humid days of temperatures in the 30s.
The severe thunderstorms are expected to hit late this afternoon and into the evening along with a sharp cold front. Main threats with these storms include winds gusting between 90 to 110 kilometres per hour and up to quarter-sized hail.
The strongest storms will remain further west along Lake Huron shorelines and into southwestern Ontario, where damaging winds and large hail are possible.
A yellow heat warning also remains in effect for those same areas, but temperatures are set to drop dramatically following the storm with highs on Wednesday only reaching 15 degrees.
The cooler weather will continue through the weekend before another expected warm-up next week.
