Quick Update on Severe Thunderstorm Threat Today

Severe weather threat from southern Ontario to New Brunswick later this afternoon and early evening...

Temperatures are quickly rising from southern Ontario to southern Quebec under sunny skies, and this is causing the atmosphere to become more unstable. Combine this with high humidity and a weak front to the north and the recipe is in place for thunderstorms later this afternoon and into this evening.

The region will also be under the southern edge of the jet stream, which will energize the thunderstorms and lead to possible damaging winds and small hail as they track toward the east-southeast.
