Severe thunderstorms possible this evening. This is an alert to the potential development of severe thunderstorms with large hail, damaging winds or heavy rainfall..Monitor weather conditions and listen for updated bulletins.
A hot and very moist airmass over Southern Ontario has created conditions favourable for the development of showers and thunderstorms. Although thunderstorm development is expected to be isolated, any that do develop will be very slow moving and could produce torrential downpours with greater than 50 mm of rain as well as large hail.
