Laurissa Anyas-Weiss, content producer

June 25, 2009 — Southern Ontario and Quebec could see thunderstorms with the risk of severe thunderstorms beginning this afternoon and lasting into the overnight period.

A Prairie cold front moving south east across southern Ontario and Quebec today will meet with daytime heating causing thunderstorms.

Some of these thunderstorms may become severe with the possibility of localized flooding, damaging winds and hail. Rainfall amounts could vary significantly across the region as is typical with thunderstorms. While most areas will likely see some rain, amounts will range for nothing to possibly over 50 mm. Hail is possible with the most severe storm cells. Tornadoes are always possible with severe thunderstorms but in this weather situation the tornado risk is low.

With the risk of damaging winds and flooding associated with these thunderstorms, people should take precautions and keep up-to-date on the latest weather conditions.

Severe thunderstorms watches and warnings are already in effect in some areas.
