***The severe thunderstorm watch has been lifted***
A cold front is expected to sweep across southern Ontario later today raising the prospects of thunderstorms.
Environment Canada has issued a severe thunderstorm watch for Waterloo Region and surrounding areas.
It says conditions are right for the development of severe thunderstorms that may be capable of producing strong wind gusts, large hail and heavy rain.
It says those thunderstorms could develop this afternoon and end this evening.
