If you had your heart set on Sunday brunch on a patio tomorrow morning, you may want to take a rain cheque.

Environment Canada says showers and thunderstorms are expected to hit the region early Sunday morning.

The weather will likely clear up around noon but will remain cloudy with a daytime high of 25 C.

Monday looks as though it will be rain-free, however, Tuesday could be rainy one as the national weather agency says there is a 60 per cent chance of showers.
