Rain, storm risk returns to southern Ontario, but don't write off the weekend

The first weekend in May won't be the promising start for outdoor weather in southern Ontario, but it won't be a washout, either.

Saturday looks to be better of the two days if you do have plans to travel or to do any outdoor activities, but rain and an isolated risk of thunderstorms will move in come the evening time.

YOUR MAY OUTLOOK: Spring into summer or a stalling spring ahead, Canada?

A similar situation will unfold again on Sunday, but an earlier timing for the showers and thunderstorm chance in the afternoon could spoil a round of golf or other outdoor happenings.

Showers and storm risk on the weekend

Saturday started off under fair conditions in southern Ontario, but some light afternoon sprinkles will find their way into cottage country, along the Lake Huron shores and in eastern Ontario.

Any plans across the Greater Toronto Area (GTA) should go off without a hitch as conditions remain dry but cloudy throughout the day.

It’s a short-lived reprieve, though, as a warm front will roll into the southern Ontario, bringing the risk for isolated thunderstorms.

The cold front associated with the low is expected to bring scattered thunderstorm towards northern regions through the evening and overnight period.

Showers and a risk for thunderstorms will return through the mid-afternoon hours on Sunday for the GTA and areas west. Showers will linger into the evening for eastern Ontario.

For the most part, the heaviest rainfall will stay to the north around Sault Ste. Marie and Sudbury, where it is much needed.
