Spectacular weekend coming to southern Ontario, but with a small catch

Spectacular weather is expected for most of the weekend across southern Ontario, but once again, we do have a looming risk for showers and thunderstorms at times.

Gorgeous late spring weather is likely for the start of the weekend, with full sunshine Friday afternoon and evening, accompanied by comfortable temperatures, low humidity, and little wind.

Still quite cool to swim

Saturday's weather will be a pleasant day for most outdoor activities, with a mix of sun and clouds and near seasonal temperatures.

However, these conditions are still rather cool if you are hoping for an early season swim.

The catch...Rain Saturday night lingers into early Sunday

For Saturday night, widespread rain (thunder possible) will track across southern Ontario. For the most part, the timing looks good with the threat of rain primarily being through the overnight hours. However, if there is a slight change in the timing, then this could impact outdoor plans late Saturday evening, so please be sure to check back for the latest updates.

The region with the highest risk of seeing rain before sunset will be across southwestern Ontario, to the west of London, including the southern shores of Lake Huron.

Unfortunately, it now looks like the threat for showers will linger into Sunday morning, especially for the Greater Toronto Area and for areas to the east of the GTA. However, some sunshine will return for Sunday afternoon, and temperatures will be near seasonal.

During Sunday afternoon, an isolated shower or thunderstorm could pop up, but most of southern Ontario will have a dry afternoon and evening.

Beyond that, warmer weather is expected for next week with a few days of mid-summer like heat and humidity for the first week of June. With that warm up however, comes the risk of a few periods of rain and thunderstorms.

Tuesday, Wednesday and Thursday will be very warm and humid, as well. Our high temperatures will depend on the timing of the showers and thunderstorms, but any day with several hours of sunshine will have the potential to reach the upper 20s and possibly even 30°C, with the humidex well into the 30s.

If showers and thunderstorms do roll through earlier in the day, then temperatures will stay in the low to mid 20s. Regardless, we will have rather muggy conditions for a few days next week.
