The recent rain in southern Ontario has been intense enough set a new daily rainfall record at Toronto Pearson.

As of 2:00 p.m. Tuesday, the airport had seen 22 mm of rain. By Wednesday morning that climbed to 28 mm, replacing a 1964 daily record of 17.5 millimeters.

It's all part of a weather trend that's set to continue for at least a few more days, according to Weather Network meteorologist Matt Grinter.

"The effects of the current system affecting the region will linger into the weekend," he says.

Up to 20 mm of rain could fall in southern Ontario by Thursday, followed by scattered showers that will persist through to Saturday morning.

Eastern Ontario could see up to 50 mm of rain.

"From Saturday afternoon to the evening, another clipper system will move in, bringing another round of light rain," Grinter adds.

The start of the next work week looks like it will be relatively dry but Toronto's 14-day forecast is hinting at consistently wet weather well into Mid-May.
