Slow moving system to bring significant rain to much of Ontario

Wednesday, June 11, 2014, 8:05 AM - After a calm and dry start to the week, rain made its way into southern Ontario late Tuesday.

"Showers moved into southwestern Ontario overnight, reaching the Greater Toronto Area by the early morning commute," says Weather Network meteorologist Kelly Sonnenburg.

A special weather statement was issued for some places, including the city of Toronto where upwards of 30 mm of rain could fall.

"Showers may be heavy at times and could result in local rainfall amounts in the 30 to 40 mm range," says Environment Canada in the statement. "Higher amounts may be possible in thunderstorms."

According to Sonnenburg, rain will persist through the morning and afternoon hours before clearing later in the evening.

"Rain moves back in with the passing cold front overnight into Thursday," Sonnenburg adds.

Even heavier amounts of rain are possible in northern and eastern Ontario, where rainfall warnings are in place.
