The summer-like temperatures and sunny skies from early this week will be paused as a Texas low will bring a super-soaker event to southern Ontario, with upwards of 40 millimetres of rain expected in Toronto.

The low-pressure weather event will reach southern Ontario by Thursday morning, bringing soaking rains to the province through Friday.

Across much of southern Ontario, 30-50 mm of rain is expected, while northeastern Ontario regions like Timmins, Sudbury and Sault Ste. Marie can expect 50-75 mm. Equivalent amounts of high rainfall will be experienced in Windsor and London, Ont.

For Toronto, the rain is forecasted to start around 4 a.m. on Thursday and persist throughout the day. By approximately 8 p.m., the rain will get heavier, with 3 mm of rain an hour expected to fall by midnight.
