Tuesday, June 24, 2014, 10:49 AM - After a weekend filled with sunshine and comfortable temperatures, high heat, humidity and thunderstorms are forecast across southern Ontario Tuesday.

IN DEPTH COVERAGE: Check back at 4 pm for details on the incoming storms and how they could impact your afternoon commute.

"Isolated thunderstorms will likely develop in southwestern Ontario first," says Weather Network meteorologist Kelly Sonnenburg. "Then as the cold front moves through, that will help to spark storms in southern Ontario through the afternoon and evening hours."

Last Tuesday, wind was the primary aspect of the storms across southern and central Ontario, but this time around, torrential downpours will be the greatest concern.

The rain prompted the Toronto and Region Conservation Authority to issue a statement Monday evening.

"Significant flooding is not expected at this time, but the forecasted rainfall will cause high flows and water levels in Greater Toronto Area creeks and rivers, resulting in unsafe conditions," the statement read. "Please exercise caution around all bodies of water. Please alert any children under your care of these dangerous conditions and supervise their activities."

Hot, muggy weather has settled into the region with humidex values in the 30s expect on Tuesday.

After the storms move through, temperatures will stabilize to near-seasonal levels for the remainder of the week.
