Rainy weather returns Tuesday to southern Ontario
Monday, August 18, 2014, 10:02 AM - Soak up the sun today if you can, southern Ontario. After a below-seasonal weekend, temperatures won't be much warmer this week, and there's rain on the way.
There's a low pressure system gathering strength to the west of the region, and it's going to make for a soggy mid-week, delivering 10-15 mm of rain to the Greater Toronto Area by the end of Wednesday.
It starts Tuesday evening, affecting mainly the Windsor-Sarnia area and the Lake Huron Shores, reaching the Kitchener-Waterloo area by midnight and slowly rolling through the GTA through the morning. It will have reached eastern Ontario by the end of Wednesday.

Although temperatures won't be too toasty, there might be enough humidity in the air to fuel thunderstorms, Weather Network meteorologist Brett Soderholm said early Monday morning.
"If this system organizes more tightly, it could give rise to a few embedded thunderstorms," he said of the approaching low.
The system's departure from the region will be slow, and people shouldn't expect really clearing conditions until after Friday, although Wednesday will be the only day where any significant rain is possible.
Temperatures for the week will be cooler than you'd expect from summer, in the low-to-mid 20s, for most of the week, not much different from Sunday, but certainly not as downright chilly as Saturday was.
"It's still below seasonal, but at least we're expecting relatively clear conditions," Soderholm said of Monday.
