Umbrella weather: Rainy week ahead for Ontario

Sunday, April 27, 2014, 12:34 PM -

If you're hoping for a sunny end to April, you might want to readjust your expectations.

Thanks to a slow-moving system moving in, the week to come will be rainy and colder than seasonal.

"This is the same system that's bringing the severe weather threat to the US over the next few days," Weather Network meteorologist Gina Ressler said Sunday. "It will begin to move into southwestern Ontario Monday evening, likely reaching the GTA through the overnight."

And once it's here, here it will stay, with Tuesday and Wednesday bring the rainiest days, with a chance of showers on Thursday and Friday before the system moves on to Atlantic Canada.

"This is a very slow moving system, because we have a blocking pattern in the jet stream, so that means this is going to be a more prolonged event for Ontario," Ressler says.

The northern edge of that system is currently moving through the Prairie provinces, where it is heightening flood risk along riverside communities in Saskatchewan and Manitoba.

Some parts of the region were set to get more than 40 mm of rain by the time the edge of the system has truly moved on to Ontario and the east.

Ressler says it's still a little too soon to tell exactly what kind of totals to expect for Ontario, but estimates should be issued soon.

"Unfortunately, in addition to the rainfall, with these slow moving systems, we're going to see below seasonal temperatures," Ressler says.
