November 30, 2010 — A low pressure system is sweeping across Ontario, bringing heavy rain to the south and snow to parts of the northwest. Quebec is also dealing with a decent drenching.
A snow shovel and an umbrella. You'll be needing one or the other, depending on where you are in Ontario over the next couple of days.
A low pressure system is sweeping across the province, bringing snow to the northwestern regions, a messy mix to the central regions and rain to the south. Up to 5 cm of snow is possible around Thunder Bay, while communities north of Pickle Lake could get buried in up to 20 cm.
When it comes to the rain, eastern Ontario and southern Quebec are forecast to take the biggest hit. Upwards of 75 mm could fall locally around Peterborough, Kingston, Ottawa and Montreal.
“The system will stall over their area even for Wednesday due to the high pressure that's currently located over Atlantic Canada,” says Elena Grigorenko a meteorologist at The Weather Network.
The city of Toronto could see anywhere from 30 - 40 mm of rain, and that has Toronto and Region Conservation authorities on alert. A high water safety bulletin was issued Monday afternoon and warns residents to take precaution around fast flowing rivers and streams.
“We will also see some strong winds with that system,” says Grigorenko. “Especially in southwestern Ontario where winds could pick up to 30 to 40 km/h, gusting to 50 to 60 km/h.”
While this seems like a major fall storm for the area, Grigorenko says it's definitely typical. “It is pretty normal for this time of year. That's when we get a lot of strong systems and lots of Colorado Lows or Texas Lows coming our way, so it is pretty normal to see this kind of precipitation at this time of year.”
The rain will begin to taper on Thursday and temperatures will start to cool to more seasonal values as well. There's also the potential for some flurries in the Greater Toronto Area by the end of the week.
