December 27, 2011 — Updated: 9:45 p.m. EST - A moisture-filled system is set to sweep through eastern Ontario and Quebec, bringing heavy snow to some areas.
People heading back to work or planning more holiday travel this week may want to bring along a snow brush.
A low-pressure storm system is developing over the southern United States will push into central Canada on Tuesday and rapidly intensify.
Precipitation will start as light rain, but as temperatures drop Tuesday evening, the rain will change to snow. Parts of eastern Ontario, including the Ottawa Valley, could see up to 15 cm by Wednesday.
Quebec is expecting about about 10 cm of snow and close to 20 mm of rain.
A winter storm warning has been issued for Quebec City, the Laurentians and the Saguenay region.
The system will also bring a wintery mix to parts of southern Ontario, including Toronto, Hamilton, Niagara, Kitchener-Waterloo, Kingston and cottage country.
The region will also initially see rain throughout the day Tuesday, but a cold front associated with the system will cause temperatures to plunge Tuesday night, meaning any subsequent precipitation will be snow.
The drastic drop in temperature has resulted in flash freezing north of Owen Sound. The freezing conditions will move into the GTA in the overnight hours. People are being encouraged to shovel their driveways prior to going to bed, before the cold sets in.
South of Latchford, Highway 11 was temporarily closed in both directions following a car collision. Several accidents have been reported on GTA roadways as well.
Weather Network Network meteorologist Brian Dillon says the Greater Toronto Area will see slight accumulation in the overnight hours, and cold temperatures on Wednesday: “The snow will continue to fall Tuesday night. Along the lakeshore, accumulation will be close to 5 cm,” he explains, “but north of the 401, accumulations should be closer to 10 cm. temperatures will drop overnight and, with the windchill, it will feel like -20°C on Wednesday.”
