Ontario: Wild mix of heavy snow, freezing rain, strong winds to end the week

  Ontario: Wild mix of heavy snow, freezing rain, strong winds to end the week Location will play a key role in the precipitation types involved with a system pushing through Ontario on Thursday.Rain, heavy snow and powerful winds -- the system cutting across Ontario on Thursday has a little something to give to much of the province. Snowfall warnings are in place across the northwest, while just scattered rain showers will persist into the evening for the south. That dividing line between the rain and the snow will also complicate travel north of the Ottawa Valley with the risk for freezing rain stretching into early Friday morning.

The week opens on a quieter note for southern Ontario, though it won't be without its showers as a weak clipper slides through the Great Lakes region. The next major weather-maker takes aim on the area through mid-week, where forecasters are watching for a developing Colorado low set to bring rain, snow, and a wintry mix to parts of the region. More on the timing of when this system intensifies, plus a look at a winter-like storm that also threatens southern Ontario this weekend, below.

MORE WIDESPREAD IMPACT BY WEDNESDAY WITH A COLORADO LOW

Forecasters are closely watching a Colorado low expected to take aim on Ontario by Wednesday -- one that will have more widespread impacts on the province.

While the system won't develop until early Tuesday, initial computer model guidance suggests the storm will bring strong winds and bouts of heavy rain and snow into the Great Lakes region through Wednesday. This will make for a messy mid-week across much of the province. For those east of Lake Superior and across the Nickel Belt, as much as 30 cm of snow is possible with major impact to travel expected.

"This system will intensify as it tracks into the Great Lakes region on Wednesday, bringing potentially damaging winds with gusts between 60-80+ km/h expected," says Weather Network meteorologist Dr. Doug Gillham, adding that gusts could reach as high as 100 km/h, especially across the Niagara region. "Isolated power outages are possible, and lakeshore flooding is a major concern from Long Point to Fort Erie."

Rain is expected to begin pushing into southern Ontario through the overnight hours Tuesday into Wednesday, with snow and a wintry mix expected north of lakes Huron and Superior by Wednesday morning.

While most precipitation in the south is expected to stay as rain, Arctic air wrapping around behind the low pressure centre will mean a bit of temperature drop across the south between Wednesday and Thursday, with the potential for some wrap-around and lake-effect snow. That risk comes courtesy of the intense winds with the gusty conditions expected to persist into Thursday.

"This will bring a significant threat for snow and freezing rain to a large part of southern Ontario including the GTA Saturday night and Sunday," says Gillham. "The messy mix could change to rain before ending."

Currently, the greatest snow and ice accumulations are expected north of Lake Ontario, but be sure to check back for updates as the forecast details of this storm will change over the week.

The potential for more wintry weather is set to return for the start of December as a widespread cold pattern develops across much of Canada and an active storm track locks in over the Great Lakes.
