Freezing rain, heavy snow make for dangerous winter travel in Ontario, Quebec

Friday, November 26th 2021, 1:50 pm - Freezing rain and heavy snow spread across parts of northern Ontario and Quebec, while lake-effect squalls kick off the weekend in southern Ontario.

Bands of lake-effect snow will linger somewhat into Saturday morning, driven inland from the lakes by a cold, gusty wind. Beyond, a fast-moving clipper system looks set to bring a more widespread shot of snow, even to communities that have not yet had their first measurable accumulations. For a more detailed look ahead, see below.

INTO SATURDAY: WIDESPREAD WINTRY WARNINGS IN EFFECT, THREAT FOR 20+ CM OF SNOW OVER PARTS OF QUEBEC

Markedly colder temperatures have flooded southern Ontario, accompanied by gusty winds that brought a fair bit of lake-effect snow bands streaming inland off of Georgian Bay and Lake Huron.

Local accumulations of 5-15 cm are expected by Saturday morning in areas that experience the most persistent squalls, though they'll be tapering off early Saturday as the winds ease.

The system snow however, will continue over eastern Quebec, with 10-20+ cm expected between Friday night and Saturday. In Montreal, closer to 5 cm is likely, though this will be the first measurable snowfall of the season for the region and could catch some drivers off guard.

Strong winds in behind this system could produce blowing snow and reduced visibilities through the hardest hit areas of Quebec on Saturday.

"Quickly accumulating snow will make travel difficult," ECCC says. "While driving, be prepared for areas of near zero visibility. Consider modifying any non-essential travel plans."

Wet roadways and sidewalks will also be extra slick early Saturday across both Ontario and Quebec, as much colder air will have firmly settled in.

SUNDAY: MORE POTENT WINTRY CLIPPER BRINGS FIRST WIDESPREAD SNOW

A more potent wintry clipper will track across the Great Lakes and southern Ontario on Sunday, with forecasters watching the potential for widespread light snow.

A general 2-5 cm is likely, but higher totals are currently forecast southwest of the GTA, with 5-10 cm possible for places like London and Chatham.

The exact storm track is still uncertain however, and that will highly impact who sees the heaviest snow.

Near or slightly below seasonal temperatures will persist through early and mid next week, with the potential for a couple more clippers to track across the region. It is still too early to have confidence in the track and impacts of those systems.
