Winter is Coming! Snow Predictions for November

Snow is on the way! This article from The Weather Network calls for snow coming this weekend.

Two rounds of snow squalls and system snow — forecast confidence is high that wintry weather will impact much of Ontario.

Winter storm and snow squall warnings remain in place for a large portion of northern Ontario, as up to 20 cm are possible for parts.

Meanwhile, a special weather statement has been issued for southern portions of Ontario and Quebec, primarily for those east of Georgian Bay.

“Forecast confidence in snowfall amounts due to snow squalls is low due to the high variability of snowfall rates associated with snow squalls,” explains Weather Network meteorologist Dr. Doug Gillham. “Forecast confidence is high that strong winds will accompany these squalls and low pressure system this weekend.”


Snow squalls will impact snowbelt regions Friday, followed by a low pressure system that will move in Saturday bringing both rain and snow across southern Ontario and Quebec.

“As the system departs, snow squalls will intensify once again on Sunday,” Dr. Gillham adds.

As of Friday morning, several bands of lake effect snow have already affected northeastern Ontario from Manitoulin Island to Sudbury and east to North Bay.

While temperatures continue to drop Friday morning behind the cold front, rain is expected to transition into snow, continuing Saturday afternoon into Sunday morning for Grey-Bruce and Central Ontario, Environment Canada reports. Blowing snow and poor visibility are certainly of concern with this system.
Wind gusts up to 80 km/h could make for treacherous driving conditions.

“Travelers should prepare for winter driving conditions,” warned Environment Canada in a special weather statement issued early Friday morning.

Weekend Breakdown:


Snow squalls will taper Saturday as a low pressure system from the U.S. Midwest moves in. Precipitation from this system should begin through Saturday morning and spread northeast and intensify throughout the day.

Areas south of the 401 corridor will see mostly rain and some mixed precipitation.
Areas along a rough line from Sarnia to Kitchener to Markham to Peterborough can expect mixed precipitation. Snow will become the dominant precipitation type for areas north of these communities with snowfall totals of 5-10+ cm possible.
The heaviest snow is expected even further north with areas between Sudbury and North Bay possibly seeing 10 to 20+ cm.


The system snow will start to taper off Saturday night, but will be replaced by strong winds, which will lead to the reformation of snow squalls overnight Saturday and into Sunday.

РMixing is forecast for southern Quebec Saturday night into Sunday. This system could bring significant amounts of snow between Témiscamingue and Chibougamau, Environment Canada reports.

-Gusts up to 100 km/h are possible in the Niagara region late Saturday night into Sunday, tapering by midday.

-Gusts up to 90 km/h are possible on the eastern side of Lake Ontario, tapering Sunday afternoon.

-Northwesterly winds will cause snow squalls to move off Lake Huron and Georgian Bay with snowbelt regions receiving the bulk of the snow.

-Gusts between 50 and 80 km/h along the shores of Lake Huron and Georgian Bay are possible.

-Snowfall totals for Sunday are difficult to nail down due to the variability of snowfall rates within the squalls, but the hardest hit areas could receive 15+ cm of snow.
