Friday, January 14, 2022, at 9 a.m. – Heavy snowstorms stretching into southern Ontario and Quebec early Monday. As much as 30+ cm of snow in the weather forecast for some.
In a winter so far that has really not been for much, all eyes are now on a significant storm that will affect large parts of central and eastern Canada early next week. Parts of Ontario and Quebec are queuing up for large amounts of snowfall, which could end up affecting travel by Monday. The exact storm totals will depend on the storm track and how close it is to the U.S. East Coast, but this will still be one to see in the coming days as it may bring some of the season’s biggest snowfall so far. More on what we know so far, and the bitter wind chill that starts this daring return to winter, below.

FRIDAY: BACK UP, THE EVIL WIND COLD BACK
After starting the week with some of the season’s coldest air so far, temperatures rose rapidly in the middle of the week, with daytime hours again rising above freezing over southern Ontario.
While splashes of sunshine start the weekend on Friday, a fresh north wind will look back on the wind chill, which will drop to the -20s and -30s for parts of the region.
Saturday will mostly remain sunny and cold as the eyes turn to the potentially significant snowmaker that threatens.
SATURDAY TO SUNDAY: THE STORM TO SEE SHAPES IN THE USA
The storm, which will affect large parts of eastern Canada early next week, is rooted in what is happening across the United States this week. Two systems – one tipping in from the northwestern Pacific Ocean and another rolling out from the prairies – will merge over the southern states and launch this disruptive system.
You may have noticed a huge increase in talk about this storm on social media. It is mainly run by weather enthusiasts from the state, who are anxiously awaiting their first marked thump of snow and ice this season.
This winter storm will track from the Mid-South right through New England and affect many major cities, including places like Atlanta, Charlotte and Washington, DC. Any winter weather in the southeastern United States is a big deal due to a combination of lack of winter driving experience and a shortage of equipment such as snow plows, salt / sand cars and winter tires.
The system could produce widespread snowfall from Georgia to Maine, with significant ice formation from freezing rain following the storm’s tracks into the northeastern states. Gusts of wind will make things worse and potentially provoke widespread power outages in some areas.
MONDAY: CONTINUATION FOR A TRUFFLE JOURNEY WHEN THE STORM SWEEPS INTO ONTARIO AND QUEBEC
We will have to keep a close eye on the system when it reaches the northeastern United States
After an up-and-down week with temperatures, cold air will be solidly anchored over the eastern half of Canada this weekend and beyond.
As the system pushes into the northeastern states this weekend, moisture will spread across the international border into the cold air parked over Ontario and Quebec, leading to a period of snow throughout the day Monday through early Tuesday.
This is a complex forecast with lower than normal confidence in the system traces. Right now, however, computer models suggest that heavy snowfall is to be laid across southeastern Ontario late Monday morning, continuing all day, with major impacts likely along 401 toward Kingston and into the Ottawa Valley. It appears that a shard of 15-25 + cm of snow is possible somewhere in eastern Ontario and southern Quebec through Tuesday.
The exact trace of this system will determine where the greatest amount of snow falls and even where the accumulating snow falls at all. A track slightly to the west would put GTA in play to collect snow, while a track slightly to the east would leave GTA on the western edge of the snowfall.
“We are still days away from the formation of this low pressure system. A small meander in the track or its location can really tip snowfall accumulations in one way or another,” explains Jessie Uppal, a meteorologist at The Weather Network. “Whatever the great snow potential is there.”
Snow in total close to 10 cm is possible for most of the GTA, with a wide range of totals for the Niagara region – from almost 10 cm for Hamilton to 20-25 cm across the eastern parts of the region, including Niagara Falls and Fort Erie.
However, all precipitation associated with this storm is expected to fall as snow thanks to all the cold air that can interact with centered over Ontario and Quebec.
Be sure to return often on the way into this weekend as forecasters get a clearer picture of what this storm will look like as it approaches Ontario and Quebec.
