Fall’s first snow for Toronto, Niagara and Ottawa will test drivers’ patience – The Weather Network

After a weekend of snowy weather to the north, it’s finally southern Ontario’s turn for some winter weather.

The first impactful, snowy system of the season for the Greater Toronto and Hamilton Area, Niagara, and Ottawa will move in on Wednesday morning, possibly bringing whiteout conditions with it. Commuters can expect slow and slippery travel during this time, so plan leave plenty of time to get to your destination on time, and safely.

For those in near Georgian Bay, from Cobourg to Kingston, and along Highway 21, commuters in these areas should consider avoiding travel if possible. Motorists should expect hazardous winter driving conditions and adjust travel plans accordingly.

A number of snow squall and blowing snow warnings, and winter weather travel advisories ,are in place.

Whiteout conditions possible with first snowfall on Wednesday

The difference in air temperatures over the Great Lakes and over land will serve to enhance the snowfall as it moves inland off of the lakes on Wednesday. This will also result in bursts of heavy snow and embedded snow squalls, making for a messy and dangerous situation.

The snow will begin early Wednesday morning across southern and eastern Ontario, just in time to impact morning commutes. All major routes will be impacted by the snow, but commuters in the southern Niagara region, as well as along Highway 401 east of Toronto up to Kingston, will be at an increased risk of significant snowfall accumulations and whiteout conditions.
