We are expecting a fairly quiet day weather-wise on Tuesday across Southern Ontario, with no major weather in place to cause widespread travel issues.

Because of this, there is nothing in the forecast that would suggest a strong likelihood of school bus cancellations.

The only area with any notable chance is the Parry Sound region under the Near North District School Board, where a snow squall warning remains in effect. That activity is expected to weaken overnight, making it questionable whether it will have any meaningful impact on the morning commute.

Even so, given this school board’s history of being particularly sensitive to weather conditions, we cannot completely rule out a surprise decision. As a result, we have assigned Parry Sound a 10 percent chance.

Outside of the Parry Sound area, no weather-related school bus cancellations are expected on Tuesday.

It is completely up to the school boards, bus companies, local authorities, and parents to decide what is best for their children. This is our best guess based on our forecast.
