Snow Day (Bus Cancellation) Outlook for Monday, November 23, 2020

A snowstorm that has brought widespread snowfall accumulation between 10-20cm throughout Southern Ontario during the day on Sunday is expected to continue to affect parts of Eastern Ontario into the overnight hours and Monday morning. This will result in a messy morning commute in Eastern Ontario particularly around the Pembroke, Renfrew and Ottawa area where the precipitation will stay mainly snow with some freezing rain mixed in after midnight.

A messy commute means there is a good chance of school bus cancellations in the hardest-hit regions. The probability ranges from 50-75% through the Ottawa Valley and away from Lake Ontario. Those closer to Lake Ontario like Kingston has a slightly lower chance because lots of rain is expected to mix in overnight which will likely reduce the accumulation to below the threshold needed for any cancellations. Now while Southwestern Ontario (London, K/W etc.) and the GTA have seen significant snowfall accumulation, we expect there to be plenty of time for road crews to clean up the roads in time for the morning and precipitation is already beginning to taper off this evening. We’ve still given these regions a 5-10% chance of a snow day but it’s fairly unlikely unless local road conditions unrelated to the weather cause some cancellations.

If there are any cancellations tomorrow morning, you can be sure we’ll be up bright and early beginning at 6 AM with our bus cancellations live blog to keep you updated.


Disclaimer: Instant Weather has zero authority when it comes to bus and school closures. It is completely up to the school boards, bus companies, and local authorities as well as being up to parents to decide what is best for their children. This is simply our best guess based on our forecast. Also note that due to the current pandemic, some school boards have changed their policies on school bus cancellations. Some will continue the school day in a virtual format should there be school bus cancellations - check with your local board for more details.
