Snow Day (Bus Cancellation) Outlook for Tuesday, November 23, 2021

Lake effect snow and localized squalls will continue around the Lake Huron and Georgian Bay shoreline overnight into Tuesday. However, the squalls are expected to weaken somewhat by the early morning so conditions at the time won’t be as bad as compared to earlier in the night. Despite that, the significant accumulation between 15-30cm still to come by the morning will likely result in some school bus cancellations through the affected area as roads will still be snow covered along with localized blowing snow.

The highest probability ranges from 50-75% which includes Simcoe County and portions of Grey-Bruce counties directly near Lake Huron and Georgian Bay. Some lake effect snow will continue to linger through the morning hours in the regions we've given the 75% chance of a snow day. Although it might not be enough as this region appears to be more stringent when calling a snow day even with a snow squall warning from Environment Canada in effect. The further away from the shorelines, the lower the chance of a snow day as this will be mainly contained to the traditional snowbelt.

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.
