Snow Day (Bus Cancellation) Outlook for Tuesday, December 7, 2021
/
Squalls have developed off the southeastern shoreline of Georgian Bay and are expected to continue overnight with intense snowfall accumulation and near-zero visibility. This will have a significant impact on the road conditions during the morning hours which will likely result in some school bus cancellations in the hardest-hit regions. We have given Simcoe and parts of Grey-Bruce counties a 75% chance of a snow day as bus cancellations are quite likely, however, this area has had a mixed record when it comes to cancelling buses due to snow squall activity so we can’t give them a 90% chance. Surrounding regions including the rest of Grey-Bruce counties into Huron-Perth and over into regions east of Lake Simcoe has a 50/50 chance as there is the potential for some whiteout conditions during the morning hours.
The probability of a snow day will quickly diminish the further you are from Georgian Bay since this is a very localized event. In the Parry Sound-Muskoka region, we’ve decided to go with a 25% chance because while we aren’t expecting much in terms of accumulation tonight, the squall activity will drift northward later in the day. We suspect Environment Canada may issue a snow squall watch for the area by morning which could prompt cancellations. In addition to this, road conditions are still quite icy and the very cold temperatures moving in overnight won’t help.
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.
