Regions northeast of Georgian Bay are expected to see another round of snow squalls developing Friday morning and continuing throughout the day. These bands may intensify at times, creating reduced visibility and rapid snowfall accumulation.

Environment Canada has issued a snow squall watch for the area, noting the potential for 20 to 40 cm of snow. Given that setup, there is a reasonable chance that the Near North District School Board will choose to cancel buses in the hardest hit regions.

The highest likelihood is in the Parry Sound zone, which sits closest to where the squalls are expected to come ashore. We have assigned this area a 75 percent chance of cancellations. The remainder of Near North, including East Parry Sound and North Bay, is sitting at 50 percent as it is still unclear how far inland the strongest bands will extend.

We have also included a 25 percent chance for the Rainbow District School Board, focused mainly on Manitoulin Island, where the snow squall watch is also in effect. It is unlikely that the board would cancel across the entire district, so those in Greater Sudbury should expect buses to run as usual.

Elsewhere across Southern Ontario, no significant weather impacts are expected. This leaves the chances of a snow day in the low to very low range for most regions, so it may be a good idea to plan on doing your homework.

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.
