Periods of light snow are expected tonight into Tuesday across Southern Ontario.

Snowfall amounts are expected to remain fairly minor, with most areas picking up less than 5 cm by the time the snow tapers off late Tuesday. Because of this, conditions are not expected to deteriorate enough to reach the threshold that typically leads to school bus cancellations.

That said, there is a very small window for isolated impacts in a few regions near the lakes. We have assigned a very low chance to areas covered by the Bluewater District School Board, the Avon Maitland District School Board and the Near North District School Board. In these regions, snow is expected to be heaviest close to the time when school boards are making their morning decisions.

In addition, slightly stronger winds near the Lake Huron and Georgian Bay shorelines could lead to some localized blowing snow, briefly reducing visibility on exposed rural routes. Even so, snowfall rates and overall accumulation should remain limited, making cancellations unlikely.

Because of these marginal factors, we have gone with a 5 percent chance for these regions. This is very much a “don’t count on it” scenario, and the expectation remains that buses will run as normal.

Everywhere else across Southern Ontario is not expected to see any chance of a snow day on Tuesday. Snowfall should be light, roads should remain manageable, and no significant travel disruptions are anticipated.

So despite a bit of light snow in the forecast, Tuesday is shaping up to be a routine school day across the province. In other words, homework is still on the schedule!
