Powered by NOAA / National Weather ServiceSt Thomas More School is a middle school in Mississauga, Ontario, part of Dufferin-Peel Catholic District School Board. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.
Closure decisions for St Thomas More School are almost always made at the district level. If Dufferin-Peel Catholic District School Board closes, this school closes with it — so the district-wide forecast is usually the number that matters (see the Dufferin-Peel Catholic District School Board forecast).
Ontario averages about 150 cm of snow per year. Ontario school boards make independent closure decisions. Northern boards have higher thresholds than southern Ontario. Toronto rarely closes, while Ottawa, Sudbury, and Thunder Bay close more frequently for heavy snow and extreme cold.
We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.
This is an independent forecast, not an official announcement. Confirm any closure with Dufferin-Peel Catholic District School Board before acting on it.
