How the odds are worked out
The number comes from the next 24 hours of forecast for this town: snowfall, when it starts, the overnight low, freezing rain and gusts. What closes schools depends on the region, so the snow needed for high odds rises from about 4 cm on the BC coast to 15 cm in Ontario, Quebec and Atlantic Canada, 20 cm on the Prairies and 25 cm in the North. Freezing rain and extreme cold raise the odds on their own.
Boards usually announce bus cancellations and closures early in the morning, and their decision is the one that counts. Watch the radar and winter alerts the night before.
