Reading the answer

"Yes" means at least one hour in the next 24 has a 40% chance of rain or a forecast of 0.2 mm or more. Hourly chances come from Environment Canada's forecast for the nearest forecast point, and the 2-hour nowcast from a 15-minute precipitation model.

A percentage is the chance that measurable rain falls at a given spot, not the share of the day it rains. Showers in summer can stay very local, so a 40% afternoon may stay dry across town.
