Environment Canada's forecast issued early April 11 pegs Toronto Pearson International Airport's high at 8°C on April 12, with mainly cloudy skies, periods of rain from morning to late afternoon, and east winds gusting to 40 km/h—cooler onshore flow suppressing temperatures via increased cloud cover and evaporative cooling. Trader-implied odds cluster tightly around 8–10°C (67% combined probability), reflecting model consensus on a passing low-pressure system but uncertainty in rain timing and intensity; drier scenarios or quicker clearing could push toward 10°C, while heavier precip favors 7°C or lower. Today's clearing to a 10°C high sets a mild baseline, with afternoon updates and hourly observations key to refining trajectories before resolution.
