Environment Canada's latest forecast for Toronto Pearson International Airport, the probable resolution source, projects a daytime high of 7°C on April 1 under cloudy skies with northwest winds gusting to 40 km/h shifting northeast, yet traders overwhelmingly back 10°C at 92% implied probability, driven by prior 24-hour model consensus (e.g., 9°C peaks in recent runs) and historical early-April averages near 10°C amid a cool, stable air mass post-recent heavy rains. Current 7 a.m. observations show 2°C with mostly cloudy conditions and 84% humidity, reinforcing limited warming potential. Realistic challenges include unexpected afternoon cloud breaks enabling solar heating to 11°C+ or stronger onshore flow capping below 10°C; hourly updates from Environment Canada will clarify as the day progresses.
