Environment and Climate Change Canada's latest forecast for Toronto Pearson International Airport, the market's resolution station, projects a May 14 high of 13°C under mostly cloudy skies with a 40% chance of showers and northwest winds gusting to 40 km/h, reflecting cool air advection from a recent frontal passage that capped May 13's high below earlier expectations around 10°C by late afternoon. Trader sentiment clusters tightly around 11°C (30.5%) and 12°C (27.5%) implied probabilities, diverging slightly lower due to persistent low-level clouds limiting insolation and potential shower cooling, with model ensembles showing spread in afternoon clearing and boundary layer mixing. Key differentiators include cloud fraction evolution—breaks could push toward 13-14°C—and precip timing, per hourly updates; new GEM regional model runs expected overnight may refine odds ahead of resolution. Climatological May highs average 18°C, underscoring the current cool anomaly.
