Environment Canada's latest hourly forecast for Toronto Pearson International Airport, the market's resolution station, projects a high of 20°C on April 18 around 5 PM EDT, following overnight showers and morning clouds giving way to mainly sunny afternoon skies with low 10% precipitation odds. This aligns with trader consensus favoring 18–20°C outcomes at over 93% implied probability combined, driven by a mild spring pattern—yesterday's 21°C high and above-normal temperatures amid weak frontal influences. Differentiating factors include potential persistent cloud cover or delayed clearing near Lake Ontario, which could suppress peaks to 18–19°C per some model ensembles like GFS variants, versus full insolation enabling 20°C. Final observations will confirm amid inherent short-range forecast uncertainty.
