Trader consensus heavily favors a high of 8°C or below in Toronto on March 26 at 54.5% implied probability, driven by Environment Canada's latest forecast models projecting a daytime maximum around 5-7°C amid persistent northerly winds and cloud cover from a recent cold front. Historical late-March averages hover near 6°C, aligning with these cool odds, while 9°C at 28.5% reflects slight upside from potential afternoon clearing. Ensemble models like GFS and ECMWF show low confidence in warmer outliers above 10°C due to stable high-pressure influence, with no major updates expected until tomorrow's 12Z runs potentially refining these market-implied odds further.
