Latest ensemble forecasts from Environment Canada and global models like ECMWF and GFS project Toronto's highest temperature on March 24 around 4-6°C, driving the tight clustering of market odds with 6°C or higher at 35%, 5°C at 28%, and 4°C at 24.5%. This mild outlook stems from a building high-pressure ridge aloft, promoting downslope warming and light southerly winds, contrasting historical March 24 averages near 3-5°C. Trader sentiment differentiates leaders via model spread: ECMWF leans warmer with clearer skies boosting peaks to 6°C+, while GFS shows cloudier scenarios capping at 4-5°C; colder outliers below 2°C reflect low-probability cold frontal intrusions, per verified guidance. Uncertainty persists in timing of any late-day clearing.
