Recent forecast models from Environment Canada and global ensembles indicate clear skies and northwest flow over Toronto on October 6, 2026, promoting strong nocturnal radiative cooling after a frontal passage, with overnight lows projected in the 5–8 °C range under light winds. This aligns with the market’s tight clustering of implied probabilities around 3–9 °C outcomes (each ~33–34 %), while the 48.5 % chance assigned to 10 °C or higher reflects residual model spread and potential for slightly milder boundary-layer mixing. Historical climatology places the average October 6 low near 9.7 °C, underscoring how the current cool-air advection has shifted expectations downward. Updated model runs and surface observations over the next 48 hours will be the key catalysts for any probability adjustments.
