**Current forecast models from Environment Canada and supporting guidance indicate the overnight low for the night of October 8–9 will reach 6–8 °C under clearing skies and northwest flow, with daytime highs near 18 °C on October 9.** This pattern reflects typical early-autumn radiative cooling beneath building high pressure after a period of showers, with minimal cloud cover allowing efficient heat loss overnight. Historical October minima in Toronto average near 9 °C, but the current setup favors readings several degrees below that baseline. Trader consensus reflected in the elevated 46.5 % implied probability for 2 °C or below, alongside the cluster near 6–8 °C outcomes, aligns with the latest model consensus on the precise minimum threshold while acknowledging residual uncertainty in boundary-layer mixing and exact wind speeds through the overnight period. Updated model runs and official Environment Canada briefings expected later today represent the next key data points that could refine these market-implied odds.
