Official forecasts from Environment Canada project a 17°C high for Toronto on October 6 under sunny conditions with light westerly winds, following a cooler air mass shift after recent showers. This aligns with the seasonal average high of 17.1°C and supports the market's leading implied probabilities for 16°C (47%) and 17°C (26.5%). Model consensus from GFS runs shows minimal warming potential amid stable high pressure, though minor revisions in steering patterns or cloud cover could adjust the peak by 1–2°C. Traders appear to weigh these near-term dynamical guidance updates heavily ahead of resolution.
