Current forecasts from Environment Canada and major models indicate overnight lows near 14°C for Toronto on August 24 under persistent cloud cover, westerly winds of 15–20 km/h, and scattered showers that limit radiative cooling. Trader sentiment reflects this baseline, with the 47% implied probability on 9°C or below and 44.5% on 12°C capturing residual uncertainty in exact minimum timing and any brief clear intervals that could allow greater heat loss. Westerly flow advecting cooler maritime air, combined with high humidity and dew points around 12–13°C, keeps the distribution tightly clustered around these thresholds rather than extremes. Updated model runs and surface observations tonight will clarify whether conditions trend toward the lower or mid-teens.
