Recent forecast models from Environment Canada and global ensembles indicate a minimum temperature near 14°C on August 24 in Toronto, driven by persistent cloud cover, light showers, and moderate westerly winds that limit overnight radiative cooling under a post-frontal air mass. This setup creates narrow uncertainty around the 13–16°C range, with minor model spreads in timing of clearing and dew point depression explaining the near-even trader probabilities clustered near 12–14°C thresholds. Historical August minima average 15–16°C, but the current pattern aligns with cooler analogs featuring onshore flow. Updated NWS and Canadian model runs tonight will refine the exact low before market resolution.
