Persistent showers and a cooler westerly flow are suppressing daytime heating, positioning 21°C as the market leader at 38.5% implied probability. Environment Canada’s latest forecast calls for showers throughout August 23 with a daytime high of 21°C, consistent with model consensus showing an incoming air mass that limits solar insolation and promotes evaporative cooling. This setup deviates from the 1991–2020 climatological average high near 25.5°C, keeping probabilities for 22°C (26.5%) and 20°C (22.5%) as secondary outcomes while sharply discounting 23°C or warmer. Updated model runs and the official high-temperature verification at Pearson Airport will determine final resolution as the event unfolds.
