Trader sentiment for Toronto's August 23 lowest temperature reflects uncertainty in overnight cooling at Pearson Airport amid a passing weather system with thunderstorms and variable cloud cover. Forecasts indicate daytime highs near 21–25°C, but evening and pre-dawn conditions depend on wind speed, precipitation timing, and radiative cooling rates under partly to mostly cloudy skies, which can limit temperature drops compared to clear conditions. Official guidance points to lows around 13–19°C, with model runs showing modest spread tied to the strength of any cooler air advection and urban versus airport microclimate differences. The near-even split between sub-10°C and 16°C outcomes captures this variability, as stronger storm outflows or clearer breaks could push readings lower while persistent moisture and mixing hold them near seasonal norms of 15–17°C. Updated Environment Canada and NOAA observations through the evening will clarify resolution.
