Recent official forecasts from Environment Canada and supporting model guidance indicate a sunny Saturday with a daytime high near 23°C in Toronto, driven by high pressure, light northerly flow, and minimal cloud cover that limits daytime heating. This consensus aligns with the market's strong preference for 23°C, as late-September climatology in the region typically features highs of 20–22°C under similar synoptic patterns, while warmer 24°C outcomes remain plausible if afternoon mixing exceeds current projections. Surface observations and ensemble runs show low precipitation risk and stable conditions through the 26th, with final temperature verification expected from Pearson Airport data shortly after sunset.
