Recent ensemble forecasts from global models, including GFS runs, indicate Toronto's October 14 high will likely settle near 17–18 °C under a post-frontal northwest flow and widespread cloud cover that limits diurnal warming. A cooler, drier air mass advected behind Tuesday's warm, showery southwest flow has stabilized conditions, with surface high pressure expected to suppress convective activity and keep afternoon temperatures close to the 15 °C climatological normal. Minor model disagreements center on the precise timing of any partial clearing and boundary-layer mixing, which could shift the daily maximum by 1–2 °C. Traders are therefore weighting outcomes around the forecast consensus while assigning notable probability to both cooler and warmer tails given the two-day lead time and typical short-range variability in autumn thermal profiles.
