**Current ensemble forecasts from Environment Canada and global models place Toronto’s July 6 maximum in the 25–26 °C range**, keeping those two outcomes neck-and-neck at 26.5 % and 29 %. A modest upper-level ridge lingers but is offset by Lake Ontario’s cooling lake-breeze circulation, which typically caps downtown highs 1–2 °C below inland values when winds turn onshore by afternoon. Scattered cloud cover and a slight chance of showers could further suppress the peak by limiting insolation, while any earlier clearing or lighter winds would allow a quick climb to 27 °C. Historical early-July variability around the seasonal mean of ~26–28 °C adds to the tight spread; updated model runs tonight and tomorrow morning will determine whether the market tilts toward the lower or higher of the two leading buckets before resolution.
