Forecast models from Environment Canada and private sources currently converge on a Toronto high near 26–27 °C for July 20, driving the market’s leading probabilities for those outcomes. Key variables include daytime cloud cover that could limit solar heating, boundary-layer moisture influencing the strength of any lake breeze off Lake Ontario, and minor model spread in 850-hPa temperatures. Historical July averages hover near 26 °C, so modest deviations from guidance—such as clearer skies or stronger southerly flow—could shift the peak by 1–2 °C either way. Updated model runs and official forecasts issued overnight will provide the next clear signals for traders.
