Latest ensemble forecasts from Environment Canada highlight a strengthening southwesterly flow advecting warm, moist air from the Midwest beneath a building ridge, positioning Toronto for a daytime high near 29–30 °C on May 18. Diurnal heating under mostly clear skies supports this range, yet afternoon convection and Lake Ontario’s lake-breeze circulation introduce 1–2 °C of downward variability if clouds develop earlier than modeled. With market-implied probabilities tightly clustered between 29 °C and 32 °C or higher, traders weigh these competing factors—ridge-driven warmth versus boundary-layer moisture and timing of any showers—while awaiting the next model runs for clearer resolution of peak temperature.
