Recent forecasts from Environment Canada highlight a strengthening southwesterly flow advecting warmer air into southern Ontario, combined with mostly sunny skies that favor enhanced daytime heating on May 17. These conditions have shifted model consensus toward a peak temperature at or above 27°C at Toronto Pearson International Airport, the official resolution station, elevating the market-implied probability for that bin to 71%. Historical May climatology shows typical highs near 18–20°C, making the current anomaly notable and sensitive to any late adjustments in cloud cover or wind shifts. Updated model runs expected later today will further refine whether the high exceeds the 27°C threshold or settles closer to 26°C.
