Current ensemble forecasts from Environment Canada and the National Weather Service indicate Toronto’s May 17 high will most likely reach 23–25 °C, with 24 °C holding the narrowest edge among traders. A mild southerly flow is expected to advect warmer air northward ahead of a weak frontal boundary, while partial cloud cover and light winds limit additional daytime heating. Ensemble spread remains tight because model runs show only modest differences in boundary-layer moisture and solar insolation. Historical May climatology places the long-term average near 20 °C, so the current setup represents a modest positive anomaly. Overnight model updates and any last-minute changes in cloud timing will be the next key data points for refining the outcome before official observations determine market resolution.
