Environment Canada's latest forecast, issued April 30, pegs Toronto's May 2 high at 10°C under a mix of sun and cloud, with near-freezing overnight lows signaling a persistent cool air mass from an upper-level trough over eastern North America. This aligns with trader consensus favoring 9–11°C outcomes, below the 16°C seasonal norm amid a sluggish spring pattern noted in long-range outlooks. Key differentiators include variable cloud cover impacting insolation, potential for 30–40% shower chances reducing peak heating, and slight model disagreements on boundary layer mixing—GFS and ECMWF ensembles show spreads of 2–3°C. Overnight model updates and hourly observations will sharpen resolution as the event nears.
