Environment Canada's latest forecast, issued April 4, pegs Toronto's April 6 high temperature at around 5-6°C under mixed sun and cloud with a 30% chance of flurries or showers, driving trader consensus where 6°C holds a 27.5% implied probability ahead of 5°C at 20.5% and 7°C at 17.5%. This below-normal outlook—early April climatological highs average 8°C—stems from a persistent cool upper-air trough over southern Ontario, limiting diurnal heating despite light winds, with GFS and ECMWF ensembles converging on similar maxima but diverging slightly on cloud cover evolution. Key differentiators include afternoon clearing potential versus persistent overcast, which could nudge outcomes by 1-2°C; monitor tomorrow's 12z model runs and Pearson Airport observations for refinements ahead of resolution based on official hourly maxima.
