Environment Canada's latest forecast, issued at 5:00 AM EDT on April 1, projects a daytime high of 23°C for Toronto on April 3 under cloudy skies with a 60% chance of showers, driving the market-implied 98.6% probability for 9°C or higher as traders aggregate this strong signal from real-money bets. Ensemble guidance from GFS and ECMWF models reinforces this outlook, showing a warm air mass over southern Ontario amid typical early April variability where highs average 10–12°C but warm spells are common. This near-unanimous trader consensus reflects high confidence close to resolution, though realistic challenges include an unforeseen cold frontal passage or prolonged overcast conditions capping temperatures below 9°C—scenarios with low likelihood per current guidance. Updated forecasts tomorrow morning could refine details ahead of measurement at Toronto Pearson International Airport.
