Environment Canada's latest 7-day forecast projects a daytime high near 10°C for Toronto on April 3 under cloudy skies with a 60% chance of showers, driving trader consensus to a 59.5% implied probability for 9°C or higher as the leading outcome. This positioning reflects ensemble guidance from GFS, ECMWF, and GEM models indicating mild early-spring conditions above the climatological average high of about 9°C, supported by a warming pattern across southern Ontario as noted in recent long-range outlooks. Lower probabilities for sub-8°C outcomes stem from historical precedents where April 3 highs rarely fall below 5°C, amid transitioning seasonal flows. Inherent forecast uncertainty persists due to volatile spring weather; watch for Environment Canada updates every 12 hours as proximity to the date sharpens model accuracy.
