Environment Canada’s latest forecast, updated April 14 afternoon, projects a daytime high of 21°C for Toronto under cloudy conditions with 60% shower chances and early thunderstorm risk, driving trader consensus toward 20°C at 36.5% implied probability as clouds and precipitation may suppress peak heating by 1–2°C despite southerly winds advecting mild air masses. GFS, ECMWF, and GEM ensemble models show a tight 19–21°C cluster with modest spread from instability timing, well above the April climatological average of ~12°C at Toronto Pearson International Airport (CYYZ), the market’s resolution station via Wunderground. Overnight lows near 13°C set a warm baseline, but diurnal observations today will refine outcomes as solar heating interacts with prefrontal moisture.
