Environment Canada's latest forecast for Toronto on April 16 calls for a high of 18°C under cloudy skies with a 60% chance of showers, capping temperatures after today's warmer 23°C peak amid ongoing heavy rain and thunderstorms. However, GFS and ECMWF model ensembles indicate a slight spread toward 19–20°C peaks if cloud cover thins or precipitation eases, reflecting trader sentiment split nearly evenly between these outcomes at around 29% and 28% implied probabilities. Key differentiators include incoming low-pressure systems enhancing shower risk and suppressing insolation, versus potential ridging allowing brief warm-air advection; historical mid-April variability at Toronto Pearson Airport adds uncertainty. Updated hourly guidance expected overnight could sharpen resolution before observations begin.
