Environment Canada's latest forecast, issued Friday afternoon for Toronto Pearson International Airport—the market's resolution station—projects a daytime high of 8°C on April 12 amid mainly cloudy skies and periods of showers starting in the morning, anchoring trader sentiment around 7–9°C outcomes with implied probabilities tightly clustered at 19–22%. This reflects a recent downward shift from earlier projections near 13–14°C, driven by an advancing frontal system introducing cool northwest winds, persistent cloud cover, and precipitation that caps daytime heating despite seasonal norms of 11–12°C highs. Ensemble models show variability in rain timing and intensity, which could nudge the peak toward 7°C under heavier overcast or 9–10°C with earlier clearing; watch for Saturday evening updates and hourly observations as resolution nears.
