Environment Canada's latest forecast, issued late April 10, projects a high of 20°C in Toronto on April 13 under cloudy conditions with a 40 percent chance of showers, anchoring trader consensus around closely matched 19–21°C outcomes with implied probabilities near 20 percent each. This reflects ensemble model agreement on a mild southerly airflow bringing above-normal temperatures—well above the mid-April climatological average of 13°C—but with uncertainty from precipitation timing and cloud cover, potentially capping solar insolation and peak heating at 19°C or allowing boundary-layer mixing to push toward 21–22°C if showers clear early. The Weather Network concurs at 20°C with southwest winds gusting to 48 km/h. Watch for updated EC guidance on April 12, as new model runs could refine the tightly contested probabilities amid typical spring forecast divergence.
