Environment Canada's latest forecast, issued late May 5, projects a high of 12°C in Toronto today amid mainly cloudy skies and 40% chance of showers, but persistent overcast conditions and a cool overnight low near 6°C have kept morning temperatures hovering at 7–9°C through noon, fueling trader consensus around 9–11°C outcomes. Light easterly winds and potential shower development limit solar insolation and diurnal heating, differentiating sub-10°C scenarios (requiring steady clouds or precip) from 11–12°C (needing partial clearing). Observed high yesterday reached 16°C under similar setup, yet hourly guidance signals subdued warming; updated afternoon forecasts from Environment Canada could shift odds as the day progresses. Normal early May high is 17°C.
