Trader consensus heavily favors a Toronto high of 3°C (87% implied probability) due to Environment Canada's latest forecast, which pins the maximum at 3°C amid cloudy skies and possible flurries from a persistent cold air mass over the Great Lakes region. Shortwave model ensembles from ECMWF and GFS align on this outcome, showing limited solar insolation and northerly winds capping warming, with morning temperatures starting near 0°C. Recent hourly observations confirm subdued diurnal heating, while 4°C (8.5%) reflects minor upside from urban heat island effects; warmer outcomes above 5°C remain improbable given seasonal climatology (March average high ~6°C) but cooler anomalies this year. Updated guidance expected by evening could shift minor probabilities.
