Environment and Climate Change Canada's latest forecast, issued late April 30, projects a daytime high of 11°C in Toronto on May 3 under increasing cloudiness following recent frost advisories and cool northerly flows, anchoring trader consensus near this mark while elevating 13°C to a slim 55% implied probability amid ensemble model spreads from GEM, GFS, and ECMWF showing potential for 10–14°C based on cloud timing and boundary-layer mixing. Persistent upper-level troughing over the Great Lakes suppresses typical early-May highs averaging 14–16°C, but slight diurnal warming or delayed overcast could tip outcomes higher; lower extremes remain unlikely absent renewed cold snaps. New observational data and afternoon updates from ECCC on May 1–2 will clarify before resolution at Pearson Airport.
