Trader consensus on Polymarket strongly favors a high of 3°C or higher in Toronto on March 27 (68.5% implied probability), driven by Environment Canada’s latest forecast projecting a daytime maximum near 4°C under partly cloudy skies with light winds. This aligns with ECMWF and GFS ensemble models showing a high-pressure ridge stabilizing over southern Ontario, following recent observations of rebounding temperatures from sub-zero lows earlier in the week. Historical March climatology supports mild outliers, with average highs around 5°C, though short-range model divergences introduce uncertainty for precise bins like 2°C (12.5%). Traders eye hourly updates from Pearson Airport observations for final resolution.
