Traders' overwhelming 94.5% consensus on a 3°C high in Toronto on March 21 stems from Environment Canada's official forecast, backed by converging ECMWF and GFS ensemble models showing a persistent Arctic air mass over southern Ontario amid weak pressure gradients. Verified observations from Pearson Airport confirm sub-freezing starts with daytime highs struggling amid cloudy skies and light winds, aligning with climatological March norms of 4-6°C but depressed by a -2°C anomaly from the current upper-level trough. This positioning holds unless a surprise shortwave ridge amplifies southerly flow, as seen in occasional model outliers, potentially lifting temps to 5°C+—a low-probability shift given 24-hour trend stability.
