Traders heavily favor 12°C or below (96.4% implied probability) for Toronto's highest temperature on March 22, driven by Environment Canada's official forecast projecting a daytime high of only 4-7°C amid entrenched Arctic air masses and northerly winds. This consensus aligns with ensemble outputs from ECMWF and GFS models, which converge on temperatures 3-5°C below the seasonal March average of 7°C, corroborated by recent observations of overnight lows near 0°C. Historical data shows Toronto's March highs rarely exceed 12°C outside mild spells, with current 500 mb charts indicating stable cool patterns. Realistic challenges include an abrupt ridge amplifying southerly advection for a 5-10°C surge—possible in ~5-10% of similar setups per model verification stats—or localized urban heat effects, though low odds given overcast skies.
