Trader sentiment clusters tightly around 1-3°C highs for Toronto on March 23, driven by ensemble forecasts from Environment Canada, ECMWF, and GFS models averaging 2°C amid a late-winter cold pool. Leading 2°C and 3°C odds (23.5% each) reflect a moderating southerly flow battling Arctic air advection, with subtle differences hinging on the exact timing of a low-pressure trough—earlier arrival caps at 1-2°C (19.5% and 18.5%), while delay allows 4-5°C spikes (10-18.5%). Historical March 23 data shows mean highs near 4°C but high variability (±4°C standard deviation), amplifying uncertainty as 00Z updates loom. Lower tails (-1°C or below) fade on gradual warm-up signals.
