Ensemble weather models from Environment Canada and the ECMWF indicate a high near 3°C for Toronto on March 27, propelled by a mild southerly flow displacing recent Arctic air, fueling the 72% market-implied probability for 3°C or higher. Official forecasts project daytime maxes of 2-4°C amid partly cloudy skies and light winds, aligning with historical late-March averages of 5°C but tempered by lingering winter patterns. Trader sentiment shifted upward after yesterday's GFS update raising temps by 1-2°C from prior runs, while lower outcomes like 2°C (16.5%) reflect ensemble spread and potential cloud cover. Monitor hourly observations from Pearson Airport, as resolution hinges on the official daily maximum.
