Thus, this is the level of precision that will be used when resolving the market. Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.Environment Canada's forecast issued Sunday evening projects a high of 16°C for Toronto on March 30 under mainly sunny skies early, with southwest winds gusting to 40 km/h promoting warm air advection well above the late-March normal of 8°C, anchoring trader consensus at 96% implied odds for 15°C or higher. Yesterday's high reached only 10°C amid cloudy conditions at Pearson International Airport, but today's setup features stronger solar insolation and a favorable ridge aloft, aligning with recent spring-like surges including early-month records near 18°C. Realistic challenges include the forecast increasing cloudiness suppressing afternoon heating or an abrupt wind shift, though model ensembles show tight agreement; hourly observations will clarify resolution by sunset around 19:40 EDT.
