Tight clustering of market-implied probabilities around 3-5°C stems from consensus forecasts from Environment Canada and ECMWF ensembles, projecting Toronto's March 25 high near 4°C under a deepening upper-level trough ushering cooler mid-latitude air. Recent 00Z model runs show slight divergence, with GFS leaning 1°C warmer via enhanced ridging, while Canadian GEM emphasizes cold advection from lingering Arctic outflows, amplifying uncertainty in boundary-layer stability. Differentiating factors include urban heat island amplification (potentially +1-2°C over rural Pearson Airport readings) and lake-enhanced cloud cover from Lake Ontario, historically capping 30% of similar March days below 3°C versus trader-favored mild recovery. Upcoming 12Z updates could shift odds if southerly flow strengthens.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Toronto Pearson Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/ca/mississauga/CYYZ.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). 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.
