Trader consensus on Polymarket heavily favors a high of 3°C in Toronto on March 23 (32.5% implied probability), driven by the latest Environment Canada guidance and ensemble model outputs from GFS and ECMWF, which project cloudy conditions with light snow showers capping daytime highs amid a lingering upper-level trough. This cool signal reflects persistent cold air advection from a polar vortex remnant, overriding seasonal norms where March 23 averages hover around 6°C historically. Warmer outcomes (4°C or 5°C+) gain traction (17.5% each) if ridging amplifies ahead of an incoming frontal system, while sub-2°C scenarios (<16% combined) hinge on intensified northerly flow; high uncertainty stems from 12-24 hour forecast divergence and microscale urban heat effects at key stations like Pearson Airport. Watch 00Z model runs for shifts.

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.
