Traders are pricing in a 98.2% chance of Toronto's highest temperature on March 22 reaching 12°C or below, driven by Environment Canada's official forecast projecting a midday high near 6°C amid persistent northerly winds and a deep trough over eastern North America. This consensus aligns with March climatology—historical maxima average 7°C, with the 90th percentile rarely topping 11°C—and convergent model runs from GEM and GFS ensembles showing radiative cooling and light snow risks reinforcing cool conditions. A realistic challenge would require an abrupt ridge amplification to funnel unseasonal southerly flow, but current jet stream dynamics and soil moisture deficits make such a warm anomaly improbable without prior signals.

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.
