**Forecast divergence between official guidance and private models is the main driver of trader positioning around 19–20°C lows for Toronto on September 9.** Environment Canada’s latest bulletin calls for showers during the day (high 24°C) followed by a 60% chance of overnight showers and a low of 15°C, consistent with cooler air advection behind a passing system. In contrast, several GFS-based and international services project overnight minima near 19–20°C (67–68°F) amid persistent cloud cover and lighter winds that limit radiational cooling. Historical September 9 averages near 15°C provide context, yet current model spread—particularly on timing and intensity of showers—keeps probabilities clustered between 19°C (36%) and 20°C (30%), with 24°C+ at 27.5% reflecting residual uncertainty ahead of updated model runs and the next Environment Canada issuance.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 9 Sep '26.
The resolution source for this market will be information from NOAA, specifically the lowest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=cyyz
If NOAA data for the observation date is unavailable by 11:59 PM ET on the day following the observation date, the Weather Underground Daily Observations table will be used as the resolution source.
In the event that there is no data for the observation date by 11:59 PM ET on the day following the observation date, this market will resolve to the lowest bracket.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market will resolve once the first data point for the following date has been published on the resolution source, or by 11:59 PM ET on the day following the observation date, whichever comes first.
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.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.**Forecast divergence between official guidance and private models is the main driver of trader positioning around 19–20°C lows for Toronto on September 9.** Environment Canada’s latest bulletin calls for showers during the day (high 24°C) followed by a 60% chance of overnight showers and a low of 15°C, consistent with cooler air advection behind a passing system.
