Current forecast models from Environment Canada and other agencies point to an overnight low near 15°C for Toronto on September 6 under partly cloudy skies and light northeasterly winds, keeping the minimum temperature in a narrow range that aligns with the closely matched market-implied odds around 15°C, 16°C, and 17°C. Stable high pressure and seasonal lake moderation limit cooling potential compared to historical averages of 15.5°C, while minor model spread in cloud cover and boundary-layer mixing creates uncertainty that supports the dispersed probabilities across the 10–20°C bins. Traders will monitor the final evening model runs and real-time observations through tonight for any last adjustments before resolution.

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.
