Official forecasts from Environment Canada project a sunny Friday with a high near 22°C followed by overnight lows around 14°C under increasing cloud cover and light northerly winds, aligning with the clustered market probabilities near that threshold. Recent model consensus supports moderate radiative cooling overnight without significant cold-air advection, though minor variations in cloud timing or wind speed could shift the minimum by 1–2°C. This setup contrasts with historical September 18 averages of roughly 13°C lows, leaving room for traders to weigh ensemble spread against the current high-pressure influence. Updated Environment Canada guidance and next model runs over the next 24 hours will likely refine the exact minimum ahead of market 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.
