Forecast models from Environment Canada and global ensembles project Toronto’s overnight low on September 17 near 15–17 °C under mostly cloudy skies and light northerly flow, with Lake Ontario’s moderating influence limiting radiative cooling. Trader sentiment remains evenly split between an 11 °C-or-below outcome and 21 °C-or-higher because model runs diverge on the timing of any clearing and the strength of boundary-layer mixing; weaker winds and reduced cloud cover could allow temperatures to dip further, while persistent cloud and onshore flow would hold the minimum closer to seasonal norms of roughly 13–14 °C. Official hourly observations from Pearson Airport will determine the precise minimum for 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.
