Recent official forecasts from Environment Canada and other models indicate a daily minimum near 14–15°C for Toronto on September 12 under a mix of sun and cloud with a 40% chance of showers, driven by southerly flow ahead of an approaching frontal system. This places the expected low well above 10°C while remaining below 20°C, creating the near-even split in market-implied odds between those broad outcomes. Key differentiating factors include the precise timing of any shower-cooled air masses, overnight wind speeds that could enhance or suppress radiational cooling, and minor model disagreements on boundary-layer moisture. Historical September climatology shows typical overnight lows in the low teens, so traders are weighing whether current warm advection will hold or if brief clearing allows faster temperature drops. Updated model runs and Environment Canada briefings over the next 48 hours will likely resolve the narrow range around 13–15°C.

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.
