Forecast consensus from recent model runs points to a mild overnight minimum near 19°C in Toronto on September 9, driven by persistent southerly flow advecting warm, humid air ahead of a slow-moving frontal system and associated thunderstorms. Elevated dew points near 18–20°C and widespread cloud cover are limiting radiative cooling, while light winds reduce mixing that could otherwise drop temperatures further. Historical September climatology shows typical lows around 14–15°C, making this setup notably warmer. Traders appear to weigh GFS and similar guidance showing the daily minimum falling between 18–20°C, with minor model spread in storm timing and wind shifts creating the tight clustering around those outcomes. Environment Canada updates and next model cycles will refine the exact threshold.

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.
