**Northeast winds advecting cooler, drier air from higher latitudes are the main driver behind Toronto's expected overnight low near 7–10 °C on 21 September.** Official guidance from Environment Canada and consistent GFS/ECMWF runs show partly to mostly cloudy skies with sustained 15–20 km/h northeast flow, limiting radiational cooling while preventing extreme drops; dew points falling into the 4–6 °C range support this narrow band. The near-even 49 % market-implied odds on both ≤4 °C and ≥14 °C reflect residual model spread in boundary-layer mixing and exact cloud cover timing, while the 20–23 % probabilities clustered around 7–12 °C align with the consensus forecast. Historical early-fall analogs and current 500 hPa pattern indicate limited potential for either a sharp cold surge or rapid warming before dawn.

This market will resolve to the temperature range that contains the lowest temperature recorded by NOAA at the Toronto Pearson Intl Airport Station in degrees Celsius on 21 Sep '26.
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.**Northeast winds advecting cooler, drier air from higher latitudes are the main driver behind Toronto's expected overnight low near 7–10 °C on 21 September.** Official guidance from Environment Canada and consistent GFS/ECMWF runs show partly to mostly cloudy skies with sustained 15–20 km/h northeast flow, limiting radiational cooling while preventing extreme drops; dew points falling into the 4–6 °C range support this narrow band.
