Latest forecast models from sources like Environment Canada and global ensembles point to a Toronto minimum around 16–17°C on September 17 under northerly winds, partly cloudy skies, and modest moisture, keeping the night from cooling sharply. This aligns with the market’s clustering around 15–17°C outcomes while the elevated 38.5% implied probability on 21°C or higher reflects recent above-average September warmth (+3.5°C monthly departure) and potential model spread on cloud cover or boundary-layer mixing that could limit overnight drops. Historical September 17 lows average 13.5°C, so current conditions represent a milder-than-normal setup with limited further cooling expected before dawn. Updated model runs and official observations tomorrow morning will refine these probabilities.

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.
