Short-term forecasts for Toronto show considerable uncertainty for the September 5 minimum, with market odds clustered around 15–20 °C and notable probability on both warmer and cooler extremes. Key drivers include the position and strength of an approaching upper-level trough, expected cloud cover that modulates nocturnal radiative cooling, and boundary-layer wind speeds that influence mixing and urban heat retention. Ensemble model spreads reflect typical variability in early-September synoptic patterns over the Great Lakes, where lake-modified air masses and frontal timing can shift overnight lows by several degrees. Updated National Weather Service and Canadian Meteorological Centre runs, plus any new satellite or radiosonde data, will likely tighten the range before 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.
