Recent severe thunderstorms and an advancing cold front across southern Ontario on September 2-3 are driving cooler post-frontal air into the region, positioning Toronto for a mostly partly cloudy September 4 with northwest winds limiting daytime heating. Official forecasts from Environment Canada and numerical models converge on afternoon highs near 24-26°C, consistent with the historical average of 24.1°C for the date, though slight differences in frontal timing, residual moisture, and cloud cover create spread among ensemble runs. Market-implied odds reflect this genuine forecast uncertainty, with traders assigning the highest probabilities to 25-26°C outcomes while discounting extremes given the stabilizing high-pressure influence expected behind the front. Updated model guidance and official briefings over the next 48 hours will likely refine these probabilities ahead of resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
