**Persistent cloud cover, showers, and high humidity are limiting overnight radiative cooling in Toronto, keeping the daily minimum temperature tightly clustered around 17–19°C on August 30, 2026.** Official forecasts from Environment Canada and other models project an overnight low near 19°C under mostly cloudy skies with a 40% chance of showers and light southwest winds, while some runs show slightly more clearing or modest wind shifts that could allow the temperature to dip to 17–18°C by dawn. These conditions align with the closely matched market-implied odds (19°C at 43.5%, 17°C and 18°C at 42.5%). High dew points near 17–18°C reflect abundant atmospheric moisture that reduces the temperature drop through latent heat release and suppressed longwave radiation loss. Historical August 30 averages (high ~25°C, low ~16°C) are exceeded due to the current warm, humid airmass without a strong cold front or clear skies to enhance cooling. Minor model differences in cloud persistence or boundary-layer mixing explain the narrow spread among leading outcomes, with very low probabilities assigned to extremes below 16°C or above 20°C given the stable pattern. Updated overnight observations and any late-day clearing will be the key near-term drivers for final 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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
