**Stable high-pressure conditions and clear skies are driving the tight clustering of market-implied probabilities around 21–24°C lows for Chongqing on September 3.** Multiple official and model forecasts (including local meteorological services, Yr.no, and others) converge on overnight radiative cooling under mostly clear to partly cloudy skies with light variable winds and negligible precipitation risk, producing minimum temperatures near 22–24°C. This setup favors efficient heat loss after sunset, differentiating the 21°C outcome (leading at 46.5%) from slightly warmer 24°C or cooler 18°C-or-below scenarios. No incoming fronts, monsoon moisture, or significant cloud cover are expected to moderate the cooling, consistent with the current continental high-pressure dominance. Historical early-September climatology in the region supports lows in this narrow band when clear conditions prevail, leaving limited room for major deviations absent last-minute model shifts.

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=zuck
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.
