Persistent light rain and extensive cloud cover over Chongqing on September 16 are capping daytime heating, with official forecasts from local meteorological services showing highs of 20–23°C amid high humidity near 90% and light variable winds. These conditions suppress surface warming by limiting solar insolation and enhancing evaporative cooling, keeping maximum temperatures tightly clustered around the 20–21°C thresholds that dominate market-implied odds. Minor differences in forecast model timing of showers and exact cloud thickness create the narrow spread between leading outcomes, while historical September baselines for the region typically allow higher peaks under clearer skies. Updated observations through the afternoon will determine the precise daily maximum recorded by monitoring stations.

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=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.
