Recent forecasts for Chongqing on September 15 indicate a high near 22–24°C amid increasing cloud cover, light rain, and elevated humidity from an approaching frontal system, which limits solar heating and explains the tight clustering of market-implied probabilities around those values. Official guidance from sources such as the China Meteorological Administration and global models shows daytime maxima suppressed below the September climatological average of 27–28°C due to persistent overcast skies and precipitation probabilities exceeding 70% in several runs. Minor model disagreements on exact timing of showers and boundary-layer mixing create the narrow spread between 22°C and 24°C outcomes, while warmer or cooler extremes remain low-probability given the stable synoptic pattern. Updated model guidance and surface observations through the evening of September 14 will provide the final data points for 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=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.
