Recent official forecasts from sources including the China Meteorological Administration and international models indicate a highest temperature near 28–29°C in Chongqing on September 13, supported by partly to mostly cloudy skies and a 30–50% chance of light rain under northwest flow. Cloud cover and precipitation act as the main variables separating the tightly clustered 25–27°C outcomes: increased moisture and reduced insolation from rain or thicker clouds would cap daytime heating near the lower end, while clearer breaks could allow surface temperatures to reach 28°C before cooling. Model runs show modest spread in boundary-layer moisture and timing of any showers, creating the narrow probability distribution among the three leading resolutions. Updated short-range guidance expected within 24 hours will likely narrow this range further.

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.
