Recent atmospheric conditions over Chongqing, including persistent cloud cover, high humidity near 90-95%, and ongoing light rain or showers, are suppressing radiative cooling and anchoring overnight lows near 21-22°C. Multiple forecast models show consensus on these mild temperatures for September 23 due to weak pressure gradients and light variable winds, limiting diurnal temperature swings. Trader emphasis on the 20°C outcome reflects this stability, while the 16°C-or-below probability accounts for potential model underestimation of clearing skies or enhanced evaporative cooling from recent precipitation. Official minimum readings from Chongqing Jiangbei International Airport will resolve the market, with the next 24-hour observational updates likely to refine the narrow range between 20°C and 22°C.

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.
