Persistent cloud cover and widespread rain across Chongqing, driven by regional weather patterns, are limiting nighttime radiative cooling and anchoring minimum temperatures near 20–22°C for September 21 according to current model consensus. These conditions, typical in the city's humid subtropical climate during late September, raise the floor on lows compared to clearer periods that could permit drops to 16°C or below via stronger outgoing longwave radiation. Conversely, any unexpected warm-air advection or reduced precipitation could lift readings toward or above 26°C. Traders appear to weigh these variables closely, with upcoming CMA forecast updates and refined ensemble runs likely to clarify the balance between moisture-driven moderation and potential variability.

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.
