**Recent model consensus points to a minimum temperature in Chengdu near 20–21°C on September 21, with modest radiative cooling under mostly cloudy skies and light southerly or southwesterly winds limiting overnight drops.** High humidity (around 70–85%) and a slight chance of showers further suppress temperature swings by enhancing downward longwave radiation and reducing net heat loss. Official and ensemble forecasts from sources such as GFS-based guidance show overnight lows clustered between roughly 19–21°C (about 66–70°F), consistent with late-September climatology for the Sichuan basin where typical minima hover near 19°C. The tight clustering of market-implied probabilities around 19–21°C reflects this narrow forecast envelope, while lower-probability tails for 16°C or below capture residual uncertainty from potential clearer breaks or heavier rain that could either enhance or suppress cooling. Updated model runs and any last-minute shifts in cloud cover or precipitation will be the key near-term drivers.

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=zuuu
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.
