**Persistent rain and extensive cloud cover over Chengdu are the dominant factors holding the overnight low near 18–19 °C on September 15.** Multiple forecast models show a saturated boundary layer with high humidity (85–93 %) and light northerly flow, which limits nocturnal radiative cooling while daytime heating remains modest under overcast skies. This produces a narrow diurnal range typical of late-summer monsoon remnants rather than a sharp autumn chill. Historical September climatology places average lows near 19 °C, with occasional drops to 15–16 °C only under clearer, drier conditions that are not currently expected. The near-even market split between the 24 °C+ and ≤14 °C bins reflects uncertainty in how much additional cooling any late-model shift or brief clearing could produce before the minimum is recorded.

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.
