Ongoing Huaxi autumn rain has established persistent cloud cover and light precipitation over Chengdu, suppressing daytime solar heating and capping highs near 25–26°C for September 23. Official forecasts from the Chengdu Meteorological Observatory and multiple models indicate scattered to moderate rain with highs of 23–26°C, consistent with historical late-September averages around 25°C under similar synoptic patterns. Differentiating outcomes hinge on exact rainfall timing and intensity—stronger or prolonged showers favor the 25°C or lower cluster by enhancing evaporative cooling and reducing insolation, while any temporary clearing could allow brief warming toward 27°C. Market-implied odds reflect this narrow uncertainty range, with traders weighting the latest model consensus and expected official updates ahead of resolution.

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=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.
