Official forecasts from the Wuhan Meteorological Observatory and multiple global models project a September 20 high of 28–30 °C under partly to mostly cloudy skies, light northerly winds, and moderate humidity levels typical of the Yangtze River valley in mid-autumn. This consensus, reinforced by the most recent 24-hour model runs showing no strong frontal passage or anomalous warming, positions 29 °C as the modal outcome with 28 °C and 30 °C as close alternatives. Cloud cover and limited insolation are expected to cap any upside potential, while the absence of significant precipitation or stronger advection keeps values above the lower tail of historical September maxima. Market-implied probabilities closely track these numerical weather prediction outputs, reflecting traders’ weighting of official guidance and ensemble spread.

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=zhhh
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.
