Current forecasts from multiple models place Zhengzhou's overnight low on September 6 near 20–21°C under clear skies and light easterly winds, consistent with typical early-September climatology for the region. The near-even split between sub-15°C and 25°C+ outcomes, alongside clustered probabilities around 20–21°C, reflects trader focus on minor forecast adjustments from incoming data, such as slight variations in dew point or boundary-layer mixing that could shift the minimum by 2–3°C. Official observations from central Henan stations will resolve the market, with any unexpected cloud cover or advection from the north likely to exert the strongest downward pressure on the reading.

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=zhcc
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.
