Recent official forecasts from sources like WeatherBug, Yr, and Luft Time project Zhengzhou’s overnight low for September 6 around 21–24 °C under mostly clear skies and light easterly winds that favor moderate radiative cooling after a daytime high near 31 °C. Trader consensus heavily favors 18–19 °C because models show a modest downward revision in minimum temperatures amid stable high pressure and low humidity, increasing the chance the official station reading dips below the seasonal norm. With resolution tied to the day’s recorded minimum, any further evening cooling from clearer-than-expected conditions or slight wind shift could lock in the lower end of the distribution, while persistent warmth would push outcomes higher.

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.
