Recent official forecasts from multiple models indicate a minimum temperature near 20–21°C for Zhengzhou on September 4 under clear skies and light northeast winds. This setup favors radiational cooling overnight following daytime highs around 29–31°C, with dew points in the mid-teens Celsius limiting further drops. The closely matched market-implied odds around 45–50% across 15–25°C thresholds reflect modest ensemble spread in global models, typical for 24-hour minimum temperature predictions in stable high-pressure regimes. No incoming fronts or moisture surges are expected to alter the pattern before resolution, though subtle variations in boundary-layer mixing or wind speed could shift the exact low by 1–2°C. Updated short-range guidance from agencies like the China Meteorological Administration will provide the final calibration.

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.
