Traders see the lowest temperature in Zhengzhou on August 30 clustering tightly around 22–23°C because ensemble forecasts from regional models show substantial overlap in expected overnight minima, driven by comparable boundary-layer conditions. Persistent subtropical high pressure favors clear to partly cloudy skies that allow efficient radiational cooling after sunset, while light southerly flow and moderate humidity levels limit further drops. Small differences in cloud timing, wind speed above 2 m/s, or boundary-layer moisture could easily shift the minimum by 1°C between the two leading outcomes. Historical late-August climatology places typical lows near 21–24°C, reinforcing the market’s narrow spread. Newer model runs and local observations expected overnight will likely determine whether 22°C or 23°C resolves as the actual minimum.

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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
