**Persistent cloud cover, light rain, and high humidity on September 20 are keeping overnight radiative cooling limited in Zhengzhou, supporting market-implied odds clustered tightly around 19–20 °C for the daily minimum.** Forecasts from multiple models show the city under overcast skies with light northerly winds and scattered showers throughout the day and into the night, which trap heat near the surface and reduce the diurnal temperature range. This setup aligns with typical early-autumn conditions in the North China Plain, where September lows average near 17 °C but can remain several degrees higher under persistent moisture and weak winds. Model consensus points to a minimum near 20–21 °C, with small differences in exact timing of rainfall or wind shifts creating the narrow spread between the leading 19 °C and 20 °C outcomes. Official station readings, likely from the Zhengzhou national reference climate station, will determine resolution once the full 24-hour period is complete.

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.
