Recent northerly cold air advection across Henan has sharply suppressed temperatures in Zhengzhou on September 9, producing overcast skies, light rain, and northerly winds that limit daytime solar heating. Official forecasts and station observations consistently indicate a daily maximum near 17–18°C, well below the long-term September average high of roughly 27°C. With the afternoon period already under way and no significant warming expected, the 22°C-or-below outcome commands overwhelming market-implied odds near 100%. Only an unforecasted late-day temperature spike or measurement revision at the official station could realistically alter resolution.

The resolution source for this market will be information from NOAA, specifically the highest 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.
