Forecast models from multiple agencies indicate Zhengzhou's overnight low on September 18 will likely fall between 17–20°C, driven by moderate southerly winds, increasing cloud cover that limits radiative cooling, and light drizzle chances reducing temperature drops. These conditions align with seasonal norms for mid-September in the North China Plain, where daytime highs near 27–29°C give way to gradual nocturnal declines without strong cold-air advection. Trader odds remain near parity between sub-15°C and 25°C+ outcomes because ensemble spreads reflect minor variations in humidity, wind speed, and exact timing of any precipitation, with resolution hinging on official minimum readings from local stations. Updated model runs tonight and early morning observations will clarify whether clearer skies allow further cooling or persistent clouds hold temperatures 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.
