Current forecast models from sources including the Met Office and regional analyses point to overnight radiative cooling under partly cloudy skies and light northeasterly winds, supporting minimum temperatures near 21–23°C in Zhengzhou on August 30. High humidity around 60–70% and dew points near 19–21°C will limit further cooling by reducing net longwave radiation loss, while weak pressure gradients suppress stronger advection of cooler air. Model spread arises mainly from subtle differences in predicted cloud cover and boundary-layer mixing, keeping implied probabilities tightly clustered around 18–21°C outcomes. Updated runs from NOAA and European centers ahead of the evening hours will likely resolve remaining uncertainty before resolution.

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.
