Latest numerical weather models indicate overnight radiative cooling under mostly clear to partly cloudy skies will produce a minimum temperature in Wuhan of 27–29°C on August 27, aligning with the tightly bunched market-implied probabilities around those outcomes. Light easterly or northeasterly winds near 5–10 km/h, combined with dew points around 24–26°C and moderate humidity of 55–65%, limit further cooling while the urban heat island effect raises baseline lows relative to rural areas. Ensemble spreads show modest uncertainty tied to small variations in cloud cover and wind speed, with any increase in low-level moisture or calm conditions potentially nudging the minimum toward 25–26°C. Updated model runs and satellite observations over the next 48 hours will refine these thresholds ahead of market 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=zhhh
If NOAA data is unavailable or missing for the observation period, Weather Underground will be used as the secondary 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.
