**Clear skies and light northeast winds are expected to drive efficient nighttime radiative cooling in Wuhan on September 6, with official forecasts converging on a minimum near 21°C.** Multiple meteorological sources, including Chinese weather services and international models, project a low of 20–23°C under mostly clear conditions following daytime highs around 32°C. This aligns with early September climatology for the region, where calm nights and moderate humidity typically produce modest diurnal ranges without significant cold advection or precipitation. Market-implied probabilities remain closely bunched (20°C leading at 36%, with 16°C-or-below and 26°C-or-higher each near 30%) because small differences in boundary-layer moisture, wind speed, or urban heat retention can shift the exact minimum by 1–2°C. Traders appear to weigh the high consistency of current model runs against the inherent uncertainty in precise overnight minima. The China Meteorological Administration’s final verified observation will resolve the market.

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 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.
