**Close market-implied odds for a 21–23°C low in Wuhan on September 3 reflect genuine uncertainty in overnight radiative cooling under mostly cloudy skies with light rain or drizzle.** Official forecasts from multiple sources converge on a daily minimum near 21–22°C, driven by northerly winds of 10–15 mph, high humidity near 70%, and persistent cloud cover limiting temperature drops after sunset. Early-morning observations around 22–23°C and a daytime high of 26–27°C leave the exact low sensitive to small changes in wind mixing, precipitation timing, and urban heat effects. Traders appear to weigh model consensus against historical September baselines, with resolution hinging on verified station data from the China Meteorological Administration.

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.
