Recent forecasts from multiple models indicate a moderating high around 26–29°C for Wuhan on September 16, driven by an advancing cooler air mass from the northeast, increased cloud cover, and light easterly winds that limit daytime heating. Surface observations on September 15 showed highs near 29–30°C under partly cloudy skies, but guidance for the following day points to greater moisture and a 20–35% chance of light rain or drizzle, which would suppress peak temperatures. Model consensus places the most likely outcomes near 27–28°C, aligning with the tight market distribution, while resolution hinges on official daily maximum readings from local stations amid typical early-autumn variability in the Yangtze River valley.

The resolution source for this market will be information from NOAA, specifically the highest 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.
