**Cold air advection from the north, combined with widespread rain and thunderstorms, is the dominant driver cooling Wuhan on September 17.** Official forecasts from multiple agencies and models converge on a daytime high of 22–23°C under overcast skies, northeast winds of 5–12 km/h, and high precipitation probability (70–100% chance of rain or thunderstorms). This marks a sharp 8–10°C drop from mid-September peaks near 30–34°C. The market’s heaviest weighting on 22°C (37.5%) followed by 21°C and 23°C reflects this consensus while capturing residual uncertainty in exact maximum readings amid variable rainfall timing and cloud cover. Historical September analogs and current model runs support limited upside beyond 24°C under these synoptic conditions.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Wuhan Tianhe International Airport Station in degrees Celsius on 17 Sep '26.
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.**Cold air advection from the north, combined with widespread rain and thunderstorms, is the dominant driver cooling Wuhan on September 17.** Official forecasts from multiple agencies and models converge on a daytime high of 22–23°C under overcast skies, northeast winds of 5–12 km/h, and high precipitation probability (70–100% chance of rain or thunderstorms).
