Recent northerly winds and the White Dew solar term have driven cooler air into central China, positioning Wuhan for a notable drop in overnight lows ahead of September 10. Official forecasts from multiple meteorological sources converge on minimum temperatures near 18–20°C that night, with some model runs suggesting potential for brief dips into the upper teens amid partly cloudy skies and dew points in the mid-teens Celsius. This cooling trend, following sustained highs near 30–34°C earlier in the week, accounts for the elevated market-implied odds on outcomes at or below 19°C while leaving room for variance from exact timing of the frontal passage or local urban heat effects. Updated model runs and official briefings from Chinese meteorological agencies in the next 24–48 hours will likely refine the precise minimum before 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 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.
