Recent cold air advection and increasing cloud cover ahead of a frontal passage are suppressing daytime heating in Chongqing, shifting trader focus toward a September 10 high near 29–31 °C. Official guidance from regional meteorological services indicates the maximum will likely occur under mostly cloudy to overcast skies with scattered showers, limiting solar insolation and yielding surface temperatures several degrees below the preceding week’s 35–37 °C readings. Model spread centers on the precise timing of the coolest air and rainfall rates, which directly influence the afternoon peak; lighter or later precipitation could allow brief warming to 30–31 °C, while earlier or heavier rain favors 28–29 °C. Historical September climatology shows rapid cooling episodes of this magnitude are common when northerly flow strengthens behind the subtropical ridge. Updated short-range guidance and observed 2 m temperatures tomorrow morning will refine the market-implied distribution.

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=zuck
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.
