Recent cooling from prior heat and widespread cloud cover with light rain have positioned Chongqing's overnight low near 20–22°C, driving tight market-implied odds around those levels. Official forecasts from local meteorological sources indicate minimums of 20–21°C amid southwest winds and high humidity that limit radiative cooling, consistent with September climatology where average lows hover near 21–22°C. Model runs show minor divergence on exact timing of clearing, with any earlier dissipation potentially allowing a dip toward 20°C or below while persistent overcast supports 21–22°C. Updated observations tonight will refine 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=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.
