Persistent cloud cover, high humidity near 85-95%, and light variable winds across the Sichuan Basin are limiting nocturnal radiative cooling, keeping the daily minimum temperature in Chengdu anchored near 20-21°C according to multiple model runs. These stable, moist conditions—typical of late-summer monsoon influence—reduce the usual 5-7°C diurnal range and create tight clustering of forecast minima between roughly 19-22°C. Official guidance from regional meteorological services shows only minor variations in overnight lows depending on exact timing of any light rain or fog development, which explains why market-implied probabilities remain closely balanced across the 17-21°C outcomes rather than converging on a single value. Updated model runs and station observations through the night will be the key near-term drivers of any shifts in trader positioning.

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=zuuu
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.
