**Forecast models for Qingdao on September 18 show a spread in expected overnight lows centered around 19–22°C, with trader odds reflecting genuine uncertainty between warmer maritime air and potential for clearer, cooler conditions.** Persistent southeast winds from the Yellow Sea are maintaining mild, humid air masses that limit radiative cooling after sunset, while variable cloud cover—ranging from partly cloudy to overcast in recent runs—directly influences how much heat escapes overnight. A stable high-pressure setup supports the higher-end outcomes near 26°C or above by suppressing strong cold advection, yet any increase in clear skies or slight wind shift could enhance cooling toward the 16°C threshold or below. Historical September baselines for the coastal city average lows near 18°C, underscoring how small changes in boundary-layer moisture and insolation timing differentiate the closely matched market segments. Updated model guidance expected in the next 24 hours could narrow this range ahead of 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=zsqd
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.
