Forecast uncertainty for Amsterdam's September 23 overnight minimum stems from evolving model consensus on cloud cover, wind patterns, and air mass advection ahead of a possible frontal passage. Clearer skies would enhance radiative cooling and favor readings near or below 11–13°C, while increased low-level moisture or showers could limit drops to 14°C or higher. Recent ECMWF and GFS runs show modest spread in boundary-layer temperatures, with historical September climatology placing average lows near 10°C. Traders are weighting these variables evenly across outcomes because the next 48-hour model updates and observational data could shift the balance 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=eham
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.
