Recent forecast model runs from sources including ECMWF and national meteorological services indicate an overnight low in Amsterdam on September 22 likely between 10–14 °C, with the market-implied odds reflecting tight clustering around 10–12 °C due to modest differences in predicted cloud cover, wind direction, and boundary-layer mixing. Southerly flow under mostly cloudy skies should limit radiative cooling compared with clearer conditions, while dew points near 10–12 °C and light winds favor minimums near the historical September average of 10.4 °C rather than the warmer 14–15 °C some guidance suggests. Updated model runs and observational data from Schiphol station tomorrow morning will provide the decisive inputs for resolution, underscoring the inherent spread among ensemble members at this short lead time.

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.
