Current forecast models point to overnight lows near 12–15°C in Amsterdam on September 23 under building high pressure and light southerly flow, yet the near-even market odds between ≤7°C (50%) and ≥17°C (48%) reflect uncertainty in cloud cover and wind shifts that control radiative cooling. Clear skies overnight enhance surface heat loss through longwave radiation, potentially dropping temperatures several degrees below guidance, while increased cloudiness or a stronger southerly advection of milder maritime air would limit cooling and support higher minima. Ensemble spreads in ECMWF and GFS runs highlight this sensitivity, with resolution depending on the exact timing of any weak frontal passage and updated observational data from KNMI stations.

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.
