Latest numerical weather prediction runs from global models such as GFS indicate overnight lows in Amsterdam on September 21 will likely settle near 12–13 °C under mostly cloudy skies and light westerly winds, limiting radiative cooling. This aligns with the closely matched market-implied probabilities for those two outcomes. A stable high-pressure ridge and mild maritime air mass are suppressing stronger cooling that historically produces sub-10 °C readings, though modest model spread in cloud timing and boundary-layer mixing keeps lower thresholds like 7 °C or below at 24 % implied odds. The climatological average minimum for the date is 10.5 °C, providing context for why traders favor the upper end of the distribution ahead of final overnight observations.

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.
