Recent ensemble forecasts from ECMWF and GFS models indicate moderate uncertainty in the overnight minimum over Amsterdam on September 15, with projected lows clustered near 15–17 °C amid southerly flow and increasing cloud cover. High pressure initially supports mild conditions, but a weak frontal passage and possible showers late in the period introduce variability in boundary-layer cooling and dew-point depression. Historical September minima average 11 °C, yet current 48-hour guidance shows limited spread toward either sub-12 °C radiational cooling or sustained 20 °C warmth, producing the balanced 46 % market-implied odds on those tails. Updated model runs and surface observations in the next 24 hours will refine the timing of any showers and resulting minimum.

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.
