Recent forecasts from GFS, ECMWF, and local guidance indicate an unsettled Atlantic low-pressure system driving southwesterly flow and widespread showers or thunderstorms into the Netherlands on August 31, yielding expected overnight minima of 15–16 °C in Amsterdam. Persistent cloud cover and elevated dew points limit nocturnal radiative cooling while suppressing daytime maxima near 19–21 °C, keeping the daily minimum close to the seasonal average rather than cooler anomalies seen earlier in the month. Ensemble spreads and model-to-model differences in boundary-layer moisture and exact timing of showers create the tight clustering around 14–16 °C, with traders assigning the highest implied probabilities to these central outcomes amid typical forecast uncertainty two days ahead.

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.
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
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.
