Latest ensemble forecasts from European and global models show Amsterdam's overnight minimum on September 20 shaped by an approaching Atlantic low-pressure system and associated frontal cloud band. Persistent southwest flow advects milder maritime air while variable cloud cover modulates nocturnal radiative cooling; thicker overcast tends to hold temperatures near 14–15°C, whereas partial clearing allows greater heat loss toward 13°C or below. Historical September minima average near 11°C, but current above-normal warmth and moisture increase the chance of a milder outcome. Traders assign highest implied probability to 13–14°C, reflecting tight model spread on wind speed and shower timing that will determine the precise low before official KNMI verification.

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.
