Current forecast models from agencies like the National Weather Service equivalents and ensemble runs indicate Madrid's overnight low on September 21 will fall to 14°C or below, driving the near-certain market-implied odds for that outcome. Clear skies, light northerly winds, and radiational cooling under high pressure support efficient heat loss from the surface after daytime highs near 30–32°C. Historical September minimums average around 14–15°C, providing climatological context for the positioning. Traders' real-capital consensus reflects this model agreement, though realistic challenges include unexpected warm advection, increased cloud cover, or forecast revisions from updated runs that could push the low above 14°C before resolution.

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=lemd
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.
