Current forecasts from GFS and ECMWF guidance indicate a minimum temperature near 16–17°C for Milan on September 20 under high pressure, light winds, and partly cloudy skies that limit radiative cooling. This setup favors typical late-summer overnight lows, yet the near-even market odds between 20°C or higher and 10°C or below reflect model spread in cloud cover and boundary-layer mixing, which can shift the exact minimum by 2–3°C. Traders weigh these variables ahead of final observational data, with resolution hinging on the official recorded low.

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=limc
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.
