Latest ensemble forecasts from ECMWF and GFS models point to minimum temperatures near 18–19°C in Milan on September 14, driven by clear skies, high pressure, and light northeasterly winds that limit nocturnal radiative cooling. Trader-implied odds spread across 16–21°C outcomes reflect model variability in boundary-layer mixing and urban heat-island effects at official measurement sites. With probabilities clustered between 25–30% for the top bins, markets price genuine short-term uncertainty in exact overnight lows rather than a single consensus value. Updated model runs overnight and early-morning observations will likely tighten resolution ahead of the daily 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=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.
