Latest numerical weather prediction runs indicate Milan’s minimum temperature on September 21 will likely fall between 17–19 °C under persistent high pressure, light northerly flow, and clear to partly cloudy skies that allow efficient nocturnal radiative cooling in the Po Valley. Ensemble spreads from ECMWF and GFS show modest uncertainty tied to exact cloud cover timing and boundary-layer mixing, producing the near-even split between the 20 °C+ and sub-10 °C market bins. Official observations at Milan Linate or Malpensa will determine resolution, with final model updates expected overnight.

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.
