Forecast models from sources including GFS and ECMWF indicate a mild overnight minimum for Milan on September 16 driven by southerly to southeasterly flow, high humidity near 90 percent at times, and variable cloud cover that restricts radiative cooling. Light winds and possible scattered showers further moderate temperatures, keeping the low near or slightly below the seasonal average rather than allowing sharper drops. Trader consensus clusters tightly around 18–19°C because small differences in the timing and extent of overnight cloud breaks or urban heat island effects can shift the exact hourly minimum by 1°C. Updated short-range guidance and station observations will resolve whether the reading settles at the higher or lower end of this narrow range before the market closes.

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.
