Recent forecasts from multiple models, including GFS-based outputs, indicate a high near 24°C in Milan on September 24 under partly cloudy skies with light westerly to northwesterly winds and negligible precipitation risk. This consensus stems from stable high pressure and modest September climatology, where average daily maxima hover around 24–25°C without strong advection or instability. Minor model spreads—some runs peaking at 23°C, others briefly touching 25°C—explain the market's heavy weighting on 24°C (60.5%) while keeping 25°C and 23°C as viable secondary outcomes. With resolution imminent, traders appear to favor the central tendency of current guidance over outlier scenarios.

The resolution source for this market will be information from NOAA, specifically the highest 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.
