Recent forecasts from major models including ECMWF and GFS indicate a high-pressure system with clear to mostly clear skies and light southerly winds over Milan on September 14, supporting surface heating to a maximum near 27–28°C. This exceeds the September climatological average high of roughly 22–24°C due to a warmer-than-normal air mass advected from the south. Ensemble guidance shows limited spread, with most runs clustering between 26–29°C and minimal precipitation risk, positioning 28–29°C as the dominant outcomes in trader consensus. Updated model runs through the morning of September 13 have reinforced this range without significant upward revisions.

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.
