Aperture of a cool northerly flow and an incoming Atlantic perturbation are suppressing daytime heating over Milan on September 10, with widespread cloud cover, moderate-to-heavy rain, and surface cooling limiting the maximum temperature. Multiple forecast runs from regional and global models converge on afternoon peaks between 21–22 °C, though exact timing of heaviest precipitation and residual insolation under breaks in cloud could shift the observed high by 1 °C in either direction. This places the market-implied odds near the center of the ensemble spread, where traders weigh the balance between stronger frontal cooling that favors 21 °C and any late-day clearing that could briefly allow 23 °C. Updated model cycles and real-time surface observations through the morning will narrow the range before resolution.

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.
