Recent forecasts from European meteorological models indicate a cool front and associated rainfall will suppress daytime heating in Milan on September 10, driving market-implied probabilities toward 20–22°C as the most likely daily maximum. Persistent easterly flow, high cloud cover, and widespread precipitation—expected to peak midday—limit solar insolation and evaporative cooling, aligning with consensus projections of 19–22°C highs from sources such as the ECMWF and GFS ensembles. This marks an 8°C drop from prior days, consistent with the passage of a mid-latitude disturbance. Traders have priced modest upside risk to 23°C if rain arrives later than modeled, while lower outcomes reflect minimal probability under current synoptic conditions. Updated model runs and official observations tomorrow morning will refine resolution.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the Malpensa Intl Airport Station in degrees Celsius on 10 Sep '26.
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.Recent forecasts from European meteorological models indicate a cool front and associated rainfall will suppress daytime heating in Milan on September 10, driving market-implied probabilities toward 20–22°C as the most likely daily maximum.
