Recent ensemble forecasts from major models indicate a high near 25–26°C for Milan on September 22, driven by building high pressure and an easterly flow that moderates daytime heating despite mostly clear skies. Light to moderate easterly winds of 6–12 km/h, combined with limited cloud cover and negligible precipitation, support stable maximum temperatures after warmer conditions earlier in the week. The tight spread between 25°C and 26°C outcomes reflects typical ensemble uncertainty in boundary-layer mixing and exact wind timing rather than major discrepancies in synoptic patterns. Updated model runs and official Italian meteorological guidance over the next 48 hours will provide the clearest signals for final 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 22 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 ensemble forecasts from major models indicate a high near 25–26°C for Milan on September 22, driven by building high pressure and an easterly flow that moderates daytime heating despite mostly clear skies.
