A frontal system approaching from the north is driving cooler, moister air into northern Italy, with east-northeasterly winds and increasing cloud cover expected to limit daytime heating in Milan on September 10. Official forecasts from sources including ILMeteo and numerical models show daytime maxima clustered between 21–23 °C under partly cloudy skies and a chance of light showers, following thunderstorms on the 9th that have already initiated the seasonal cooldown. This range aligns with the tight market clustering around those outcomes, where differences hinge on precise cloud timing, precipitation intensity, and boundary-layer mixing—variables that can shift the peak by 1–2 °C. Updated high-resolution model runs overnight will likely narrow the remaining uncertainty 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.
