Recent official forecasts and ensemble model runs from European meteorological centers indicate a stable high-pressure regime over northern Italy, with clear skies, light southerly flow, and minimal cloud cover expected to support a daily maximum near 32–33 °C in Milan on September 7. Surface observations from the preceding 48 hours show daytime highs of 33–34 °C under similar synoptic conditions, while the latest short-range guidance has trended slightly cooler, narrowing the most probable range to 31–32 °C. These data shifts explain the heavy market weighting toward 32 °C (63.5 %) and 31 °C (27.0 %), with only modest probability assigned to 33 °C. Final resolution will depend on the official station reading at Milano Linate or the designated Milan reference site, with the last model updates due overnight before the peak heating period.

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.
