Current forecasts from multiple models show clear skies and light winds over Milan on September 4, favoring strong nighttime radiative cooling that should drive the daily minimum into the 18–20°C range. Trader consensus clusters tightly on 18°C and 19°C because subtle differences in boundary-layer moisture, urban heat-island retention, and exact wind speeds near dawn can shift the low by 1°C. Recent model runs remain consistent with historical early-September climatology for the Po Valley, where calm high-pressure conditions typically produce minima 2–4°C below daytime peaks. Updated guidance expected overnight will clarify whether any slight increase in low-level humidity or a brief wind shift alters the final reading before market resolution.

The resolution source for this market will be information from NOAA, specifically the lowest 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.
