**Forecast uncertainty from a passing weather system and variable nocturnal cooling is the main driver of the closely matched market odds.** Recent thunderstorms and showers across northern Italy on September 17 have introduced cooler, moister air with elevated dew points, while lingering clouds and light easterly winds on the 18th limit radiative cooling overnight. Ensemble guidance from ECMWF and GFS shows minimum temperatures clustered around 16–18°C, but small shifts in cloud cover, precipitation timing, or boundary-layer mixing could push the daily low several degrees lower (favoring the 12°C-or-below bucket) or keep it milder (supporting outcomes near or above 20–22°C). Historical mid-September minima in Milan average near 16°C, so the near-even split between the leading buckets reflects genuine model disagreement rather than a strong directional signal. Updated high-resolution runs and clearer satellite trends ahead of the 18th will likely narrow the range before 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.
