Recent forecasts from European models indicate a minimum temperature for Milan on September 23 likely near 16–18°C under partly cloudy skies and light easterly flow, yet the balanced market odds reflect notable ensemble spread. ECMWF runs favor milder overnight conditions with limited radiative cooling, while GFS members introduce cooler scenarios from subtle eastern air intrusions near the autumnal equinox. Key variables include cloud cover reducing heat loss, wind speeds modulating boundary-layer mixing, and surface pressure gradients that could shift dew points or trigger localized cooling. Traders are pricing genuine forecast uncertainty ahead of the next model updates, as small changes in overnight stability could push the low across multiple resolution thresholds.

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.
