Recent meteorological forecasts for Milan indicate a daily maximum temperature near 24°C on September 17 amid scattered thunderstorms, elevated cloud cover, and easterly flow that limits daytime heating. This aligns with climatological norms of 24–25°C for mid-September at the site, following warmer conditions on the 16th. Trader consensus favoring 26°C or higher (56% implied probability) likely reflects residual model uncertainty in convective timing and potential for brief clearing that could allow brief spikes toward 25–26°C, while lower-probability outcomes account for heavier rain suppressing the peak. Updated model runs from agencies such as those using GFS data and official station observations expected overnight will provide the final resolution inputs.

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.
