Ensemble forecasts from leading numerical weather prediction models like ECMWF and GFS drive the tight clustering of market-implied probabilities around 16–18°C for Milan's highest temperature on March 28, reflecting a mild southerly airflow and high-pressure ridge over northern Italy. Trader consensus favors 17°C at 27% due to the ensemble mean hovering near that mark, with slight divergences: warmer 18–20°C outcomes (24–17%) gaining from optimistic GFS runs showing clearer skies and subsidence warming, while cooler 15–16°C bids (25–15.5%) hedge against potential cloud intrusions from residual Atlantic lows. Historical late-March highs in Milan average 14–15°C but exhibit 2–3°C model spread this close to event time, underscoring uncertainty in boundary layer mixing and urban heat effects.

The resolution source for this market will be information from Wunderground, specifically the highest temperature recorded for all times on this day by the Forecast for the Malpensa Intl Airport Station once information is finalized, available here: https://www.wunderground.com/history/daily/it/milan/LIMC.
To toggle between Fahrenheit and Celsius, click the gear icon next to the search bar and switch the Temperature setting between °F and °C.
This market can not resolve to "Yes" until all data for this date has been finalized.
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.
Any revisions to temperatures recorded after data is finalized for this market's timeframe will not be considered for this market's resolution.
