Trader consensus on Polymarket prices a 40% implied probability for Milan's highest temperature reaching 23°C or higher on April 4, driven by the latest ECMWF ensemble forecasts showing a cluster of warmer members under a high-pressure ridge building over the central Mediterranean, potentially advecting subtropical air northward. Recent ARPA Lombardia observations confirm late-March highs averaging 19-22°C—well above the early-April climatological norm of 17°C—amid mild, sunny conditions from a blocking pattern. Competing outcomes around 20-22°C (21% each) reflect core model consensus, though inherent uncertainty in 5-day numerical weather prediction (NWP) arises from steering winds and cloud cover variability. Watch tomorrow's ECMWF 00Z run for refined guidance ahead of resolution.

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.
