Recent ECMWF and GFS ensemble runs for northern Italy indicate a 28–31°C range for Milan’s August 23 maximum, with modest spread tied to the timing and extent of thundery showers. These forecasts reflect a warm southerly flow under a broad ridge, tempered by increasing cloud cover and possible convective cooling that could cap peaks near 28°C or allow brief clearing to push above 29°C. Historical August climatology shows mean highs of 28–29°C, so current guidance sits close to seasonal norms rather than an extreme. Traders have priced the 29°C-or-higher bucket at 38.5% because the latest model cycles favor slight upward revisions, while the tight clustering around 27–28°C outcomes (53.5% combined) captures lingering uncertainty in boundary-layer moisture and exact shower timing. The next 48-hour model cycle and official observations will be decisive before resolution.
