The autumnal anticipation with a temperature drop of 15°C, rain, wind and even snow is approaching. A meteorological impulse will hit Italy this evening with initial thunderstorms in the Alps and Prealps, which will extend to the Po Valley during the night. From Thursday to Friday, this meteorological phenomenon will extend to the entire nation. In the meantime, in the next few hours, it will continue to be sunny with maximum temperatures reaching 32°C in Sicily, 31°C in Puglia and even 30°C in Emilia Romagna (Forlì) and Umbria (Terni), 29°C in Ferrara, Florence, Naples, Rome and Pesaro. However, in the next 48 hours, some cities will see their maximum temperatures halve; Bologna, for example, will go from around 30°C to less than 20°C on Friday. On Friday, almost all of Central-Northern Italy will have typical autumnal maximum temperatures, around 20 degrees, which was the minimum temperature in recent days. It is a temperature that in recent years has rarely lasted for many days in September and this autumn phase will be quite prolonged. There will be a drop of up to 15°C, snow will fall on the Alps up to 1500-1700 meters (on the border mountains up to 1100 meters), there will be heavy rain and an intensification of the wind. In particular, after a sunny Wednesday, ruined in the evening by the arrival of the polar cyclone, we will have a Thursday with rain and thunderstorms especially in the North-East and in the central regions; on Friday the rain and the drop in temperatures will also hit the South while there will be an improvement in the North and in the central Tyrrhenian regions.
Over the weekend, we expect some sunshine, although temperatures are forecast to be decidedly autumnal. Only Sicily and Calabria are forecast to have 27°C; in the rest of Italy, temperatures will drop, not exceeding 25°C. Rome, Oristano and Cagliari are forecast to have 24 degrees, while Lecce should not exceed 23°C. In general, the rest of the country will struggle to reach 19°C during the hottest hours; the last time we recorded maximum temperatures this low was in mid-October last year, and in some places only from November onwards. On top of that, we expect colder temperatures at night, with minimums dropping into single digits; for example, in Milan we expect 7-8°C at dawn throughout the weekend.
