ROME — Italy is experiencing a significant change in weather conditions as an Atlantic disturbance moves across the country, bringing rain, thunderstorms and a sharp decline in temperatures after an unusually long period of hot weather

A report published on September 10, 2026, said temperatures in parts of northern and central Italy have fallen by as much as 8–10 degrees Celsius as cooler oceanic air interacts with the warmer air mass that had dominated the country.

The weather system, originating from the North Atlantic region, has already affected northern areas and is moving progressively toward central and southern parts of Italy. Several regions are experiencing unstable conditions, with heavy showers and thunderstorms possible.

Tuscany is among the areas expected to experience potentially intense thunderstorms, while parts of the northeast, including Veneto and Friuli Venezia Giulia, are also facing significant rainfall.

During Thursday, September 10, the unstable weather is expected to reach Rome and much of Lazio, before extending toward parts of the central Apennines and Campania. Some areas could experience locally heavy rainfall and thunderstorms.

The temperature contrast across the country is particularly noticeable. While central and northern cities are seeing considerably cooler conditions, parts of southern Italy remain hot. Temperatures in some areas of Puglia could still reach around 35°C.

Meteorologists are also warning about the possibility of intense thunderstorms, hail and localized flooding in areas affected by the strongest storms. The combination of accumulated heat and moisture has created conditions capable of producing powerful convective weather.

The change marks the end of an unusually persistent period of summer heat. However, forecasters expect the unsettled spell to be relatively short-lived.

Weather models indicate that conditions should begin improving toward the weekend as atmospheric pressure rises. Much of northern and central Italy could see more sunshine from Saturday, while southern regions are expected to improve progressively.

By Sunday, weather conditions are expected to become more stable across much of the country, with temperatures returning to more comfortable September levels.

The latest weather development provides relief from the prolonged heat but also requires caution in areas vulnerable to intense rainfall, flash flooding and thunderstorms during the transition.
