SITUATION. The Mediterranean anticyclone, which has often maintained stable conditions in the central regions and especially in the southern ones, will be weakened over the weekend by the lowering of the latitude of the depression of British origin, responsible for unstable weather in our northern regions to date. Rain and thunderstorms will therefore extend their action from Northern Italy to the central-southern regions starting from Saturday, especially those on the Adriatic side, while on Sunday a residual instability will linger in the South. At the same time a temporary strengthening of the anticyclone will favor a stabilization of the weather on Sunday in the Centre-North, however, it is destined to gradually end from the beginning of next week. But let’s see in detail the weather forecast for the weekend.
SATURDAY WEATHER. To the North showers and locals thunderstorms during the night in the Po Valley, especially between Lombardy and the North-West. Variability in the morning with wider clearings in the western Alps, some scattered showers in Lombardy, Veneto and Trentino. During the day there will still be some showers or thunderstorms forming between the central-eastern Alps and the central-eastern Po Valley, but also on the Emilia-Romagna Apennines and adjacent plain areas, everywhere tending to weaken in the evening with greater openings on the way. To the Center clouds increasing already in the morning on the Tyrrhenian side with some rain arriving on upper Tuscany and the Lazio coasts, initially sunnier on the Adriatic. From the afternoon rapid intensification of instability with rains and thunderstorms over much of the Apennine area, locally strong and accompanied by hail in the Marche and Abruzzo sectors, spilling over into the Adriatic coastal areas. In the evening, phenomena will attenuate and large clearings will arrive on the Tyrrhenian side. To the South Increasing clouds in the morning over the Tyrrhenian Sea and Sicily with showers in Campania, eastern Sicily and lower Calabria. From the afternoon rains and thunderstorms moving from Campania, to Lucania and central-northern Puglia, showers also on Sicily and Calabria, by the evening up to Salento. In the evening, attenuation of the phenomena on Sicily and the Tyrrhenian Sea with partial clearing arriving. In Sardinia instability increasing already in the morning with some showers or thunderstorms in inland areas, locally encroaching on the Tyrrhenian coast but improving from the west between afternoon and evening. Temperatures decreasing.
SUNDAY WEATHER. To the North good weather returns to prevail, except for some variability in the Alpine areas in the afternoon, with local short showers more likely in Piedmont and Friuli VG. To the Center Stable conditions prevail with mostly sunny weather, except for some showers or thunderstorms in the afternoon in the Apennine areas between lower Marche, Lazio and Abruzzo. To the South sunny in Sicily, scattered clouds in the morning over the peninsular regions; instability increasing from the afternoon in the Apennine areas with showers and thunderstorms locally encroaching on the Tyrrhenian coasts, but easing in the evening. In Sardinia stable and mostly sunny weather. Temperatures rising in the Centre-North, falling in the South.

Even in high pressure conditions, in the height of summer, short, localized but sometimes intense thunderstorms can suddenly form and surprise us: they are the so-called ‘heat storms’ and are more likely between late afternoon and early evening.
