Adnkronos (Adnkronos) – Meteo in peggioramento sull’Italia per l’arrivo di una perturbazione atlantica che attraverserà la Penisola tra venerdì 23 e sabato 24 ottobre. Sono attese piogge diffuse soprattutto al Nord e sulle regioni centrali, accompagnate da un calo delle temperature massime di 2-3°C. Domenica 25 ottobre tornerà il tempo stabile su gran parte del Paese, ma il rasserenamento notturno e l’afflusso di aria più fredda favoriranno temperature minime basse, soprattutto in Pianura Padana.
La nuova settimana, invece, si aprirà all’insegna dell’anticiclone e di un progressivo rialzo termico.
Lorenzo Tedici, meteorologist and media editor at iLMeteo.it, confirms that the frontal system's origin lies in the deepening of a vast oceanic trough. This marked development of a low pressure system over the British Isles (a phenomenon known in meteorology as cyclogenesis) will channel moist, cool, and unstable air masses directly toward the Mediterranean basin.
La perturbazione porterà precipitazioni a partire dalla tarda mattinata sulla Liguria di Levante, con accumuli stimati localmente superiori ai 50 mm in 12 ore.
Successivamente i fenomeni si estenderanno verso l’Emilia-Romagna e la Toscana, con quantitativi medi compresi tra 20 e 30 mm/24h. Dalla serata le piogge raggiungeranno buona parte del Nord-Est, accompagnate da nevicate lungo l’arco alpino orientale durante la notte a quote comprese tra 1700 e 1900 metri. Il Meridione rimarrà ai margini del peggioramento con ampie schiarite.
Nella giornata di sabato il fronte scivolerà progressivamente verso sud-est lungo la fascia adriatica.
Le precipitazioni interesseranno in modo più continuo l’Abruzzo, il Molise e il Gargano, apportando cumulati stimati tra i 15 e i 40 mm/24h. Contestualmente, si registrerà un ulteriore calo termico di 2-3°C sulle regioni centrali, dove i valori minimi notturni scenderanno leggermente al di sotto delle medie climatologiche del periodo.
Sunday will be characterized by generally stable weather conditions, albeit with residual precipitation (less than 5-10 mm/24 hours) limited to the southern regions. The influx of colder air and clearing overnight will favor lows of 4-5°C in the Po Valley and a widespread drop in central Italy as well; highs will generally hover around 15-19°C, with localized higher peaks only in the south.
For the start of the new week, the models outline a significant expansion of the anticyclone field across much of the peninsula, which will guarantee stable weather and a temperature increase of 3-4°C (up to +6°C in the Tri-Veneto region), bringing temperatures everywhere above seasonal averages.
IN DETAIL
Friday the 23rd. In the North: Rain from late morning in eastern Liguria (over 50 mm/12 hours), spreading to Emilia-Romagna and Triveneto (20-30 mm/24 hours); snow level in the eastern Alps between 1700 and 1900 meters; highs dropping by 2-3°C. In the Central Region: Increasing clouds with rain in Tuscany, scattered clouds in Umbria and Marche. In the South and the Islands: stable weather.
Saturday 24th. In the North: Widespread clearings across most areas, except for residual cloud cover in the early morning in the east. In the Center: Instability along the Adriatic coast, with precipitation in Abruzzo and Molise (15-40 mm/24 hours); temperatures dropping by 2-3°C. In the South and on the Islands: Rain extending to the Gargano and the rest of the peninsular regions.
Sunday 25th. In the North: Sunny weather; lows reaching 4-5°C in the plains. In the Center: Cloudy, cool at dawn, and highs between 16-19°C. In the South and on the Islands: Residual precipitation (less than 5-10 mm/24 hours) in the southern peninsular areas, gradually subsiding.
Trend: From the beginning of the week, an anticyclonic field will expand, resulting in widespread atmospheric stability and temperatures rising by 3-4°C.
