Thunderstorms over half of Italy and first frosts in the plains. From Wednesday a “Scandinavian blitz” will bring cold and thunderstorms to some areas of our country, a weather condition more similar to a winter climate than an autumn one.
According to the website www.ILmeteo.it, in fact, from Wednesday “a sudden rise in the high pressure of the Azores towards Iceland will favor the descent of very cold air masses from Scandinavia”. After a largely stable Tuesday, from Wednesday cooler air will begin to blow over Italy. The weather will tend to get worse on Romagna and subsequently on Marche and Abruzzo and by evening on most of the South.
The key phase of the raid is expected, however, on Thursday when Bora and Grecale winds will blow at almost 100 kilometers per hour on the middle and lower Adriatic, on the Ionian Sea and on the Tyrrhenian Sea. Showers and thunderstorms will hit the Adriatic regions while in the South they will concentrate with particular intensity on Sicily where storms are expected. On the rest of Italy, the expansion of high pressure will guarantee good weather with prevailing sun and clear skies.
With this irruption of cold air, temperatures will suffer a further drop, especially in nighttime values: from Friday in cities such as Turin, Milan, Bologna, Florence and Rome in the early morning they will measure 3-4 degrees with the first frosts ready to make their appeared in the flat peripheral areas of large cities. All this “in anticipation of a weekend characterized by a fairly stable atmosphere and with temperatures in a slight, but general increase in the maximum values”, concludes the meteorologist Marco Castelli.
