Italy: Italy's third heat wave of the year is expected to continue until at least July 20, with temperatures forecast to reach 43°C (109.4°F) in inland areas of Sardinia on Monday, according to meteorologist Lorenzo Tedici of iLMeteo.it. According to Anadolu Agency, after experiencing temperatures of 38°C to 40°C (100.4°F to 104°F) during the second heat wave, daily highs of 34°C to 35°C (93.2°F to 95°F) have now become the new baseline. Tedici highlighted that average daytime temperatures in June hovered around 30°C to 32°C (86°F to 89.6°F) in Italy three to four decades ago. In contrast, July highs in Milan have risen from approximately 33°C (91.4°F) in the last century to about 37°C (98.6°F) in recent years. Thunderstorms are anticipated mainly along the central and southern Apennines through Friday. Between Friday evening and Saturday, unstable weather is forecast across much of northern Italy and the Po Valley, potentially bringing locally heavy rainfall. Tedici explained that the storms will be drive n by cooler air moving eastward from Spain, which is expected to temporarily weaken the African anticyclone and trigger strong thermal contrasts. Following this brief period of instability, temperatures are predicted to rise again, with inland southwestern Sardinia forecast to see highs of 43°C (109.4°F) on Monday. Tedici advised residents to avoid going outdoors during the hottest and most humid hours of the day in the affected areas. Conditions are expected to ease slightly from Wednesday before another period of extreme heat is anticipated around July 17. Unlike the first two heat waves, which mainly affected central and northern Italy, the latest episode is expected to extend across southern Italy as well.
