High pressure will continue to dominate until Saturday, bringing unusually warm weather for this time of year. However, skies will be cloudy due to rising Saharan sand from the south. This suspended desert dust, especially over central and southern Italy, will be the prelude to worsening conditions expected on Sunday evening across Sardinia, Liguria, and Piedmont. On Monday, the first light rains are expected to mark the start of a period of severe weather.
On Monday, Tedici explains, Italy is expected to suffer "a real two-pronged attack: an intense wave of Saharan dust will rise from the south, combined with a mild and very humid air mass that will cause some scattered rain , while a front of cooler, stormy air will break in from the Atlantic. This mix should cause widespread worsening weather that will persist over our country for a few days. The focus," Tedici continues, "will be on the Tyrrhenian coast and the South in particular, but frequent rainfall in Northern Italy is not ruled out. The most obvious effect will be a drop in temperatures: the anomalous warm bubble of recent days will quickly deflate, bringing highs back to around 17-18°C.
Furthermore, Friday and Saturday will see a noticeable change in the color of the sky . "We will begin to see the first effects of the change in the form of desert dust. The skies will gradually become less clear and milkier due to the rising Saharan sand from the south. To be precise," says Tedici, "what we call suspended 'sand' is actually fine silt or silt, particles much smaller than actual grains of sand." As mentioned, this suspended desert dust, especially over the skies of central and southern Italy, will be the first sign of the worsening conditions expected for Sunday evening in Sardinia , Liguria, and Piedmont. "The first light rains are not out of the question in these areas, which, precisely because of the atmospheric dust, will be 'muddy. ' Practical advice is essential: avoid washing your car over the weekend, because it will get inexorably dirty already at the beginning of next week," say the experts.
