The start of May in Italy promises to be quite eventful from a weather point of view. The week will start immediately in the sign of instability with possible rains and a little sun. Then, as the days go by, the arrival of cold air currents descending from Northern Europe will lead to the formation of a real Mediterranean vortex with important effects on many regions of Italy. Tomorrow, Monday 2 May, it will be characterized by extreme dynamism on the weather front. In fact, due to repeated drafts of fresh and unstable air at high altitude, thunderstorms are possible – especially during the afternoon – over the Alps and the nearby plains in extension then also to the inland areas of the Center up to Puglia and Basilicata. Similar speech also for the days of Tuesday 3 and Wednesday 4 May with alternation between dry and sunny breaks during the morning and an increase in instability during the afternoon hours. However, attention has been focused since Thursday 5 May – we read on ilmeteo.it – when a vast depression should start in the Northern European sector that will drive very cold currents first towards the British Isles and France and then also invest our country. The unstable currents will continue their journey going to “hook up” an area of low pressure already present between Sardinia and Sicily, giving it new strength and vigor: in short, an insidious cyclonic circulation risks taking place in the Mediterranean area. counterclockwise movement of the currents, the vortex will draw very hot air from the southern quadrants which, after crossing the sea and being loaded with humidity, will provide a surplus of fuel (potential energy) for extreme weather events. In the second part of the week, sometimes very abundant rainfall is not to be excluded, even in the form of thunderstorms with hail, which may affect in particular the regions of the Center North. time, that is the equivalent of the expected rainfall throughout the month. The soil, which has been dry for a long time now, may not be able to absorb the rain so sudden floods or flash floods in rather localized areas are not excluded. as the trajectory of the cyclone could undergo variations, triggering a wave of bad weather also on other sectors of our country.
